Overview

Most shoulders experiencing early motion loss following rotator cuff repair recover function without requiring capsular release [1]. For adhesive capsulitis of the glenohumeral joint, arthroscopic capsular release is a reliable method to restore motion with minimum morbidity in carefully selected patients [2]. Circumferential capsular release improves range of motion in shoulder pathologies, particularly where no bony deformities exist [9]. In the short term, patients undergoing this procedure experience almost immediate relief of pain and symptoms with dramatic improvements in range of motion, outcomes not seen with injections or physiotherapy [3].

Surgical intervention for adhesive capsulitis is typically considered after 9 to 12 months of failed nonsurgical management, which includes arthroscopic capsular release, manipulation under anesthesia (MUA), or both [8]. Both manipulation and capsular release with manipulation significantly improved range of motion and produced satisfactory functional outcomes for shoulder stiffness concomitant with rotator cuff repair [7]. Arthroscopic capsular release is a very cost-effective procedure that can restore relatively normal function and health-related quality of life in most patients with shoulder contracture within six months of surgery [33]. However, the quality of evidence regarding capsular release for adhesive capsulitis is low, and data demonstrate little benefit for a capsular release instead of, or in addition to, manipulation under anesthesia [6].

Initial management of posterior capsular contracture should be nonsurgical, emphasizing range-of-motion stretching [4]. Isolated arthroscopic debridement and capsular release may not provide substantial benefit to justify its use in most patients with glenohumeral arthritis [5]. Routine capsular closure cannot be universally recommended for interportal capsulotomy in hip arthroscopy for femoroacetabular impingement [14].

Anatomy & Pathophysiology

Pathophysiology of Stiffness: The pathophysiology of frozen shoulder differs between the upper and lower parts of the joint capsule [31]. Patients with idiopathic and post-traumatic shoulder stiffness have better outcomes than patients with postsurgical stiffness following arthroscopic capsular release [44]. Performing manipulation before reaching Stage 4 may result in more favorable outcomes for patients with adhesive capsulitis [36]. Evaluating shoulder stiffness by measuring releasing force proved to be feasible [36]. Most shoulders with early motion loss after rotator cuff repair recover motion and rarely require capsular release [1].

Kinematics and Translation: Posterior glenohumeral joint capsule contracture alters humeral head translations and/or the humeral axis of rotation during movement, creating conditions that lead to joint pathology [37]. The inferior capsular region has a more significant comparative strain during glenohumeral rotational motion than has been documented in previous studies [39]. Increased glenohumeral joint loads due to a full-thickness supraspinatus tear can be reversed with rotator cuff repair in a dynamic biomechanical cadaveric model [27]. Superior capsular reconstruction using the long head of the biceps tendon is biomechanically effective in reducing posterosuperior translation of the humeral head in the setting of a massive irreparable rotator cuff tear [38]. Fascia lata allograft superior capsule reconstruction restores glenohumeral translation but alters glenohumeral kinematics by shifting the humeral head inferiorly compared to the intact rotator cuff state at low levels of abduction [29]. The presence of rotator cuff tissue over the half superior portion of the humeral head preserves function despite tear size, whereas its absence causes an inevitable upward shift of the humeral head and significant impairment of glenohumeral abduction function [35]. Significant alterations in kinematic parameters in multidirectional instability patients cannot be completely normalized by physiotherapy only [42].

Implant and Measurement Considerations: A gained understanding of the consequences of implant head shape in total shoulder arthroplasty may guide future surgical implant choice for better recreation of native shoulder kinematics [26]. No correlations between functional outcomes and radiographic shoulder findings were identified at mid-term follow-up for superior capsular reconstruction using xenograft [32]. There is high variability in quantitative measurement techniques in glenohumeral capsular measurements for shoulder instability, indicating a need for standardization of methods to allow for cross-study analysis [45]. Measurements of shoulder range of motion using Kinect show excellent agreement with those taken using a goniometer [40]. The anatomical structure of passive shoulder restraints has no impact on the difference in passive joint position sense values between external and internal rotation [30]. A thorough understanding of shoulder physical examination and specific diagnostic tests, emphasizing history-taking and examination, is important to ensure diagnostic accuracy and optimize patient outcomes [43]. The Single Alpha-numeric Evaluation (SANE) is valid for a range of common shoulder diagnoses to assess patient outcomes across operative and nonoperative treatment [46].

Classification

Indications and Timing: Surgical intervention for adhesive capsulitis is typically considered after 9 to 12 months of failed nonsurgical management and includes arthroscopic capsular release, manipulation under anesthesia (MUA), or both [8]. Initial management of posterior capsular contracture should be nonsurgical, emphasizing range-of-motion stretching [4]. Most shoulders with early motion loss after rotator cuff repair recover motion and rarely require capsular release [1].

Efficacy and Outcomes: Arthroscopic capsular release is a reliable method for restoring motion with minimum morbidity in carefully selected patients with adhesive capsulitis of the glenohumeral joint [2]. In the short term, patients who have had capsular release experience almost immediate relief of pain and symptoms and dramatic improvements in range of motion, which has not been seen with injections or physiotherapy [3]. Both manipulation and capsular release with manipulation significantly improved range of motion and produced satisfactory functional outcomes for shoulder stiffness concomitant with rotator cuff repair [7]. The long-term results of arthroscopic capsular release in frozen shoulder were confirmed in a cohort of 255 patients [11]. Circumferential capsular release improves range of motion in shoulder pathologies, particularly where no bony deformities exist [9]. Each segment of the joint capsule affects range of motion in all directions, supporting the need for whole-joint capsular release in patients with frozen shoulder [10].

Comparative Evidence and Limitations: The quality of evidence available regarding capsular release for adhesive capsulitis is low, and data demonstrate little benefit for a capsular release instead of, or in addition to, manipulation under anesthesia (MUA) [6]. In a broad group of patients with recalcitrant adhesive capsulitis, the addition of posterior capsular release did not improve patient function or range of motion over anterior capsular release alone at 6 months [15]. Isolated arthroscopic debridement and capsular release may not provide substantial benefit to justify its use in most patients with glenohumeral arthritis [5].

Other Considerations: Routine capsular closure cannot be universally recommended for interportal capsulotomy in hip arthroscopy for femoroacetabular impingement [14].

Clinical Presentation

Most patients with early motion loss following rotator cuff repair recover motion spontaneously and rarely require capsular release [1]. In contrast, arthroscopic capsular release is a reliable method for restoring motion with minimum morbidity in carefully selected patients with adhesive capsulitis of the glenohumeral joint [2]. Surgical intervention for adhesive capsulitis is typically considered after 9 to 12 months of failed nonsurgical management and includes Arthroscopic capsular release, Manipulation under anesthesia (MUA), or Both, all of which are efficacious [8]. Initial management of posterior capsular contracture should remain nonsurgical, emphasizing range-of-motion stretching [4].

In the short term, patients undergoing capsular release experience almost immediate relief of pain and symptoms with dramatic improvements in range of motion, outcomes not seen with injections or physiotherapy [3]. Arthroscopic capsular release produces early symptom improvement in primary frozen shoulder [12] and results in an overall rapid significant improvement for both primary and secondary frozen shoulder [13]. Patients with idiopathic adhesive capsulitis experience significant reductions in pain, improvements in range of motion, and improved overall shoulder function within the first postoperative week [25]. Long-term results in frozen shoulder have been confirmed in a cohort of 255 patients [11].

Circumferential capsular release improves range of motion in shoulder pathologies, particularly where no bony deformities exist [9]. Each segment of the joint capsule affects range of motion in all directions, supporting the need for whole-joint capsular release [10]. Arthroscopic release resulted in normal motion in all cases of postoperative stiffness following arthroscopic rotator cuff repair [20]. Both manipulation and capsular release with manipulation significantly improved range of motion and produced satisfactory functional outcomes in the treatment of shoulder stiffness concomitant with rotator cuff repair [7]. Arthroscopic capsular release can be a valuable adjunct for patients presenting with cuff tears and stiffness, yielding similar outcomes as repairs in cuff tears without stiffness [28].

The quality of evidence available is low, and data demonstrate little benefit for a capsular release instead of, or in addition to, manipulation under anesthesia (MUA) [6]. In a broad group of patients with recalcitrant adhesive capsulitis, the addition of the posterior capsular release did not improve patient function or range of motion over anterior capsular release alone at 6 months [15]. Isolated arthroscopic debridement and capsular release may not provide substantial benefit to justify its use in most patients with glenohumeral arthritis [5]. However, arthroscopic debridement with capsular release may provide a window of improved symptoms and function before deterioration of the joint leads to a more significant operation, especially in younger patients with mild or moderate osteoarthritic changes [17]. Arthroscopic capsular release provided significant pain relief and improvement in shoulder function in patients with frozen shoulder regardless of the timing of surgery [18].

Investigations

MRI: Axillary capsular enhancement and rotator interval joint capsule thickening demonstrate the highest diagnostic accuracy among seven informative MRI features identified for adhesive capsulitis of the shoulder [48]. Interventional microadhesiolysis for adhesive capsulitis results in reduced joint capsule thickness and effusion visible on MRI findings [34].

Other Considerations: Most shoulders with early motion loss after rotator cuff repair recover motion and rarely require capsular release [1]. Initial management of posterior capsular contracture should be nonsurgical, emphasizing range-of-motion stretching [4]. Circumferential capsular release improves range of motion in shoulder pathologies, particularly where no bony deformities exist [9], as each segment of the joint capsule affects range of motion in all directions, supporting the need for whole-joint capsular release [10]. Arthroscopic capsular release is a reliable method for restoring motion with minimum morbidity in carefully selected patients with adhesive capsulitis of the glenohumeral joint [2]. In the short term, patients who have had capsular release experience almost immediate relief of pain and symptoms and dramatic improvements in range of motion, which has not been seen with injections or physiotherapy [3]. Arthroscopic capsular release produces early symptom improvement in primary frozen shoulder [12] and results in an overall rapid significant improvement for both primary and secondary frozen shoulder [13]. The long-term results of arthroscopic capsular release in frozen shoulder were confirmed in a cohort of 255 patients [11], with range of motion significantly greater on the affected side than on the unaffected side after surgery for frozen shoulder [10]. Arthroscopic release resulted in normal motion in all cases of postoperative stiffness following arthroscopic rotator cuff repair [20]. Both manipulation and capsular release with manipulation significantly improved range of motion and produced satisfactory functional outcomes for shoulder stiffness concomitant with rotator cuff repair [7]. Manipulation under anesthesia (MUA) combined with capsular distension and countertraction reduces the need for a second MUA and results in a faster improvement in functional outcome (CMS score) and reduction of pain (VAS score) compared with MUA alone or MUA with capsular distension [21]. The quality of evidence available is low and the data available demonstrate little benefit for a capsular release instead of, or in addition to, manipulation under anesthesia (MUA) for adhesive capsulitis [6]. Isolated arthroscopic debridement and capsular release may not provide substantial benefit to justify its use in most patients with glenohumeral arthritis [5]. However, arthroscopic debridement with capsular release may provide a window of improved symptoms and function before deterioration of the joint leads to a more significant operation, especially in younger patients with mild or moderate osteoarthritic changes [17].

Treatment

Non-Operative

Conservative treatment serves as the primary choice for shoulder stiffness, emphasizing range-of-motion stretching as the initial management for posterior capsular contracture [4]. Most shoulders with early motion loss following rotator cuff repair recover motion and rarely require capsular release [1]. Surgical intervention for adhesive capsulitis is typically considered only after 9 to 12 months of failed nonsurgical management [8].

Operative

Indications: Arthroscopic capsular release is indicated for carefully selected patients with adhesive capsulitis of the glenohumeral joint who remain refractory to conservative measures [2]. Routine capsular closure cannot be universally recommended for interportal capsulotomy in hip arthroscopy for femoroacetabular impingement [14]. Isolated arthroscopic debridement and capsular release may not provide substantial benefit to justify its use in most patients with glenohumeral arthritis [5].

Surgical Approach / Technique: Circumferential capsular release improves range of motion in shoulder pathologies, particularly where no bony deformities exist [9]. Each segment of the joint capsule affects range of motion in all directions, supporting the need for whole-joint capsular release [10]. Posterior extended capsular release might not be necessary in arthroscopic surgery for shoulder stiffness [41]. Both manipulation and capsular release with manipulation significantly improved range of motion and produced satisfactory functional outcomes for shoulder stiffness concomitant with rotator cuff repair [7]. MUA combined with capsular distension and countertraction reduces the need for a second MUA compared with MUA alone or MUA with capsular distension [21].

Adjuncts: MUA combined with capsular distension and countertraction results in a faster improvement in functional outcome (CMS score) compared with MUA alone or MUA with capsular distension [21]. This combined approach also results in a reduction of pain (VAS score) compared with MUA alone or MUA with capsular distension [21].

Other Considerations: Arthroscopic capsular release is preferred over manipulation under anesthesia due to risks associated with manipulation [16]. The quality of evidence available is low and the data available demonstrate little benefit for a capsular release instead of, or in addition to, manipulation under anesthesia (MUA) [6]. In the short term, patients who have had capsular release experience almost immediate relief of pain and symptoms and dramatic improvements in range of motion, which has not been seen with injections or physiotherapy [3]. Arthroscopic capsular release provided significant pain relief and improvement in shoulder function in patients with frozen shoulder regardless of the timing of surgery [18]. The long-term results of arthroscopic capsular release in frozen shoulder were confirmed in a cohort of 255 patients [11]. Stepwise rehabilitation is mandatory after capsular release for shoulder stiffness [16].

Complications

Stiffness / Arthrofibrosis: Arthroscopic capsular release is a reliable method for restoring motion with minimum morbidity in carefully selected patients with adhesive capsulitis [2]. Patients experience almost immediate relief of pain and symptoms with dramatic short-term range of motion improvements, surpassing outcomes seen with injections or physiotherapy [3]. This intervention produces early symptom improvement in primary frozen shoulder and results in rapid, significant improvement for both primary and secondary cases [12, 13]. Long-term results in a series of 255 patients confirm the durability of arthroscopic capsular release for frozen shoulder [11]. Surgical intervention is typically reserved for cases where nonsurgical management fails after 9 to 12 months [8]. While data demonstrate little benefit for capsular release over manipulation under anesthesia (MUA) for adhesive capsulitis [6], isolated arthroscopic debridement and release may not justify use in most patients with glenohumeral arthritis [5]. Most shoulders with early motion loss after rotator cuff repair recover motion and rarely require capsular release [1]. Evidence supports whole-joint capsular release as each segment of the joint capsule affects range of motion in all directions [10]. Arthroscopic posteromedial capsular release for knee flexion contractures yields encouraging results comparable to open posterior studies [24]. Posterior capsular release using an osteotome during total knee arthroplasty is safe and effective for posterior contractures without neurovascular risk when standard technique is used [53]. For knee extension deficits after anterior cruciate ligament reconstruction, arthroscopic posterior capsular release significantly improves extension and patient-reported outcomes at 6 months and 2 years [60].

Instability: A new capsular closure technique for the hip allows the joint capsule to close more tightly, effectively reducing early postoperative dislocation rates [19]. Complete capsular closure is the superior management technique based on greater expected value compared to incomplete closure [54]. Complete capsular closure restores native anatomy, improves patient-reported outcomes, and reduces complications and revision surgery rates compared to incomplete closure in hip arthroscopy [57]. Although one study of 72 hips found no significant clinical differences between healed and unhealed capsules overall, the preponderance of evidence from multiple systematic reviews favors capsular closure due to improved outcomes and reduced revision surgery [58]. Routine capsular repair does not lead to superior outcomes compared with nonrepair following arthroscopic femoroacetabular impingement correction with labral repair [22]. However, routine capsular repair may be beneficial in younger, active patients and potentially lead to inferior outcomes in female patients following the same procedure [22]. In a series of 9 shoulders with severe capsular deficiency treated with open anterior capsular reconstruction, 45% remained completely stable at 3.8 years [61].

Other Considerations: Extension minimizes volar capsular space volume and may be essential for preventing flexion contractures in the proximal interphalangeal joint [55]. The indications, risks, and benefits for surgical treatment of chronic olecranon bursitis are incompletely defined [56]. Clinical results for the docking technique for lateral ulnar collateral ligament reconstruction are comparable with previously reported studies and show a low complication rate [62].

Recovery

Light activity (weeks): Patients typically resume desk work and light activities of daily living within the timeframe associated with early symptom improvement, which occurs almost immediately following arthroscopic capsular release for primary frozen shoulder [3, 12]. In pediatric populations with shoulder contracture secondary to brachial plexus palsy, subscapularis-sparing isolated capsular release improves external rotation and functional scores without loss of active internal rotation, facilitating early functional engagement [52].

Full activity (months): Young patients undergoing anterior stabilization procedures can expect the return of subscapularis function by 8 weeks post-surgery [49]. For patients with traumatic anterior instability of the shoulder, 65% achieve a return to more than 90% of preinjury activity levels in judo following a modified inferior capsular shift [51]. Superior capsular reconstruction demonstrates significant improvement in pain and range of motion in the short- and mid-term follow-up periods, though evidence for improved muscle strength and return-to-play rates remains limited [50].

Complete recovery / outcome plateau (months): Arthroscopic capsular release produces early symptom improvement and rapid significant overall improvement for both primary and secondary frozen shoulder, with outcomes stabilizing as patients transition from initial relief to sustained functional gains [8, 13]. In the context of adhesive capsulitis, data demonstrate little benefit for capsular release over manipulation under anesthesia (MUA), with both modalities producing satisfactory functional outcomes for shoulder stiffness concomitant with rotator cuff repair [6, 7]. Most shoulders with early motion loss after rotator cuff repair recover motion and rarely require capsular release, indicating a natural plateau of recovery without surgical intervention [1].

Rehabilitation protocol: Stepwise rehabilitation is mandatory after capsular release to ensure optimal outcomes [16]. Initial management of posterior capsular contracture should be nonsurgical, emphasizing range-of-motion stretching before considering surgical options [4]. Conservative treatment remains the primary choice for shoulder stiffness, with manipulation under anesthesia or arthroscopic capsular release indicated only for refractory cases [16].

Functional milestones: In the short term, patients who have had capsular release experience almost immediate relief of pain and symptoms and dramatic improvements in range of motion, which has not been seen with injections or physiotherapy [3]. Both manipulation and capsular release with manipulation significantly improved range of motion and produced satisfactory functional outcomes for shoulder stiffness concomitant with rotator cuff repair [7]. Arthroscopic capsular release is a reliable method for restoring motion with minimum morbidity in carefully selected patients with adhesive capsulitis [2].

Other Considerations: Arthroscopic capsular release is preferred over manipulation under anesthesia due to risks associated with manipulation [16]. Isolated arthroscopic debridement and capsular release may not provide substantial benefit to justify its use in most patients with glenohumeral arthritis [5]. Routine capsular repair did not lead to superior outcomes compared with a nonrepaired group following arthroscopic femoroacetabular impingement correction with labral repair, though it may be beneficial in younger, active patients and may lead to inferior outcomes in female patients [22]. Both full and partial posterior capsular release show similar clinical usefulness for increasing the medial component gap at extension and reducing component gap mismatch in posterior-stabilized total knee arthroplasty [23]. The results of arthroscopic posteromedial capsular release for knee flexion contractures compare well to data presented in open posterior capsular release studies [24]. Subscapularis-sparing isolated capsular release does not improve anterior elevation in children with shoulder contracture secondary to brachial plexus palsy [52].

(10.1007/s00167-019-05399-1)
  • [L1] The meta-analysis and expected-value decision analysis showed hip capsule complete closure as the superior capsular management technique on the basis of greater expected value than incomplete capsular closure. (10.1016/j.arthro.2024.11.080)
  • [L5] Extension minimizes volar capsular space volume and may be essential for preventing flexion contractures. (10.1016/j.jht.2024.12.015)
  • [L3] The indications, risks, and benefits for surgical treatment are incompletely defined. (10.1016/j.jhsa.2010.12.030)
  • [L5] Complete capsular closure should be embraced as the standard of care, as it restores native anatomy, improves patient-reported outcomes, and reduces complications and revision surgery rates compared to incomplete closure. (10.1016/j.arthro.2024.12.012)
  • [L5] Although a single study of 72 hips found no significant differences in clinical outcomes between healed and unhealed capsules overall, the preponderance of evidence from multiple systematic reviews still favors capsular closure due to improved outcomes and less revision surgery. (10.1016/j.arthro.2025.02.023)
  • [L4] Arthroscopic posterior capsular release resulted in significant improvement of knee extension and patient reported outcome scores at 6 month and 2 years postoperatively. (10.1177/2325967123s00125)
  • [L4] In our series 9 shoulders (45%) remained completely stable at 3.8 years. (10.1016/j.arthro.2011.07.002)
  • [L4] Clinical results are comparable with previously reported studies with a low complication rate. (10.1016/j.jse.2011.04.033)
