Overview¶
Nutritional supplementation serves as a targeted adjunct to standard orthopaedic care, particularly for geriatric patients who are unable to exercise [2]. While peptide supplements should not currently be recommended as a replacement or adjunct for existing standard of care due to the lack of robust efficacy and safety data [1], specific interventions demonstrate distinct clinical benefits. Intravenous peri-operative protein or amino acid supplementation offers benefits for total joint arthroplasty, although effects on muscle strength and function remain mixed [3]. For malnourished patients, nutrition consultation and perioperative supplementation with amino acids and micronutrients are readily available interventions that orthopaedic surgeons can select [11]. The use of low-cost commercially available amino acid supplements resulted in fewer overall complications postoperatively and was a low-risk intervention for the patient population [19]. Furthermore, nutritional supplementation has been shown to markedly reduce hospital costs by reducing rates of ICU admissions, hospital-associated complications, and hospital-acquired infections [13].
In the management of osteoarthritis, glucosamine and chondroitin sulfate possess an excellent safety profile and may serve as an initial treatment modality [4]. Glucosamine sulfate has the potential to relieve pain and improve function with low side effects, though unanswered questions regarding long-term effects and dosage preclude a definitive endorsement [10]. The combination of non-steroidal anti-inflammatory drugs and glucosamine sulfate supports efficacy in reducing pain, improving function, and possibly regulating joint damage in knee osteoarthritis [7]. Supplementation of n-3 polyunsaturated fatty acids is effective to relieve pain and improve joint function in patients with osteoarthritis [6]. Specifically, supplementation with omega-3 polyunsaturated fatty acids for 3-4 months reduces patient-reported joint pain intensity, minutes of morning stiffness, number of painful and/or tender joints, and NSAID consumption [8]. Glucosamine and chondroitin sulfate may be considered reasonable treatment options as part of a multimodal approach for symptomatic primary hand osteoarthritis if the cost is not prohibitive [14].
For musculoskeletal injuries and surgical optimization, adjuvant oral supplementation containing collagen, hyaluronic acid, chondroitin sulfate, and plasma proteins may increase the efficacy of physical therapy by shortening the time needed to return to pre-injury activity and reducing analgesic consumption after anterior cruciate ligament reconstruction [5]. Conditionally essential amino acid supplementation has a protective effect against common complications and early skeletal muscle wasting after operative fixation of extremity and pelvic fractures [9]. Perioperative nutritional optimization has been associated with improved outcomes for patients undergoing spine surgery, but additional investigation is needed to determine effective perioperative nutritional protocols [23]. Substantial barriers such as inconsistent protocols and patient nonadherence remain in nutritional optimization for spine surgery, highlighting the need for multifactorial assessment and standardization of multidisciplinary nutritional protocols [22]. In athletic populations, the appropriate use of some dietary supplements can benefit the athlete, while others may harm the athlete’s health, performance, and/or livelihood and reputation if an antidoping rule violation results [12]. Recommendations for data capture relating to female athlete population characteristics, injuries, illnesses, and other health consequences will improve the quality of epidemiological studies to inform better injury and illness prevention strategies [15].
How It Works¶
Mechanisms of Action¶
Glucosamine exerts analgesic properties by stimulating hyaluronic acid production in human osteoarthritic synovium [32]. Omega-3 fatty acids protect cartilage from acute injury by reducing the mechanical sensitivity of chondrocytes [16].
Perioperative and Postoperative Recovery¶
Perioperative essential amino acid supplementation prevents rectus femoris muscle atrophy and accelerates early functional recovery after total knee arthroplasty [30]. Protein supplementation mitigates muscle atrophy in the postoperative period following ACL reconstruction, total hip arthroplasty, total knee arthroplasty, and surgical treatment of hip fracture [24]. Intravenous perioperative protein or amino acid supplementation offers benefits for total joint arthroplasty, although effects on muscle strength and function are mixed [3]. Protein supplementation is a low-cost intervention that is easy to incorporate into perioperative management; its beneficial effects on muscle strength could potentially reduce the risk of longer-term complications such as falls and periprosthetic fracture [20]. Oral nutritional supplementation and dietetic assistance represent low-risk interventions that may improve morbidity and mortality in older people after hip fracture [17].
Osteoarthritis and Joint Pain¶
Collagen peptides provide significant pain relief in patients with knee osteoarthritis compared to placebo [27]. An eight-week collagen-based supplement has a positive effect on pain, quality of life levels, and some functional test results in patients with meniscopathy [25]. The evidence supports the efficacy of glucosamine sulfate in reducing pain, improving function, and possibly regulating joint damage in knee osteoarthritis [7]. Glucosamine sulfate has the potential to relieve pain and improve function with low side effects, though unanswered questions regarding long-term effects and dosage preclude a definitive endorsement [10]. The excellent safety profile of glucosamine and chondroitin sulfate should be discussed with patients, and they may serve a role as an initial treatment modality for many osteoarthritis patients [4].
Musculoskeletal Function and Sarcopenia¶
Specific nutritional supplementation with vitamin D and leucine-enriched whey protein provides proof-of-principle that it might benefit geriatric patients, especially those who are unable to exercise [2]. With protein supplementation, protein intakes at amounts greater than ~1.6 g/kg/day do not further contribute to resistance training-induced gains in fat-free mass [18]. Subacromial injection of hydrolyzed collagen is effective in reducing pain and supporting functional recovery in patients with rotator cuff tendinopathy, with effects observed after the first injection and persisting up to six months [29].
Limitations and Safety¶
Patients do not benefit from creatine supplementation during the first 12 weeks of rehabilitation after anterior cruciate ligament reconstruction [26]. The appropriate use of some supplements can benefit the athlete, but others may harm the athlete’s health, performance, and/or livelihood and reputation if an antidoping rule violation results [12].
What the Evidence Shows¶
Perioperative and Postoperative Supplementation¶
Intravenous protein or amino acid supplementation offers benefits for total joint arthroplasty, although effects on muscle strength and function remain mixed [3]. For malnourished orthopaedic patients, perioperative nutritional optimization with amino acids and micronutrients serves as a readily available intervention [11]. Integrating targeted nutrition into prehabilitation pathways may help reduce complications and support faster functional gains in total joint arthroplasty [21]. In spine surgery, perioperative nutritional optimization has been associated with improved outcomes, but additional investigation is needed to determine effective protocols [23]. Substantial barriers to nutritional optimization in this population include inconsistent protocols and patient nonadherence [22]. Regarding hip fractures, a comprehensive balanced nutrition supplement resulted in lower complication rates and mortality at 120 days postoperatively [31]. Additionally, the use of a low-cost commercially available amino acid supplement resulted in fewer overall complications postoperatively and was a low-risk intervention for the patient population [19].
Osteoarthritis and Joint Health¶
The evidence supports the efficacy of non-steroidal anti-inflammatory drugs and glucosamine sulfate in reducing pain, improving function, and possibly regulating joint damage in knee osteoarthritis [7]. If the cost is not prohibitive, glucosamine and chondroitin sulfate may be considered reasonable treatment options as part of a multimodal approach for symptomatic primary hand osteoarthritis [14]. Oral chondroitin is more effective than placebo on relieving pain and improving physical function, while glucosamine showed an effect on stiffness outcome in osteoarthritis [33]. Collagen peptides demonstrate significant pain relief in patients with knee osteoarthritis compared to those who received placebo [27]. An eight-week collagen-based supplement had a positive effect on pain and quality of life levels and some functional test results in patients with meniscopathy [25]. EPA supplementation could offer a promising strategy for preventing post-traumatic osteoarthritis progression following acute cartilage injuries [16].
Sports Medicine and Rehabilitation¶
Specific nutritional supplementation alone might benefit geriatric patients, especially those who are unable to exercise, as shown by a vitamin D and leucine-enriched whey protein study [2]. Adjuvant oral supplementation containing collagen, hyaluronic acid, chondroitin sulfate, and plasma proteins may increase the efficacy of physical therapy by shortening the time needed to return to pre-injury activity and reducing analgesic consumption after ACL reconstruction [5]. The appropriate use of some dietary supplements can benefit the athlete, but others may harm the athlete’s health, performance, and/or livelihood and reputation if an antidoping rule violation results [12]. With protein supplementation, protein intakes at amounts greater than ~1.6 g/kg/day do not further contribute to resistance training-induced gains in fat-free mass in healthy adults [18]. Patients do not benefit from creatine supplementation during the first 12 weeks of rehabilitation after ACL reconstruction [26]. Subacromial injection of hydrolyzed collagen was effective in reducing pain and supporting functional recovery in patients with rotator cuff tendinopathy, with effects observed after the first injection and persisting up to six months [29].
Practical Considerations¶
Perioperative and Fracture Care¶
In the management of hip fractures, a comprehensive balanced nutrition supplement is associated with lower complication rates and mortality at 120 days postoperatively [31]. Oral nutritional supplementation and dietetic assistance represent low-risk interventions that may improve morbidity and mortality in older people with hip fractures [17].
For spine surgery, substantial barriers to nutritional optimization include inconsistent protocols and patient nonadherence. These challenges highlight the need for multifactorial assessment and standardization of multidisciplinary nutritional protocols [22].
Osteoarthritis and Joint Health¶
If the cost is not prohibitive, glucosamine and chondroitin sulfate products may be considered reasonable treatment options as part of a multimodal approach for symptomatic primary hand osteoarthritis [14].
Rehabilitation and Sarcopenia¶
Specific nutritional supplementation alone might benefit geriatric patients with sarcopenia, especially those who are unable to exercise [2].
