What you're feeling

Smoking and other tobacco products affect how your body heals after orthopaedic surgery. You may notice that your recovery takes longer than expected. Your surgeon will ask about all forms of tobacco use, including smokeless tobacco, to understand your specific risks. This helps us plan the best care for you.

If you are having knee or hip replacement surgery, active smoking increases your risk of medical and surgical complications. Smokeless tobacco is also linked to worse outcomes after total knee replacement. It can lead to more problems during and after the operation, including a higher chance of needing revision surgery. You might experience increased pain or slower healing at the surgical site.

For shoulder surgery, such as rotator cuff repair, the number of years you have smoked and how long you have stopped smoking matter. Heated tobacco users often have healing results similar to those who smoke conventional cigarettes. You may feel stiffness or weakness in your shoulder as the tendon heals. Reaching behind your back to fasten a bra or tucking in a shirt may become difficult if healing is delayed.

If you have a scaphoid fracture in your wrist, using smokeless tobacco or smoking puts you at risk for nonunion. This means the bone may not heal properly. You might feel persistent pain in your wrist that does not go away with rest. Your surgeon will screen for these habits to identify risks early.

For anterior cruciate ligament reconstruction, smokeless tobacco use is associated with increased perioperative complications and revision surgery. You may face a higher risk of the graft failing or needing another operation. Preoperative screening considers these specific forms of tobacco use to optimize your outcome.

Contemporary techniques and biologic augmentation may help reduce the negative effects of smoking on spinal fusion after combined TLIF and posterolateral lumbar arthrodesis. However, avoiding tobacco remains the best way to support your body’s natural healing processes. Your surgeon may also evaluate non-tobacco nicotine dependence as part of your surgical optimization protocol. Understanding these factors helps you prepare for a smoother recovery journey.

What's actually happening

When you smoke, your body struggles to heal injured tissues. This affects your bones, tendons, and joints. Your surgeon needs to know if you use any form of tobacco. This includes cigarettes, smokeless tobacco, or heated tobacco products. All of these forms can slow down your recovery.

Your blood carries oxygen and nutrients to help repair damage. Smoking reduces this supply. For example, after a rotator cuff repair in the shoulder, the number of years you smoked and how long you stopped before surgery predict how well your tendon heals. Heated tobacco users face similar healing challenges as those who smoke conventional cigarettes.

Smokeless tobacco also causes problems. It is linked to worse outcomes after knee replacement surgery. It also increases the risk of complications and the need for revision surgery after anterior cruciate ligament reconstruction. This ligament stabilizes your knee. Your surgeon may ask about smokeless tobacco use if you have a scaphoid fracture in your wrist. This helps identify patients at risk for nonunions, where the bone fails to join together.

Even if you do not smoke, nicotine dependence can affect your healing. Orthopaedic surgeons should evaluate non-tobacco nicotine dependence during your preparation for knee replacement. Active smokers face a higher risk of medical and surgical complications during elective hip or knee arthroplasty than non-smokers. Smoking is associated with a higher risk for complications than smokeless tobacco use.

Modern techniques and biologic aids may help reduce these risks. This is especially true for complex spinal fusion surgeries. However, avoiding tobacco remains the best way to support your body’s natural healing process. Your surgeon wants you to heal well and avoid extra procedures.

What to expect

Smoking affects how your body heals after orthopaedic surgery. It increases your risk of medical and surgical complications. This is true for elective knee or hip joint replacement. It also applies to procedures like rotator cuff repair, scaphoid fracture care, and anterior cruciate ligament reconstruction. Your surgeon will likely ask about all forms of tobacco use. This includes smokeless tobacco and cigarettes. They may also check for nicotine dependence even if you do not smoke.

Your healing depends on how much you smoke and how long you stop before surgery. For tendon repairs, the number of pack-years and the duration of cessation predict healing. Heated tobacco users face worse outcomes similar to conventional cigarette smokers. Smokeless tobacco use is linked to higher rates of complications and revision surgery after knee replacement and ligament reconstruction. Smoking carries a higher risk of complications than smokeless tobacco use.

Despite these risks, modern techniques may help. Biologic treatments can sometimes reduce the negative impact of smoking on bone fusion after complex back surgery. However, smokeless tobacco still worsens outcomes after knee replacement. If you continue to use tobacco, your recovery may be longer and more difficult. You might experience more pain or need additional procedures. If you stop using tobacco before surgery, your chances of a smooth recovery improve. Your surgeon wants to help you heal well. Be honest about your habits so they can plan the best care for you.

4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 -- Other Terms and Conditions.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
