ACL (Anterior Cruciate Ligament) surgery is recommended when non-surgical treatments fail to restore knee stability and function following an ACL tear. While surgery is a key step in regaining mobility, understanding the recovery process is just as important for a successful rehabilitation after your ACL surgery recovery.
At Northwest Extremity Specialists, our orthopedic surgeons have created this comprehensive guide to help you navigate ACL recovery. If you have specific concerns about ACL surgery recovery, contact our office for personalized care.
Immediate Post-Op Phase (First 2 Weeks After Surgery)
Most patients are discharged the same day as surgery, though some may require an overnight hospital stay for monitoring. During this phase:
- Low-grade fever (up to 101°F) is common for 4 to 5 days. If the fever is higher or persists beyond this timeframe, notify your surgeon to ensure a smooth ACL surgery recovery.
- Pain and swelling are expected. Manage discomfort with prescribed pain medications, ice therapy, and leg elevation.
- Knee brace or immobilizer will be provided to maintain proper alignment and support healing.
- Crutches are necessary for the first 7 to 10 days to prevent weight-bearing on the operated leg. Using them correctly is crucial for protecting the reconstructed ligament during your ACL surgery recovery.

Mid-Term Recovery (Weeks 3 to 12)
During this phase, you will transition toward greater independence with a focus on strength, flexibility, and mobility restoration as part of your ACL surgery recovery.
- Weight-bearing gradually increases under the guidance of your physical therapist and surgeon.
- Twisting movements and full knee bends should be avoided for at least six weeks.
- Daily activities such as walking and driving may resume depending on progress. However, always consult your healthcare team before returning to normal routines during ACL surgery recovery.
The National Institutes of Health (NIH) highlights that progressive physical therapy significantly improves ACL surgery outcomes and prevents complications.
Long-Term Rehabilitation (3 to 6 Months)
As knee function improves, functional exercises will be introduced to mimic daily movements like:
- Walking
- Climbing stairs
- Squatting
For athletes, sport-specific training may begin during this phase. This process gradually reintroduces movement patterns related to your sport to restore agility and strength.
- Running is not recommended until at least five months post-surgery as a part of the ACL surgery recovery process.
- Swimming (arms only) may be permitted within two to three months, depending on progress.
The Mayo Clinic provides detailed insights on what to expect during ACL rehabilitation and how to optimize recovery.
Full Recovery (6 to 12 Months)
Full recovery after ACL reconstruction takes six to twelve months, depending on individual progress. Patients must:
- Continue physical therapy
- Avoid high-impact sports until cleared by their surgeon
- Maintain consistent follow-up care
For guidance on returning to sports safely after ACL surgery recovery, review the American Orthopaedic Society for Sports Medicine (AOSSM).
