ACL Surgery Recovery —
Week by Week
A detailed guide to what to expect after ACL reconstruction — from surgery day through return to sport.
ACL reconstruction is one of the most common orthopedic procedures performed in the United States — and one that requires a significant commitment to rehabilitation for a successful outcome. This guide provides a general overview of the ACL recovery process. Your specific protocol may vary based on your graft type, any additional procedures performed, and your individual healing.
Always follow the specific rehabilitation protocol provided by Dr. Vasileff and your physical therapist. This general guide is for educational purposes — your individualized plan takes precedence.
Recovery Timeline
ACL reconstruction is outpatient surgery — you go home the same day. Expect your knee to be wrapped in a compression dressing and placed in a brace. You'll need someone to drive you home. Begin ice and elevation immediately to control swelling.
Focus on reducing swelling (ice 20 min every 2 hours), pain management, and waking up the quadriceps muscle. Straight-leg raises, quad sets, and ankle pumps begin immediately. Crutches for support — weight-bearing as tolerated in most cases.
Goal is to achieve full extension and 90° of flexion. Stationary biking (with seat raised high) typically begins around week 2–3. Continue quad strengthening. Swelling should be decreasing significantly.
Closed-chain exercises: leg press, step-ups, partial squats. Weight-bearing fully without crutches for most patients. Pool walking may begin if incisions are healed.
Single-leg exercises begin. Stationary cycling progresses to outdoor cycling. Most daily activities unrestricted. Swelling typically resolves. Hip and core strengthening integral at this stage.
Straight-line jogging typically begins at 3 months if strength and range of motion criteria are met. No cutting, pivoting, or sport-specific movements yet.
Agility drills, lateral movements, cutting, jumping, and sport-specific patterns are gradually introduced. Neuromuscular training and proprioception work are critical at this stage to prevent re-injury.
Return to competitive sport after passing functional testing — typically including limb symmetry testing, hop tests, and a sport-specific movement assessment. Average return is 6–9 months. Psychological readiness is evaluated alongside physical metrics.
Keys to a Successful Recovery
- Attend every physical therapy session — consistency is the single biggest predictor of outcome
- Don't rush return to sport — re-tear rates are significantly higher in patients who return too early
- Control swelling aggressively in the first 2 weeks — it is the enemy of early range of motion
- Communicate openly with Dr. Vasileff and your PT if something doesn't feel right
- Focus on the hip and core, not just the knee — proximal strength is essential for long-term stability
