Recovering from anterior cruciate ligament (ACL) surgery takes time, patience, and a well-planned rehabilitation program. Whether your injury happened on the field, during a workout, or in daily life, knowing what to expect after surgery can help you prepare for each stage of recovery and return to your activities with confidence.

What to Expect Immediately After Surgery
Rest and knee protection are key in the first few days following ACL reconstruction. You’ll likely experience swelling, discomfort, and limited mobility. Your surgeon may recommend:
- Using crutches to limit weight-bearing
- Applying ice to reduce swelling
- Keeping the leg elevated when resting
- Wearing a knee brace as instructed
Your physical therapist will begin gentle exercises to maintain blood flow, prevent stiffness, and restore range of motion.
The Role of Physical Therapy in ACL Recovery
Physical therapy plays a central role in regaining strength, stability, and function in the knee. Therapy typically begins within the first week after surgery and progresses in phases:
- Early Recovery Phase (Weeks 1–4)
- Focus on reducing swelling and regaining full extension
- Gentle range-of-motion exercises
- Isometric quadriceps and hamstring activation
- Strengthening Phase (Weeks 4–12)
- Building strength in the quadriceps, hamstrings, and hip muscles
- Improving balance and coordination
- Gradual increase in weight-bearing activities
- Advanced Strength and Agility Phase (Months 3–6)
- Continued flexibility and stability work
- Sport-specific and functional movement training
- Plyometric and agility drills for athletes

4. Return-to-Activity Phase (Months 6–9+)
- Final assessments to ensure knee stability and readiness
- Gradual reintroduction to sport or high-impact activities
Common Challenges During Recovery
ACL surgery recovery is different for everyone, but some common challenges include:
- Swelling and stiffness: Often improved with ice, compression, and guided exercises
- Quadriceps weakness: Strengthening is crucial to protect the knee joint
- Fear of re-injury: Confidence-building exercises and gradual progression help reduce anxiety
Your physical therapist will monitor your progress and adjust your program to keep you moving forward safely.
Tips for a Successful Recovery
- Attend all physical therapy sessions and complete your home exercise program.
- Maintain proper nutrition to support healing
- Stay consistent with icing and swelling management
- Communicate openly with your care team about pain or concerns
When to Expect Full Recovery
Most people return to normal daily activities within three to six months, while athletes may need nine months or longer to resume competitive sports safely.
