Arthroscopic Meniscus Repair

Phase I (Weeks 0-6)

1. Weightbearing: As tolerated with crutches
2. Hinged Knee Brace
   • Worn for 4 weeks post-op
   • Locked in full extension for ambulation and sleeping – remove for hygiene and PT (Weeks 0–2)
   • Unlocked for ambulation and removed while sleeping, for hygiene and PT (Weeks 2–4)
3. Range of Motion – AAROM → AROM as tolerated
   • Weeks 0–4: Full ROM – no weightbearing at flexion angles greater than 90°
   • Weeks 4–6: Full ROM as tolerated – progress to flexion angles greater than 90°
4. Therapeutic Exercises
   • Quad / Hamstring sets, heel slides, straight leg raises, co-contractions
   • Isometric abduction and adduction exercises
   • Patellar mobilizations
   • At 4 weeks: Begin partial wall-sits – keep knee flexion angle less than 90°

Phase II (Weeks 6-12)

1. Weightbearing: As tolerated — discontinue crutch use at 6 weeks
2. Hinged Knee Brace: Discontinue brace use when patient has achieved full extension with no evidence of extension lag
3. Range of Motion – Full active ROM
4. Therapeutic Exercises
   • Closed-chain extension exercises, hamstring strengthening
   • Lunges – 0–90°, leg press – 0–90°
   • Proprioception exercises
   • Begin use of the stationary bicycle

Phase III (Weeks 12-16)

1. Weightbearing: Full weightbearing with normal gait pattern
2. Range of Motion – Full / painless ROM
3. Therapeutic Exercises
   • Continue with quad and hamstring strengthening
   • Focus on single-leg strength
   • Begin jogging / running
   • Plyometrics and sport-specific drills

Phase IV (Months 4-6)

1. Gradual return to athletic activity as tolerated
2. Maintenance program for strength and endurance
