Meniscus Repair vs. Meniscectomy: Differentiated Rehabilitation

Rehabilitation following meniscus surgery differs greatly depending on whether the procedure was a repair (preserving tissue) or a meniscectomy (removing tissue). The primary difference lies in tissue healing timelines, weight-bearing precautions, and exercise progression.

Meniscus Repair Rehabilitation

Rationale

The meniscus is preserved, requiring biological healing.
Rehab must protect the sutured meniscus while promoting mobility and strength.

Phase I: Protection (0–6 weeks)

Weight-bearing: Typically partial, often with crutches.
ROM limits: Flexion restricted to 90° initially.
Exercises: Quadriceps sets, straight leg raises, ankle pumps, hip abduction/adduction (supine).

Phase II: Controlled Motion (6–12 weeks)

Weight-bearing: Progress to full.
ROM: Gradual restoration toward full flexion.
Exercises: Closed-chain strengthening (mini-squats, leg press 0–60°), balance work.

Phase III: Strength & Endurance (3–5 months)

Strengthening: Progressive resistance, proprioceptive drills.
Cardio: Cycling, elliptical.
Functional drills: Step-ups, lunges.

Phase IV: Return to Sport (6+ months)

Plyometrics, agility, and sport-specific training.
Running typically delayed until 5–6 months post-op.

Meniscectomy Rehabilitation

Rationale

Tissue is excised; no biological healing required.
Rehab is focused on pain control, swelling reduction, and early restoration of function.

Phase I: Immediate Motion (0–2 weeks)

Weight-bearing: As tolerated, often same-day or next-day.
ROM: No restrictions.
Exercises: Quad activation, heel slides, cycling without resistance.

Phase II: Strength & Endurance (2–4 weeks)

Strengthening: Closed-chain and open-chain within tolerance.
Cardio: Stationary bike, pool therapy.

Phase III: Advanced Strength (4–6 weeks)

Exercises: Squats, leg press, hamstring curls, proprioceptive training.
Return to function: Many resume sports or full activity within 6–8 weeks.

Key Differences in Protocols

Repair = slower progression to protect healing tissue.
Meniscectomy = rapid progression, as there is no repair to safeguard.
Return to sport: 6–8 weeks for meniscectomy vs. 6+ months for repair.
Precautions: Flexion and weight-bearing limited in repairs, unrestricted in meniscectomies.

Clinical Considerations

Age, tear location, and vascularity affect healing after repair.
Overly aggressive rehab post-repair risks re-tear.
Meniscectomy allows faster return but increases long-term risk of osteoarthritis.

✅ Conclusion

Meniscus repair: Prioritises tissue healing, slower but protective.
Meniscectomy: Faster recovery, but long-term risks.
Rehab should always be individualised based on surgical findings, patient goals, and functional demands.
