Post operative phase | Rehabilitation regimen |
---|---|
Phase 1. Duration 2–4 weeks | Immediate straight leg raising. Early range of motion exercise with an emphasis on gaining full knee extension (0°). Weight bearing full as tolerated. First week 70° of flexion. Static squat (90° flexion) |
Phase 2. Duration 2–3 months | Endurance training (biking). Progressive resistance training (leg press, calf press, step up). Dynamic squat (0°–110°). Balance exercises. Eccentric muscle contractions. Progressive resistance exercise full range of motion, hop on one leg without pain. Isokinetic exercise and assessment. |
Phase 3. Duration 3–6 months | Continued progressive resistance and endurance training. Jogging/running, swimming. Eccentric training (active lengthening force production- such as jumping exercises). Strengthening and functional exercise training to prepare the individual for full return activity. Criteria for returning to full activity: 80% strength and 85% functional ability, proprioception > 90%, extension/flexion strength difference > 70% compared to the non-surgical lower extremity ysholm knee score > 90 |
Functional brace | 6 weeks |
