Meniscal root repair — rehabilitation protocol
Protecting the reattachment takes priority over an early return to walking and squatting. Motion is restored gradually, and loading progresses after review of healing and knee tolerance.
Using and loading the limb
The described conservative pathway uses 6 weeks without weight bearing, followed by gradual cleared progression, usually over another 2–4 weeks.
Full guidance ↓Brace or immobilisation
Brace and walking lock follow surgical instructions. Weaning crutches requires safe gait without limping or reactive effusion.
Full guidance ↓Permitted movement
During protection, passive/assisted flexion to 90° and gentle full extension. Defer deep loaded flexion, jumping and twisting according to the stages.
Full guidance ↓Permitted movement, loading and removal of a brace are separate decisions. Additional repairs may require a more protective programme.
Rehabilitation at a glance
Progression follows healing and functional criteria, not dates alone.
Rehabilitation boards
Exercises — a closer look
Use the complete boards above together with the instructions for the chosen stage. An exercise shown for a later stage is not permitted early.
Open the relevant complete board and zoom in. The viewer retains all stages and captions.
5. How to perform the exercises
- 1. Ankle pumps: move the foot up and down with the knee supported; 10–20 repetitions in short bouts during the day.
- 2. Quadriceps set: tighten the front of the thigh without lifting the knee; hold 5 seconds, repeat 8–10 times. Breathe normally.
- 3. Assisted flexion: the therapist supports and guides the limb within the prescribed range; 5–10 slow repetitions without actively pulling the heel in.
- 4. Shallow squat: only in the loading phase; both feet flat, hands on a stable support and knees aligned over the feet. Start with 1 set of 8 repetitions.
The illustrations show technique, not the permitted angle or start date. Exercise 4 belongs to the stage after weight bearing is authorised. The doses are suggested starting points for individual adjustment, not findings from dose-comparison trials.
Scope and protection
1. Repair protection and operative information
Confirm the root, fixation technique, tissue quality, associated repairs and motion limits. This protective pathway uses 6 weeks without weight bearing on the operated limb and passive or assisted flexion up to 90° during that period. Restore full extension without force. Brace use and locking during transfers follow the orthopaedic surgeon’s instructions; absence of pain does not authorise earlier loading.
Stages and progression criteria
2. Weeks 0–6 — healing and controlled motion
- Use two crutches, learn safe transfers and prevent falls. Do not put body weight through the flexed knee.
- Ankle movements and gentle quadriceps and hip activation. Straight leg raising only without an extension lag and as instructed.
- Bend the knee with the limb supported; avoid pulling the heel in with a strong hamstring contraction. No squats, kneeling, pivoting or resisted knee flexion.

3. Weeks 6–12 — progressive weight bearing
After review and surgical clearance, increase weight bearing gradually, usually over the next 2–4 weeks. Wean from crutches only with a non-limping gait and no reactive effusion. Progress flexion beyond 90° without forcing it. Add an unloaded stationary bicycle when motion permits a complete revolution.
Once loading is authorised: shallow squats, initially to about 30°, weight shifts and supported balance. Do not increase squat depth and resistance at the same time.
4. From week 12 — strength and activity
Develop single-leg control, hip strength and quadriceps strength. Defer deep loaded squats, jumping and pivoting for at least 4 months; thereafter they require clearance and good tolerance. After medial root repair, introduce resisted knee flexion cautiously, usually around month 4.
Consider running no earlier than about month 6, after brisk walking is tolerated and motion, control and strength are restored. Pivoting sport usually requires 6–9 months or longer. A practical target before full sport is no effusion, at least 90% side-to-side strength and functional test performance, and good movement quality; symmetry alone is insufficient.
Daily activities and follow-up
Progress in everyday activities follows the permitted loading and motion for your procedure. Walking without aids requires a controlled gait; returning to driving requires safe vehicle control and no impairing medication. The detailed recommendations below explain the criteria and exceptions.
6. Daily activities and follow-up
Practise crutch walking and stairs with a physiotherapist while respecting the prescribed weight-bearing limit. Use a handrail and assistance until walking is safe. Avoid turning on the planted operated foot; change direction with small steps.
Take position-change breaks during desk work. Resume driving only when you can safely perform an emergency stop, without a restrictive brace or medication impairing performance. Wound review is usually around days 10–14; later reviews follow the surgeon’s schedule. Follow the discharge instructions for medication and thromboprophylaxis.
Warning signs
7. Pain, swelling and warning signs
Assess the knee the next day as well as immediately after exercise. Increased effusion, limping or worsening pain calls for a lower dose and reassessment. Rest with the limb elevated and brief cooling through a cloth may ease symptoms; protect the skin and wound.
Urgent medical review: fever, wound discharge or opening, increasing redness, calf pain and swelling, new knee locking or sudden loss of extension. Do not massage a painful swollen calf.
Emergency help — call 112 or your local emergency number: breathlessness, chest pain, fainting, a cold or pale foot, or rapidly worsening severe pain with altered sensation.

Clinical commentary and terms of use
8. Protocol commentary
No single best root rehabilitation schedule has been established. These restrictions are a protective synthesis of consensus and literature, not a universal rule for every technique. Repair does not remove pre-existing osteoarthritis; the activity goal also depends on cartilage and limb alignment. The functional thresholds are practical clinical criteria, not a validated test of root healing.
