Two patients walk in with "meniscus surgery." One was on crutches for six weeks. The other was back at the gym in fourteen days. Same body part, completely different surgeries. The first step in your rehab is knowing which one you had.
Repair vs meniscectomy: what's the difference
The meniscus is a wedge of cartilage that sits between your thigh bone and shin bone. There are two in each knee, one on the inside, one on the outside. They cushion load and help the knee track properly.
A meniscus repair stitches the torn cartilage back together. The body then heals the tear over months. Because cartilage has poor blood supply, the rehab has to protect the repair while it knits. That means restricted weight-bearing and limited knee flexion for six weeks.
A meniscectomy trims the torn piece out. There's nothing to protect because nothing was repaired. You can put weight through the leg immediately. Most patients walk out of hospital without crutches the same day.
The surgical decision usually comes down to where the tear is. Tears in the outer third of the meniscus get blood supply and can heal, so they're repaired. Tears in the inner two-thirds can't heal, so they get trimmed.
Recovery after a meniscectomy
- Week 0 to 2: Swelling control, full range of motion, quad activation. Walking without crutches within the first week.
- Week 2 to 4: Stationary bike, leg press, light squats, balance work. Most desk workers are back at work by week one.
- Week 4 to 8: Running on the treadmill, change of direction drills, plyometric progressions.
- Week 8 to 12: Return to sport for most people who do the work.
The catch with meniscectomy is what happens five and ten years later. Removing meniscus tissue increases the load going through your cartilage, which raises your risk of knee osteoarthritis. Strength work isn't optional for these patients. It's a long-term insurance policy.
Recovery after a meniscus repair
- Week 0 to 2: Brace locked in extension, partial weight bearing with crutches, quad activation, gentle range of motion to 90 degrees.
- Week 2 to 6: Brace unlocked progressively, range of motion increased to 120 degrees by week six. Still no deep squatting.
- Week 6 to 12: Off crutches, normal walking gait, full range of motion, light strengthening, stationary bike.
- Month 3 to 5: Full strengthening, deep squats reintroduced, light running.
- Month 5 to 6: Return to sport with clearance.
Re-tear rates for repaired menisci sit around 10 to 25 percent. Most re-tears happen in the first six months when patients ignore the loading restrictions. Don't deep squat too early. Don't twist on a planted foot. Don't run before you're cleared.
The hardest part of a meniscus repair isn't the pain. It's the boredom. Six weeks of protected movement when the knee already feels okay. That patience is what determines whether the repair holds.
What if you had a degenerative tear
If you're over 50 and your tear was found on an MRI without major trauma, it's likely a degenerative tear. Strong evidence now suggests these don't need surgery. Twelve weeks of structured physio gets the same outcome as arthroscopy for most degenerative meniscus tears. If you've had one done already, the rehab is identical to a meniscectomy.
What to bring to your first appointment
Your surgical report. It tells us exactly what was done, where the tear was, and what restrictions your surgeon set. Bring your MRI report too if you have it. Book a 60-minute first session. We'll go through your timeline and build a plan you can actually follow alongside work or training.
