An MRI report saying "meniscal tear" reads like a plumbing problem with an obvious fix. That reading is where a lot of people go wrong, because the same words on a scan describe two rather different situations with two different answers. Here is what private meniscus surgery involves and costs, what the trial evidence says about who benefits, and what recovery looks like on either path.
A traumatic tear happens in a moment. A twist on a planted foot, usually in someone under about forty, often with a pop, immediate swelling within hours, and sometimes a knee that locks or catches. This is a mechanical injury to healthy tissue.
A degenerative tear develops over years as the meniscus dries out and frays, typically in people over forty-five. It often appears on a scan alongside early osteoarthritis, and frequently in knees that have no symptoms at all. Studies of asymptomatic middle-aged adults consistently find meniscal tears on MRI in a substantial minority of people who have never had knee trouble.
That second point is what makes the scan report so misleading. Finding a degenerative tear on a scan does not establish that the tear is what hurts. Our article on whether you need a scan covers this problem across the body.
The ESCAPE trial is the most useful piece of evidence for the degenerative group. It randomised 321 patients aged 45 to 70 with degenerative meniscal tears across nine hospitals in the Netherlands to either arthroscopic partial meniscectomy or sixteen sessions of exercise-based physiotherapy.
At five-year follow-up, there was no clinically meaningful difference between the groups in patient-reported knee function. Physiotherapy remained non-inferior to surgery, both groups improved meaningfully, and the authors concluded that exercise-based physiotherapy should be the preferred first treatment for degenerative meniscal tears.
Traumatic tears in younger knees sit outside that evidence, and so do the specific mechanical presentations described below. For the large middle-aged group with a frayed meniscus and an achy knee, the trial answer is clear enough that most UK surgeons now start with exercise.
Trimming a degenerative meniscus removes tissue that was cushioning the joint, which is why the long-term picture matters as much as the short-term relief.
Private quotes are usually built from the same components, and the headline figure often covers only some of them. Ask which of these are included before you compare two quotes:
That last line is the one that most often falls outside the package, and it is the part that decides the result. Fixed-price packages are common and worth asking for explicitly, along with the policy on what happens if a complication needs a further procedure. Our breakdown of private ACL surgery and rehab costs works through the same structure in more detail.
Keyhole trimming is a day case. Weight-bearing is usually allowed straight away, and the rough shape of recovery is:
A meniscal repair is a slower proposition entirely, often with restricted weight-bearing and limited knee bend for around six weeks while the stitched tissue heals, and a return to pivoting sport around four to six months.
The physiotherapy arm of ESCAPE was sixteen supervised sessions, which is a useful benchmark for what "trying exercise first" should mean. It is a programme, not a leaflet.
The content is progressive strength work for the quadriceps, hamstrings, glutes and calf, plus balance and control work, loaded in a range the knee tolerates and built up over weeks. Swelling and pain guide the pace. Most people notice change somewhere in the second month, which is why courses that stop at four weeks so often conclude that exercise did not work.
Our page on meniscal tears sets out the assessment side, and knee pain going down stairs covers a symptom that frequently travels with these knees.
The belief people arrive with, scan report in hand, is that a torn meniscus is a structural fault that has to be repaired before anything else can help. Ashdown Forest and the paths around Buxted Park produce a steady stream of these knees, usually in people in their fifties who twisted on uneven ground, felt something in the knee, and got an MRI that found a degenerative tear.
What testing separates is whether the knee has a mechanical block or an irritable one. A knee that will not fully straighten, with a hard end feel and a fragment catching, is a different problem from a knee that aches on stairs, swells after a long walk and straightens perfectly well when someone else moves it. The first needs a surgical opinion. The second responds to loading the quadriceps and glutes properly, and the ESCAPE five-year data says it does so about as well as an operation would. Getting that distinction right in the first appointment saves people from a procedure that removes cushioning tissue for a symptom it was never causing.
Our meniscal tear page sets out how the two are told apart.
Can a meniscus tear heal on its own?
The outer third has a blood supply and can heal. The inner portion does not heal, though symptoms from it very often settle as the surrounding muscles take over the load.
How long should I try physiotherapy before considering surgery?
Around three months of genuine progressive loading. The ESCAPE physiotherapy arm was sixteen supervised sessions.
Will surgery stop me getting arthritis?
No. Removing meniscal tissue is associated with a higher risk of later osteoarthritis, which is one reason repair is preferred over trimming when the tear allows it.
Do I need an MRI first?
Only if the result would change the plan. A locking knee justifies one. An achy middle-aged knee that has never had loaded exercise usually does not.
How soon can I drive after keyhole surgery?
Once you can control the car safely and perform an emergency stop without hesitating, typically one to two weeks for a left knee in an automatic and longer for a right knee. Confirm with your surgeon.
