Meniscal Tears

Suitability for PRP treatment for a meniscal tear depends on several factors, including the type, location, and size of the tear, as well as your overall health and activity level. Tears in the outer, well-vascularised (red zone) part of the meniscus generally respond better to conservative treatment, including PRP, compared to tears in the inner, avascular (white zone) part. Your doctor will typically assess your tear using an MRI scan and discuss your symptoms. PRP is usually considered for smaller, stable tears or as an adjunct to surgery in some cases, rather than for large, unstable tears that may require surgical intervention. It’s often explored after conservative measures like rest and physical therapy have not provided sufficient relief.

The procedure for a PRP injection for a meniscal tear is similar to other PRP treatments: blood is drawn from your arm, processed to concentrate the platelets, and then the PRP is precisely injected into the affected area of the meniscus, often guided by ultrasound or fluoroscopy to ensure accuracy. You might experience some temporary discomfort during and immediately after the injection. Post-injection, it’s common to have some localised soreness, swelling, or stiffness in the knee for a few days. Your doctor will provide specific post-treatment instructions, which typically involve a period of reduced weight-bearing and activity, followed by a structured rehabilitation program, often with a physiotherapist. The recovery period varies greatly depending on the individual, the tear, and whether the PRP was used alone or in conjunction with surgery. Full recovery and noticeable improvement can take several weeks to many months, as improvement is gradual.

In Australia, PRP treatments for meniscal tears are generally not covered by Medicare. This means that the cost of the procedure is typically an out-of-pocket expense for the patient. Similarly, most private health insurance funds in Australia currently do not provide coverage for PRP therapy when used for meniscal tears, as it is still considered an emerging treatment with ongoing research regarding its long-term efficacy and standardisation. The number of PRP injections required can vary, but commonly, a single injection is performed, though some protocols might involve two or more injections spaced a few weeks apart, depending on the tear and the individual’s response. It’s always advisable to discuss the estimated costs and expected number of injections directly with your doctor and to confirm your coverage (or lack thereof) with your private health insurer before proceeding with treatment.
