PRP may help certain meniscal tears, particularly degenerative tears, by supporting the knee’s healing environment — though suitability depends on the type and pattern of the tear.
A meniscal tear is one of the most common knee injuries seen in orthopaedic practice. It affects athletes who sustain an acute twisting injury. It also affects older adults who develop degenerative tears through normal wear and tear. The question most patients want answered is: do I need surgery? In many cases, the answer is no — and understanding your options is the first step.
This guide is for people with a meniscal tear in Sydney’s north-west and the Southern Highlands. It offers clear, balanced information about the treatment landscape, including newer regenerative approaches.
What Is the Meniscus?
Each knee has two menisci — the medial meniscus (inner side) and the lateral meniscus (outer side). These are C-shaped wedges of fibrocartilage that sit between the femur (thigh bone) and tibia (shin bone). They serve several critical functions: distributing load across the knee joint, acting as shock absorbers, providing stability, and assisting with joint lubrication.
The menisci have a limited blood supply — only the outer third (the “red zone”) is well vascularised and capable of healing. Tears in the inner two-thirds (the “white zone”) have no blood supply and very limited natural healing potential.
Types of Meniscal Tear
- Acute traumatic tears — typically occur in younger patients from a sudden twisting or pivoting injury, often in sport. Common tear patterns include bucket-handle tears and radial tears
- Degenerative tears — occur in middle-aged and older patients as the meniscus becomes stiffer and more brittle with age. Often develop gradually and may be associated with osteoarthritis
- Horizontal cleavage tears — run horizontally through the middle of the meniscus and are common in middle-aged patients
Symptoms
- Pain along the inner or outer joint line of the knee
- Swelling, particularly in the hours following an acute injury
- Stiffness and limited range of motion
- A catching, locking, or clicking sensation in the knee
- In acute bucket-handle tears: the knee may become “locked” and unable to straighten
- Giving way or instability
Do All Meniscal Tears Need Surgery?
No — and this is one of the most important messages for patients to understand. A substantial body of research over the past decade has challenged the idea that meniscal tears routinely require surgical intervention.
Degenerative meniscal tears in middle-aged patients represent the majority seen in clinical practice. For these tears, multiple high-quality randomised controlled trials have compared physiotherapy-based rehabilitation with arthroscopic partial meniscectomy. Rehabilitation produces equivalent outcomes with fewer risks. The Lancet and NEJM have both published landmark studies supporting this finding.
Surgery is still appropriate in specific circumstances. These include locked knees from bucket-handle tears, unstable tears in younger patients, and repairable tears in the vascular zone. It is not, however, the default answer for all meniscal tears.
Conventional Non-Surgical Treatment
- Physiotherapy — the cornerstone of non-surgical management, focusing on quadriceps and hip strengthening, movement pattern correction, and gradual return to activity
- Activity modification — reducing high-impact and twisting activities during the acute phase
- NSAIDs — for pain and swelling management
- Corticosteroid injection — can reduce intra-articular inflammation, particularly in degenerative tears associated with early arthritis
The Role of PRP in Meniscal Tear Management
PRP therapy is an emerging option for meniscal tear management. It suits patients who have persistent pain and swelling despite physiotherapy, and who want to avoid or delay surgery. The rationale is compelling. The growth factors in PRP — including PDGF, TGF-β, and FGF — can stimulate the repair of cartilage and fibrocartilage tissue. They also reduce joint inflammation and support the biological environment within the knee.
PRP is most likely to be beneficial in:
- Partial tears or degenerative tears where the patient is trying to avoid surgery
- Tears in the vascular zone that may respond to biological stimulation
- Knees with associated early osteoarthritis, where PRP can address multiple pathologies simultaneously
PRP is not a solution for mechanically unstable tears (such as large bucket-handle tears causing locking) or for tears requiring direct surgical repair in elite athletes. In these situations, surgery remains the appropriate choice.
Get the Right Advice for Your Knee in Sydney’s North-West or the Southern Highlands
Meniscal tear management is nuanced and should be tailored to the individual. The type of tear, the patient’s age and activity level, the presence of knee arthritis, and their goals all influence the best approach.
At Dr John PRP, we provide thorough assessment and evidence-based guidance for patients with meniscal tears across Sydney’s north-west — including Castle Hill, Norwest, Kellyville, and Baulkham Hills — and the Southern Highlands, including Bowral and Mittagong.

Frequently Asked Questions
Can PRP treat a meniscal tear?
PRP may help certain meniscal problems, particularly degenerative tears and associated inflammation, by supporting the knee’s healing environment. It is best suited to specific tear types, and suitability is confirmed after reviewing your imaging and symptoms.
Is PRP an alternative to knee surgery for a meniscus tear?
For some patients, PRP offers a non-surgical option to trial before considering surgery, especially for degenerative tears. Acute or mechanically unstable tears may still require surgical assessment. We help you understand which pathway suits your situation.
How many PRP injections are needed?
Most patients require a course of 2 to 3 PRP injections spaced several weeks apart, though the exact number depends on the nature of the tear and your response. Your treatment plan is tailored following assessment.
Do I need a referral to be assessed?
Not usually. If you already have imaging and a diagnosis you can often book directly. For more complex cases we may recommend consulting your GP first. We see patients across Sydney’s North-West and the Southern Highlands.
