ACL Sprains
Partial ACL tears can cause knee pain and instability without complete rupture of the ligament. PRP (Platelet-Rich Plasma), often combined with Hyaluronic Acid (HA), is injected into the knee joint, typically 5-10 days after injury. It aims to reduce inflammation, which may lead to less pain.
PRP is considered for partial tears with Grade 1-2 laxity and, for some patients, may help to avoid surgery. Treatment is combined with bracing where needed and a strict neuromuscular rehabilitation program, which is essential to the outcome. Complete ACL tears generally require surgical assessment. Results vary between individuals and suitability is assessed at consultation. Dr John sees patients in Bowral, serving the Southern Highlands, and at Norwest Private Hospital in Bella Vista.

Frequently Asked Questions
What is an ACL Sprain, and how is PRP thought to help in its treatment?
An Anterior Cruciate Ligament (ACL) sprain refers to an injury to the ACL, one of the key ligaments in the knee that provides stability. ACL sprains are graded from 1 (mild stretch) to 3 (complete tear). Platelet-Rich Plasma (PRP) involves injecting a concentrated solution of your own blood platelets, rich in growth factors, directly into the injured ACL. For partial ACL tears, PRP aims to reduce inflammation in the knee, which may lead to less pain. In carefully selected cases it may help to avoid or delay surgery.
Am I a suitable candidate for PRP treatment for an ACL Sprain in Australia?
Suitability for PRP treatment for an ACL sprain depends significantly on the grade of the sprain and other factors. PRP is most commonly considered for partial ACL tears (Grade I or II) where some fibres of the ligament remain intact. It is generally not the primary treatment for complete (Grade III) ACL tears, which often require surgical reconstruction, though some research explores its use as an adjunct to surgery. Your doctor will conduct a thorough assessment to accurately diagnose the grade of your ACL sprain and assess the overall stability of your knee. They will discuss the potential benefits and limitations of PRP in your specific case, weighing it against other treatment options like physiotherapy or surgery.
What does a PRP injection for an ACL Sprain involve, and what's the typical recovery process like?
The procedure for a PRP injection for an ACL sprain typically involves drawing a small amount of blood from your arm. This blood is then processed in a centrifuge to separate and concentrate the platelets, creating the PRP solution. The concentrated PRP is then precisely injected into the injured ACL within the knee joint. You might experience some mild discomfort during and immediately after the injection. Post-injection, it’s common to have some temporary soreness, swelling, or stiffness in the knee for a few days. Your doctor will provide specific post-injection instructions, which usually involve a period of protected weight-bearing and reduced activity, followed by a very structured and intensive rehabilitation program, often with a physiotherapist. The recovery for an ACL sprain, even with PRP, is a lengthy process, typically taking several months (e.g., 6-12 months).
How many PRP injections are usually needed for an ACL Sprain, and is it covered by Medicare or private health insurance in Australia?
The number of PRP injections needed for an ACL sprain can vary. While some protocols might involve a single injection, others may recommend a series of 2 to 3 injections, typically spaced a few weeks apart, especially for more significant partial tears or as part of a comprehensive non-surgical management plan. Your doctor will advise on the most appropriate number of injections for your specific ACL injury. In Australia, PRP treatments for ACL sprains (both for partial tears and as an adjunct to surgery) are generally not covered by Medicare. This means the cost of the PRP procedure itself is typically an out-of-pocket expense for the patient. Similarly, most private health insurance funds in Australia currently do not provide rebates for PRP therapy. It is always advisable to discuss the full costs involved and confirm any potential out-of-pocket expenses directly with your clinic and your private health fund prior to commencing treatment.
