MCL Sprains
Medial collateral ligament (MCL) sprains cause medial knee pain and valgus instability. PRP therapy enhances healing in Grade 1-2 injuries by delivering concentrated platelets to the damaged ligament fibres. The growth factors in PRP promote organised collagen deposition, reducing scar tissue formation. The injection is performed under ultrasound guidance 5-7 days post-injury when acute swelling has subsided. Patients follow a structured rehabilitation protocol emphasising early protected motion and progressive resistance training.
PRP-treated MCL sprains typically heal with better tissue quality and less residual laxity compared to natural healing. The treatment is particularly valuable for athletes wanting to return to sport faster with reduced reinjury risk. Unlike surgery required for complete tears, PRP offers a minimally invasive option for partial injuries.

Frequently Asked Questions
What is an MCL Sprain, and does PRP assist healing?
An MCL (Medial Collateral Ligament) sprain is an injury to the ligament on the inner side of the knee, which helps stabilise the joint against outward forces. MCL sprains are graded from 1 (mild stretch) to 3 (complete tear). Unlike the ACL, the MCL generally has a better capacity for natural healing due to its blood supply. Platelet-Rich Plasma (PRP) involves injecting a concentrated solution of your own blood platelets, rich in various growth factors, directly into the injured MCL. The aim is for these concentrated growth factors to enhance the body’s natural healing and repair mechanisms, promote the regeneration of ligament fibres, reduce inflammation, alleviate pain, and potentially accelerate recovery and improve the structural integrity of the damaged ligament.
Am I a suitable candidate for PRP treatment for an MCL Sprain in Australia?
PRP treatment for an MCL sprain is typically considered for individuals with Grade II or III MCL sprains that are not progressing as expected with conservative management, or for those seeking to potentially accelerate their recovery. While many MCL sprains heal well with physiotherapy and bracing alone, PRP might be an option if healing is slow, or in cases of chronic pain. Your doctor will conduct a thorough assessment, including a physical examination and often an MRI scan, to accurately diagnose the grade of your MCL sprain and assess the overall stability of your knee. They will discuss the potential benefits and limitations of PRP in your specific situation, especially considering the MCL’s natural healing capacity.
What does a PRP injection for an MCL Sprain involve, and what's the typical recovery process like?
The procedure for a PRP injection for an MCL sprain typically begins with drawing a small amount of blood from your arm. This blood is then processed in a specialised centrifuge to separate and concentrate the platelets, creating the PRP solution. The concentrated PRP is then precisely injected into the injured MCL, usually guided by ultrasound to ensure accurate placement. You might experience some mild discomfort or a feeling of pressure during the injection. After the procedure, it’s common to have some localised soreness, swelling, or bruising on the inner side of the knee for a few days. Your doctor will provide specific post-injection instructions, which usually involve a period of reduced activity and protection, followed by a gradual and structured rehabilitation program. The recovery timeline for an MCL sprain, even with PRP, varies depending on the grade of the injury, but typically involves several weeks to a few months for full return to activity.
How many PRP injections are usually needed for an MCL Sprain, and is it covered by Medicare or private health insurance in Australia?
The number of PRP injections needed for an MCL sprain can vary depending on the individual’s response and the severity of the injury. Often, a single injection might be performed, but in some cases, a course of 1 to 2 injections spaced a few weeks apart may be recommended to achieve optimal results, particularly for higher-grade sprains. Your treating specialist will advise on the most appropriate number of injections for your specific MCL injury. In Australia, PRP treatments for MCL sprains 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 for MCL injuries. 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.
