The knee joint contains two C-shaped wedges of cartilage called the menisci. When one tears, it disrupts the cushioning that protects the joint during every step, pivot, and landing. Surgery offers an intervention for tears, but another solution involves a platelet-rich plasma (PRP) therapy. At Regenerative Medicine and Orthopedics, our sports injury doctor provides a non-surgical treatment that uses the body’s own biology to drive healing. Here’s why athletes are choosing PRP for meniscal tears:
Meniscal Tears and the Knee
The menisci distribute the body’s weight across the knee joint. When a tear occurs, that load distribution becomes compromised. It causes localized pain, swelling, stiffness, and reduced range of motion. Certain movements, such as rotation and deep flexion, become difficult to maintain.
Because the meniscus has a limited blood supply in its inner portions, tears in those areas can struggle to heal. Treatment options for tears in the outer zone are more responsive to regenerative approaches, while those deeper in the cartilage present a greater challenge. A thorough medical evaluation with imaging helps determine which type of tear is present and whether a patient needs non-surgical treatments. A sports injury doctor helps determine the type of approach that helps the patient heal properly.
PRP Treatments and Options
Platelets are blood cell fragments loaded with growth factors. The body naturally sends platelets to the site to initiate tissue repair when injuries occur. PRP therapy concentrates those platelets by drawing blood from the patient, processing it to remove red blood cells and other components, and injecting the resulting plasma. This helps with healing when it’s injected into the damaged tissue.
When injected into an injured knee, PRP stimulates new collagen production. That process results in healthier, stronger tissue, reduced pain, and improved function. The mechanism is not masking symptoms; it is actively promoting structural repair at the injury site.
Platelet concentration varies depending on the system used. Some protocols draw only 10–30 ml of blood and concentrate platelets just 2–5 times above baseline; this often requires multiple injection sessions. Higher-dose protocols can achieve platelet concentrations 25–30 times above baseline, with total platelet counts in the range of 12–24 billion per dose. Research supports the principle that higher platelet counts produce better outcomes for orthopedic conditions, and higher-dose approaches are associated with achieving results in a single treatment rather than a series.
PRP Injections and Surgery
Surgical intervention for meniscal tears involves repair or partial removal of the damaged cartilage. PRP is an office-based procedure. It does not require general anesthesia, hospital admission, or the extended post-operative rehabilitation that surgery demands. Athletes can begin a structured recovery protocol relatively quickly after treatment, and the goal of that recovery is to restore function.

Meniscal tears have different treatment options, including surgery and PRP injections. PRP offers a biologically grounded, non-surgical path to knee recovery; a doctor uses the body’s own repair mechanisms. The variables involve platelet concentration, injection precision, and a comprehensive recovery plan.
