ACL Tear Treatment in Irvine, Riverside and Orange County:
Tearing the anterior cruciate ligament (ACL) is one of the most common and serious knee injuries, especially among athletes and active individuals across all levels of competition. The ACL is a crucial ligament that stabilizes the knee joint, allowing for cutting, pivoting, and sudden directional changes. When an ACL tear occurs, the tibia (shin bone) can slide forward beyond its normal position under the femur (thigh bone), resulting in joint instability, pain, and limited mobility.
Left untreated, an ACL tear can lead to long-term damage, including cartilage and meniscus injuries, and increase the risk of early-onset osteoarthritis. Dr. Prem N. Ramkumar is a board-certified orthopedic knee specialist based in Long Beach, California, providing expert ACL tear diagnosis and treatment for patients throughout Irvine, Riverside and Orange County.

What is a meniscus tear?
A meniscus tear can range from mild to severe and may involve partial detachment, circumferential tearing, or unstable fragments within the knee joint. Contrary to common belief, most meniscus surgeries involve removing the damaged portion rather than repairing it. Meniscus repair is most successful in younger patients and specific tear patterns that promote natural healing. If the tear fails to heal, a second surgery may be needed—making accurate diagnosis and expert treatment planning critical.
