What should I do if my medial knee ligament injury prevents full extension?

Patients with medial collateral ligament (MCL) injury of the knee who cannot fully extend the knee can generally undergo symptomatic treatment under a physician’s guidance—such as using appropriate traditional Chinese medicines that promote blood circulation and relax tendons and muscles. Rehabilitation exercises may also serve as adjunctive therapy. Additionally, treatments such as massage and acupuncture can provide certain therapeutic benefits. In daily life, patients should avoid engaging in overly strenuous physical activities.
