Knee ligament repair or reconstruction is a treatment for a complete tear of a knee ligament that results in instability in the knee. People with a torn knee ligament may be unable to do normal activities that involve twisting or turning at the knee. The knee may buckle or “give-way.” If medical treatments are not satisfactory, ligament repair or reconstruction surgery may be an effective treatment.
The surgery to correct a torn knee ligament involves replacing the ligament with a piece of healthy tendon. A tendon from the kneecap or hamstring, for example, is grafted into place to hold the knee joint together. The tendon graft may come from the person (autograft) or from an organ donor (allograft).
There may be other reasons for your doctor to recommend a knee ligament repair or reconstruction.
