Arthroscopic anterior cruciate ligament reconstruction: a metaanalysis comparing patellar tendon and hamstring tendon autografts.

Background: The best choice of graft tissue for use in anterior cruciate ligament reconstruction has been the subject of debate.

Hypothesis: Anterior cruciate ligament reconstruction with patellar tendon autograft leads to greater knee stability than reconstruction with hamstring tendon autograft.

Study Design: Metaanalysis.

Anterior cruciate ligament reconstruction with patellar autograft tendon.

There are many techniques, graft choices, and outcome studies evaluating anterior cruciate ligament reconstruction. The current authors specifically look at reconstruction with the patellar tendon from a scientific perspective. Miniopen, endoscopic, and two-incision operative techniques in addition to hamstring versus patellar tendon autograft reconstructions are compared via randomized prospective studies.
