Combined anterior cruciate ligament reconstruction and unicompartmental knee arthroplasty: surgical technique.

Anterior cruciate ligament (ACL) reconstruction can be safely combined with medial unicompartmental knee arthroplasty from a technical point of view. The procedure has been performed in younger patients with the goal of preserving bone in case of need for future revision. The short-term results are encouraging although longer-term data are necessary to thoroughly evaluate the role of this procedure in patients with medial compartment osteoarthritis and ACL deficiency.
