Posterior Cruciate-Retaining Total Knee Arthroplasty
Richard Scott, MD
Professor of Orthopaedic Surgery, Emeritus

Abstract: Total knee arthroplasty has evolved into a very successful procedure to relieve pain and restore function in the arthritic knee with advanced structural damage. Optimal results are dependent on the restoration of alignment and ligament stability. Operative techniques involve either preservation of the posterior cruciate ligament or substitution of its function through increased prosthetic constraint. The vast majority of knees do not require cruciate substitution to establish appropriate stability and function. This video outlines the operative technique used by the author for posterior cruciate-retaining total knee arthroplasty in a patient with a preoperative varus deformity.

Dr. Li addresses an ACL torn after a pivot shift incident using a BTB autograft. The anteromedial approach to ACL reconstruction offers the advantage of reliably reproducing the native anatomy of the ACL on the femur footprint by drilling the femoral tunnel independently of the tibial tunnel.
JoMI has just published a new video article by Dr. Matthew Provencher, Chief of Sports Medicine at the Massachusetts General Hospital and Medical Director of the New England Patriots.
The video article covers in detail a procedure to resurface the cartilage of the knee for a patient with a condition called Osteochondritis Dissecans (OCD).
