Posterior cruciate ligament (PCL) and posterolateral corner (PLC) injuries are relatively uncommon, occurring less frequently than anterior cruciate ligament injuries. Because of this, they may go undiagnosed. And when they are diagnosed, surgical repair can be complex and involve multiple ligaments.

For ICJR Mobile, the app for smart phones and tablets from the International Congress for Joint Reconstruction, Michael B. Banffy, MD, has developed a new featured collection, PCL/PLC Reconstruction, that explores the mechanisms of injury, diagnosis, and treatment options for these injuries. Dr. Banffy is from the Kerlan-Jobe Orthopaedic Clinic in Los Angeles, California.

Videos in Dr. Banffy's collection include:

• PCL Injuries: Treatment Options, by Richard D. Parker, MD
• Single Bundle Posterior Cruciate Ligament Reconstruction - Surgical Technique, by Stephen G. Silver, MD
• Posterolateral Reconstruction of the Knee, by Paolo Adravanti, MD
• Posterolateral Corner Injury, by Stephen G. Silver, MD

In addition, Leesa Galatz, MD, from Washington University in St. Louis, Missouri, has put together a featured collection focused on Total Shoulder Arthroplasty.

More than 50,000 people undergo total shoulder arthroplasty in the U.S. annually. Like total knee and total hip replacement, shoulder replacement is effective in providing pain relief and improving function in patients with osteoarthritis. In the videos in this collection, experienced shoulder surgeons review technical aspects of the procedure, including how to obtain good exposure and component orientation.
