BACKGROUND The effectiveness of anterior cruciate ligament reconstruction for restoring normal knee kinematics is largely unknown, particularly during sports movements generating large, rapidly applied forces. HYPOTHESIS Under dynamic in vivo loading, significant differences in 3-dimensional kinematics exist between anterior cruciate ligament-reconstructed knees and the contralateral, uninjur...

The structures in the posterolateral corner of the knee, which stabilize the joint, are often involved in injuries to the posterior cruciate ligament. Familiar structures include the anterior cruciate ligament, posterior cruciate ligament, tibial collateral ligament, and menisci. Less familiar are the structures of the posterolateral corner, the most important of which are the fibular collatera...

BACKGROUND Evidence regarding the risk of end-stage osteoarthritis following cruciate ligament reconstruction is based upon small sample sizes and radiographic, rather than clinical, criteria. The goals of this study were to determine the risk of knee arthroplasty, a surrogate for end-stage osteoarthritis, following cruciate ligament reconstruction, and to identify patient, provider, and surgic...

With most posterior cruciate (PCL) reconstruction techniques, the distal end of the graft is fixed within a tibial bone tunnel. Although a surgical goal is to locate this tunnel at the center of the PCL's tibial footprint, errors in medial-lateral tunnel placement of the tibial drill guide are possible because the position of the tip of the guide relative to the PCL's tibial footprint can be di...

One should suspect a compromise of the lateral structures when presented with a posterior cruciate ligament (PCL) injury, especially if grade III laxity is present. In our experience, if a combined injury to the PCL and posterolateral corner is diagnosed, a combined PCL and posterolateral reconstruction is needed to restore stability. This article describes a posterolateral reconstruction proce...

OBJECTIVE The objective of this study was to evaluate the results obtained from posterior cruciate ligament (PCL) reconstruction with the double femoral tunnel technique, using quadriceps tendon and semitendinous autograft, in patients with isolated PCL tears or PCL tears associated with other ligament lesions, 2 years after surgery. METHODS The study included 14 patients with isolated PCL le...

The association of an anterior cruciate ligament (ACL) tear and a posterior cruciate ligament (PCL) injury is rare in athletes, and to our knowledge it has never been described in a professional rugby player. We report the case of a 27-year-old international professional rugby player who presented with an ACL tear associated with chronic posterior laxity on a former PCL tear. The procedure asso...

BACKGROUND We compared the efficacy of combined posterior lumbar plexus-sciatic nerve block with that of combined femoral-obturator-sciatic nerve block as anesthesia for anterior cruciate ligament reconstruction surgery, because both block combinations have been recommended for lower limb arthroscopic and reconstructive surgery. METHODS Forty-eight patients undergoing elective unilateral ante...

During daily training, shot putters are prone to acute complete anterior cruciate ligament injury, which is mainly treated with early reconstruction under knee arthroscopy to restore stability of injured athletes’ knee as soon as possible, help them towards early recovery and resume normal work and training. During knee arthroscopic treatment, extrusion screws are mainly used for acute complete...
