Purpose: Dislocated tibial avulsions of the posterior cruciate ligament (PCL) require surgical intervention. Several arthroscopic strategies are options to fix the fragment and restore posterior laxity, including two types of suspension button devices: adjustable (self-locking) and rigid knotted systems. Our hypothesis was that a rigid knotted button construct has superior biomechanical properties regarding laxity restoration compared with an adjustable system. Read More

Background: Posterior cruciate ligament (PCL) reconstruction is commonly performed to restore joint stability and prevent posterior tibial translation at higher flexion angles. However, persistent knee laxity after reconstruction is often reported.

Purpose: To biomechanically evaluate the effect of independent suture tape (ST) reinforcement on different PCL reconstruction techniques. Read More

Background: Anteromedial portal technique (AMP) using hamstring autograft is a popular technique of arthroscopic ACL reconstruction allowing anatomical placement of femoral. In this technique, a cortical suspensory fixation of graft is used on the femoral side and interference screw fixation on the tibial side using a complete bone tunnel. All-inside translateral technique is a recently introduced technique which uses a closed loop of quadrupled semitendinosus graft with an adjustable cortical suspensory fixation on both sides allowing optimum tensioning of graft and near-complete filling of retrosockets created by the flip cutter on both femoral and tibial sides.

Background: Fractures of the patella (kneecap) account for around 1% of all human fractures. The treatment of these fractures can be surgical or conservative (such as immobilisation with a cast or brace). There are many different surgical and conservative interventions for treating fractures of the patella in adults. Read More

Department of Orthopaedic Surgery, MedStar Union Memorial Hospital, Baltimore, Maryland, USA.

Background: Adjustable cortical fixation devices have demonstrated utility in orthopaedic applications, such as ankle syndesmosis repair.

Purpose: To assess the cyclic gap formation of a quadriceps tendon repair technique using an adjustable cortical fixation device compared with repair with knotless suture anchors and suture tape, a modification of conventional suture anchor repair.

Study Design: Controlled laboratory study. Read More
