Medial Patellofemoral Ligament Reconstruction

Recurrent patellofemoral instability is a common disabling condition especially in young individuals. MPFL is the main stabilizer to lateral patellar displacement and its reconstruction will restore patellofemoral stability. Many techniques had been described to reconstruct MPFL with good results and few complications taking in consideration meticulous surgical technique and careful patient selection. We used hamstring autograft in a double bundle anatomic MPFL reconstruction technique with both ends of the graft fixed to patella through two blind tunnels by anchor and bioabsorbable interference screw fixing the graft through a blind tunnel in the femur at 30 degree flexion

Giant Cell Tumor of Tendon Sheath in the Knee

The giant cell tumor of the tendon sheath (GCTTS) is a benign lesion which arises from the synovium of a joint, bursa or tendon sheath, with 85% of the tumors occurring in the fingers and 12% of the tumors located in large joints such as the knee and ankle. The GCTTS is usually monoarticular, slowly proliferative and rarely locally aggressive. This paper reports three cases of this rare lesion in the knee. Patients presented with painful swelling in the anterior knee, MRI showed localized soft tissue masses which were able to be excised. A follow up of the cases showed no recurrences. This case report emphasizes the importance of considering GCTTS in the differential diagnosis of soft tissue swelling and pain in large joints
