A review of role of osteotomy in knee ligament injuries.

Realignment osteotomies around the knee joint are used primarily for management of arthritis. Traditionally, an unstable knee has been considered a contraindication for osteotomy. But with a better understanding of biomechanics of osteotomies and their effect on ligament instabilities, the beneficial role of osteotomies in managing an unstable knee is becoming clearer.

Biomechanical comparison of graft structures in anterior cruciate ligament reconstruction.

Purpose: Double-bundle (DB) anterior cruciate ligament (ACL) reconstruction may offer kinematic restoration superior to anatomic single bundle (SB), but it remains technically challenging. The femoral attachment site has the most effect on ACL graft isometry, so a simplified three-socket (3S) construct which still uses two sockets to cover the femoral ACL attachment is attractive. It was hypothesised that ACL reconstruction using three- and four-socket techniques would more closely restore native knee kinematics compared to anatomic two-socket (SB) surgery.

Baked beans in the knee? An odd-looking synovial swelling in the knee joint.

Lipoma arborescens (LA) is a rare benign neoplasm affecting large synovial joints, most commonly seen in the knee joint. Unlike other common swellings around the knee joint, LA is intra-articular and can lead to degenerative changes in the knee joint due to mechanical impingement. The importance of correct diagnosis with characteristic MR and macroscopic appearance and appropriate surgical treatment is outlined in this case report.

Unipolar versus bipolar uncemented hemiarthroplasty for elderly patients with displaced intracapsular femoral neck fractures.

Purpose: To compare outcomes of unipolar versus bipolar uncemented hemiarthroplasty and determine factors affecting outcomes.

Methods: 433 and 274 elderly patients with displaced intracapsular femoral neck fractures underwent uncemented unipolar hemiarthroplasty and uncemented bipolar hydroxyapatite-coated hemiarthroplasty, respectively. Surgical options were based on the patient's general condition and preinjury mobility status.
