Obturator hernia presenting as hip pain: a case report.

We report an 86-year-old women with an obturator hernia presenting with recurrent right hip pain. Obturator hernia is a diagnostic challenge because the hernial mass is usually concealed beneath the pectineus. It should be suspected in emaciated, multiparous, elderly women presenting with unexplained pain in the groin, hip, thigh, or knee.

Patellar clunk syndrome after posterior stabilized total knee arthroplasty.

Two hundred thirty-six posterior stabilized total knee arthroplasties (TKAs) were performed consecutively. Twenty-seven patellar clunk syndromes were identified in 25 patients. Insall-Salvati ratio, position of joint line, postoperative patellar height, and anterior-posterior position of tibial tray were measured.

Acetabular revision without cement.

The American Academy of Orthopaedic Surgeons (AAOS) acetabular defect classification was type I in 4 hips, type II in 9 hips, and type III in 32 hips.
