Simultaneous arthroscopic reconstruction of the anterior and posterior cruciate ligament using hamstring and quadriceps tendon autografts.

Background: Most dislocated knees involved tears in the two cruciate ligaments were often accompanied by other collateral ligament complexes. Surgical repair or reconstruction seems to achieve results superior to conservative treatment. Various methods of reconstructing anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) after knee dislocation have been described, but few reports discuss simultaneous ACL and PCL reconstructions in a single operation.

Improved divergence angles with femoral interference screw placement through the tibial tunnel as measured by multiplanar reconstruction computed tomography.

Purpose: A modified technique for anterior cruciate ligament (ACL) reconstruction without graft injury by femoral interference screw insertion directly through the tibial tunnel is reported. This study evaluated femur bioabsorbable interference screw divergence and obliquity of the graft and tunnel positions as measured by multiplanar reconstruction computed tomography (MPR-CT) after endoscopic ACL reconstruction.

Methods: Twenty-five patients who underwent single-incision arthroscopically assisted ACL reconstruction using hamstring tendon autografts were enrolled in this prospective study.

New vertebral fracture after vertebroplasty.

Background: Because the complications of vertebroplasty are serious and can include new fracture, we retrospectively evaluated potential risk factors for new fracture after vertebroplasty. Our hypothesis is that thoracolumbar vertebrae adjacent to a vertebroplasty site have a higher incidence of new compression fracture than do other vertebrae.

Methods: Between March 2001 and December 2002, a total of 271 patients underwent vertebroplasty and a retrospective review of charts was performed.

Arthroscopy-assisted surgery for tibial plateau fractures: 2- to 10-year follow-up results.

Purpose: This study evaluated the outcome of arthroscopy-assisted reduction with internal fixation for treating tibial plateau fractures at 2- to 10-year follow-up.

Methods: Fifty-four patients with tibial plateau fractures treated by arthroscopy-assisted reduction with internal fixation were enrolled in this prospective study. According to the Schatzker classification, the fractures types were as follows: type I, 1 (2%); type II, 21 (39%); type III, 4 (7%); type IV, 10 (19%); type V, 8 (15%); and type VI, 10 (19%).

Arthroscopic evaluation of soft tissue injuries in tibial plateau fractures: retrospective analysis of 98 cases.

Purpose: This investigation arthroscopically assesses the frequency of soft tissue injury in tibial plateau fracture according to the severity of fracture patterns. We hypothesized that use of arthroscopy to evaluate soft tissue injury in tibial plateau fractures would reveal a greater number of associated injuries than have previously been reported.

Methods: From March 1996 to December 2003, 98 patients with closed tibial plateau fractures were treated with arthroscopically assisted reduction and osteosynthesis, with precise diagnosis and management of associated soft tissue injuries.

Complications of hip arthroscopy: analysis of seventy three cases.

Background: Hip arthroscopy is recognized as a highly effective means of treating joint disorders. Complications in hip arthroscopy, including neurovascular traction injury, compression injury to the perineum and scope trauma, have been reported. We report our experience with 73 hip arthroscopy procedures and complications at Chang Gung Memorial Hospital.
