Press-fit fixation using autologous bone in the tibial canal causes less enlargement of bone tunnel diameter in ACL reconstruction--a CT scan analysis three months postoperatively.

Background: Bone tunnel enlargement is a phenomenon present in all anterior cruciate ligament (ACL)- reconstruction techniques. It was hypothesized that press-fit fixation using a free autograft bone plug reduces the overall tunnel size in the tibial tunnel.

Methods: In a prospective cohort study twelve patients who underwent primary ACL reconstruction using an autologous quadriceps tendon graft and adding a free bone block for press-fit fixation (PF) in the tibial tunnel were matched to twelve patients who underwent ACL reconstruction with a hamstring graft and interference screw fixation (IF).

Rolimeter measurements are suitable as substitutes to stress radiographs in the evaluation of posterior knee laxity.

Purpose: The quantification of posterior knee laxity is crucial in the evaluation of injuries to the posterior cruciate ligament (PCL) as it has important implications to the treatment for these injuries. The objective of this study was to compare the test results of stress radiography and instrumented drawer testing (Rolimeter) for the assessment of posterior knee laxity in patients with PCL injury.

Methods: In 45 patients with an injury to the PCL, lateral radiographs of both knees were obtained under anterior and posterior tibial load (150 N) using a standardized approach.

Excellent results of lesser tuberosity transfer in acute locked posterior shoulder dislocation.

Purpose: The aim of the present study was to evaluate the clinical and radiological results of lesser tuberosity transfer in acute locked posterior shoulder dislocation with a humeral head defect between 25 and 45 %.

Methods: Clinical and radiological results of seven patients with locked posterior shoulder dislocation with a humeral head defect between 25 and 45 % which were managed with a modification of the McLaughlin procedure within 14 days after injury were evaluated retrospectively after a mean follow-up of 41 months.

Results: All shoulders remained stable.
