Outcomes and complications following total hip arthroplasty in the super-obese patient, BMI > 50.

The results of total hip arthroplasty in 42 primary total hip arthroplasties in super-obese patients (BMI ≥ 50) were reviewed. The mean body mass index for the study group was 53.2 kg/m(2) (range 50-64).

Factors associated with excellent 6-month functional and isokinetic test results following ACL reconstruction.

Purpose: To identify patient concomitant injury and surgical characteristics associated with 6-month excellent functional and isokinetic testing results following anterior cruciate ligament (ACL) reconstruction.

Methods: Patients that underwent ACL reconstruction by a single surgeon had isokinetic and functional testing performed with excellent 6-month outcome defined as greater than 85 % in isokinetic strength and 90 % in functional tests (excellent 6-month group vs. delayed 6-month group).

The Shenton line in the diagnosis of acetabular dysplasia in the skeletally mature patient.

Background: Undetected developmental dysplasia of the hip can progress to hip instability, which can lead to the development of early osteoarthritis. The purpose of the present study was to determine the reliability and accuracy of the Shenton line in the diagnosis of acetabular dysplasia in the skeletally mature patient.

Methods: Supine anteroposterior pelvic radiographs were obtained for a total of 128 hips in patients with a diagnosis of developmental dysplasia of the hip prior to pelvic osteotomy (sixty-four hips, including thirty-two left and thirty-two right hips) and normal patients (sixty-four hips, including thirty-two left and thirty-two right hips).
