Anatomic findings and complications after surgical treatment of chronic, partial distal biceps tendon tears: a case cohort comparison study.

Purpose: To describe pertinent anatomic findings during repair of chronic, partial distal biceps tendon tears and to compare the complications of surgery with a similar cohort of acute, complete tears.

Methods: Group 1 included 14 patients (15 elbows) with partial tears managed operatively an average of 10 months from onset of injury or symptoms. Group 2 included a matched cohort of 16 patients (17 elbows) treated for complete, acute tears an average of 19 days from injury.

Screw osteolysis in the cementless anatomic modular knee arthroplasty.

A cohort of patients underwent prospective follow-up to delineate the natural history of screw-associated osteolysis in cementless Anatomic Modular Knee arthroplasty. In 1993, fluoroscopically guided radiographs were obtained in 230 patients (280 arthroplasties) to identify occult osteolysis. This cohort was reassessed periodically to identify new or progressive screw-associated osteolysis.

Randomized controlled noninferiority trial to compare extended release acetaminophen and ibuprofen for the treatment of ankle sprains.

Study Objective: To compare acetaminophen extended release 1,300 mg 3 times daily and ibuprofen 400 mg 3 times daily for treatment of signs and symptoms of grade I or II lateral ankle sprains.

Methods: Patients (N=260) 18 years or older and with grade I or II lateral ankle sprains were randomized to receive acetaminophen extended release 1,300 mg 3 times daily or ibuprofen 400 mg 3 times daily for 9 days. Primary endpoint was change from baseline at day 4 in pain on walking.
