Design modifications may improve range of motion following posteriorly stabilized total knee replacement: a matched pair study.

ABSTRACT:

Background

Our institution's latest knee implant design modifications aimed to decrease anterior knee pain, reduce the amount of bone that is resected in the femoral box, and improve range of motion.

Questions/purposes

Does this new knee design achieve desired clinical improvement in our patient population? This study was designed to compare our new design to that of its predecessor in a matched pair analysis.

Methods

A consecutive group of 100 knees underwent total knee arthroplasty using the newer box reamer (BR) posterior-stabilized design was matched by age, gender, and body mass index (BMI) to patients with the classic posterior-stabilized (PS) component. Average follow-up was 29.6 months (range 21-47) in the new group. Preoperative range of motion (ROM) and clin
