The Effect of Patellar Eversion on Functional Outcomes in Primary Total Knee Arthroplasty

Patients randomized to the eversion group had patellas everted during the flexion portions of the surgery. Patients randomized to the retraction group had patellas everted only for the patellar resurfacing portions of the surgery. Both groups were mobilized with anterior tibial translation. All other aspects of surgery including postoperative care, anticoagulation, pain control, and physical therapy were done as per standard arthroplasty protocols at our institution.
