Summary

Short and long term outcomes of total knee arthroplasty patients surgically exposed with patellar eversion are compared to those patients exposed by laterally retracting the patella. It was hypothesized that there would be no difference.

Detailed description

Background: Patellar mobilization during total knee arthroplasty (TKA) has been debated, with some proponents of minimally invasive TKA suggesting that laterally retracting, rather than everting the patella may be beneficial. It was our hypothesis that by using randomized, prospective, blinded study methods, there would be no significant difference in clinical outcome measures based solely on eversion of the patella during total knee arthroplasty. Methods: After an a priori power analysis was done, 120 primary total knee replacements indicated for degenerative joint disease were included in the study and randomized to one of two patella exposure techniques: lateral retraction or eversion. Collaborating investigators and patients were blinded to randomization.

Conditions

• Total Knee Replacement
• Arthroplasty
• Patella

Interventions

Type	Name	Description
PROCEDURE	Primary Total Knee Replacement Surgery	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.
