Randomized Controlled Trial Comparative Study
The use of exparel (liposomal bupivacaine) to manage postoperative pain in unilateral total knee arthroplasty patients.
Efforts continue to improve pain after total knee arthroplasty (TKA) in order to allow for accelerated rehabilitation. The purpose of this study was to evaluate pain control after TKA. A randomized prospective study of 80 consecutive patients was performed comparing Exparel versus femoral nerve block (FNB). ⋯ There were no statistically significant differences between the groups with regard to pain, nausea and vomiting, and narcotic consumption. The FNB group had greater flexion but the Exparel group had improved early ambulation and decreased LOS. Exparel provided similar pain relief to a FNB after TKA without compromising early rehabilitation.

Randomized Controlled Trial
Selective patellar resurfacing in total knee arthroplasty: a prospective, randomized, double-blind study.
350 knees were evaluated in a prospective, randomized, double-blinded study of selective patellar resurfacing in primary total knee arthroplasty. Knees with exposed bone on the patellar articular surface were excluded. 327 knees were evaluated at a mean follow-up of 7.8years. 114 knees followed for greater than 10 years were analyzed separately. Satisfaction was higher in patients with a resurfaced patella. ⋯ No complications of patellar resurfacing were identified. The vast majority of patients with remaining patellar articular cartilage do very well with total knee arthroplasty regardless of patellar resurfacing. Patient satisfaction may be slightly higher with patellar resurfacing.
