Knee

Background

We aimed to evaluate periarticular multimodal drug injection (PMDI) in bilateral total knee arthroplasty.

Methods

In 154 knees of 77 patients, PMDI was administered intraoperatively through the regions other than posterior capsule to one knee; other knee was control.

Results

Drug-injected knees had lower visual analog scale scores and higher passive range of motion postoperatively (p < 0.05). The active straight leg raise was higher in drug-injected knees (47 [61%] vs 19 [24.7%], p = 0.001).

Conclusions

PMDI is a safe and effective method of early postoperative pain management in total knee arthroplasty when applied through regions other than posterior capsule.
