title: Efficacy of periarticular injection applied trough knee other than posterior capsule in simultaneous bilateral total knee arthroplasty.
abstract: 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.
