Strengths and Limitations
patellar dislocation, pain
The strength of this study was focusing on analgesia management after surgical treatment of RPD. ACB is a safety and reliable management. The analgesia management of ACB + GA showed excellent pain release and was good for early rehabilitation. Moreover, this study is an RCT, and the evidence stage is level I. The limitations were as follows: First, this trial was a small‐sample, single‐center, preliminary exploratory trial. Further multicenter studies with larger sample sizes are required. Second, the type, concentration, and volume of analgesics were relatively simple and subgroup analysis was not performed in the ACB + GA group. Third, due to the patellar ligament and quadriceps tendon operation for recurrent patellar dislocation, the protocol to measure quadriceps strength in this trial could not accurately evaluate the strength in the early postoperative period. Despite these limitations, the findings in this study deserve attention.
