Xiong H, Sun Z, Chen S, et al. - A retrospective study was performed to evaluate the clinical efficacy of patients with different uric acid levels after elbow arthrolysis. Researchers recruited a total of 131 patients with post-traumatic elbow stiffness who had undergone arthrolysis between March 2014 and March 2016. They classified all patients into 4 groups based on the preoperative serum level of uric acid. After arthrolysis, this research validates that in patients with post-traumatic elbow stiffness, abnormal serum uric acid metabolism was a risk factor for poor performance and postoperative pain. Thus, for assessment of the postoperative outcomes, detecting the preoperative serum uric acid levels of the patients would be helpful.
