Abstract:
Objective To investigate the mid?term efficacy of extracapsular arthroscopic surgery for refractory tennis elbow and explore prognostic factors. Methods A retrospective study of 38 patients suffered from refractory tennis elbow and underwent extracapsular arthroscopic surgery performed by the same group of doctors during March 2012 to January 2016 at Institute of Sports Medicine, Peking University Third Hospital. There were 15 males and 23 females with age of 44.2 years(range:32-59 years). Fifteen cases on the left and 23 cases on the right. Visual analogue scale(VAS), Mayo elbow performance score and Disability of Army, Shoulder and Hand (DASH) score were collected preoperatively and postoperatively, and compared by paired?t test. Independent sample t test, χ2 test, multivariate logistic regression were used to analyze the relationship between scores and various potential influencing factors. Results All 38 patients were followed up for 24 months. There was no complication such as infection or nerve injury recorded. VAS decreased from 7.0(1.2) (M(QR)) preoperative to 0(1) (Z=-5.40, P=0.00), Mayo increased from 55(26) to 100(0) (Z=-5.38,P=0.00),DASH decreased from 56.7(27.3) to 0.8(5.8)(Z=-5.37,P=0.00). The Mayo elbow performance score was excellent in 36 cases (94.7%) and good in 2 cases (5.3%). Women was significantly associated with poor prognosis. Conclusions The mid?term effect of extracapsular arthroscopic treatment of refractory tennis elbow is satisfactory with few postoperative complications. Women was associated with poor prognosis.
