A prospective comparison of short-term results after arthroscopic and open elbow procedures in elbow stiffness

Abstract

Background Surgical treatment of the stiff elbow can be performed either arthroscopically or via an open approach. There is a paucity of direct prospective comparisons of the techniques in the literature. Objectives The aim of the study is to analyze the clinical short-term results of arthroscopic and open elbow arthrolysis in postoperative and posttraumatic stiff elbows. Materials and methods The study group consisted of 44 patients divided in two cohorts, one after arthroscopic arthrolysis (33 patients) and the other including patients after open arthrolysis (11 patients). Range of motion (ROM; extension/flexion), pain (numerical rating scale, NRS), as well as the disabilities of the arm, shoulder, and hand (DASH) score were recorded preoperatively and examined in a standardized manner 6 weeks, 3 months, and 6 months after surgery. Results In both groups, preoperative elbow movement significantly improved in the follow-up. An increase from 103.3° (±23.4) to 123.5° (±12.5°; p = 0.001) was seen after 6 months for the arthroscopic group, whereas the mean ROM significantly increased from 64.5° (±31.1°) to 100.9° (±25.6°; p = 0.007) following open arthrolysis. In the arthroscopic group, the DASH score was measured at 37.3 points (±23.4 points) and improved to 16.1 points (±16.5 points) after 6 months, while in the open group it enhanced after 6 months (19.5 points [±17.5 points]) compared to its preoperative value by 38.2 points (±24.1 points). A consistent improvement was found for NRS, which decreased after surgery in both groups (arthroscopic group = −3.1 [±3.0]; open group = −2.0 [±2.9]). Complications did not occur in either group. When comparing delta values of the groups between the preoperative ROM, DASH score, and NRS, no significant differences were observed (p < 0.05). Conclusions Good to excellent functional recovery was seen in both cohorts when evaluating for improvement in the DASH score, the gain in elbow motion, and the decrease in pain. No significant differences were found between the procedures regarding pre- and postoperative measurements. The arthroscopic approach has developed to become an effective alternative to treat posttraumatic elbow stiffness.

“…Arthroscopic arthrolysis offers an alternative approach with similar patient satisfaction. 16 Comparative studies suggest open arthrolysis yields a higher (though not significant) gain in range of motion and complication rate. 16e18 Arthroscopic approach is technically demanding and relatively contraindicated in those requiring extra-articular procedures.…”
