We evaluated the clinical outcome after arthroscopic olecranon osteophyte resection without ligament operation in the elite baseball players who had valgus extension overload syndrome without moderate or severe medial collateral ligament injury. From January 2007 to December 2011, twelve patients underwent arthroscopic osteophyte resection without ligament operation and they were followed for more than 12 months. The mean age was 19.2 years and mean follow-up period was 26 months. The clinical results were evaluated using range of motion, visual analogue scale (VAS) and Mayo elbow performance score (MEPS). After checking osteophyte size and location through 3-dimensional computed tomography, arthroscopic osteophyte resection was performed. Average preoperative extension, flexion, pronation and supination were 2.3degrees, 138.2degrees, 76.4degrees, and 69.1degrees. Average postoperative extension, flexion, pronation and supination had been changed into 0.7degrees, 137.3degrees, 79.1degrees, and 77.3degrees. Average preoperative pain VAS and MEPS were 5.5 and 67.5. Average postoperative pain VAS and MEPS had been changed into 0.4 (p<0.001) and 97.5 (p<0.001). Eleven patients returned to play. Ten cases returned to their own position. No patients were performed other operation for elbow pain. The arthroscopic osteophyte resection in valgus extension overload syndrome with low grade medial ulnar collateral ligament (MUCL) injury or without MUCL injury was a one of the ideal treatment option for early return to pre-injury levels and relief of pain.
