“…Some authors argue that posterior compartment osteophytes, secondary to olecranon fossa shearing, may be adaptive changes to the thrower’s elbow, and that arthroscopic resection may destabilize the elbow. 12 , 13 , 18 , 19 , 20 Kamineni et al., indeed, demonstrated that excessive resection of posteromedial osteophytes leads to increased translation of the olecranon during elbow motion and a resultant increase in strain on the anterior bundle of the UCL. 12 , 13 While there was no difference in mean KJOC or Andrews-Timmerman scores in our analysis, there was a higher mean KJOC-Control score in the no impingement group (9.11 ± 1.32 vs 7.65 ± 2.40; P = .04), which may be explained by this destabilization theory following resection of posteromedial osteophytes.…”
