ABSTRACT
Tibial osteotomy is an effective surgical intervention for treating knee malalignment associated with pain or arthrosis in young and active patients. Although the techniques have evolved, the basic principle has been used for many years. The advent of improved fixation devices has allowed for earlier and more aggressive return to activity, resulting in the need for new rehabilitation guidelines that are individualized to patient pathology, expectations, and abilities.

Glenoid inclination has been associated with rotator cuff tears and superior humeral translation, but the relationship between glenoid inclination and superior humeral translation has not been assessed in vivo. This study compared glenoid inclination between repaired and contralateral shoulders in 21 unilateral rotator cuff repair patients. As a secondary analysis, we assessed the relationship between glenoid inclination and in vivo superior humeral translation. Glenoid inclination was measured from patient-specific, computed tomography-based bone models. Glenohumeral joint motion was measured from biplane radiographs collected during coronal-plane abductions. Glenoid inclination was significantly lower for the rotator cuff tear shoulders (90.7 degrees ) than the asymptomatic, contralateral shoulders (92.3 degrees , P = .04). No significant correlation existed between increased glenoid inclination and superior-inferior translation of the uninjured shoulder (P > .30). This study failed to support the theory that glenoid inclination is responsible for superior humeral translation and the development of subacromial impingement.
