In a follow-up study of 156 patients after knee ligament reconstruction for chronic instability, the results of subjective Lysholm score grading and of Tegner activity grading were compared. The postoperative Lysholm score averaged 85 +/- 13.2 points, the activity scores 6.9 +/- 0.9 points prior to instability, 1.7 +/- 0.9 points preoperatively and 5.9 +/- 1.2 points postoperatively. 89 patients reached their preinjury activity level, the average improvement through surgery was 4.2 +/- 1.6 points. Non-active patients regularly returned to their original activity-level, competitive athletes were less likely to regain their previous activity. The subjective results of athletes and non-athletes showed no significant differences. The postoperative activity level clearly correlated to subjective grading by the patient. For scoring results after knee ligament surgery, we use the subjective Lysholm score and an activity score based on average German sports activities.

Degenerative arthrosis of the shoulder is less commonly||| diagnosed than at the joints of the lower extremity. The shoulder joint does||| not bear weight and some of the mechanical stresses are taken up by the||| subacromial space. However, anatomical studies reveal a significant incidence||| of degenerative changes at the glenohumeral joint with increasing age.||| Arthrosis is caused by mechanical loading, rotator cuff defects, and abnormal||| joint motion following surgery. Clinical symptoms are rarely focused on the||| glenohumeral joint. Clinical findings are also unspecific. Rotation of the||| elevated arm with compression of the joint is a reliable sign of arthrosis. The||| diagnosis is made with anteroposterior and axial radiographs. Ultrasonography||| should always be performed and computed tomography only in specific cases.||| Nonoperative treatment includes analgesic and antiphlogistic medication, motion||| therapy, and muscle exercises. Shoulder arthroplasty is favoured in advanced||| arthrosis. New prostheses are intended to reconstruct the normal anatomy as||| closely as possible.
