Comparative StudyA comparison of total hip and knee replacement in specialty and general hospitals.
The emergence of specialty orthopaedic hospitals has generated widespread controversy, but little is known about the quality of care they deliver. Our objective was to compare the characteristics and outcomes of patients undergoing major joint replacement in specialty orthopaedic and general hospitals. ⋯ After adjustment for patient characteristics and hospital volume, the specialty orthopaedic hospitals had better patient outcomes, as measured by Medicare administrative data, than did the general hospitals.

Magnetic resonance imaging of arthroscopic supraspinatus tendon repair.
While a number of studies have documented the very good clinical results of arthroscopic rotator cuff repair, very few authors have specifically assessed cuff integrity, supraspinatus atrophy, and fatty infiltration and their influence on the clinical outcome. ⋯ The clinical and structural results of arthroscopic repairs of isolated supraspinatus tears are equal to those reported following open repair. Fatty infiltration and muscle atrophy cannot be reversed by successful arthroscopic repair. Higher degrees of muscular atrophy and fatty infiltration preoperatively are associated with recurrence of the tear as well as progression of fatty infiltration and muscular atrophy and an inferior clinical result.
