Characterizing the effect of diagnosis on presenting deficits and outcomes after total shoulder arthroplasty.
This study compared self-assessed deficits in comfort, function, and health status before and after total shoulder arthroplasty for 4 different diagnoses: degenerative joint disease (DJD), secondary DJD (2 degrees DJD), rheumatoid arthritis (RA), and capsulorrhaphy arthropathy (CA). Deficits were assessed by the Simple Shoulder Test and Short Form 36 (SF-36) questionnaires. There was a significant difference among diagnoses for preoperative and postoperative functional deficits. The profiles of improvement within the categories of comfort, motion, strength, and function were different for each diagnosis. Patients with DJD and CA were most improved in the category of motion, whereas those with 2 degrees DJD and RA were most improved in the category of comfort. There was also a statistically significant difference in 5 of the 8 domains of the preoperative SF-36 among diagnoses. Factors associated with each diagnosis play a significant role in determining the magnitude of preoperative deficits and postoperative improvement in shoulder function.
