Physical therapy constitutes an essential determinant of clinical outcome a
fter total shoulder arthroplasty. We reviewed our results in 81 shoulders a
t a minimum of 2 years' follow-up, with specific focus on the maintenance o
f motion and the development of soft tissue healing problems. Our findings
show that our graduated rehabilitation program allows most patients to obta
in motion comparable to that possible intraoperatively with few complicatio
ns. Of patients, 70% maintained their elevation, and 90% maintained externa
l rotation. Patients with a diagnosis of rheumatoid arthritis, traumatic ar
thritis, and osteonecrosis were identified as being at risk for failure to
regain motion and for tendon healing complications.
