Pain Relief, Motion, and Function after Rotator Cuff Repair or Reconstruction May Not Persist after 16 Years
Short- to medium-term rotator cuff repair reportedly relieves pain in 82% to 97% of patients and provides normal or almost normal shoulder function in 82% to 92%. However, it is unknown whether pain relief and function persist long term.
Parkinson’s disease is a relatively common problem in geriatric patients with an annual incidence rate of 20.5 per 100,000. These patients are at increased risk for falls and resultant fractures. Several reports suggest total shoulder arthroplasty in patients with fractures has a relatively high rate of complications. Whether hemiarthroplasty reduces the rate of complications or improves pain or function is not known.
Cemented and uncemented stem types are available for TSA. An early uncemented stem designed for bone ingrowth had radiographic loosening of approximately 10% at intermediate followup (mean 4.6 years). Subsequent stem modifications included circumferential metaphyseal porous coating to enhance ingrowth and reduce loosening rates.
Acute idiopathic chondrolysis in young adults is rare. The etiology often is unknown and outcomes can be devastating owing to rapid development of painful secondary osteoarthritis. There have been some recent reports of chondrolysis after arthroscopic shoulder procedures. Animal and laboratory data suggest chondrolysis is related to the use of intraarticular pain pumps, although there is no conclusive evidence that this is causative in patients.
