Complication and reoperation rates are higher compared to shoulder arthroplasty for primary glenohumeral joint arthritis ; however , the difference is not statistically significant .
When reverse shoulder arthroplasties ( RSA ) were considered as a subgroup and compared to anatomic shoulder replacements ( total shoulders and hemiarthroplasties ) , they showed a lower revision rate
Chronic anterior glenohumeral joint instability is a common situation and can lead to progressive cartilage deterioration and ultimately instability arthopathy .
Progressive cartilage deterioration can occur despite conservative or surgical treatment and the sequelae of these conditions are often addressed with total shoulder arthroplasty .
Aims of the present study were to analyze the available literature to describe the technical aspects of this particular operation and to report outcomes and complication rates .
The hypothesis was that shoulder arthropalsty in the sequelae of instability had lower outcomes and higher complication rates than arthroplasties for primary arthritis .
Shoulder arthroplasty to address the sequelae of instability arthropathy and stabilization procedures can be a challenging procedure as a consequence of the distorted anatomy and severe glenohumeral joint pathology .
The Prevalence of Glenohumeral Osteoarthrosis in Unstable Shoulders *
Background Glenohumeral osteoarthritis has been a well-described complication of open procedures to correct shoulder instability . What remains unknown is whether chondral injuries sustained during instability episodes contribute to osteoarthritis or whether the cause is primarily the stabilization procedure itself . Purpose To determine the prevalence of osteoarthrosis in a large data base of patients with acute and chronic shoulder instability before primary stabilization surgery . Study Design Retrospective review of prospect ively collected data . Methods Surgical and demographic data were collected on 422 patients with a diagnosis of shoulder instability who underwent arthroscopic examination and shoulder stabilization .  Results There was a significant association between the grade of osteoarthrosis and the presence of osteoarthritis ( grade III or IV chondral damage ) with time from injury to surgery . Patients with osteoarthritis  were significantly older than those without ( 34.9 versus 29.6 years ) . Multivariate analysis identified older age and time from injury to surgery as independent predictors of osteoarthritis . We found no association between direction of instability and the presence of osteoarthritis . Conclusion The overall prevalence of glenohumeral osteoarthrosis was low . Predictors of osteoarthritis included time from injury to surgery and age
