Shoulder arthroplasty to address the sequelae of anterior instability arthropathy and stabilization procedures: systematic review and meta-analysis.

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.
