The Clinical Impact of Revision TSA for Glenoid Component Loosening
Like total hip and total knee arthroplasty, total shoulder arthroplasty (TSA) is a generally successful procedure that offers patients improved functional outcomes and pain relief.But like the procedures in the hip and knee, TSAs can fail due to component loosening, leading to revision surgery.
How patients fare over the long term following the revision procedure for glenoid component loosening was the subject of a study from Mayo Clinic, Rochester, Minnesota, that was recently presented at the Mid-America Orthopaedic Association’s annual meeting.
The researchers followed 31 patients who underwent a revision TSA with either placement of a new glenoid component or removal of the glenoid component and bone grafting for a mean of 8.3 years. These patients had significant improvement in their pain scores, but their functional improvements were not as dramatic: Although active abduction, external rotation, and internal rotation improved, the improvements were not statistically significant.
