What is the effect of prior surgery on shoulder arthroplasty outcomes?

Impact of previous non-arthroplasty surgery on clinical outcomes after primary anatomic shoulder arthroplasty

These authors sought to determine the effect of previous non-arthroplasty surgery prior to primary anatomic shoulder arthroplasty. They conducted a review 640 patients undergoing anatomic shoulder arthroplasty (345 total shoulders and 295 ream-and-run arthroplasties). Of these patients, 183 (29%) had previous non-arthroplasty surgery.

They found that among patients undergoing total shoulder arthroplasty, previous non-arthroplasty surgery was associated with a significantly lower 2-year Simple Shoulder Test (SST) scores, percentages of maximum possible improvement (MPI), and Single Assessment Numeric Evaluation (SANE) scores (P <.001) and higher rates of reoperation. 

In patients undergoing ream-and-run arthroplasty, previous non-arthroplasty surgery was associated with insignificantly lower 2-year SST scores, percentages of MPI, and SANE scores and higher reoperation rates.



Prior fracture surgery carried a higher risk of reoperation than other types of prior surgery (e.g. rotator cuff repair and instability surgery).

Comment: This study shows that good clinical outcomes can be achieved with the ream and run procedure and with total shoulder arthroplasty, even in shoulders that have had prior surgery.
