Sharplin PK, Frampton CMA, Hirner M, et al. - Researchers applied the New Zealand Joint Registry (NZJR) to correlate all-cause revision rates and functional scores for total shoulder arthroplasty (TSA) and evaluated the trends of glenoid fixation applied in New Zealand. This study evaluated NZJR for all primary TSA undertaken for OA from January 2000 to December 2017. They examined Oxford Shoulder Scores at both 6 months and 5 years. During the study period, a sum of 2,613 TSAs was conducted for OA, representing 85.0% of all TSAs in New Zealand. When the glenoid component is uncemented, primary TSAs undertaken for OA have a significantly higher all-cause revision rate in the NZJR. The data reveal that uncemented glenoids have a 5.0 times higher revision rate. The significantly higher revision rate remained for uncemented glenoids, excluding SMR L2 glenoids from the analysis. These outcomes reaffirm that uncemented MB glenoids are correlated with higher revision rates.
