Complications of shoulder arthroplasty for osteoarthritis with posterior glenoid wear

Abstract

Level IV; retrospective case series.

Is reverse total shoulder arthroplasty (rTSA) more advantageous than anatomic TSA (aTSA) for osteoarthritis with intact cuff tendon? A systematic review and meta-analysis

“…Of these, 616 were excluded after screening the titles and abstracts, and 38 were excluded after a full-text review. Thus, six studies [ 1 , 8 , 10 , 15 , 23 , 27 ] were eligible for qualitative and quantitative data analysis. The agreement in study selection between the two reviewers was “substantial” at the title review stage ( κ = 0.777), “almost perfect” at the abstract review stage ( κ = 0.837), and “perfect” at the full-text review stage ( κ = 1.0).…”

“…All of the six included studies were retrospective cohort studies [ 1 , 8 , 10 , 15 , 23 , 27 ]. In total, 447 cases of glenohumeral arthritis treated with arthroplasty were reported, including 129 treated with rTSA and 318 treated with aTSA.…”

“…Regarding the eight main evaluation parameters, all six of the included studies lost a point for their retrospective study design and for not clearly describing the assessments (bias) of their endpoints. They also lost a point if the study size was not prospectively calculated [ 1 , 8 , 10 , 15 , 23 , 27 ]. In addition, five studies lost a point because they had a lost-to-follow-up rate of more than 5% of the initial patients [ 1 , 10 , 15 , 23 , 27 ].…”

“…Four studies [ 1 , 8 , 10 , 23 ] compared the ROM for FE and ER. The pooled analysis showed no difference in the degree of FE between the two arthroplasty systems (mean difference [MD] = − 2.92, 95% CI: − 8.42–2.57, P = 0.30, I 2 = 0%; Fig.…”

“…Glenoid loosening and scapular notching were reported in our included studies. In four studies [ 1 , 8 , 15 , 23 ], glenoid loosening was lower in the rTSA than in the aTSA group, with a pooled OR of 0.17 (95% CI: 0.06–0.50, P = 0.001; Fig. 4 A).…”
