ABSTRACT
Objectives
We examined the relationship between the Japanese version of Patient-Rated Elbow Evaluation (PREE-J) and other established subjective and objective outcome measures in Japanese patients with rheumatoid arthritis (RA) who underwent total elbow arthroplasty (TEA).
Materials and Methods
This study involved 46 elbows of 40 RA patients. We collected clinical data 1 year after surgery, including the PREE-J, the Mayo Elbow Performance Score (MEPS), Disability of the Arm, Shoulder, and Hand (DASH), and Hand20. The correlation and responsiveness to PREE-J were evaluated compared with other outcome measures preoperatively and postoperatively.
Results
Almost all outcome measures were improved significantly after surgery. Preoperative PREE-J was significantly correlated with preoperative DASH, Hand20, and MEPS. Interestingly, postoperative PREE-J did not correlate with postoperative MEPS. Multiple regression analyses revealed that preoperative grip strength [B = −0.09; 95% confidence interval (95% CI) −0.17 to −0.01, p = 0.03] and preoperative Hand20 (B = 0.31, 95% CI 0.03–0.58, p = 0.03) were significant factors that might influence the postoperative PREE-J.
Conclusions
The PREE-J was shown to correlate well with other preoperative outcome measures among the RA patients included in the current study. The postoperative PREE-J after TEA was influenced by the preoperative grip strength and function of the hand.
