Key Points

This research aims to compare the postoperative pain outcomes between total hip arthroplasty and total knee arthroplasty in osteoarthritis patients.
Retrospective review of patients undergoing unilateral total hip or knee arthroplasty.
Inclusion of 1,373 THA and 1,428 TKA patients using a web-based home therapy program.
Followed Visual Analog Scale pain scores from 30 days preoperatively to 90 days postoperatively.
Mean pre- and post-operative pain scores compared using multivariate linear regression analyses.
THA patients had higher mean preoperative pain scores (0.7 points) compared to TKA patients (P < 0.001).
THA patients experienced a larger drop in pain scores (1.8 points) within one week of surgery.
THA patients noted an earlier drop and plateau in pain scores than TKA patients (58 vs. 77 days).
Postoperative pain levels were lower in THA patients by 0.9 points, suggesting better pain relief (P < 0.001).

Implication

Retrospective review shows total hip arthroplasty improves pain scores earlier than total knee arthroplasty in patients with osteoarthritis, suggesting better pain management outcomes.
