Description
Muhamed Farhan-Alanie and co-authors pooled studies comparing two ball sizes in hip replacement surgery in a 2025 review. A larger ball should, in theory, resist dislocation because it must jump farther to escape. The worry is that it may also wear the plastic liner faster or strain the joint's taper. The team searched major databases and national registries and combined the results statistically.
Four studies and two registry reports were included, with follow up of a few years. The larger heads were linked to a marginal drop in revision surgery for dislocation, with the estimate just crossing the line of no effect. The review also tracked revision for all causes. Sensitivity checks limited to arthritis cases and modern liner types were planned. The study was registered publicly before the work began.
