## Abstract Implant loosening is a common indication for total hip replacement (THR) revision. High contact forces and implant twisting moments are thought to be associated with implant loosening. Relationships between joint positioning and hip forces, or outcomes, have been investigated through in

โฆ Synopsis
Passive joint position sense was tested in 10 subjects after unilateral total hip replacement surgery (which included capsulectomy). Varied initial limb position, amplitude, and velocity of movement were used. The unoperated side was used as a control. Statistically barely significant errors (p less than 0.025) on the operated side were detected at 0.6 degrees per second but not at 2 degrees per second. No significant differences were noted among the different hip positions. The results indicate that the ability to detect passive hip joint position sense remains largely, but not completely, intact after hip joint replacement. The joint capsule, ligaments, and joint surfaces, although not essential for kinesthesia, may provide some limb movement and position information, the absence of which is not now clinically apparent.
