Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This project is designed to use MRI to evaluate pre- and post-arthroplasty hips; the specific aims of this project are three-fold. First, the investigators intend to compare the amount of muscle atrophy and tendon damage that occurs around the hip between two commonly-used operative approaches: the direct-anterior approach and the posterior approach. Second, the investigators aim to provide baseline data on the amount of muscle atrophy and tendon damage that should reasonably be expected to occur with both of these approaches. Third, the investigators will document the degree of recovery of the periprosthetic soft tissues post-surgery in both patient groups.

The investigators first hypothesis is that the posterior approach will demonstrate significantly more damage to the abductors, piriformis, and short external rotators than the direct anterior approach, which will demonstrate minimal soft tissue damage. The investigators second hypothesis is that both surgical approaches will cause some degree of baseline muscle damage and atrophy, in a predictable pattern. The investigators third hypothesis is that each of the surgical approaches inherently cause some degree of soft tissue damage, and that the periprosthetic soft tissues that are incised during the surgical exposure will recover in a predictable pattern which is consistent but unique within each group
