NCT03341442

Brief Summary

The purpose of this study is to perform a randomized controlled study to compare patients undergoing THA via a posterolateral approach to receive either standard of care post-surgery hip restrictions or to receive no restrictions. The investigators goal is to first complete a pilot study in which the investigators assess the short term dislocation rates 3-6 months and then continue to recruit into this study and follow these patients for a year to determine the 1 year risk for dislocation. The investigators also will compare the HOOS Jr. and VAS scores and time until free from walking aid. The research question is: Will the elimination of post operative posterior hip precautions increase the dislocation rate? The hypothesis is that the elimination of post operative hip precautions will not increase the dislocation rate.
