Risks and Harms of Implementing this Recommendation
There is no inherent harm in either approach or any associated complications other than the primary outcome of dislocation of the prosthesis postoperatively. This information should be considered in the context of both patient and surgeon specific factors when deciding on a surgical approach.
The existing evidence only compares posterior and lateral approaches and only allows comparison of dislocation as the primary end point. Future well designed RCTs should include a comparison of the increasingly popular anterior approach with either the posterior and/or the lateral approach. Any future studies related to surgical approach should also include functional data associated with the approaches. This may have important implications for patient selection and recovery needs such as assistive devices or therapy needs.
