The purpose of this research paper is to determine the most critical complications that arise following hip replacement, whether in the short or the long term. A sample of 25 hip replacement patients and 10 medical practitioners who interact with them was selected. Mixed methods were used to analyze the data. It was identified that blood clots, dislocation, fracture, differing leg lengths, and infection are the most common complications. However, of these, it was established that the incidence of blood clots and infections is the highest. That of differing leg lengths is the lowest. However, based on the responses of the medical practitioners, there is a high chance that the incidence of blood clots and infections is similar. Several challenges were faced in completing this study and these related to time and the difficulty of identifying the patients. The study has important implications for the profession and for future research.
