Correlates of functional outcome of primary uncemented total hip arthroplasty

Abstract

Total hip arthroplasty evolved as a result of many improvements of designs of components, availability of suitable component materials and manufacturing techniques. To contend successfully with the many problems that occur and to evaluate new concepts and implants, a working knowledge of biomechanical principles, materials, and design also is necessary. The metal-on-polyethylene articulation remains the standard in total hip arthroplasty. All the patients were contacted for clinical and radiological assessment through postal and personal communication. All 22 patients attended the review arthritis clinic on a previously provided appointment date. The diagnosis, preoperative assessment, operation records and follow up radiographs of these patients were systematically reviewed from the available hospital data. There was no statistical significance in the final outcome with relation to age, sex, laterality, femoral stem size, acetabular cup size or for acetabular inclination angle.
