219 hips in 192 patients diagnosed with degenerative hip joint disease, were randomly assigned to treatment with either metal-on-metal hip resurfacing or total hip replacement. The purpose was to compare to two in terms of clinical benefits, metal ion levels, and radiographic outcomes over 8 years after treatment. The results of the study indicated that for young patients suffering from hip joint degeneration, both total hip replacement and hip resurfacing result in similar, improving clinical outcomes and revision rates approximately 8 years postoperatively. Osteolysis was observed more frequently with THR, while higher titanium levels were found in patients who received HR.
