Hybrid hip arthroplasty in the younger patient. Quality of life

In a hybrid hip arthroplasty, the acetabular component is uncemented. Without screw fixation, early stability depends on a press-fit. The demands placed on it by the younger patient may therefore be important. Eighty patients under the age of 70 before and after hybrid or Charnley hip arthroplasty were studied. Scores for disability and distress were used to generate quality-of-life (QOL) scores using the Rosser Index Matrix immediately before and at 1 year after surgery. All patients increased their QOL scores (P < .00006). Both groups had similar QOL scores before surgery (P = .596). At 1 year, patients with the hybrid prosthesis had slightly higher scores (P = .015). Changes in QOL scores were, however, very similar (P = .697). The use of a hybrid prosthesis does not impair early outcome.
