Abstract
Sixty-two consecutive revision hip arthroplasties were carried out in 57 patients between 1986 and 1990 using the long stem Porous Coated Anatomic (PCA) prosthesis. Fifty-two hips were available for clinical and radiological review. The remainder had either died or were lost to follow-up. The average follow-up was 4.8 years (range 3-7.8 years) and the mean age was 56 years (range 25-77 years).
Using the Harris Hip Score, 38/53 (73%) were regarded as good/excellent, 6/52 (11.5%) as fair and 8/52 (15.5%) as poor. The incidence of femoral component subsidence (31/52 - 60%) was a cause of concern, and accounted for two cases of late dislocation. Of the remaining six hips regarded as failures, two had been revised for acetabular graft resorption and migration of the cup while four had moderate persistent pain despite fair hip function. The authors are unable to recommend the long stem PCA prosthesis for routine use in revision hip arthroplasty.
