RELATIONSHIP OF TOTAL HIP-ARTHROPLASTY OUTCOMES TO OTHER ORTHOPEDIC PROCEDURES

The Medical Outcomes Study Short Form-36 was used preoperatively and 2 years postoperatively to compare patients' self reported assessment o f health and function between 151 patients who had primary total hip r eplacement and 49 patients who had total hip revision, 149 patients wh o had primary total knee replacements, 41 patients who had lumbar lami nectomy, and 43 patients who had scoliosis surgery, Primary total hip arthroplasty and lumbar laminectomy posted equivalent followup scores, Primary total hip arthroplasty showed significant improvements in phy sical function and health perception when compared with revision total hip arthroplasty; all other health parameters were similar, Primary t otal hip arthroplasty showed significantly better followup scores and greater improvement in scores in four of nine categories of the SF-36 when compared with primary total knee arthroplasty (despite identical scores preoperatively), Despite a higher level of assessed health preo peratively, patients who had scoliosis surgery compared least favorabl y with patients who had primary total hip arthroplasty at 2 years foll owup, Tn terms of patient self assessment of health and function, prim ary total hip arthroplasty and lumbar laminectomy for radiculopathy ga ve the best results.
