Abstract

|
|
Purpose: To analyze the prognostic factors influencing clinical outcomes and to aid the surgeon’s decision making concerning conversion of ankylosed hip to total hip arthroplasty (THA).
Materials & Methods: Forty-six patients (53 hips) with a mean follow-up duration of 3 years 4 months were
studied. Prognostic factors including type of ankylosis, age at fusion, abductor development, fusion duration,
preceding diseases, leg length discrepancy, implant type, and trochanteric osteotomy were analyzed. Clinical results
were evaluated retrospectively using Harris hip score (HHS; pain, gait, activity), pain scale of adjacent joints, and
range of motion.
Results: Favorable prognosis factors were severe fibrous ankylosis, spontaneous ankylosis, and age at fusion over 15 years. Unfavorable factors were bony ankylosis, surgical ankylosis, and age at fusion under 15 years in HHS and
pain scale of adjacent joints. Strong contraction of the abductor muscle was also an important prognosis factor in
HHS, especially in gait.
Conclusion: In conversion of ankylosed hip to THA, it is important to recognize the possible prognostic factors
and to meet the patient’s various demands and needs.
