Background
Surgical methods in treatment of joint osteoarthritis (OA) aim at meeting the increasing expectations of people with active lifestyles. Ankle joint arthroplasty has been performed increasingly more often as an alternative to arthrodesis. The aim of this study was to compare arthrodesis and arthroplasty in the treatment of ankle osteoarthritis.
Material/Methods
The study involved 56 patients (45 males and 11 females) aged 21–72 years (mean 51) presenting with end-stage ankle OA: 29 patients (52%) underwent arthroplasty (Group A) and 27 patients (48%) underwent arthrodesis (Group B). Patients underwent surgery between 2004 and 2016 at a single clinical center. The observation period ranged from 6 to 150 months (mean 55 months). To assess the results of surgical treatment, quality of life (Health Assessment Questionnaire-HAQ, 12-Item Short-Form Survey-SF-12) and functional (American Orthopedic Foot & Ankle-AOFAS, Kofoed, Takakura) scores were used. For pain assessment, Visual Analog Scale was used (VAS).
Results
After the surgery, group A and B had a statistically significant improvement in the joint function and pain relief according to AOFAS (A: 32.6 to 68.2; B: 27.4 to 61.3), Kofoed (A: 31.8 to 68; B: 25.9 to 60.3), Takakura (A: 30.6 to 62.9; B: 25.4 to 49.3), and VAS scores (A: 7.28 to 4.14; B: 7.33 to 3.78) compared with preoperative scores. After the surgery, quality of life scores improved in both groups, for HAQ (A: 0.91 to 0.53; B: 1.34 to 0.56) and for SF-12 (A: 26.6 to 36.8; B: 25.6 to 38.0).
Conclusions
The comparison of total ankle arthroplasty and ankle arthrodesis in treatment of end-stage ankle osteoarthritis did not reveal any significant differences.
