Abstract
Introduction:
Total Ankle Replacement is proving to be a viable option for younger patients with Post Traumatic Osteoarthritis of the Ankle. The aim of our study was to study the clinical and patient reported outcomes between patients of < 60 and > 60 years who underwent TAR.
Method:
Patients who underwent a TAR between March 2006 and May 2009 were invited to take part in the hospital patient registry. They were divided into two groups based on Age (Group A-Age > 60 and Group B-Age < 60). Patient demographics, co-morbidities, Clinical (AOFAS) outcomes, patient reported outcomes (FAOS, SF-36, patient satisfaction) and complications were collected from patients pre-operatively and at 1, 2 and 3 years follow up. Comparisons were made between groups for all outcome measures.
Results:
There were 56 patients in Group A and 32 patients in Group B. There was no difference in Gender, side of operation and diagnosis reported between the 2 groups (P>0.05). Group A reported higher number of co-morbidities than Group B (1.54 vs. 1.00); p=0.032. There was no difference in AOFAS scores and FAOS scores for pain and function at all follow up times (p>0.05). Although Group B reported worse scores for FAOS stiffness pre-operatively (p=0.002) and at 1 year (p=0.029); there was no difference between scores at 2 and 3 years follow up. There was no difference in SF-36 scores and patient satisfaction and complications between groups. We expect to have the 4 year results processed by October this year.
Conclusion:
We have found satisfactory outcomes following TAR, both clinical and patient reported, irrespective of age of patient. Although long-term survivorship results for TAR are unavailable, we feel that younger age may not be a contra-indication to TAR as it provides good quality of life and potentially allows continuation of work.
