Abstract
Aim
We aimed to study the effect of BMI on clinical and patient-reported outcomes in patients with TAR with a minimum follow-up of three years.
Method
Patients who underwent a TAR between March 2006 and May 2009 were invited to take part in the hospital patient registry. Patients were divided into two groups based on BMI (Group A – BMI <30 and Group B – BMI >30). Patient demographics, co-morbidities, clinical (AOFAS), patient reported outcomes (FAOS, SF-36, patient satisfaction) and complications were collected pre-operatively and at 1, 2 and 3 years and comparison made between groups.
Results
There were 50 patients in group A and 31 in group B. There was no significant difference between age (Mean 64.5 (A) and Mean 61.3 (B), gender and side of operation between the groups (p>0.05). Group A had higher percentage of patients with OA and RA compared to Group B (p=0.027). Group B (1.16) reported higher co-morbidites than Group A (1.81); p=0.012. There was no difference in AOFAS scores, FAOS scores (for pain, function and stiffness) and SF-36 scores reported between groups at 1, 2 and 3 years post-operatively (p>0.05). At 3 years, Group B reported less patient satisfaction with return to ADL 84.6 %(A) vs. 50.1%(B) and recreational activities 73.1 %(A) vs. 43.8 %(B); p<0.05. There was no significant difference in overall satisfaction and pain relief and also in the number of reported complications between Groups A and B (p>0.05).
Conclusion
Patients with BMI > 30 reported higher co-morbidities pre-operatively and less patient satisfaction (return to ADL and recreation) at 3 years when compared to patients with BMI <30. There was no difference in clinical, complications and patient reported outcomes between these groups.
