Abstract
Safety and efficacy of unicompartmental knee arthroplasty UKA has been shown in large patient series Patellofemoral replacement PFR is known to be a viable solution to endstage patellofemoral arthritis Bicompartmental osteoarthritis OA affecting the medial tibiofemoral and the patellofemoral compartment mediopatellofemoral OA is often treated with total knee arthroplasty TKA It was hypothesized that mediopatellofemoral OA can successfully be treated with bicompartmental arthroplastyIn a retrospective approach nine patients who had received UKA in combination with PFR were included into the study Intact ACL and lateral compartment were conditions for the indication Patients were clinically examined including clinical scores KSS and WOMAC and radiographies were evaluated Satisfaction of patients was recorded under four categoriesAverage followup after bicompartmental arthroplasty was 118 ± 54 years 4–17 years Among the nine patients there were eight females and one male at an average age at operation of 64 ± 5 years No surgical revisions were required following bicompartmental arthroplasty The KSS score increased from a preoperative 688 ± 262 to 1755 ± 229 at latest followup p = 0002 WOMAC was 183 ± 86 at latest followup All patients included were satisfied n = 3 or very satisfied n = 6 with the outcome of this surgical procedure
