Functional outcome following modified Elmslie-Trillat procedure.
The aim of this study was to evaluate the mid- and long-term outcome of the modified Elmslie-Trillat procedure, as well as to detect factors affecting it. Thirty-eight patients (44 procedures) with a mean age of 31 years were included in this study. The reason for operation was patellar instability in 10 cases, anterior knee pain with malalignment of the extensor mechanism in 15 cases and a combination of both in 19 cases. Patients were followed for an average of 40 months (range=18-130 months). The functional outcome was very satisfactory or satisfactory for 73% of patients. According to Cox's criteria it was excellent in 13 cases (30%), good in 18 (41%), fair in 7 (16%) and poor in the remaining 6 (13%). Patients scored an average of 3.5 (range=2-8) in their Tegner Activity Scale, while their score in Activities of Daily Living Scale of the Knee Outcome Survey ranged from 43 to 98 (average=76). Result analysis revealed a better functional outcome when the operation was performed for patellar instability, as well as in the absence of grade 3 or 4 chondral changes in the patellofemoral joint at the time of operation. Elmslie-Trillat procedure satisfactorily restores patellofemoral stability and offers a very good functional outcome, especially in the absence of significant chondral changes in the patellofemoral joint at the time of operation.
