Abstract:

PURPROSE: Midterm Functional and Radiological Outcomes of lateral facetectomy with soft tissue correction.

Method

Prospective data of single surgeon series from Nov 2007- Nov 2012 of all patients who underwent a lateral facetectomy with soft tissue reconstruction operation. All patients were seen in a research clinic at final follow up. Radiographs were performed scores were completed by the patient.

Results

A total of 40 patients, 10:25 M:F. 4 were bilateral. Median age 48 yrs(range 20 -65). 37 had PF (OA), 3 had patellar maltracking pain. Median pre and post op scores with ranges were as follows, Lyscholm 42(10-64) to 60 (13-97). SF-12 41(22-56) to 30(16-54). Kujala 42(30-72) to 56(16-88) Bartlett 12(4-22) to 11.5(8-30). Median patellar tilt angles on skyline radiographs pre- post op were 13.520(8.450-25.220) to 13.50(6.450-22.50) and at final xrays’s were 13.1650(80-26.350. The Median gap in the lateral joint space pre, post and final follow up were, 3.5mm(0-5.48mm) , 4.1mm(0-6.52mm) , 3.51mm(0-5.21mm) . ROM was from 80(50-200) of FFD to 900(780-1100) flexion. Clarke’s was positive in 18 and tilt in 20. 8 had scar pain. 6 were converted to PFR, 1to TKR. All but 5 patients were not satisfied with the procedure.

Conclusion

Lateral facetectomy with soft tissue reconstruction operation, in our hands have a poor patient satisfaction and functional outcome results at early to midterm follow up . There is no statistically significant difference noted in the radiological or functional scores. The operation may provide immediate post op relief. The outcomes however are not sustained and remain unsatisfactory.
