Clinical Results of Antero-medial Displacement of Tibial Tuberosity for Patello-femoral Arthrosis

Abstract

Antero-medial displacement of tibial tuberosity was done on 2 2 knees with patellofemoral arthrosis of 17 patients (one man and 16 women, with ages ranging from 47 to 65, averaging 53.4) . Follow-up periods ranged from 2 to 13.1 years, 5.3 on an average.
Pain on going down stairs was noted in 22 knees and was relieved in 20 postoperatively. Retro -patellar crepitation also was relieved in 3 of 21, patellar pain on grating in 17 of 19, tenderness around the patella in 15 of 17, pain on passive motion of the patella in all of 19, and extension pain on holding the patella in place 11 of 12. The patellar subluxation was observed to be repositioned in the sky-line view in all knees. Patella baja was seen postoperatively in most cases, measured from the lateral view by the Insall-Salvati method.
