Osteotomia valgaderrotativa del genoll per a la correcció del morfotip torsional convergent

by Gasch Blasi, Jordi

Abstract (Summary)
INTRODUCTION Oblique plane osteotomy of the knee allows correction of associated angular and torsional deformity by a single bone section. The purpose of this study is to analise the results of this surgical procedure with statistical analysis, find the predictors factors, and the tipology of the patients. On the other hand, want to find the mathematical formulation in order to correct the torsional and angular deformity. MATERIAL AND METHODS The study was performed during the period 1984-1995. The series comprises 57 patients, 21 females and 36 males. The sintomathology was noted in relation to patellofemoral pain in 33 cases, pain in the medial compartment of the knee in 20, big deformity in 4 and patellar subluxation in 1.The meadle age of the patient in the operation was of 28 years and nobody of them had previous surgical procedures, clinical or radiologic arthrosis. Qualitative and quantitative data were quantified by clinical explorations and mesuring torsional and radiological angles. The follow up was 8.2 years. RESULTS The Lysholm score was 66 points before surgery and 93 after. Medial satisfaction for the patients was about 8.5 points. We have seen the lost of degrees in TAGT, lateral tibial torsion and femorotibial correction (anatomical and mecanical axes). After surgery, frontal angles lost some degrees but without clinicals problems. We have seen that there are some variables associateds with good results for example male sex, no patellofemoral pain, femoral dysplasia and more age. If the intervention is done with high level of pain, the results are better and if there is arthritis long time after the surgery the results are worse. DISCUSION This surgical procedure allows correct angular and torsional deformity with a emprove of knee pain in most of the cases. There are no changes in the "step angulation" don' t change because hip rotation compensates this. The patellar bascula and the external subluxation lost is allowed performing the Ficat procedure and the growing of recurvatum by the lost of tibial angulation of the base.
