THE INFLUENCE OF COMPUTER-ASSISTED SURGERY ON CLINICAL AND RADIOGRAPHIC OUTCOMES OF PERIАRTICULAR FEMUR AND TIBIA OSTEOTOMIES IN OSTEOARTHRITIC PATIENTS (REVIEW)

Abstract

Nowadays the clinical application of digital technologies became a growing trend at every stage of orthopedic patient treatment: from diagnostic procedures and pre-operative planning to intra-operative control of surgical manipulations and evaluation of final results later. The aim of thi sresearch was to analyze the studies dedicated to application of computer-assisted surgery (CAS) for femur and tibial osteotomies in patients with gonarthrosis. The hypothesis was that CAS improves the precision of leg alignment correction in frontal and sagittal planes that positively influencing both functional result of treatment and longevity of clinical effect. The PubMed, PubMedCentral, GoogleScholar and eLIBRARY searched for relevant studies using following key words: knee, osteoarthritis, gonarthrosis, osteotomy, CAS, navigation and its russian analogs. The majority of publications favored CAS in comparison to traditional osteotomy techniques both for leg alignment and tibial slope control. Despite generally researchers paid less attention to functional results after CASosteotomies than to precision of surgical manipulations it is possible of confirm that there is strong tendency to better knee scores after navigation while the difference is not always statistically significant. Rare publications dedicated to long term results favor CAS: 10 years survival rate is 97% that correspond to outcomes of modern total knee arthroplasty. Hence, the current literature confirms the hypothesis of our study and don’t reveal increase of complications rate associated with CAS.
