Summary

This comprehensive scientific research will investigate the influence of the weight-bearing mechanical axis on foot and ankle following total knee arthroplasty. Few studies have monitored the outcome of surgical treatment using similair methods, and consequently the aim of this study was to evaluate the change in upper and lower leg load by analyzing radiographic recordings and pedobarographic measurements after the implantation of total knee endoprosthesis. In addition to objective instruments, knee and foot questionnaires will be used to describe the functional outcome of the operation of the subjects. The practical contribution of this research lies in the prediction of possible changes in the joints of the feet depending on the type of knee deformity (varus / valgus). Our research will consist of: analysis of postero-anterior radiographs of the lower extremity (weight-bearing) preoperatively and at the follow-up three months postoperatively, pedobarographic analyzes preoperatively and at the control examination three months postoperatively, analysis of personal data (age, gender, weight and height, operated side) and completion of functional standardized questionnaires (AOFAS, KOOS) preoperatively, and at the screening three months postoperatively.
