Objectives the objective of our study is a search for personalized coefficient and calculation algorithm for knee joint line (KJL) using unified radiologic criteria. One of the most important criterions of knee total arthroplasty efficiency is the recovery of painless motion range and knee joint stability which is essentially associated with the reconstruction of KJL most closely approximated to its anatomical position. It is worth considering that KJL deviations more then 5 mm following knee joint arthroplasty cause such complications as patellofemoral syndrome with typical presentation of contact chondromalacia patella and decay of movement amplitude.

Methods In the course of retrospective study knee joint radiographs of 202 patients have been analyzed. The patients were 100 women and 102 men aged 45-68 years (mean age is 55.4±1.3 y.o.) all requiring knee joint endoprosthesis replacement. The research was conducted during preoperative stage. The length between the highest points of femoral condyles was measured and then a perpendicular was dropped to the reconstructed knee joint line which was measured as well.

Results and Conclusion the obtained results show the lack of interrelation to both sex and anthropometric measures of patients supporting the available literature data. The limitations of our research should be noted: small numbers of patients in samplings, samplings vary in number, some samplings lack patients’ height data (for men shorter than 160 cm and women taller than 180 cm). The search for reliable personalized criteria is therefore relevant and actual for now.

Defining KJL deviations is essential for revision arthroplasty planning and is one of the success components for biomechanical disorders diagnostics in patients with poor results of the replacement. 202 patients participated in our research, they were divided into groups depending on their sex and height, and we found no significant correlations with either parameter of the patients.
