Description of intervention(s) / exposure
Participants already scheduled fo r knee arthroplasty or tibial osteotomy . Attendance at a 10-minute session involving capture of standardized x-ray , measurement of height and weight, and completion of a questionnaire regarding shoe size, with each component taking approximately 2 minutes to complete.
1 day prior to knee arthroplasty or tibial osteotomy, etc.
Once only examination.
The assessment wil be perfomed by study researcher - orthopaedic surgeon.
Intervention code [1] 319917 0
Diagnosis / Prognosis
Comparator / control treatment
Participants are tested only once because the aim of the study is to try to find a correlation between the height and length of the foot and the length of the tibia and femur. The control group will be volunteer employees of the ward of similar age who will give their consent to the study.

Statistical methods / analysis
The length range of individual parts of the limb will be determined in relation to the height and size of the shoes, along with the standard deviation of the above parameters. We operate on about 400 people a year due to osteoarthritis of the knee, so we should easily gather a group of 200 patients.

Summary
Brief summary
The aim of the study is to measure the length of the tibia and femur and to try to find the correlation of these parameters with height, weight and shoe size. The examination will be performed in connection with the unresolved problem of selecting the appropriate length of the implant that fixes the fracture of the femur or tibia. The possible positive results may contribute to the establishment of new guidelines for preoperative planning in the treatment of long bone fractures with the use of an intramedullary nail.
Therefore, a group of researchers led by prof. dr hab. Dr. Marcin Domzalski, MD, decided to use a radiological examination, which is usually performed before elective surgeries, to trace the length of the tibia and femur, and to find their correlation with the height, weight and shoe size using statistical analysis. The study will cover adults aged 22-90 who agree to participate in the study. It is assumed that the study is to last at least a year, with the possibility of extending the duration of the study.
The study will include patients who have been planned for knee arthroplasty or corrective osteotomy of the femur or tibia and have a standard centimeter-graduated photo.
Patients who do not consent to the study will be excluded from the study.
