Brief Summary

The aim of this study is to evaluate the posterior condylar angle of the distal femur in Turkish population and its concordance with the current standard prosthesis designs used in total knee arthroplasty and to evaluate anthropometric features of the distal femur in the Turkish population.

Conditions

Healthy

Keywords

posterior condylar angle; total knee arthroplasty; external rotation; anthropometric measurements; 3 degrees; Turkish population

Outcome Measures

Primary Outcomes (1)

• condylar twist angle and posterior condylar angle

  The condylar twist angle (CTA) is an angle between anatomical transepicondylar axis (TEA),which lying from medial epicondyle to lateral epicondyle of the distal femur, and posterior condylar axis (PCAx). The posterior condylar angle (PCA) is an angle between surgical TEA, which lying from medial epicondylar sulcus to lateral epicondyle, and PCAx\[1\].

  about 5 days

Secondary Outcomes (4)

• mediolateral lenght of the distal femur (fML)

  about 5 days

• medial anteroposterior lengt (fMAP) and lateral anteroposterior lengt (fLAP)

  about 5 days

• Distance between trochlear groove and fMAP (DBTG-fMAP) and distance between trochlear groove and lateral fAP(DBTG- fLAP)

  about 5 days

• Medial and lateral posterior condylar cartilage thicknesses (MPCCT/LPCCT)

  about 5 day

Eligibility Criteria

• Age: 18 Years - 70 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample
