Abstract:

BACKGROUND: For the orthopedic surgeon, the postoperative functional recovery after total knee arthroplasty, in which the reconstruction of posterior femoral condylar offset plays an important role, is an important goal.

OBJECTIVE: To understand the anatomic characteristics of the femoral condylar offset and the mechanism how posterior condylar offset influences the functional recovery of knee joint after total knee arthroplasty.
METHODS: The author searched PubMed database and Wanfang database for articles about posterior femoral offset and knee range of motion. The key words were “arthroplasty; replacement; knee; femur; posterior condylar offset; range of motion”. A total of 96 articles were retrieved, and 38 articles met the inclusion criteria.
RESULTS AND CONCLUSION: Posterior condylar offset had differences in gender, ethnics and medial and lateral condyles. To restore the biomechanics of the knee joint, the design of knee prosthesis should consider the difference in genders, ethnics, medial and lateral condyles. The influence mechanism is the “femur-tibia impingement” and “gap balance”. However, further clinical research is needed, for contradictory results regarding whether posterior condylar offset has an effect on knee flexion after total knee arthroplasty.
