Summary
Total ankle replacement is a viable option for end-stage ankle osteoarthritis (OA). This review compares biomechanics and clinical outcomes of mobile- vs. fixed-bearing prostheses for ankle OA treatment.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Sports Medicine
Background:
- Ankle osteoarthritis (OA) affects approximately 1% of the global adult population.
- Total ankle replacement (TAR) has advanced, challenging ankle fusion as the primary treatment for end-stage OA.
- Numerous ankle prostheses are available, necessitating a review of their performance.
Purpose of the Study:
- To review in vitro studies on the biomechanics and kinematics of total ankle prostheses.
- To systematically compare clinical outcomes, including prosthesis survivorship and range of motion, between mobile-bearing and fixed-bearing TARs.
Main Methods:
- In vitro biomechanical and kinematic analysis of ankle prostheses.
- Systematic literature review of clinical outcomes for mobile- and fixed-bearing total ankle prostheses.
Main Results:
- Review of in vitro studies on biomechanics and kinematics of replaced ankles.
- Assessment of clinical outcomes, including prosthesis survivorship and postoperative range of motion.
- Comparison between mobile- and fixed-bearing total ankle prostheses.
Conclusions:
- Total ankle replacement is a significant therapeutic option for end-stage ankle osteoarthritis.
- Further research comparing mobile- and fixed-bearing prostheses is crucial for optimizing patient outcomes.
- Understanding biomechanics and kinematics aids in prosthesis design and selection.

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
