Ankle Joint

Ankle 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...

Functional Classification of Joints

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Summary

Total ankle replacement (TAR) can successfully correct severe coronal deformities greater than 10° when combined with necessary associated procedures. Careful surgical planning and execution are key for durable outcomes in these complex cases.

Treatment of Ankle Osteoarthritis with Total Ankle Replacement Through a Lateral Transfibular Approach

Area of Science:

Orthopedic surgery
Biomechanical engineering
Podiatric medicine

Background:

Total ankle replacement (TAR) outcomes for arthritis with coronal plane deformities lack consensus.
Determining technical requirements and adjunctive procedures is crucial for successful TAR in these cases.

Purpose of the Study:

To evaluate clinical and radiographic outcomes of TAR in patients with coronal plane deformities exceeding 10°.
To identify essential technical requirements and additional procedures for optimal TAR results in complex deformities.

Main Methods:

Retrospective review of 21 total ankle replacements (TAR) in patients with coronal deformities >10°.
Exclusion of inflammatory arthritis; inclusion of osteoarthritis secondary to fracture or instability.
Categorization by ankle congruency (congruent/incongruent) and deformity type (varus/valgus); assessment of associated procedures and follow-up outcomes.

Main Results:

Significant improvement in functional outcomes and deformity correction (varus: 16.5° to 2.5°; valgus: 16.7° to 1.4°).
Six varus ankles required revision for further correction; three incongruent ankles failed.
Short-term results demonstrated satisfactory correction even in severe deformities.

Conclusions:

Correction of osteoarticular and ligamentous deformities necessitates numerous associated procedures for successful TAR.
Addressing residual defects is vital for implant longevity and warrants further intervention.
While short-term results are promising, long-term monitoring is essential for severe deformities treated with TAR.
