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...

Total ankle replacement (TAR) effectively corrects significant varus deformities in the ankle, maintaining alignment long-term. This study demonstrates successful outcomes for ankle arthroplasty in managing these complex frontal plane issues.

Area of Science:

Orthopedic Surgery
Biomechanical Engineering

Background:

Ankle varus treatment with total ankle replacement (TAR) lacks established deformity limits.
Anatomic prosthetic designs and comprehensive surgical techniques improve frontal plane deformity management.

Purpose of the Study:

Evaluate outcomes of TAR for large frontal plane varus deformities.
Compare correction using two different TAR systems.
Determine a stepwise surgical approach for consistent deformity correction.

Main Methods:

Retrospective study of 26 patients with varus ankle deformity (mean age 63.85 years).
TAR performed using two distinct replacement systems.
Radiographic alignment assessed preoperatively and postoperatively (mean follow-up 16.69 months).

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

Published on: January 24, 2018

Main Results:

Preoperative mean varus deformity of 16.8° corrected to 0° (AP view) and 0.5° (mortise view) postoperatively (P < .0001).
Correction was maintained at final follow-up for all but one patient.
All patients achieved correction within 4° of frontal plane neutral.

Conclusions:

Total ankle replacement is a successful surgical option for correcting varus ankle arthrosis.
Consistent correction of significant frontal plane deformities is achievable with TAR.
Established surgical approaches can maintain correction throughout the study period.
