Joint Preservation Strategies for Managing Varus Ankle Deformities

Area of Science:

• Orthopedic Surgery
• Biomechanical Engineering

Background:

• Medial ankle osteoarthritis (OA) due to varus deformity often requires joint-preserving interventions.
• Early and midstage OA can be managed with strategies aimed at restoring biomechanical alignment.

Purpose of the Study:

• To evaluate the efficacy of joint-preserving strategies in managing medial ankle OA with varus deformity.
• To highlight the importance of osseous balancing and osteotomies for restoring ankle mechanics.

Main Methods:

• Surgical correction involving osteotomies for osseous balancing.
• Restoration of hindfoot alignment to normalize joint load.
• Comprehensive assessment of underlying etiological factors for varus deformity.

Main Results:

• Substantial postoperative pain relief and functional improvement observed.
• Slowing of the degenerative process in the medial ankle joint.
• While talar tilt may not be fully corrected, significant benefits are achieved.

Conclusions:

• Joint-preserving strategies, particularly osseous balancing via osteotomies, are successful in treating early to midstage medial ankle OA.
• Understanding and addressing the root causes of varus deformity is crucial for successful surgical outcomes.
• Restoring hindfoot alignment is key to normalizing joint mechanics and load distribution.
