Current Concepts in Clinical Treatment of Osteochondral Lesions of the Talus

Abstract

Osteochondral lesions of the talus (OLTs) are common reason for the deep ankle pain and seriously affect patient’s sports and the daily life. Managements of the OLTs including conservative treatment, cartilage repair surgery, cartilage replacement surgery and cartilage regeneration surgery. For asymptomatic, serendipitous, or acute OLTs with no displaced fragments, conservative treating is suitable to execute, including mainly including affected ankle immobilization with or without physical therapy, bone stimulation, or drugs used. For small OLTs, cartilage repair strategy like bone marrow stimulation technique (BMS) was recommended, and microfracture is the most commonly used surgical procedure. For larger OLTs, both cartilage replacement and cartilage regeneration could be considered including. Although there are many treatment options, each treatment option may have certain limitations and may not be applicable. With the continuous development of science and technology, the development of biological adjuvants and tissue engineering technology has been accelerated and promoted. The combined application of surgery and biological adjuvants and tissue engineering technology has gradually become a hot spot in clinical research. This work briefly introduced present strategies and advance in treatment of OLTs and discussed the potential application problems aiming to provide reference for the future treatment selection and research of OLTs.
