Osteochondral Lesion of the Talus (OLT)

An OLT is localized damage involving both the articular cartilage and the underlying bone on the top surface of the talus (ankle bone).

Symptoms

• Deep, aching ankle joint pain (worse with weight-bearing)
• Persistent swelling and stiffness
• Catching, locking, or clicking sensations during movement

Causes

OLTs are most commonly caused by traumatic ankle injuries—such as severe sprains or fractures—that compress or shear the joint cartilage.

Risk Factors

• History of recurrent ankle sprains
• Chronic ankle instability
• Participation in high-impact or pivot-heavy sports

Diagnosis

Our specialists combine physical examinations with targeted imaging—using X-rays to check joint structure and an MRI to accurately measure the lesion's size, depth, and stability.

Treatment

Initial care involves non-surgical management like rest, bracing, and targeted physical therapy. For persistent or severe cases, Premier Orthopaedics offers advanced minimally invasive arthroscopic surgery and tissue restoration procedures.
