I have cartilage damage in the ankle joint. What should I do?

What is the osteochondral lestion of the talus (OLTs)?

The OLT is a condition related to local damage to the cartilage and adjacent bone at the dome of the talus in the ankle joint. Although some may be related to growth and developments, most of the OLTs are related to an acute or repetitive injury. Common examples are athletes with multiple ankle injuries that have persistent pain deep inside the ankle joint. This limited damage to the joint, unfortunately, does not heal naturally as it is interfered by joint fluid.

What are the imaging studies need for the diagnosis and treatment of OLTs?

Patients usually have weightbearing x-rays of the ankle joint as the initial study. X-rays may not detect every small cartilage lesions but are good basic investigations to evaluate bone spurs, loose bodies, and arthritis. MRI or CT scans are the gold-standard to visualize the size, shape, and location of the OLTs.

What are the treatments of OLTs?

Some OLTs such as those acute injuries in adolescents can heal using conservative method such as casting. Recent studies have demonstrated the use of artificial joint fluid to control symptoms related to OLTs. Most of the effective treatments are surgical, ranging from minimally invasive methods to large reconstructive surgeries.

Treatmetn options are listed below.

1. Arthroscopic debridement and marrow stimulation

2. Arthroscopic debridement with biologic adjuvants (PRP, Bone marrow aspirate, Cartilage graft, ACI, AMIC, MACI, etc.)

3. Osteochondral autograft transplantation

4. Osteochondral allograft transplantation 

What is the benefits of minimally invasive treatments for OLT?

Minimally invasive treatments for OLTs are listed in #1 and #2 above. They require only arthroscopic portals or mini-incisions without the need for large exposure or taking down of the normal ankle bones. Damaged cartilage and bone is meticulously removed using arthroscopic tools. Cartilage repair is stimulated by creating small holes in the bone at the base of the cartilage lesion. Associated conditions such as bone spurs and loose bodies can be treated at the same time.

Biologic treatments can be added to the arthroscopic procedures if indicated in the same setting.

 

 

What is the postoperative care after minimally invasive treatments for OLT?

Patients can usually do full weightbearing in a boot right away. Ankle motion is encouraged to prevent scar formation. Crutches can be used to assist with walking and fall prevention. 

What can I do if arthroscopic surgery didn't work?

When the cartilage damage is larger than 1-1.5 cm, the risk of failure from arthroscopic procedures increases. In addition, arthroscopic procedures require steep learning curve and an incomplete treatment from a previous surgery is possible. If the lesion is limited in size, a revision arthroscopic treatment is recommended with or without biologic adjuvants. If the lesion is larger than 1.5-2 cm, the patient may benefit from osteochondral autograft transplantation with the donor site at the ipsilateral knee. If the lesion is larger than 2.5 cm, the use of allograft is indicated.
