A symptomatic osteochondral lesion (OCL) greater than 8-10 mm. Authors vary on which size need to be treated with an ostechondral graft. With a smaller OCL, debridement is best.
X-rays and an MRI should be taken.
Step by step description to illustrate surgical technique
Pearls and Pitfalls
Obtaining proper alignment of graft so excellent congruency is achieved is of the utmost importance.
Include immediate postoperative care and rehabilitation
Include functional and prosthetic survivorship data as applicable
A possible complication is adjacent cyst formation in the talus probably due to inadaquate cartilage growth. Results can possibly be mitigated by obtaining best fit and through the use of PRP or BMAC. Fixation of the medial malleolar osteotomy to achieve anatomic reduction and avoid proximal migration is very important.
