Intra-articular osteoid osteoma of the lateral tibial plateau treated with arthroscopically assisted removal and retrograde osteochondral grafting.

The treatment of an intra-articular osteoid osteoma is sometimes challenging, because of its location. We report a patient with an intra-articular osteoid osteoma of the lateral tibial plateau which was excised under an arthroscopically assisted procedure. After total resection of the intra-articular osteoid osteoma, the osteochondral defect of the lateral tibial plateau was reconstructed with a retrograde autogenous osteochondral graft which was harvested from the non-weightbearing area of the distal femur.
