Osteochondritis dissecans of the patella is a rare cause of anterior knee pain. An illustrative case in a 22-year-old man demonstrates the current imaging modalities and surgical treatment. Specifically, magnetic resonance imaging (MRI) and arthroscopic knee surgery are discussed along with a review of the literature. Unlike standard roentgenograms, MRI can be helpful in determining the viability of the osteochondritic fragment and the amount of remaining attachment to the surrounding cancellous bone. This finding can have important bearing on choice of treatment. When surgery is indicated, arthroscopic treatment with excision of the fragment and curettage offers distinct advantages over open arthrotomy. Lateral release or other realignment procedures may be done in combination with the primary procedure. Prognosis for full recovery of knee function and relief of patellar pain is guarded in patients who require surgery.

We reviewed 13 cases of osteochondritis dissecans of the patella followed-up for 18 months to 19 years. Two were treated conservatively with excellent results, and 11 by operation with six excellent, four good and one fair result. There was complete radiographic healing of the defect in 10 cases and partial healing in three. The size of the osteochondritic lesion appeared to be of prognostic significance. Osteochondritis dissecans of the patella is the result of repeated minor injuries to the articular surface. Operation is indicated for persistent pain, intra-articular loose bodies and subchondral sclerosis; excision of the fragment and curettage of the crater, with or without drilling, is recommended.

Osteochondritis dissecans of the patella in 9 patients (6 men, 3 women; mean age 19 years) was located in the median ridge and paramedial areas and was bilateral in 3 patients. All patients were initially treated conservatively with complete relief of symptoms in 5. In 7 patients fragments were excised and the crater was curetted and drilled. At follow-up after 4 (2-8) years, the patients had no restriction of activities and they had no pain.
