Brief summary
The purpose of this study is to compare the functional, clinical and radiographic outcomes associated with trans-articular drilling versus retro-articular drilling, two commonly employed techniques of operative treatment for stable forms of juvenile osteochondritis dissecans (JOCD) lesions. This study also aims to better define the natural history of this condition in its most commonly identified pathological state (as a stable lesion) following surgical intervention by determining the rate of radiographic healing and any need for secondary surgery.
Interventions
* Drilling must be performed under AP and lateral fluoroscopic guidance, with no additional drilling in 'trans-articular', or intra-articular trans-condylar fashion. * Use a 0.045 K-wire for drilling. * Minimum of 8 wire passes per square centimeter with no maximum number of wire passes.
* Drilling must be performed, under arthroscopic visualization, directly through the articular cartilage, with no additional drilling in 'retro-articular', 'extra-articular', or trans-condylar (through the intercondylar notch) * Use a 0.045 K-wire for drilling * A minimum 4 wire passes per square centimeter, with a maximum of 5 wire passes per square centimeter

Eligibility
Inclusion criteria
* Diagnosis of JOCD, * Lesion located on the lateral aspect of the medial femoral condyle, * Lesion considered stable based on MRI, * Patient deemed skeletally immature based on MRI, * Completed a course of conservative therapy.
Exclusion criteria
* Significant concomitant knee pathology (AVN, fracture, inflammatory arthritis, ACL tear, discoid/meniscal tear, etc.) * Lesion healed sufficiently and surgery is not recommended, * Prior surgery on the affected knee, * Diagnosis of metabolic bone disorder (e.g. osteogenesis imperfecta), * Diagnosis of sickle cell disease, * History of prolonged corticosteroid or chemotherapy treatment,
