Study 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.

Accepts healthy volunteers
No

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

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

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 or chemotherapy treatment,
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Study arms

  • Active comparator
    Retro-articular drilling

    Retro-articular drilling goes through the cortical margin of the affected condyle, thereby sparing the articular surface and physes.

    Procedure: Retro-articular drilling

  • Active comparator
    Trans-articular drilling

    Trans-articular drilling penetrates the articular cartilage through multiple sites to create subchondral penetrations.

    Procedure: Trans-articular drilling

Interventions

  • ProcedureRetro-articular drilling

    * 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.

    Also known as: antero-grade, extra-articular

  • ProcedureTrans-articular drilling

    * 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

    Also known as: antero-grade, extra-articular

What researchers measure

Primary outcomes

  1. Physical functioning measured by the Pedi-IKDC (International Knee Documentation Committee) total score

    Time frame: One year post-surgery

Secondary outcomes

  1. Activity level as measured by the Marx Activity Scale

    Time frame: One year post-surgery

  2. Physical functioning as measured by the Pedi-IKDC total score

    Time frame: Two years post-surgery

  3. Time to lesion healing

    Lesion healing will be assessed by x-ray at multiple time points

    Time frame: 3 months to 2 years post-surgery

Other outcomes

  1. Surgical complications

    Inadvertent displacement of OCD fragment; damage to articular cartilage and physes

    Time frame: 1 week to 1 year post-surgery

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 3, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
