The lateral condyle groove at the elbow includes the capitellotrochlear groove and the lateral aspect of the olecranon fossa, where the lateral elbow joint space is accessed arthroscopically via the anterolateral portal.
The lateral condyle groove space is the primary target in elbow arthroscopy for loose body removal, osteochondral defect treatment, and lateral epicondyle debridement. The radiocapitellar joint is assessed in this space. Posterior interosseous nerve proximity to the lateral arthroscopic portal requires careful portal placement to avoid nerve injury.
