An accessory iliotibial band insertion: a unique anatomical variant.

The iliotibial band (ITB) is considered an important anterolateral knee joint stabiliser. Its exact anatomy remains unclear with inconsistency owing to relative paucity of detailed cadaveric studies. Multiple ITB distal insertional sites have been reported, the most common and well known being a direct attachment onto Gerdy's tubercle of the anterolateral tibia.

Gout-mimicking sarcoma recurrence at a prosthesis bone interface remote from any joint.

Gout is known to occur in a variety of organs but most commonly presents as an inflammatory arthropathy. A few reported cases have documented its occurrence in prosthetic neo-joints or juxta-articular to this. We present the first reported case at a bone prosthesis interface remote from any joint and mimicking sarcoma recurrence because of its unusual location.
