We read with interest the article entitled, “Risk factors and impairments in iliotibial band friction syndrome among basketball players” by Panse et al. The article highlights the disability caused by iliotibial band friction syndrome (ITBFS) and factors compounding the problem such as rigorous knee movements, footwear, running surfaces, and training errors among others. The morphological characteristics such as internal rotation of tibia and hip abductor weakness are other causes well mentioned in the article. We have no direct comment on the article, but we would like to state that very rarely, anatomical disorders around knee may cause ITBFS as a late presentation as depicted by a short case snippet though not in a basketball player.
A 26-year-old cyclist presented to us with disability to ride for long for apprehension of knee pain, loud snapping, and fear of tendon rupture. There was a history of bony growth over the lateral aspect of the left knee from adolescence that stopped growing after puberty. The lump did not cause any significant problem in the past but for the last 7 months, the movement of tendons across the hard lump was clinically noticeable and audible as snapping [Figure 1]. There is also acute pain on extreme knee movements in extension more than flexion periodically. The radiograph of the knee revealed a lateral distal femur sessile bony growth, suggestive of a bony exostosis or solitary osteochondroma [Figure 2]a. After informed consent, the excision of the exostosis was done as per the standard protocol with histopathological confirmation [Figure 2]b. There were marked clinical relief and functional improvement. There was no recurrence or remarkable complication noted in the follow-up.

Osteocartilaginous exostosis or osteochondroma is the most common benign bone lesion cartilage capped and mostly solitary. Mechanical effects are common and the presentation is varied depending on the type of structure involved. There are reports of snapping of the knee due to irritation of lateral tendons such as biceps femoris over fibular or medial hamstring by tibial exostoses. Very rarely, the sharp and pointed end of some exostoses, also referred as “thorny exostoses,” may cause localized impingement around knee. As exostoses are common clinical disorders, knowledge of their uncommon presentations, variants, and sites should be critical in prompt diagnosis and management. Our case describes an uncommon location and presentation and thus has educative potential.
