Introduction: Osteochondroma is a type of tumor that is not very common, and about 30% of these tumors are found in the lower part of the thigh bone. Most of these cases de not cause any symptoms, but when they do, surgery might be needed. This study aims to describe the clinical features and treatment results for people who had a single, painful bone growth near a knee joint.

Methods: This was an observational descriptive bicentric study over 12 years (January 2012 to December 2023) carried out in the department of orthopaedic and traumatology surgery of Cocody and Bouaké. Patients presented with knee pain in all cases. Radiographs confirmed the presence of a para-articular bony growth. The data studied were clinical and therapeutic results.

Result: There were 11 patients, including 9 men and 2 women, with an average age of 18.7 years (range, 10-35). Para-articular bony growth either sessile (n=9) or pedunculated (n=2). The average size of the growth was 3.6 cm (range, 4-6), with an average thickness of 0.9 cm (range, 1.3-2.1). All patients underwent surgical excision of the growth, and histopathology confirmed the diagnosis of solitary osteochondroma. No postoperative complications or recurrences were observed at an average follow-up of 37.5 months (range, 14-79). Post-treatment, the average Lysholm knee score was 98.2 (range, 97-100).

Conclusion: This study shows that surgery is an effective way to treat this type of tumor. The lack of recurrence and good function after treatment support this conclusion.
