Endoscopic marginal excision of extraarticular osteochondroma around the knee

We present three patients with pedunculated and sessile osteochondromas of distal femur and proximal tibia, ranging from a 15-year-old to a 30-year-old patient. All were removed due to esthetic concerns; therefore, we utilized a novel marginal excision using minimally invasive endoscopic tools. All patients had excellent functional and esthetic outcomes up until 1-year postoperative evaluation. Although technically challenging, endoscopic marginal excision is a viable alternative for the surgical management of osteochondroma of the knee and should be considered when esthetic is the primary concern of the patients.
