"False patellar duplication" is a situation where there are two pieces in the position of a knee-joint like patella. It can derive from cartilage tumors, soft tissue tumors, or gout tumors, or due to the heterotopic ossification, forming a sub patella in the knee joint.
A woman, 57 years old, healthy history, she has hospitalized for right knee joint pain since 2 years. Diagnosis: the synovial osteochondromatosis of the right knee. We decided to conduct and arthroscopy and removal. After 18 months surgery, the patient knee joint is currently good, range of motion (ROM) (-10)°- 0°-160°, Lysholm Knee Scoring Scale 85/100 point.
This is the second case in the world and the first case in Vietnam. This is an experience in the process of diagnosis, arthroscopic treatment and differentiation from the "double patellae" status.
“假髌骨骶复”是指在膝关节处类似髌骨的位置出现两块骨头的情况。它可能源于软骨肿瘤、软组织肿瘤或痛风肿瘤，也可能是由于异位骨化，在膝关节内形成了髌下骨。
一名57岁女性，健康状况良好，2年来因右膝关节疼痛住院。诊断：右膝关节滑膜骨软骨瘤病。我们决定进行关节镜检查并切除。手术后18个月，患者膝关节目前状况良好，活动范围（ROM）为（-10）°-0°-160°，Lysholm膝关节评分量表为85/100分。
这是世界上第二例，越南第一例。这是在诊断、关节镜治疗以及与“双髌骨”状态鉴别过程中的一次经验。
