Chondroblastoma of the patella, rare occurred in patellar,is a kind of an uncommon benign bone tumor. Compared with giant cell tumor, the morbidity of chondroblastoma is lower. Meanwhile, its clinical manifestations are various, and images are very complicated. Therefore, the understanding of this kind of tumors may be limited even to the orthopedist. The differences of patellar chondroblastoma between other tumor in X-ray, CT and MRI is a spot in recent years. Sometimes patellar chondroblastoma coexists with aneurysmal bone cyst, which is a challenge to obtain an accurate pathological and radiological diagnosis. For the treatment, curettage and bone grafting is one the most popular method, but whether to perform a biopsy before surgery still remain controversy. Some new technique still has an unknown prospect for the treatment such as radiofrequency ablation.
髌骨软骨母细胞瘤罕见于髌骨，是一种不常见的良性骨肿瘤。与骨巨细胞瘤相比，软骨母细胞瘤的发病率较低。同时，其临床表现多样，影像学表现非常复杂。因此，即使是骨科医生对这类肿瘤的认识也可能有限。髌骨软骨母细胞瘤在X线、CT和MRI上与其他肿瘤的差异是近年来的一个研究点。有时髌骨软骨母细胞瘤与骨囊肿并存，这对获得准确的病理和放射学诊断构成挑战。对于治疗，刮除植骨是最常用的方法之一，但术前是否进行活检仍存在争议。一些新技术如射频消融在治疗方面的前景尚不明朗。
