There are lots of osteoid tissue and chondral tissue in the tumor.

瘤细胞间见多量骨样组织和软骨样组织。

Objective To study the relationship between patients' age, course of disease, severity of synovial plicae and severity of chondral injuries.

目的研究年龄、病程与滑膜皱襞病变和相应软骨面损伤之间的关系。

Conclusion arthroscopic articular debridement and microfracture was better than arthroscopic articular debridement and washout for treated full-thickness chondral defects.

结论关节镜下关节清理术结合软骨缺损区微骨折术治疗膝关节软骨缺损的疗效优于关节清理灌洗术。

On the contrary, primary malignant maxillary tumor showed invasive growth, irregular bony destruction with massive bony or chondral tumor, periosteal reaction and soft tissue mass.

相反原发性上颌骨恶性肿瘤则呈浸润性生长，骨质不规则破坏，大量瘤骨或瘤软骨形成、骨膜反应和软组织肿块等。

Objective To contrast the treatment effect of full-thickness chondral defects by articular debridement and microfracture and by articular debridement and washout under arthroscope.

目的比较关节镜下关节清理术结合软骨缺损区微骨折术与关节清理灌洗术治疗膝关节软骨全层缺损的临床疗效。

Methods: Nineteen patients with symptomatic chondral and osteochondral lesions of the knee who were treated with fresh osteochondral allografts between 1999 and 2002 were prospectively followed.

方法：从1999到2002年随访了19位接受新鲜骨软骨同种异体骨治疗有症状的膝关节软骨和骨软骨病变的病人，手术时的平均年龄为34岁。

The recent development of surgical and pathophysiologic methods for the treatment of articular cartilage abnormalities has created a need for the accurate, noninvasive evaluation of chondral lesions.

对关节透明软骨缺损有软骨面清理术、软骨下骨穿孔术、软骨移植术和药物治疗，但确定采用那一种方法，需要对软骨状况有个真实的了解。
