补充资料：髌骨软骨软化症
| 髌骨软骨软化症 chondromalaciapatellae 髌骨软骨面纤维化、碎裂又脱落等退行性变化引起的膝前疼痛症，上下台阶、长期屈膝或下蹲时疼痛加重。此病多从青年开始，女性多于男性，运动员更常见，与髌骨长期反复受到挤压摩擦有关。有的可发展为髌股骨关节病。髌骨轴位（切线位）X射线片及 CT可见关节面狭窄、硬化、髌骨倾斜及半脱位等变化。关节镜有助于早期诊断及手术。此病一般采用非手术疗法，改善膝部活动以减少髌骨软骨的压力及摩擦力 ，理疗及药物可缓解症状 ，有的可进行软骨面刨削、整修或软化病灶剔除、软骨下骨皮质钻孔术。重度髌骨软骨软化症病变范围广泛者可采用髌骨截骨术、髌骨成型术或髌骨切除术。 |
