Two kittens aged between four and five months were presented having sustained patellar fractures. In both cases, healing was subsequently documented radiographically; this has not been reported previously in the literature. One kitten had bilateral patellar fractures - the symptomatic right stifle was treated with a pin and tension-band-wire which later failed, at which point partial patellectomy was performed. The fracture of the left patella was minimally displaced and was treated conservatively. A radiograph of the left patella taken eleven months after initial presentation showed complete healing of the fracture. The second case was treated surgically with a circumferential wire; healing of the fracture was demonstrated radiographically at twelve weeks postoperatively. Radiographic images taken five weeks postoperatively had shown some narrowing of the fracture gap. These two cases demonstrate that bony union of patellar fractures can be documented, given a long enough duration of radiographic follow-up; circumferential wire was an effective treatment in a displaced fracture, and conservative treatment resulted in complete healing of a minimally displaced fracture.
两只4到5个月大的小猫出现了髌骨骨折。在这两个病例中，随后通过X光片记录到骨折愈合情况；此前文献中尚未有过此类报道。一只小猫双侧髌骨骨折——有症状的右侧膝关节用钢针和张力带钢丝进行治疗，但后来失败了，此时进行了部分髌骨切除术。左侧髌骨骨折移位极小，采用保守治疗。初次就诊11个月后拍摄的左侧髌骨X光片显示骨折完全愈合。第二例通过环形钢丝进行手术治疗；术后12周的X光片显示骨折愈合。术后5周拍摄的X光片显示骨折间隙略有变窄。这两个病例表明，只要进行足够长时间的X光随访，髌骨骨折的骨愈合情况是可以记录的；环形钢丝对移位骨折是一种有效的治疗方法，保守治疗可使移位极小的骨折完全愈合。
