Follow-up evaluations were carried out in 84 patients examined 5-8 years after sustaining an acute traumatic hemarthrosis of the knee. The initial examination performed within 2 weeks of injury had revealed 18 patients with a stable knee and 66 with anterior instability. Twelve of the patients underwent anterior cruciate ligament reconstruction within 3 months of injury and 11 more did so between 1 and 3 years after injury. To document joint deterioration at follow-up, bone scintigraphy and conventional anteroposterior, lateral, and tunnel X-rays were taken. Medial, lateral, patellofemoral and patellar uptake in bone scintigraphy was graded from 0 to 4. Six radiological variables were graded at eight different sites. Sixty-three patients (75%) had a positive bone scan and 69 patients (82%) showed radiological changes. Bone scan and X-ray scores were both significantly higher in the reconstructed knees.
对84例膝关节急性创伤性血肿患者进行了5至8年的随访评估。受伤后2周内进行的初次检查发现，18例患者膝关节稳定，66例存在前向不稳定。其中12例患者在受伤后3个月内接受了前交叉韧带重建，另有11例在受伤后1至3年接受了该手术。为记录随访时的关节退变情况，进行了骨闪烁扫描以及常规的前后位、侧位和隧道位X线检查。骨闪烁扫描中内侧、外侧、髌股关节和髌骨的摄取情况从0至4级进行分级。在八个不同部位对六个放射学变量进行了分级。63例患者（75%）骨扫描呈阳性，69例患者（82%）出现放射学改变。重建膝关节的骨扫描和X线评分均显著更高。
