"Spiking", "sharpening" or "peaking" of the tubercles of the intercondylar eminence of the tibial plateau has been described as an early sign of osteoarthritis of the knee joint, but there are no reports confirming this association. The radiographs of 55 patients with established osteoarthritis of the knee joint and 36 controls were reviewed. Measurements were made of the angulation of the tips of the medial and lateral tubercles, and the ratio of the tubercle height to the width of the tibial plateau was calculated. There was a significant difference in both these parameters between the two groups, confirming that lengthening and sharpening of the angles of the tubercles are features of osteoarthritis of the knee joint.
胫骨平台髁间隆起结节的“尖峰化”“锐化”或“峰值化”已被描述为膝关节骨关节炎的早期征象，但尚无报告证实这种关联。回顾了55例确诊为膝关节骨关节炎患者和36例对照者的X线片。测量了内侧和外侧结节尖端的角度，并计算了结节高度与胫骨平台宽度的比值。两组在这两个参数上均存在显著差异，证实结节角度的延长和锐化是膝关节骨关节炎的特征。
