The aim of the study is to investigate the correlation between arthroscopic findings and joint space width on the standing knee radiographs at various flexion degrees in the young- and middle-aged patients with complaints of knee pain.
Middle-aged patients with complaint of knee pain ongoing more than 6 months and failure in conservative treatment methods were included. Weight-bearing full extension, 30 and 45° of flexion radiographs were obtained. Joint space width was calculated on radiograms. Arthroscopy was performed to evaluate the chondral pathologies. Correlation analysis was performed.
Fourty-three patients (18 female, 25 male) with a mean age of 44.6 (20-63) were included. Mean joint space width was 4.87 mm ± 1.45 (2-10) mm in medial and 5.43 mm ± 1.47 (1-9) in lateral on standing extension radiographs. In 30° flexion radiographs, mean joint space width was 4.33 mm ± 1.25 (1.5-7.5) in medial and 5.36 mm ± 1.69 (1-9) in lateral. In 45° flexion radiographs, medial joint space was 4.28 mm ± 1.59 (2-9) in medial and 5.15 mm ± 1.59 (1.5-9) in lateral. In arthroscopic evaluation, one knee had grade 1 (2.3%), three knees had grade 2 (7%), nine knees had grade 3 (20.9%), and twelve knees had grade 4 (27.9%) lesions in the medial compartment. In the lateral compartment, two knees had grade 3 (4.7%) and one knee had grade 4 lesion (2.3%). Radiological data did not correlate with the arthroscopic findings.
Standing knee radiographs do not correlate with the arthroscopic findings in the middle-aged population with chondral lesions in knee joint.

本研究旨在探讨中青年膝关节疼痛患者在不同屈伸位站立位膝关节 X 线片上的关节间隙宽度与关节镜检查结果之间的相关性。
纳入膝关节疼痛持续 6 个月以上且保守治疗失败的中年患者。获得负重完全伸展位、30°和 45°屈曲位的 X 线片。在 X 线片上计算关节间隙宽度。进行关节镜检查以评估软骨病变。进行相关分析。
共纳入 43 例患者(18 名女性,25 名男性),平均年龄为 44.6(20-63)岁。站立伸展位 X 线片上,内侧平均关节间隙宽度为 4.87mm±1.45mm(2-10mm),外侧为 5.43mm±1.47mm(1-9mm)。在 30°屈曲位 X 线片上,内侧平均关节间隙宽度为 4.33mm±1.25mm(1.5-7.5mm),外侧为 5.36mm±1.69mm(1-9mm)。在 45°屈曲位 X 线片上,内侧关节间隙为 4.28mm±1.59mm(2-9mm),外侧为 5.15mm±1.59mm(1.5-9mm)。关节镜评估中,内侧间室 1 膝为 1 级(2.3%),3 膝为 2 级(7%),9 膝为 3 级(20.9%),12 膝为 4 级(27.9%)病变。外侧间室 2 膝为 3 级(4.7%),1 膝为 4 级病变(2.3%)。影像学数据与关节镜检查结果无相关性。
在膝关节软骨病变的中年人群中,站立位膝关节 X 线片与关节镜检查结果不相关。
