Abstract:

BACKGROUND: Gait analysis is a special subdiscipline in the field of biomechanics and has been widely used to evaluate the effects of gait disorders and orthopedic surgery. There is a lack of gait analysis in the diagnosis of anterior cruciate ligament injury.
OBJECTIVE: To investigate the application value of gait analysis in the diagnosis of anterior cruciate ligament injury.
METHODS: The study was in accordance with the ethical requirements of Guizhou Orthopedics Hospital, and the patients and their families signed the informed consents. Sixty patients with anterior cruciate ligament injury diagnosed by arthroscopic surgery were selected. The infrared optical navigation knee motion analysis system, gait analysis, and physical examination were performed to explore their diagnostic values of anterior cruciate ligament injury.
RESULTS AND CONCLUSION: (1) The results showed that gait analysis (n=49) was superior to physical examination (n=29) and magnetic resonance imaging (n=35) in the diagnosis of anterior cruciate ligament injury (P < 0.05), especially in patients with mild anterior cruciate ligament injury (P < 0.05). There was no significant difference in moderate and severe anterior cruciate ligament injuries (P > 0.05). (2) Comparison between gait analysis and magnetic resonance examination showed that the area under the curve of ROC was 0.636 4 (95% confidence interval, 0.535 9-0.736 8, P=0.010). Comparison between gait analysis and physical examination, the area under the curve of ROC was 0.620 3 (95% confidence interval, 0.519 4-0.721 1, P=0.023 0). (3) In summary, gait analysis under optical navigation is another effective method for diagnosing anterior cruciate ligament injury.

Key words: gait analysis, anterior cruciate ligament injury, knee joint physical examination, magnetic resonance examination, accuracy diagnosis
