Sampling method: PROBABILITY_SAMPLE
Study population: 8778 patients with meniscus injury who underwent surgery at the Institute of Sports Medicine of the Third Hospital of Peking University before December 31, 2008 and patients who underwent meniscus suture, partial resection, subtotal resection, or total resection afterwards

Brief summary: Through the analysis of the data of 8094 patients with knee meniscus injury before December 31, 2008 and more patients with partial meniscus resection, subtotal resection and total resection, we can understand the gender difference and ratio of medial and lateral meniscus injuries. Differences, differences in locations, differences in tearing methods, differences in surgical methods, and the course of the disease affect the meniscus injury and surgical methods, and further affect the patient's knee degeneration imaging, accompanying cartilage injury, knee osteoarthritis, Partial resection, subtotal resection and meniscus regeneration after total resection, imaging and secondary arthroscopic exploration (Second-Look) were studied.

Detailed description: Through the data of 8094 patients with knee meniscus injury who underwent surgery at the Institute of Sports Medicine of the Third Hospital of Beijing Medical University before December 31, 2008, and the patients who underwent meniscus suture, partial resection, subtotal resection, and total resection. Analyze and understand the influence of gender difference, ratio difference, position difference, tearing method difference, surgical method difference and disease course on the meniscus injury situation and operation method of the internal and lateral meniscus injury. Observation and research will also be conducted on reports of knee cartilage injury, knee osteoarthritis, and meniscus regeneration after partial meniscus resection, subtotal resection and total resection.
