Meniscus Injury
Conditions
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Meniscus injury site | During operation | Observe the meniscus injury site during the operation, which is divided into: medial and lateral anterior horn, medial and lateral body, medial and lateral posterior horn, medial and lateral disc. |
| Types of Meniscus Injury | During operation | The types of meniscus injuries were observed during the operation, which were divided into longitudinal fissure, oblique fissure, spallation, radial fissure, and barrel shank tear. |
| Meniscus surgery method | During operation | Meniscus surgery methods include: partial resection, subtotal resection, total resection, and suture. |
| Cartilage damage | During operation | The cartilage damage is evaluated as yes or no, where the cartilage surface is smooth and complete is defined as no, and the rest is defined as yes. |
| Meniscus regeneration | 7 years after surgery | Second-look after operation to observe whether the meniscus is regenerating. The Meniscus regeneration is evaluated as yes or no, in which the meniscus shape is complete and no tear is defined as yes, and other conditions are defined as no. |
