Objective. The knee ligaments, as a passive knee joint stability device, provide protection for the knee joint and ensure its functional integrity. This role has long been known and recognized by people. The original purpose of knee ligament reconstruction after knee ligament injury is to restore its anatomical structure and mechanical stability mechanism. Methods. Taking athletes as the research object, randomized controlled trials (RCTs) on improving ankle joint function of athletes related to proprioception training at home and abroad were included. The search time was from the establishment of the database to December 31, 2019, and the references of related documents were traced. Two researchers independently screened the literature, extracted data, and evaluated the quality of the literature. RevMan 5.3 software was used for data analysis. Results. The extensor strength, flexor strength, and flexor strength/extensor strength of the affected limb were higher than before the operation one year after surgery ( P < 0.01 ). The Lysholm score, Lysholm instability score, and one-foot jump distance were all higher than those before surgery ( P < 0.05 ); the difference of KT-2000 for both knees was smaller than that before surgery ( P < 0.05 ). Conclusion. In maintaining the anterior stability of the knee joint, the knee ligament provides 85% static resistance to prevent the tibia from moving forward, so knee ligament injury will cause knee instability. The proprioceptive feedback mechanism plays an important role in maintaining the functional stability of joints.

Objective. The shoulder joint is the most flexible joint in the human body. It is a typical multiaxial ball-and-socket joint. The humeral head is approximately spherical, and the glenoid is small and shallow. This article mainly discusses the application value of computerized tomography (CT) in the early diagnosis of skeletal Bankart injury of the shoulder joint. Methods. The chemical quality was evaluated according to the physical therapy evidence database PEDro scale. The literature quality evaluation scale and the NO scale are also used to evaluate the quality of each nonrandomized study. The standard quality scores of the literature quality evaluation scale are as follows: (1) the selection of the study group; (2) the comparability of the study group; and (3) (cohort study) clear interest results. Outcome measurement: Postoperative shoulder joint stability and range of motion (ROM) are the main results of Bankart injury patients undergoing open repair surgery and arthroscopic repair surgery. The secondary results of the survey included the Rowe score, the shoulder stability score, the American shoulder and elbow surgery score ASES, the University of California, Los Angeles, shoulder score UCLA, and the operation time. Results. Four of the included studies are randomized controlled trials, and the other studies are cohort studies. After meta-analysis, a fixed-effect model ( I 2 = 34 % ) was used to observe the difference in shoulder stability treatment between the two groups and was statistically significant ( P = 0.008 , RR = 0.94 , 95% confidence interval: 0.89~0.98). The analysis results showed that compared with patients undergoing open surgery, patients’ undergoing arthroscopic repair had better postoperative shoulder motion range ( P < 0.001 , SMD = 0.47 , 95% confidence interval: -0.72~0.22), and there is no significant heterogeneity. Conclusion. The Bankart injury of the shoulder joint cannot be diagnosed by X-ray examination alone due to its anatomical location and the size of the fracture fragments. CT examination has a better auxiliary diagnostic effect in the early stage of skeletal Bankart injury.
