INTRODUCTION
Basketball is a popular sport popular all over the world. Injuries caused by basketball are on the rise. Due to inattention to methods and methods in basketball, many participants have sports injuries, especially knee injuries, which are the most common.11. Šiupšinskas L, Garbenytė-Apolinskienė T, Salatkaitė S, Gudas R, Trumpickas V. Association of pre-season musculoskeletal screening and functional testing with sports injuries in elite female basketball players. Scientific reports. 2019;9(1):1-7. This has seriously affected the performance of high-level basketball players and the improvement of their athletic ability, thus shortening the athlete’s lifespan.
METHOD
Research object
The article focuses on 600 high-level basketball players from regular full-time colleges and universities as the research object.
Research methods
Questionnaire survey method
Design the questionnaire based on the research content. We selected dozens of Gaoping basketball students from each school as the survey subjects, and each handed out one questionnaire.22. Hadzovic M, Ilic P, Lilic A, Stankovic M. The effects of a knee joint injury prevention program on young female basketball players: a systematic review. Journal of Anthropology of Sport and Physical Education. 2020;4(1):51-6. A total of 600 questionnaires were distributed, and 563 were returned, with a recovery rate of 93.8%. There are 554 valid questionnaires, with an effective rate of 92.3%.
Mathematical Statistics
We input all data into the computer and use Microsoft Excel 2003 software for statistics, analysis, and processing.
Anatomy experiment method
We selected adult male knee joint specimens and made them into joint specimens that completely exposed the ligaments of various parts.33. Liu J. Prevention and Rehabilitation of Knee Joint Injury. Investigación Clínica. 2020;61(2):645-55. We saw horizontally at 20cm at the proximal and distal ends of the articular surface. The broken end is fixed and embedded with dental cement in the upright position. On the calf rotation shaft axis, screw 6 screws at the end of the femur with an interval of 2 cm. The angle of the nail and the axis of rotation are respectively 30°, 45°, 60°, 90°, 120°, and 150°. We fixed the specimens on the MTS material testing machine. The end of the femur is connected with a corresponding stabilization device. Apply flexion, extension, rotation moments, and flexion-extension simultaneous rotation moments on it, and measure the changes in knee joint flexion-extension and rotation angles.44. Wang Y, Jia Q, Deng T. The Effect of Ankle Joint Proprioception Training on Preventing Ankle Joint Injury of Athletes. Investigación Clínica. 2020;61(2):910-21. Finally, the article conducts a destructive tear test of the tibial collateral ligament, fibular collateral ligament, and anterior and posterior cruciate ligament. At the same time, the meniscus injury test and the biomechanical test were carried out.
Modeling and Simulation of Knee Joint Injury
Suppose X = ( X 1 , X 2 ,..., X p ) represents a P dimensional random vector. I represents a constant vector that affects the athlete’s elbow (knee) joint injury factor. Under the I i ' I i = 1 , i = 1,2 ...p constraint, we use the following formula to establish a linear transformation matrix that produces the athlete’s elbow (knee) joint injury factor
We use Y 1 to replace P original variables X 1 , X 1 ,..., X p that produce the athlete’s elbow (knee) joint injury factors, and require Y 1 to be able to express the information of the original variables.55. Li B, Xu X. Application of artificial intelligence in basketball sport. Journal of Education, Health and Sport. 2021;11(7):54-67. The characteristics of the relationship between basketball players’ overtraining and elbow (knee) joint injury factors can be expressed by the following formula
The larger the value of Var ( Y 1), the more information Y 1 contains the factors that affect the athlete’s elbow (knee) joint injury. We use I 1 to make Var ( Y 1) extremely large. The i principal component of X needs to satisfy the condition of Y i = I' i . I i represents the characteristics of the relationship between basketball players’ overtraining and the factors that affect athletes’ elbow (knee) joint injury. Σ represents X covariance matrix. We use the following formula to obtain a sample matrix of the elbow (knee) joint injuries caused by overtraining of basketball players
The correlation matrix of a sample of the elbow (knee) joint injury caused by overtraining of basketball players is expressed as follows
Establish a basketball player’s overtraining elbow (knee), joint injury model, based on the following formula:
RESULTS
Analysis of the structure and injury of the knee joint
We know that the knee joint is the most complicated part of the human body through physiological anatomy. It is formed by connecting the medial and lateral condyles of the femur, the patella, the medial and lateral condyles of the tibia, and the patella. Each joint surface is covered with a layer of joint soft muscle. At both ends of the knee joint, some femurs and tibias constitute levers. It receives greater stress than other joints during activities. Because the knee joint has the largest articular surface, superficial parts, and the strongest leverage, it has a heavy load, is unstable, and is easily injured. In basketball, the human body has more left and right sliding steps, making the knee joint’s medial collateral ligament easy to damage.66. Di Cesare CA, Montalvo A, Foss KDB, Thomas SM, Hewett TE, Jayanthi NA et al. Sport specialization and coordination differences in multisport adolescent female basketball, soccer, and volleyball athletes. Journal of athletic training. 2019;54(10):1105-14.
Analysis of the mechanism of basketball players’ knee joint injury
In the valid 554 questionnaires, 479 people answered that they had suffered sports injuries in basketball.77. Sola M, Gregov C. Injury epidemiology in the first Croatian basketball league. Kinesiology. 2021;53(1):162-71. Among them, 123 people suffered knee injuries, and the injury rate was 25.7%. ( Table 1 )
The technical action characteristics of basketball lead to different degrees of injury in various knee joint parts. Basketball players must have a low center of gravity when attacking or defending with the ball and are mostly in a squatting position, so the knee joints are highly strained and prone to injury. In high-level basketball players of colleges and universities, the medial collateral ligament injury and meniscus injury occurred more frequently in the knee joint injuries. The probability was 34.1% and 24.3%, respectively.88. Ramezani Ozineh M, Letafatkar A, Hadadnezhad M. Effect of external focus of attention and functional training on basketball knee stabilization muscle activity timing: A clinical trial study. Journal of Gorgan University of Medical Sciences. 2021;23(1):11-21. Patella strain and cruciate ligament injury accounted for 12.1% and 19.5%, respectively. Fracture injuries are relatively rare, accounting for only 2.4%.
The characteristics of basketball are the momentary alternation of offense and defense, sudden start, acceleration or stop, turning, jumping or squatting, and posture changes. Knee joint injury is one of the common injuries when playing basketball for a long time. The knee joint injury is most common when the offender’s body is in a non-contact state. Such as the change of direction in basketball, emergency stop, sidecut, etc. The survey showed multiple risk factors for a knee injury in basketball ( Table 2 ). One of the most basic physical characteristics in basketball is a low center of gravity. The knee joint is always in 130°~150° flexion when sliding or standing because this position is the best posture for the quadriceps to obtain the maximum torque. According to the anatomical experiment method, the electromyogram showed that the quadriceps muscle only participates in the knee extension when the knee joint is in this position, which increases the strength and effect of the extension. In addition, the collateral ligament and cruciate ligament of the knee joint are in a relaxed state at this position.99. Shovkiddin N, Eleonora Y, Surayo A, Nargiza K, Saodat N. Problems of Ensuring the Safety of Sports Activities and Reducing Injuries. Journal of Critical Reviews. 2020;7(11):428-32. This facilitates the direction change of the knee joint so that the knee joint is more flexible when changing direction. The contraction of the quadriceps muscle accomplishes the powerful take-off and landing. The strong contraction of the quadriceps makes the patella and femur collide. Repeated impacts can easily damage the cartilage of the patella and femur and cause patella-femoral arthropathy. This is often manifested as knee pain when athletes take off or land. In addition, long-term training can cause knee joint strain. As shown in Table 2 , the main causes of basketball injury are as follows:
DISCUSSION
Analysis of the causes of sports injuries
The level of sports training is not high
Basketball sports have relatively high requirements for participants’ physical fitness, including strength, speed, endurance, coordination, and agility. These qualities are necessary to complete the difficult technique in basketball technique. However, the physical fitness of some athletes is not very good. At the same time, they lack systematic training but want to try beautiful but difficult basketball skills. This greatly increases the chance of injury.
Insufficient preparation activities
Lack of warm-up or incorrect warm-up is the main cause of sports injuries. Most athletes don’t pay enough attention to warm-up activities. They think that warm-up activities consume physical strength, and they just do some simple leg presses, waist extensions, and sometimes no warm-up activities at all. This is the root cause of the damage. Therefore, the preparation activities must conform to the principle of science.
Improper arrangement of exercise volume
This is manifested in the amount of exercise that violates the principle of “gradual and orderly progress.” This makes local overburden, practice density, practice time, practice intensity, and other aspects unscientific and causes damage.
Psychological factors
The investigation found that athletes have the mentality to avoid training or teaching, worry about failure, and intend to punish others. Psychological factors such as emergency factors in life, major changes or inadaptability to the climate, low or high emotional state, and the level of social support can all cause damage to psychological fluctuations.
Site factors
The content includes dim lighting affecting eyesight, rough and uneven training venues, or damage caused by long-term training in cement venues.
Insufficient safety education
Coaches do not pay enough attention to the prevention of basketball injury and the safety education of students. Some students are aggressive and combative. To win the game, they often do not pay attention to sports ethics and do not abide by the game’s rules. This also caused some damage that shouldn’t have occurred.
Preventive measures for knee joint injuries in basketball
Strengthen moral and spiritual education for athletes. We require athletes to strictly abide by the game rules to prevent uncivilized and even brutal fouls on the court. Coaches strengthen safety education for athletes and enhance self-protection awareness. Be fully prepared before the start of the exercise. In this way, the flexibility and coordination of the joints can be improved. It is necessary to understand the structural characteristics of the knee joint and the confrontation law of basketball. Strictly require technical movements and sports precautions to save energy and effort during the exercise, without movement, and avoid injury. Efforts should be made to improve the conditions of the training and competition venues. Improve the teaching level of coaches and conduct scientific training. Teach students following their aptitude and arrange the amount of exercise training reasonably. Strengthen lower limb muscle strength training and improve joint sensitivity and stability. If the strength around the knee is strengthened, the injury can be avoided. Therefore, it is particularly important to increase the strength and stretching exercises of the lower extremity muscles in the teaching training. Master the methods of self-protection during exercise. Keep warm after exercise to prevent wind, cold, and dampness. Use hot bath, massage, and other means to accelerate the elimination of local fatigue. After the initial recovery from an injury, you must follow the principle of gradual and orderly progress when participating in physical exercise to avoid injury. Don’t play under overload and fatigue. Once a knee injury occurs, you must wait until you have fully recovered before exercising. In this way, as much as possible to avoid the recurrence of knee joint injuries.
CONCLUSION
The knee joint is one of the most vulnerable parts of basketball. The consequences of its injury can lead to the end of a sports career. This has a certain impact on the physical and mental health of athletes. Pay attention to the protection of knee joints in teaching and training. Pay attention to the inspection and treatment of knee joint injuries to improve the scientific nature of sports.
