Value evaluation of knee joint sports injury detection model-aided diagnosis based on machine learning

  • XinYang Vocational & Technical College, Xinyang, Henan, China

Athletes often suffer from knee joint injuries because they often use the knee joint to exert force during training. This paper aims to analyze and discuss the auxiliary diagnosis of the knee joint sports injury detection model based on machine learning. This paper expounds the treatment method of knee joint injury, and proposes a machine learning algorithm. On the basis of this research, the auxiliary diagnosis experiment of the knee joint sports injury detection model is analyzed. The experimental results show that after 3 months of machine learning-based rehabilitation training, there is a significant difference in the duration of the balance pad before and after the table tennis players practice. The duration of the athletes on the balance mat has increased, and the increase is relatively large. Among them, the average duration of female athletes on the balance mat increased from 75.5 seconds before training to 141.9 seconds after training, while the average duration of male athletes on the balance mat increased from 66.7 seconds before training to 136.8 seconds after training. Studies have shown that machine learning-based rehabilitation physical training can significantly improve athletes' endurance on balance mats and can improve knee function scores. In summary, machine learning-based rehabilitation physical training can effectively improve knee joint injuries.

1 Introduction

Table tennis is a kind of net competition in which players cannot have physical contact. However, in the competition, athletes must carry out high-intensity footwork. When the knee joint flexes for a long time, if the stability of the knee is not good, or if the muscle group close to the knee does not have enough strength, it may cause injury to the knee joint. In the training of table tennis players, coaches focus on special training and ignore other training, such as strength and body conditioning. They do not strengthen the weak ribs of the body, so the incidence of injuries to athletes is getting higher and higher. Second, due to the lack of supervision and protection of the team doctor, once an athlete is injured and the injury is not handled in time, it would affect the development of technology and tactics. In serious cases, this would lead to the athlete not being able to train normally. Sports injuries cause a great load on athletes’ bodies and seriously affect their daily lives and training. Therefore, the development of rehabilitation physical training can prevent and treat knee injuries and improve the function of knee joints, reduce knee joint injuries, and enable athletes to get rid of injuries. The purpose of this paper was to analyze and discuss the auxiliary diagnosis of the knee joint sports injury detection model based on machine learning to make certain contributions to knee joint injury repair.

According to the research progress, different researchers have also made corresponding cooperative research on knee joint sports injuries. Most knee injuries are caused by the increase in vertical pressure, which is generally due to accidental falls, collisions, or high jumps during skiing. Trobec R introduced a new mechanism of non-contact knee joint injury that could occur during gliding [1]. Snooker B found through research that the probability of knee osteoarthritis would be increased by six times after knee joint injury. The most dangerous injuries are cruciate ligament, meniscus tear, and intra-articular fractures [2]. Welsch GH carried out semiquantitative occupational knee MRI examinations in the “medical” stage and studied the relationship between clinical data and knee injury absenteeism rate [3]. Goreta R conducted a new questionnaire survey on knee pain and injuries among 39 top Croatian League A players, and the results showed that the test instrument had good measurement performance [4]. However, these scholars lack some technical demonstration in the research of knee joint sports injuries. It is found that machine learning has a better discovery in the research of knee joint sports injuries. In this regard, the relevant literature on machine learning was consulted.

Some scholars also carried out some research on machine learning. Hinterwimmer F aimed to study whether machine learning models used in artificial knee surgery are feasible and to determine the premises for the effective application of this new technology [5]. The purpose of Smna B is to study a machine learning method based on big data before surgery, which can be used to predict the hospitalization time and hospitalization cost of patients with initial knee replacement [6]. Verstratete M A evaluated the application of a monitored machine learning model to evaluate the orthopedics of total knee surgery based on patients’ special operations [7]. However, these scholars did not analyze and discuss the auxiliary diagnosis of a knee joint sports injury detection model based on machine learning, they just unilaterally discussed its significance.

This paper drew the following conclusions by analyzing the experimental results of the auxiliary diagnosis of the knee joint sports injury detection model. After the rehabilitation physical training based on machine learning, the endurance of athletes on the balance pad could be effectively extended. At the same time, it improved the score of the knee joint function rating scale. In a word, rehabilitation physical training based on machine learning plays a certain role in preventing and treating knee trauma.

The innovations of this paper are as follows: 1) the treatment of knee joint injuries is analyzed, and a method of building a knee joint sports injury detection model based on machine learning is proposed; 2) by taking table tennis players as an example, this paper makes an experimental study on the repair of their knee joint injuries.

2 Investigation method of knee joint sports injury based on machine learning

2.1 Treatment of knee joint injury

The knee joint is the largest and most complex joint composed of the tibiofemoral joint and the patellofemoral joint. The femoral condyle and the nearly flat proximal articular surface of the tibia form a joint, so the stability is poor. This mainly depends on the joint capsule, ligament, meniscus, and surrounding strong muscle groups. The anatomical structure of the knee joint is complex, and it bears the weight and greater stress of the body. Its stability is poor, so the knee joint is easy to be injured [8]. The knee joint injury is shown in Figure 1. After a knee joint injury, surgical treatment is ruled out, and conservative treatment is often performed with physical therapy. Physiotherapy uses physical factors such as force, light, electricity, sound, water, and temperature to treat diseases. Physical therapy commonly used after knee joint injury includes physical factor therapy and exercise therapy.

(1) Physical factor therapy

FIGURE 1

FIGURE 1. Knee joint injury.

Physical factor therapy can prevent and treat diseases through various physical factors, including natural physical factors and artificial physical factors. Natural physical factors include seawater, air, sunlight, and mineral springs. Artificial physical factors include electricity, sound, magnetism, light, and heat [9]. Physical factor therapy has the functions of analgesia, anti-inflammatory, improving blood circulation of tissues and organs, relieving muscle spasms, and promoting tissue repair and regeneration. Cold therapy, ultrashort wave therapy, and ultrasound are the commonly used physical factor therapy after knee joint injury. Cold therapy is a kind of therapy that uses ice water or ice cubes that are lower than the body temperature to stimulate the skin or mucous membrane. It has the effect of preventing further tissue swelling and relieving pain. Therefore, cold therapy can be used to treat acute inflammation after knee joint injury [10]. Ultrashort wave therapy belongs to high-frequency electrotherapy, which can produce physiological effects on the human body through non-thermal and thermal effects. It can promote the expansion of capillaries and enhance the permeability of the blood vessel wall [11]. It can also improve blood circulation, inhibit the conduction of sensory nerve fibers, and promote tissue metabolism. Therefore, it can diminish inflammation, relieve pain, and promote the regeneration of connective and granulation tissues.

(2) Exercise therapy

Exercise therapy is an essential rehabilitation method, and physical and mechanical factors are used to carry out exercise therapy. It is a very effective rehabilitation method to correct limb dysfunction and abnormal movement posture through multiple movements [12]. The rehabilitation methods for knee joint injuries include a range of joint motion training, muscle strength training, balance and proprioception training, and functional training.

2.2 Machine learning algorithm

Machine learning is the use of computer algorithms, statistical models, and computer systems to gradually improve the ability to complete specific tasks. Nowadays, with the wide application of machine learning algorithms in the medical field, many machine learning algorithms that can solve specific medical problems have also been significantly developed [13]. Figure 2 shows the application of machine learning in medicine. In the past 10 years, the use of machine learning algorithms to predict diseases has been rapidly developed [14]. Ranging from macrophysiology and behavior and experimental basic research and imaging research to increasingly “omics” data, machine learning algorithms are applied.

FIGURE 2

FIGURE 2. Application of machine learning in medicine.

As a machine learning algorithm based on statistical learning, support vector machine (SVM) has a good application prospect in the fields of small sample, non-linear, and high-dimensional pattern recognition [15]. Therefore, by considering the actual medical data collected and the number of data samples, features, and other factors of the public disease dataset used, this study uses SVM to build a knee joint sports injury detection model. SVM is widely used in various pattern recognition problems, such as portrait recognition, text classification, handwritten character recognition, and bioinformatics.

The basic idea of a support vector machine is to segment the dataset on the optimized hyperplane [16]. The purpose of this paper is to use SVM to summarize the data of knee joint sports injury and to determine its diagnosis methods. Given the sports training data F=c1,u1,c2,u2,,cz,uz,uo=1,+1, under the condition that the sports injury training data are linearly decomposable, the hyperplane of the sports injury training data is defined as the following linear equation:

eYc+n=0.(1)

Here, e is the normal vector of the hyperplane and n is the distance from the hyperplane to the origin. The distance between c and the hyperplane can be expressed using the following formula:

t=eYc+ne(2)

If the data in F can be correctly divided by the hyperplane according to the classification requirements, we obtain co,uoF. When uo=1, eYco+n>1. When uo=1, eYco+n<1. The formula is given as follows:

eYco+n+1,uo=+1eYco+n1,uo=1(3)

The distance of the two nearest points to the hyperplane is as follows:

t=2e(4)

At this time, the so-called optimal hyperplane is also the hyperplane that maximizes t. The problem for solving the optimal hyperplane can be expressed as follows:

max,n2es.t.uoeYco+n1(5)

The formula is given as

mine,n12e2s.t.uoeYco+n1(6)

The model corresponding to the optimal hyperplane obtained by solving Formula 6 can be expressed as follows:

gc=eYc+n(7)

When the sports injury training data are non-linear and separable, there may not be any hyperplane in the original feature space that can accurately divide the data categories. At this time, SVM makes the sample data separable by mapping the sports injury original data to the high-dimensional space. The corresponding model is shown as follows:

gc=eYc+n(8)

Here, c represents the feature vector after mapping the original data c, and Formula 6 can be written as follows:

mine,n12e2s.t.uoeYco+n1(9)

Its dual problem is as follows:

maxβo=1zβo12o=1zk=1zβoβkuoukcoYcks.t.o=1zβouo=0(10)

When the characteristic dimension is high, it is difficult to calculate the inner product coYck of co and ck. Therefore, SVM uses the kernel function instead of the internal multiplication operation in the high-dimensional feature space, so Formula 10 can be rewritten as follows:

maxβo=1zβo12o=1zk=1zβoβkuouklco,cks.t.o=1zβouo=0(11)

After being solved, the formula is simplified as follows:

gc=o=1zβouolc,co+n(12)

In addition, in practical problems, it is difficult to determine an appropriate kernel function so that each data sample in the training set can be accurately divided. Therefore, SVM also introduces the concept of the soft interval, which allows it to make mistakes on some samples, that is, some samples cannot meet the constraints of Formula 13.

uoeYco+n1(13)

However, when searching for the optimal hyperplane, the number of samples that do not meet the constraints of Formula 13 is required to be as small as possible, and the relaxation variable τo is introduced to indicate the extent to which each sample does not meet the constraints. The optimization problem of the model can be expressed as follows:

mine,n,τo12e2+Vo=1zτos.t.uoeYco+n1τo(14)

Here, V is the penalty factor. After the concept of kernel function being introduced, the support vector model that is same as shown in Formula 12 can be obtained.

The kernel function and penalty factor V have a great impact on the final performance of SVM [17]. Only proper kernel functions and reasonable parameter settings can make the sample data linearly separable in the feature space. For the penalty factor V, when the value of V is too large, the relaxation variable would be very small and the allowable error would also be smaller. Therefore, the classifier would try to classify the samples correctly to obtain a small spacing hyperplane. This may lead to the poor classification performance of the model for test data, while the classification performance on the training set is very good. On the contrary, if the value of V is too small, the allowable error of the model would be large. Even if the training set is linearly separable, there may be wrongly classified samples, resulting in the phenomenon of under-fitting. With the development of the social medical level, the scale of medical databases is increasing rapidly. Unfortunately, most of the data have not been analyzed to discover valuable hidden laws. Now, people can integrate these data and use machine learning algorithms to discover hidden relationships. The models developed through these technologies would help doctors make correct diagnostic decisions.

3 Evaluation of the auxiliary diagnosis experiment results of the knee joint sports injury detection model

3.1 Investigation objects and methods

The research object is the knee joint injuries of table tennis players in a normal university.

Subjects: 18–24 years old; table tennis level II (or higher); athletes who meet the Functional Movement Screen (FMS) and the knee joint rating scale would get not more than 8 points (12 points in total) in the FMS exam and 90 points (100 points in total) in the knee joint exam.

The rehabilitation physical training program based on machine learning is formulated. This training is conducted in two phases, that is, it is conducted after the table tennis training. During training, the intensity and load of athletes will vary according to their physique and gender. After receiving the body recovery training based on machine learning, athletes must actively cooperate and stop other aspects of training.

3.2 Changes in athletes’ body shape indicators

Figure 5 shows the scores of athletes’ FMS tests. Figure 5A shows the FMS test scores of female athletes, and Figure 5B shows the FMS test scores of male athletes. After 3 months of recovery, the FMS scores of female athletes before and after training were tested with the independent sample T. The results showed that there were significant differences in the performance of female athletes in squats, hurdles, lunge squats, straight knee lifts, and other events. Among them, the average score of female athletes before training was 1.7 points for deep squats, 1.8 points for hurdles, 1.9 points for bow squats, and 2.1 points for straight knee lifting; after training, the average score of female athletes was 2.3 points for squats, 2.4 points for hurdles, 2.4 points for lunge squats, and 2.6 points for straight knee lifting. Before training, the knee joint stability of female athletes was poor, and the female athletes showed obvious shaking in the hurdle test, with an average score of 1.8 points. However, after training, the average score of female athletes in hurdles rose to 2.4. Through the independent sample T, male athletes showed significant differences in the scores of squats before and after training, and there were significant differences in the scores of hurdles, lunge squat, straight knee, and leg lifting.

3.5 Repair of athletes’ knee joint function

\After 3 months of rehabilitation and physical training, the knee joint functional assessment scale showed significant differences before and after training. Athletes started table tennis training at an early age and lack knowledge of sports injury prevention, and coaches rarely conduct rehabilitation physical training. Therefore, long-term special training has caused chronic injuries to athletes’ knees and other parts. In addition, table tennis players have no warm-up activities before special training. After training, relaxation without traction is likely to lead to muscle fatigue. Some athletes said that when the exercise intensity is high, the knee joint would have slight discomfort. Therefore, in rehabilitation training, it is necessary to constantly remind and guide athletes to join in dynamic stretching, muscle activation, and other warm-up activities before special training; after the training, it is necessary to carry out fascia relaxation, static traction, and other relaxation activities. After rehabilitation and physical training, the strength of the muscles around the knee joint of the athletes would be improved through strength training, such as resistance knee extension training and resistance knee flexion training of the legs. This can improve the stability of the athletes’ knee joints and reduce the injuries of athletes in high-intensity sports. After 3 months of rehabilitation training, the scores of the table tennis players on the knee function assessment scale have improved. The average score of female athletes’ knee joints increased from 89.0 before training to 92.8 after training; the average score of male sports knee joints increased from 88.6 before training to 93 after training. This shows that the rehabilitation physical training based on machine learning improves the score of the knee joint function scoring scale.

4 Conclusion

Machine learning can improve people’s ability to solve problems and draw reasonable inferences from a large number of problems, including assisting in disease diagnosis and developing solutions to global climate change. The purpose of this paper was to discuss the value of the auxiliary diagnosis of knee joint sports injury detection models based on machine learning. Rehabilitation training based on machine learning plays a key role in the prevention and treatment of knee joint injuries. The use of fascia relaxation, balance pads, and other methods could improve the movement ability and stability of the knee joint and reduce damage to the knee joint. At the same time, the strength of the muscles around the knee joint such as the quadriceps femoris could be strengthened through rehabilitation training such as resistance training of flexors and extensors and static squatting training by machine learning to prevent knee injuries. Therefore, machine learning is an effective method for rehabilitation training. However, due to the particularity of the athletes’ physiques, it was necessary to formulate corresponding rehabilitation training plans for different athletes during the recovery process. However, due to the limitation of time and technology, the specific causes of knee joint injuries have not been analyzed and discussed in detail in this paper, which would be further studied in the future.
