Rehabilitation of sports working capacity in athletes after a knee joint injury

The main goal of the study was to assess the range of movements and determine the effectiveness of the physical rehabilitation of athletes (wrestling Zorkhana and Pahlevani) after a knee joint injury. The proposed version of the program, developed for the physical rehabilitation of athletes with knee injuries, turned out to be very effective in helping them return to sports and continue professional activity. This result is due to the use of an integrated approach to recovery during the rehabilitation process with phased, permanent, and individual treatment. Compliance with these principles made it possible to eliminate the morphological and functional consequences of knee joint injury as completely as possible.

To explore the rehabilitation effect of acupuncture on motorcycle athletes’ knee injuries. Firstly, 60 city association motorcycle athletes with knee joint injuries were selected, and the control group and the experimental group were tested and compared by random grouping. The control group received a series of planned rehabilitation training followed by traditional Chinese massage to relax. The experimental group used acupuncture therapy plan for rehabilitation after rehabilitation training. After the control group and the experimental group have completed the test, the data is measured to compare the knee joint function score (Lyholm) grade differences and pain scores at several different time nodes and observe and analyze them. The Lysholm score and pain score of the control group at different time nodes are both Lower than the experimental group, the difference was statistically significant (P<0.05). Data experiments prove that acupuncture therapy is more effective for knee joint injury rehabilitation, and is better than general traditional Chinese massage therapy. For motorcycle athletes’ knee joint injury rehabilitation, acupuncture therapy combined with rehabilitation training can significantly reduce athlete’s knee joint pain, reduce the number of athletes’ injuries, speed up knee joint injury recovery, increase joint mobility, and improve rehabilitation efficacy.

Introduction and Aim: Physical activity is one of the main risk factors for knee joint injuries, and the risk depends on the specific sport. Each part of the knee joint can be at different risk of injury. Diagnosis, treatment and rehabilitation are key to returning to full mobility, but vary depending on the type of injury. The purpose of this article is to present risk factors, diagnosis, treatment and prognosis in the most common knee joint injuries. Review Methods: 35 studies from PubMed and Google Scholar were analyzed to examine the relationship between physical activity and knee joint injuries. Joint anatomy, diagnosis, treatment and rehabilitation in the context of amateur and professional sports were considered. State of Knowledge: Knee joint injuries often result from sudden movements. ACL rupture is the most common injury, often non-contact. Diagnosis is based on history and imaging studies, such as magnetic resonance imaging (MRI) to evaluate soft structures and X-rays for bone injuries. Treatment depends on the type of injury: in mild cases rehabilitation is sufficient, in more serious cases surgery. Summary: Physical activity is a major risk factor for knee injuries, and the most common injury is an ACL injury. The risk depends on the mechanism of injury, age, weight and previous injuries. It is crucial to take a history, do a physical examination and perform imaging to make a diagnosis. Proper diagnosis allows for the selection of the appropriate treatment and rehabilitation method, which affects the patient's prognosis and return to full physical activity.

Although proprioceptive and neuromuscular exercises are considered to be part and parcel of rehabilitation programs after sport injuries, there is an uncertainty regarding the effectiveness of corresponding training interventions. The objective of this review was to evaluate the effectiveness of proprioceptive and neuromuscular training (PT/NT) for the treatment of ankle, knee, and shoulder joint injuries. Two independent reviewers performed a literature search in various databases and reference lists of articles. Data of included trials were then extracted, and methodological quality was assessed by using predetermined forms. Fifteen trials met the inclusion criteria. PT/NT was effective at increasing functionality as well as at decreasing the incidence of recurrent injuries and "giving way" episodes after ankle sprains and in conservative treatment of anterior cruciate ligament injuries. However, conflicting results or no efficacy of training were reported for static postural control, joint position sense, neuromuscular control, joint laxity, and lower extremity strength. No study that examined PT/NT after shoulder injuries was found. From this review, it can be concluded that proprioceptive and neuromuscular interventions after ankle and knee joint injuries can be effective for the prevention of recurrent injuries and the improvement of joint functionality.

One of the most frequent issues humans have had to deal with from the beginning of time is a knee injury. Knee injuries caused by a variety of diseases, from acute to degenerative, can affect the articular cartilage. The trauma, infection, or inflammation caused this injury. In these circumstances, a full clinical examination is not possible since the patients are in too much pain to cooperate. Then non-invasive multiplanar imaging and MRI come into play. The objective of the current study was to assess knee joint injuries using MRI and correlate those findings with arthroscopy. A total number of 225 participants were involved in this study, among them, 175 had issues with a knee injury. The patients referred with a history of knee injury were imaged with a 1.5 Tesla MRI machine. Most patients were between the ages of 35-40 years. The most frequent injuries found in the study were bone contusions, joint effusions, anterior cruciate ligament tears, and tears of the posterior horn of the medial meniscus. The accuracy percentage of ACL, PCL, LCL and MCL were 93, 100, 94.02 and 91.34%, respectively. Due to its great soft tissue contrast resolution and multiplanar imaging capabilities, magnetic resonance imaging (MRI) is a superior non-invasive investigative method for knee injuries. This allows for the most thorough evaluation of a variety of soft tissue knee joint problems. Keywords: Knee joint injury; Magnetic resonance imaging; Arthroscopy;

Knee joint injuries as a reconstructive factors in car-to-pedestrian accidents

It is important to predict the potential harm to the knee joint in order to prevent football players from inflicting numerous injuries to the knee during activity. Numerous professionals have been drawn to this subject, and many viable prediction systems have been developed. Prediction of potential knee joint injury is critical to effectively avoid knee joint injury during exercise. The current prediction algorithms are mainly implemented through expert interviews, medical reports, and historical documents. The algorithms have problems with low prediction accuracy or precision values. There is a need to understand more knee injury factors and improve the prediction accuracy; hence, the intelligent prediction algorithm for potential injury of knee joints of football players is proposed in this paper. Firstly, the characteristics of the knee joint injury and the injury factors of the football players are gathered and analyzed. Then, the damage is predicted by the similarity measurement. The experimental results show that the proposed algorithm has higher prediction accuracy and shorter time. According to the findings of a survey that collected healthcare data, several key factors contribute to football knee injuries. To a degree, this algorithm can predict the likelihood of a football player's knee injury.

This study was aimed at exploring the application value of augmented reality (AR) in postoperative rehabilitation training for patients with knee joint injury. 40 patients who underwent knee joint injury surgery were selected as the research objects, and the patients were randomly divided into two groups: an experimental group (20 cases) and a control group (20 cases). Patients in the experimental group were treated with AR-based rehabilitation methods, while those in the control group were treated with traditional rehabilitation methods. Afterwards, the two groups of patients were compared with various indicators such as pain value, swelling, structural and functional recovery, time to complete weight bearing, time to return to work, and X-ray examination results. The main evaluation tools used were Hospital for Special Surgery (HSS) score and Visual Analogue Scale (VAS) score. The results showed that after six weeks, the HSS score of the control group was 82.88 ± 3.07, and the HSS score of the experimental group was 85.46 ± 3.21. The difference between the two groups was statistically significant (P < 0.05). After three months, the HSS score of the control group was 89.96 ± 3.76, and that of the experimental group was 93.21 ± 4.33. The difference between the two groups was statistically significant (P < 0.05). There was a significant difference in pain scores between the two groups at 7 days (3.81 ± 0.48 vs. 5.06 ± 0.66) and 14 days (2.03 ± 0.45 vs. 3.61 ± 0.63) after surgery, with statistical significances (P < 0.05). There were statistically significant differences between the two groups in terms of time to complete weight bearing (7 ± 0.87 weeks vs. 8.82 ± 0.88 weeks) and time to return to work (8.69 ± 0.94 vs. 9.93 ± 0.88 weeks) (P < 0.05). One month after surgery, the X-ray examination results of both groups showed recovery. The AR-based rehabilitation training system showed a good application effect and prospect in the postoperative structural and functional recovery of patients with knee joint injury.

Background: With the recent development in imaging techniques such as higher resolution, lesser artifacts, shorter imaging timing and higher accuracy MRI had changed the traditional algorithm for workup of knee joint pathology particularly in twisting injuries of knee where there is a chance of internal derangement is suspected. Aim: To assess the efficacy of MRI in detecting ligament, meniscal and bony injuries of knee joint among the patients with knee joint injuries. Methodology: A cross-sectional study was conducted for a period of one year among patients reported with knee joint injuries in the age group between 15 and 35 years. . A total of 60 patients were taken as our study sample. All patients initially screened with X-ray followed by MRI using 1.5 tesla Siemens 16 machine. Meniscal and ligament tear were evaluated and graded based on the radiological grading and any other pathological conditions appeared in the bones or soft tissues were also noted. Results: Identifying the anterior and posterior cruciate ligament tear was more with MRI technique compared to X-ray and the difference was also found to be statistically significant (p.05). Similarly joint effusion, bone marrow edema and certain bony lesions are picked up by MRI rather than X-ray. Conclusion: Though X-rays are considered as the investigation of choice by orthopedicians for diagnosing bony pathologies, MRI is highly efficacious in detecting the internal derangements that occurs in knee injuries other than the bony lesions.

There are several common findings and contradictions noted in the research related to thigh muscle reflex inhibition and sequelae that occur with knee joint injury. Reflex inhibition may be measured directly by electromyography, or the sequelae of reflex inhibition may be measured, as commonly occurs in the clinic setting. Electromyography is useful in determining the causes of reflex inhibition. The most frequently cited causes of thigh muscle reflex inhibition in knee injury are pain, joint effusion and knee immobilisation. The other measurement methods described vary from thigh circumference measurement to muscle biopsy. These methods are useful in determining the magnitude and duration of the deleterious sequelae that affect the thigh muscles after reflex inhibition. Finally, there is selectivity of reflex inhibition after knee joint injury: the quadriceps versus the hamstrings, the different components of the quadriceps muscle group, and the different types of muscle fibres. In light of these findings, several suggestions have been offered for prevention of reflex inhibition and for techniques that can be applied to rehabilitate the most affected muscle group: the quadriceps femoris. Techniques used to prevent or limit the amount of reflex inhibition include cryotherapy, transcutaneous electrical nerve stimulation, iontophoresis, phonophoresis, joint mobilisation, rest and proper positioning of the knee in rest and exercise. Electromyostimulation, electromyographic biofeedback and traditional exercise training are 3 methods used to rehabilitate the quadriceps.

Primary care physicians only moderately confident in deciding which patients to refer for total joint arthroplasty of the hip and knee

Background: Osteoarthritis is a substantial cause of disability. Joint replacement prevalence relates to the burden of severe osteoarthritis, and identifying risk factors for end-stage disease may indicate intervention opportunities. American football has high youth and elite participation, and determining risk factors for severe osteoarthritis may support future morbidity prevention. Purpose: To (1) determine the prevalence of hip and knee replacement in retired National Football League (NFL) athletes, (2) examine risk factors for replacement, and (3) identify the association between knee injuries and knee replacement. Study Design: Case-control study; Level of evidence, 3. Methods: Retired NFL athletes who participated in a general health survey were included. This historical cohort included those playing between 1929 and 2001. The association between self-reported playing or injury history, and replacement after retirement, was assessed with prevalence ratios (PRs). Models were adjusted for potential confounders of age and weight. Results: Data for 2432 retired male NFL players (69.3% response rate) who had participated in football for a mean 15.2 years were included, in which 277 players reported replacement after retirement (11.4%). More participants reported knee replacement (7.7%) than hip replacement (4.6%). The majority of participants reported previous severe knee injury (53%), and the most prevalent was meniscal tear (32.2%). In multivariable models, age (10-year increase, PR, 2.23; 95% CI, 1.99-2.51), current weight (PR, 1.10; 95% CI, 1.06-1.14), and reporting 1 (PR, 1.78; 95% CI, 1.14-2.77), 2 (PR, 1.91; 95% CI, 1.16-3.15), or ≥3 knee injuries (PR, 3.44; 95% CI, 2.33-5.09) were associated with knee replacement. Age (10-year increase, PR, 1.86; 95% CI, 1.59-2.18), linemen (PR, 1.62; 95% CI, 1.03-2.55), and reporting 1 (PR, 1.72; 95% CI, 1.05-2.80), 2 (PR, 2.77 95% CI, 1.58-4.84), or ≥3 (PR, 2.44; 95% CI, 1.52-3.91) hip injuries were associated with hip replacement. Each reported knee injury type was cross-sectionally associated with replacement after retirement (P < .05). Conclusion: Knee replacement was more prevalent than hip replacement. Risk factors differed between the hip and the knee, with age and severe joint injury associated with hip and knee replacement, weight with knee replacement, and playing position associated with hip replacement. Joint injury and weight management may be prevention opportunities to reduce morbidity and end-stage osteoarthritis in this population.
