Knee joint contracture: manifestations, factors, and treatment methods

Understanding knee joint contracture

Knee joint contracture, also known as muscle and ligament shortening, is a condition in which the joint becomes restricted in its normal mobility due to shortening and thickening of connective tissues. This can occur for various reasons, including prolonged immobility of the joint, trauma, or inflammation. Patients with knee joint contracture may experience stiffness, pain, and difficulty in performing daily movements, which significantly reduces their quality of life. Treatment usually includes physical therapy, stretching of muscles and ligaments, and sometimes is complemented by surgical intervention to eliminate tissue shortening and restore joint mobility.

Etiology of knee joint contracture

Knee joint contracture is a pathological condition characterized by limited movements in the joint due to the shortening of muscles, tendons, or the capsule. The main causes of this condition may include congenital anomalies, injuries, chronic inflammatory processes, as well as a number of neurological diseases. Factors that contribute to the development of contractures include a sedentary lifestyle, prolonged absence of physical activity, and certain physiological changes such as foot drop and tissue fibrosis.

  • Injuries: Damage to the ligaments, tendons, or bones of the knee can lead to the development of contracture.
  • Surgical interventions: After surgeries on the knee joint, inflammation may occur, leading to contracture.
  • Joint diseases: Arthritis and other inflammatory diseases can provoke the development of knee joint contracture.
  • Lack of physical activity: The absence of regular exercise and stretching of the muscles can lead to shortening and contracture.
  • Congenital anomalies: Genetic features may contribute to the occurrence of knee joint contracture at an early age.

Manifestations of knee joint contracture

Clinical manifestations of knee joint contracture include restricted joint mobility, which may manifest as difficulty in straightening or bending the knee, as well as pain during movement. Patients may also experience a sensation of stiffness and tension in the knee area, which affects their ability to perform daily activities.

Other typical manifestations of knee joint contracture include reduced muscle mass in the thigh and calf area, as well as changes in gait due to limited movement in the knee joint. A notable sign of contracture may also be the appearance of joint deformation due to the loss of its natural anatomical shape.

  • Joint mobility restriction: Patients with knee joint contracture may experience difficulties in bending or straightening the knee, which significantly limits their mobility.
  • Pain and discomfort: The sensation of pain during movement or at rest is a common symptom of knee joint contracture and can be particularly intense during certain movements.
  • Feeling of stiffness and tension: Patients may describe a sense of unusual “tension” or stiffness around the knee, reflecting mobility restrictions and the inability to fully straighten or bend the leg.
  • Muscle mass reduction: Knee joint contracture can lead to muscle atrophy in the thigh and calf due to limited use of the joint and lack of physical activity.
  • Joint deformation: Prolonged contracture may cause a change in the shape of the knee joint, affecting its functionality and appearance. The knee may take on an abnormal shape due to shortening of tissues and muscles.

Expert opinion on the treatment of knee joint contracture

Expert opinion on the treatment of knee joint contracture is based on a comprehensive approach to the problem, taking into account the individual characteristics of the patient and the degree of disease progression. Experts emphasize the importance of timely and accurate diagnosis of knee joint contracture to determine the optimal treatment plan. Depending on the degree of joint mobility limitation and the presence of concomitant factors, specialists may recommend conservative treatment methods such as physiotherapy, medication therapy, and exercises to improve flexibility and muscle strength, or surgical intervention in cases where conservative methods do not yield the desired effect or the condition of the joint requires surgical correction.

Methods for diagnosing knee joint contracture

Various methods are used for the diagnosis of knee joint contracture, including clinical examination, joint examination, X-rays, as well as magnetic resonance imaging (MRI) and arthroscopy. The clinical examination by the doctor allows for the assessment of joint mobility, the presence of pain and deformities, as well as the need for additional investigations.

X-rays help to identify changes in the structure of the joint, such as bone spurs or narrowing of the joint space. MRI, on the other hand, provides a more comprehensive view of the condition of the soft tissues of the joint, allowing for the detection of changes in muscles, tendons, and the joint capsule. Arthroscopy can be used for detailed and direct examination of the internal structures of the knee joint and simultaneously performing therapeutic manipulations.

  • Clinical examination: Includes the assessment of knee joint mobility, the presence of pain sensations, and the nature of deformities.
  • X-ray: Allows visualization of changes in the structure of the joint, such as bone deformities and narrowing of the joint space.
  • Magnetic resonance imaging (MRI): Provides detailed images of the soft tissues of the joint, allowing for the detection of changes in muscles, tendons, and the capsule.
  • Diagnostic arthroscopy: Used for direct examination of the internal structures of the knee joint, and may also include performing therapeutic procedures.
  • Ultrasound examination: Allows assessment of the condition of the soft tissues of the joint and structures such as tendons and ligaments, without the use of ionizing radiation.

Approaches to the treatment of knee joint contracture

Treatment of knee joint contracture may include conservative methods such as physiotherapy, exercises to strengthen the muscles, massage, and joint stimulation aimed at improving mobility and reducing pain. In some cases, surgical intervention may be required, especially in the case of ongoing shortening of the tendons or joint capsule. Surgical methods may include cutting or shortening of tendons, arthrotomy to restore full joint mobility, or arthrodesis to fix the joint in an optimal position.

When treating knee joint contracture, it is important to individualize the approach based on the severity of the condition, the patient’s age, the presence of comorbidities, and other factors. Comprehensive treatment, including physical therapy, medication, and rehabilitation, can help restore knee joint function and improve patients’ quality of life.

  • Physiotherapy: conducting special exercises and procedures to restore mobility and strengthen the muscles around the knee joint.
  • Medication treatment: using medications to relieve pain, reduce inflammation, and improve blood flow in the knee area.
  • Surgical intervention: in some cases, surgical treatment may be required to restore the mobility and function of the knee joint.
  • Massage and manual therapy: special massage techniques and manual therapy to improve blood circulation, relieve muscle tension, and restore joint mobility.
  • Use of orthoses and assistive devices: wearing orthoses or other special devices to hold the joint in an optimal position and facilitate movement.

Preventive measures against knee joint contracture

Preventive measures are aimed at preventing the development of knee joint contracture and include regular physical exercises to strengthen the muscles around the joint, maintaining a healthy lifestyle with adequate physical activity, as well as proper nutrition considering the need to maintain a healthy weight. An important aspect of prevention is avoiding prolonged periods of immobility and proper positioning of the joint during sitting or sleeping to prevent stiffness and shortening of the muscles.

In addition, regular check-ups with doctors, timely treatment of joint injuries and inflammatory processes, as well as following the recommendations of specialists in physical therapy and rehabilitation after injuries or surgeries can help reduce the risk of developing knee joint contracture.

  • Regular physical exercises: moderate exercises aimed at strengthening muscles and maintaining knee joint flexibility can help prevent muscle shortening and the development of contracture.
  • Healthy lifestyle: maintaining a healthy lifestyle with moderate physical activity and a balanced diet contributes to overall joint health.
  • Correct body positioning: proper positioning of the knee joint when sitting or sleeping will help prevent stiffness and muscle shortening.
  • Regular medical check-ups: systematic consultations with doctors will help timely identify potential issues with the knee joint and take necessary measures.
  • Avoiding prolonged immobility: regularly changing positions and active movement contribute to maintaining the health and mobility of the knee joint.

Unusual aspects of knee joint contracture

Knee joint contracture is a condition that can lead to serious mobility limitations and significantly hinder the patient’s daily activities. Additional aspects of knee joint contracture may be related to psychological factors, such as feelings of helplessness and depression due to movement restrictions and loss of independence in daily life.

One interesting fact about knee joint contracture is the possibility of this condition developing in various age groups, including both children and adults. In children, knee joint contracture may result from congenital anomalies or diseases, while in adults, it is more often associated with injuries or age-related changes. This fact underscores the importance of early diagnosis and timely treatment of knee joint contracture across different age categories.
