Gonarthrosis, one of the most common types of arthritis, is characterized by the degeneration and deterioration of the cartilage tissue in the knee joint. Symptoms of gonarthrosis include pain, swelling, limited mobility, and eventually deformity of the joint. As the disease progresses, the complete wearing away of the cartilage tissue and the rubbing of the bones against each other can occur, leading to further reduction in pain and mobility.
The causes of gonarthrosis include aging, obesity, previous injuries to the knee, overuse, genetic predisposition, and certain diseases. Treatment varies depending on the severity of the disease and the overall health of the patient, and focuses on managing pain, increasing mobility, and improving quality of life. Treatment options may include medication, physical therapy, weight management, orthopedic supports, and in severe cases, surgery.
Causes of Gonarthrosis
Gonarthrosis has several underlying causes, and these causes are often interconnected:
Aging: As one ages, the cartilage tissue naturally wears down and weakens.
Obesity: Excess body weight puts extra pressure on the knee joints, which can accelerate the wearing down of the cartilage tissue.
Knee Injuries: Previous injuries to the knee like meniscus tears, fractures, or ligament damage can increase the risk of developing gonarthrosis.
Occupation or Sports Activities: Occupations or activities that constantly put the knees under high stress can accelerate cartilage wear and tear.
Genetic Predisposition: Individuals with a family history of osteoarthritis are at a higher risk of developing gonarthrosis.
Other Diseases: Inflammatory joint diseases like rheumatoid arthritis or metabolic disorders can contribute to the development of gonarthrosis.
Mechanical Factors: Structural abnormalities or misalignment that lead to abnormal loading of the knee joint can increase the risk of gonarthrosis by creating unequal stress on the cartilage.
Symptoms of Gonarthrosis
The symptoms of gonarthrosis can vary depending on the severity and progression of the disease:
- Pain
- Stiffness
- Limited mobility
- Swelling
- Crepitation (crackling or grinding sensation)
- Deformity
- Warmth in the joint
Diagnosis of Gonarthrosis
The diagnosis of gonarthrosis is usually made using a combination of clinical examination and medical imaging techniques:
Evaluation of Medical History: The doctor will inquire about the patient’s symptoms, the severity and duration of pain, previous injuries, and family history of osteoarthritis.
Physical Examination: The doctor will assess the location of the knee pain, range of motion, stiffness in the joint, swelling, and any deformity.
X-ray: X-rays can reveal changes in the bones of the knee, narrowing of the joint space, and any bone protrusions.
Magnetic Resonance Imaging (MRI): MRI can be used to evaluate the condition of soft tissues like cartilage, ligaments, and intra-articular structures in more detail.
Laboratory Tests: Laboratory tests such as blood tests and analysis of joint fluid can help differentiate gonarthrosis from other inflammatory joint diseases.
Treatment of Gonarthrosis
The treatment of gonarthrosis aims to alleviate symptoms, preserve joint function, and improve quality of life:
Lifestyle Changes and Weight Management: Excess weight can increase pain and symptoms by exerting extra pressure on the knee joints.
Physical Therapy and Exercise: Regular low-impact exercises and exercise programs specifically aimed at strengthening the knees can increase joint mobility and reduce pain.
Medication: Pain relievers and anti-inflammatory drugs are used to control pain and inflammation.
Orthopedic Supports: Supportive devices like knee braces and canes can help reduce pressure on the joint and support movement.
Arthroscopy: Damaged cartilage fragments can be removed by entering the joint through small incisions.
Osteotomy: Surgical procedure involving reshaping of bones and redistributing pressure on the joint.
Total Knee Replacement: This method can significantly reduce pain and improve joint function.
Management of Gonarthrosis
The management of gonarthrosis requires a comprehensive approach to alleviate symptoms, preserve joint function, and improve the patient’s quality of life:
Education and Self-Care: It is important to educate and train patients on the disease and management strategies.
Weight Management and Nutrition: Maintaining or achieving an ideal body weight reduces pressure on the knee joints.
Physical Activity and Exercise: Low-impact aerobic exercises, stretching, and strengthening exercises are important.
Medication: Oral and topical medications can be used for pain and inflammation.
Orthopedic Supports: Supportive devices like knee braces, shoe inserts, and walking aids can stabilize the joint and facilitate movement.
Surgical Options: Surgical methods like arthroscopy, osteotomy, or total knee replacement can be considered for severe cases.
Alternative and Complementary Therapies: Methods like acupuncture, massage, and thermal therapies can help alleviate symptoms for some patients.
Psychosocial Support: Psychological counseling or support groups can help cope with the psychological and social effects of the disease.
