Description détaillée
Osteoarthritis is a degenerative disease characterized by progressive joint damage.The knee is one of the joints most affected by this pathology, and it is estimated that 10% of men and 13% of women older than 60 years present it.It is characterized by pain, functional limitation, and reduction of quality of life.
Knee osteoarthritis (KOA) is a multi-etiological, chronic disabling disease that affects the entire knee joint, which is the most common site of involvement in OA. KOA is classified as primary or secondary depending on etiology. The pathogenesis of primary KOA is complex and involves numerous factors, such as mechanical stress, inflammation, metabolism, immunity and genetics, with age, genetics, body weight, sex and race being risk factors.
Diagnosis of knee osteoarthritis can be confirmed based on clinical and/or radiological features. The potential of a progressive disease can be prevented or decreased by earlier recognition and correction of associated factors.Obesity and alignment especially varus malalignment are recognized factors of a progressive disease. Both non pharmalogical as well as pharmacological modalities of treatment are useful in managing the symptoms of knee osteoarthritis. Surgery should be considered only in patients who do not respond to medical therapy.
Varus knee osteoarthritis is one of the most common knee diseases in clinical practice. Knee pain and limited range of motion seriously affect the patient's quality of life. However, there is need for further exploration into the prevention and treatment of postoperative complications following artificial joint replacement.
Osteotomy techniques such as high tibial osteotomy are primarily used for the treatment of KOA with varus and valgus deformities.
High body mass index is a risk factor for KOA. A previous study reported a 35% increase in KOA risk with every 5-unit increase in body mass index. This is primarily attributed to the fact that greater body weight increases the weight-bearing pressure of the knee joint, thereby increasing the probability of KOA
