Your wife has early osteoarthritis, which means the smooth cartilage in her knee joints is gradually wearing out, leading to pain and stiffness. In the early stage, treatment usually focuses on improving daily function rather than on injections or surgery alone. Regular physiotherapy exercises to strengthen thigh muscles, maintaining a healthy body weight, and using simple pain-relief medicines when needed can make a big difference. Hyalone injection (Hyaluronic acid) is used to improve lubrication and reduce friction inside the knee joint, which may help ease pain and improve movement in some people with mild to moderate osteoarthritis. However, the benefit can vary from person to person, and it also does not reverse the damage or cure the disease. The injection is generally safe when given by a trained doctor in a medical setting. Some people may feel temporary pain or swelling after the procedure. It is not advised if there is an infection in the joint or advanced arthritis. It is best for your wife to be assessed by an orthopaedic specialist first, who can examine her knees and then suggest the most suitable treatment plan.
