General Knee Surgery FAQ's
1. GENERAL FAQ’S
Arthritis is a general term for conditions that cause inflammation and pain in the joints. The most common types affecting the knee are osteoarthritis and rheumatoid arthritis. Osteoarthritis is a degenerative condition where the cartilage in the knee joint wears down over time, leading to pain, swelling, and reduced mobility. Rheumatoid arthritis is an autoimmune disorder that causes the immune system to attack the lining of the joints, resulting in inflammation, pain, and joint damage. Both types of arthritis can significantly impact daily activities and quality of life.
Osteoporosis is a condition characterised by weakened bones that become brittle and more prone to fractures. It occurs when the creation of new bone doesn’t keep up with the removal of old bone. This condition is more common in older adults, especially postmenopausal women, due to decreased levels of hormones that protect bone density. While osteoporosis primarily affects the bones, it can complicate joint conditions like arthritis by making bones more susceptible to fractures and affecting the overall health of the knee joint.
While it’s possible for a knee to become severely damaged, advancements in surgical techniques have made knee replacement surgery viable for many patients with advanced knee degeneration. However, severe deformities, extensive bone loss, or certain medical conditions might complicate the procedure. Early consultation with an orthopaedic surgeon like Dr Martin can help determine the best treatment plan. Even in cases of significant damage, there are often surgical and non-surgical options available to improve function and reduce pain.
2. PRE-SURGERY FAQ’S
For knee surgery, you can typically choose between a combination of local, regional, or general anaesthesia. Local anaesthesia numbs only the knee area, regional anaesthesia numbs the lower half of the body (such as a spinal or epidural block), and general anaesthesia puts you to sleep for the duration of the procedure. The choice of anaesthesia depends on your overall health, the specific procedure, and your preferences. Dr Martin and the anaesthesia team will discuss the best option for you to ensure your comfort and safety during surgery.
Yes, exercising before knee surgery can be beneficial. Preoperative exercises, often referred to as “prehabilitation,” can help strengthen the muscles around your knee, improve flexibility, and enhance overall fitness. This can lead to a smoother recovery and better postoperative outcomes. Dr Martin or a physiotherapist can provide you with specific exercises tailored to your condition and physical capabilities.
Quitting smoking before surgery is crucial for several reasons. Smoking can impair blood circulation, reduce oxygen levels in your blood, and slow down the healing process. It also increases the risk of complications such as infections, poor wound healing, and anaesthesia-related issues. By quitting smoking, you can improve your overall health, enhance your body’s ability to heal, and reduce the risk of surgical complications. Dr Martin strongly advises patients to quit smoking well in advance of their surgery.
There is a very small risk of infection getting to your new knee months or years after surgery. Dental work is one way this can happen. Antibiotics before dental work or other invasive procedures can help with this. In general, it is recommended to put of non-urgent work until 3 months or more after knee replacement. It is important to inform your dentist or healthcare provider about your knee surgery and follow the recommended precautions.
