You aren’t able to move as freely as you once did. Walking the dog, climbing a flight of stairs, or simply getting out of a chair is excruciating. Medicines, injections, and physical therapy have all been tried. You feel excruciating knee pain at night, and nothing seems to work. If this is the case, knee replacement surgery may be necessary.
| DID YOU KNOW?In the United States, over 600,000 knee replacement surgeries are performed each year. The majority of patients are between the ages of 50 and 80. Over 90% of patients report a significant improvement in pain and mobility. |
Knee replacement surgery (or Knee Arthroplasty) procedure is one of the most common orthopaedic surgeries across the world.
It is a surgical procedure that resurfaces a knee damaged by overuse or conditions like arthritis. During the surgery, the damaged part is removed and replaced with a prosthetic (artificial joint), which is then connected to the thigh bone, knee cap, and shin. The materials used are a combination of medical grade metals such as Titanium and Cobalt Chrome in addition to highly cross linked Polyethylene.
| GOAL of the surgeryThe goal is to get rid of the pain and regain mobility. |
Osteoarthritis is the most common condition that necessitates knee replacement surgery. Apart from this, degeneration of the knee joint due to overuse or rheumatoid arthritis can lead to the need for knee replacement surgery. Besides, fractures, torn cartilage, and torn ligaments can also cause irreversible damage to the knee and may call for a surgical intervention.
The recommended first line of treatment usually includes anti-inflammatory medications, physical therapy, cortisone injections into the knee joints, or weight loss treatments. Surgery is only recommended when these treatments prove ineffective, and the symptoms deteriorate the patient’s quality of life.
Knee replacement generally requires staying in hospital on average 2.5 days. Procedures may slightly differ depending on your condition. On some occasions, it maybe possible to leave hospital within 24h.
Knee replacement surgery is usually done under spinal anaesthesia. Patients also receive sedation so you are asleep throughout the procedure.
An intravenous (IV) line is initiated in your hands or arms. After lying on the operating table, a urinary catheter may be inserted. Hair at the surgical site that is excessive may be clipped off.
During the surgery, the anesthesiologist will keep track of your heart rate, blood pressure, breathing, and oxygen level.
Moving further in the procedure, a knee incision will be made by our orthopaedic surgeon.
Our surgeon carefully resurfaces the knee joint with the prosthesis after removing the damaged surfaces. Then, the surgeon places the knee prosthesis using robotic-assisted arms to ensure the highest level of precision with sub-millimetre accuracy. A cemented prosthesis is the most common type of artificial knee prosthesis. Surgical cement is then used to secure the cemented prosthesis to the bone.
Finally, the incision is stitched or stapled closed carefully. The operated area is dressed with sterile bandages.
The surgery typically takes between 1.5-2 hours. After a short spell in the recovery area, patients return to their room and are allowed to start eating and drinking.
However, consult our doctor right away if any of the following instances catch your attention:
