The New Informative Guide for Risks in Knee Replacement

Risks in Knee Replacement

It is rare for someone with a knee replacement to experience serious complications. But like any other surgery, a knee replacement also has risks as well as benefits. It is always better to have an understanding of what could cause a complication during or after a knee replacement surgery to help yourself and your doctor to keep safe.

You have read the previous article about 47-year-old Rakesh who underwent a partial knee replacement recently and is now in the recovery phase. Rakesh is a sports lover and loves playing squash. Rakesh did not face any such problems during or post his surgery as he was well prepared with all the required tests and precautions that were needed to avoid any complications.

The two points mentioned below are very severe possibilities of complications that can occur after a knee replacement surgery. You must immediately report to your doctor in case you face any such discomfort.

Risk with Anaesthesia

  • If you develop hot, hard and reddened painful areas in your legs in the first few weeks post your surgery. There are chances that it may just be bruising from the surgery, or could be a blood clot.
  • Chest pain or breathlessness – This happens in rare cases like 1 in 100. A clot can form on your lung which is called (pulmonary embolism). This can be severe if ignored. It must be treated urgently.

Risk with Anaesthesia

Anesthetics are very safe, but we cannot ignore the fact that they do carry a partial risk of minor side effects such as sickness and temporary confusion. The risk of death in a healthy person having routine surgery is very rare as one in every 100,000 cases. The risk is higher only if you’re older or if you have other health conditions, related to the heart or lungs.

Other complications

Complications in a knee replacement surgery are very rare and most are minor.  These can be successfully treated. Below are some common complications that may occur.

  • Wound infection:  This is treated with antibiotics with which it usually recedes, but sometimes the wound can get infected deeply. This would require further surgery with by replacing the artificial knee joint.
  • The ligament, artery or the nerve  around the knee joint can get damaged.
  • Blood clots may form in the leg veins lowering the movement in the leg during the first few weeks after surgery.
  • Clotting can be prevented by using anticoagulant medicines.
  • starting to walk or exercise immediately after the surgery.
  • Unexpected bleeding into the knee joint.
  • Excess bone formation around the artificial knee joint restricts the movement of the knee requiring further surgery to  remove the extra growth and restore movement of the knee
  • Dislocation of the knee cap or the patella bone: A minor surgery can be done to repair this.
  • Allergic reaction: You may face an allergic reaction to the bone cement if you are allergic to some medications.

Preparing for surgery

Complications in a knee replacement surgery

It is very important to be as active as you can. Gentle exercises like walking help in strengthening the muscles. Months before your surgery, your physiotherapist may give you exercises that relax the muscles around your knee.

Some things that contribute to having a smooth surgery include:

  • Getting a complete medical checkup before the surgery, including all blood and urine tests, x-ray, ECG, and any other tests that make sure you are healthy enough to undergo a knee replacement surgery.
  • Your doctor’s advice regarding any medications you might need to stop or need to be replaced by alternatives before the surgery plays a vital role. These medications could include some medications for rheumatoid arthritis, as they suppress the immune system resulting in affecting the recovery process.
