Knee Osteoarthritis is a multifactorial health condition that is incurable. It is a condition in which the natural lubricant between the joints cartilage wears away causing to rub the bones of the joins more closely against one another leading to pain, discomfort, inflammation, swelling, etc. in the joints.

  • Moderate pain while resting or throughout the day. 
  • Medicine resistant long-lasting inflammation and swelling even after using proper rest/relaxation techniques.

Is there no cure for OA other than surgery?

OA cannot be cured completely, but existing treatments can reduce pain and suffering and help in better mobility.  It includes

  • Medications: To relieve the pain

a) Acetaminophen: The drug has been used to help relieve pain for people suffering from mild to moderate osteoarthritis pain. 

b) Nonsteroidal anti-inflammatory drugs (NSAIDs): Drugs such as ibuprofen (Advil, Motrin IB, others) and naproxen sodium (Aleve, others), on recommended dose consumption, are known to relieve osteoarthritis pain. 

c) Duloxetine (Cymbalta). It is an antidepressant, also approved to treat chronic pain, is also used to treat osteoarthritis pain.

b) Occupational therapy: It can help to discover different ways to carry out daily routine/tasks without putting extra stress on the painful joint. 

  • Injections

a) Cortisone injections: They are used to relieve pain in the joint. They are given directly to the affected joint. One can receive a maximum of 3-4 injections in a year, above that is not advisable by the doctor as it worsens the joint damage. 

b) Lubrication injections: These help to provide some cushioning to the knee joint. 

Knee Replacement Surgeries

When the above mentioned medical treatments fail to provide relief to the patients, knee replacement surgery may be considered as an effective treatment.

The goal of knee replacement surgery is to relieve knee pain by resurfacing the parts of the knee joint that have been damaged due to various reasons. Studies have proved that knee replacement surgeries have helped the individual to be able to lead a better quality of life with no discomfort or pain following the procedure.

Is there any risk involved in knee replacement surgery?

With recent technological advancements, the surgery involves almost no complications. However, in some cases, the patient may face issues such as:

  • Bleeding
  • Infection
  • Blood clots in the legs or lungs
  • Loosening or wearing out of the prosthesis
  • Fracture
  • Continued pain or stiffness
  • Loose knee joints post-surgery
  • Weakness or numbness due to injured nerves during surgery

The good news is that almost 90% of knee replacement surgeries are successful with little to no complications post-surgery.

  • Frequent breathing exercises
