Knee Arthritis: Types, Symptoms, Causes & Treatments
30 Nov -0001

Normal Knee Anatomy

Having healthy knees is vital to carrying out day-to-day chores. Our knee is the largest joint in the body and comprises three parts: the femur, tibia, and patella. The femur is the lower end of the thighbone. The tibia is the upper end of the shinbone, and the patella is the kneecap. A smooth substance known as articulate cartilage protects the ends of these bones and allows the leg to move comfortably.

Between the femur and tibia, c-shaped wedges, aka menisci, act as “shock absorbers” that shield the joints. Not only this, there are large ligaments that hold the femur and tibia together and provide strength and stability to the knees. 

A synovial membrane covers all the left sections of the knee. This membrane is a thin lining and releases a fluid that polishes the cartilage, lessening the friction in a healthy knee.

Typically, these components work in accordance. However, if it gets infected by some disease or injury, the outcome will be painful, and the muscle will get weak and diminish its functioning.

What is knee arthritis?

Arthritis is an illness that results in swelling, stiffness, and pain in the joints. Arthritis can harm even the strongest and largest body joints. Knee arthritis is very common and can be a weakening and severe ailment. 

Types of knee arthritis

There are numerous kinds of arthritis but the most common types that might influence the knee consist:-

  • Osteoarthritis: This knee arthritis is the most common one on the list. This wears away the cartilage that works as a cushion between the three bones of the knee joint. They help in protecting the bones to rub against one another. Without them, the knee movement gets slow, there remain pain and stiffness. This result in the evolution of bone spurs. As time pass, the osteoarthritis gets worse. 
  • Post-traumatic Arthritis: In this, the cartilage begins to thin after the knee gets into an accident or gets injured. The bone then starts rubbing one another and then give rise to the symptoms - limited movement, pain, and stiffness. 
  • Rheumatoid Arthritis: In the human body, a healthy immune system produces inflammation that prevent from toxins, injury, infection, or other foreign invader. When a person gets rheumatoid arthritis, the patient has an unhealthy immune system that set off inflammation in the joints without having any foreign invaders. Due to this, the synovial membrane gets swell, stiff, and sore.

Causes of arthritis in knee

According to the experts, human genes might be responsible for arthritis. One could have a gene connected to arthritis without any awareness and even an injury or come in contact with the virus can set off arthritis of the knee. Here is the list of causes of arthritis in knee:-

  • Age: Arthritis usually happens when a person starts getting older as compared to their young age.
  • Weight: The more a person gains weight, the more pressure will lead on the knee joints.
  • Stress: Activities that lead to stress in an individual body can also be responsible for arthritis in the knee. Activities that result in stress-playing sports, jogging, working on an active job, etc.
  • Gout: Gout is a kind of inflammatory arthritis that in the future can result in osteoarthritis.

Arthritis knee treatment

The treatment for arthritis in the knees can be divided into two categories - Non- surgical & Surgical:-

Non-surgical Treatment

The doctor always first suggests to their patients the non-surgical treatment before going for the surgical treatment. There is a range of treatment options in this treatment category.

Physical Therapy: Certain exercises help expand the range of flexibility and motion and also assist in building up the muscles in the leg. The physical therapist can make a customized exercise program that will be compatible with the patient’s lifestyle and necessities.

Lifestyle modification: Sometimes, the lifestyle of the patient is also the root cause of their knee arthritis. So, some changes in the lifestyle can actually protect the knee joint.

  • Reduce the activities that worsen the condition.
  • Weight gain can put stress on the knee joint. Make sure to lose some weight as it will lead to improve functions and reduce pain.
  • In order to put less stress on the knee, make sure to shift from high-influence activities to lower-influence activities. 

Medications: For treating knee arthritis, there are various kinds of drugs. As every patient reacts differently to different medications, the doctor will carefully examine the patient and determine the right medications and dosages that are effective and safe for them.

Other remedies: In order to provide some level of pain relief, the doctor can advise the patient to use pain-relieving ointments, put ice and heat, etc. 

Surgical Treatment

When non-surgical treatments fail to provide any relief to the patient, then the doctor switches to surgical treatment. 

Arthroscopy: Arthroscopy surgery is not usual in treating knee arthritis. But the treatment is done when there is osteoarthritis with a degenerative meniscus tear. In this process, the surgeon makes tiny cuts and puts some mini instruments to determine and cure the joint issues. 

Synovectomy: In this treatment, in order to lessen the swelling and pain, the surgeon removes the joint lining that got damaged by rheumatoid arthritis.

Arthroplasty: In arthroplasty, the surgeon separates the injured bone & cartilage and places the plastic joint surface to reinstall the knee‘s functions.

Cartilage grafting: Cartilage grafting is a treatment that generally comes into the thought only when there are younger patients that have cartilage damage in small areas.
