Osteoarthritis of the knee : stage, diagnosis, and treatment

Hello!! And welcome to the One Care Medical Center one of Coimbatore’s premier international orthopedic hospital, My name is Dr. Abdul Salam and I am a full-time orthopedic surgeon at OCMC. In today’s short blog post we are going to discuss about

Osteoarthritis (OA) is a very common condition that affects the knee joint. It affects a large portion of men and women after 50 years of age.

In OA knee, degeneration of joint cartilage takes place, along with inflammatory changes in the synovium (soft lining of the joint tissue)

As the protective function of both the cartilage and synovial lining break down, they can no longer protect the joint. Thus, damage occurs.

OA of the knee presents itself with well-known symptoms. These are pain and stiffness. Moreover, these symptoms worsen over a period of time.

OA of the knee proceeds in stages and symptoms usually worsen with disease progression. Moreover, in some patients symptoms may not manifest until a very late stage disease.

Let us look at the various stages of OA knee

Stage 1

Patients in stage 1 OA knee are unlikely to feel any specific symptoms as such. There will be no joint space narrowing too. The X-ray appearance will also be normal.

In this stage of the disease, small lumps of bone called osteophytes may grow in the knee joint area.

Stage 2

This stage is the symptomatic stage of the disease, where the patient may feel his knee is stiff and uncomfortable after sitting for a prolonged period of time. X-Rays usually show much more osteophyte growth as well. Cartilage thinning also begins.

Stage 3

Narrowing of the bone gap occurs and X-rays shows loss of cartilage. Daily activities also elicit significant pain. There may be signs of joint inflammation and also daily activities like running, walking, bending all cause significant discomfort.

Stage 4

Stage 4 is the most advanced stage of OA knee, symptoms are clearly visible. Joint space narrows severely. There is more inflammation and stiffness in the joint. An X-ray may show bone on bone with complete loss of protective cartilage.

Treatment Options

Here the symptoms are mild, so over the counter medications can be used to relieve pain. Physiotherapy can be done to build joint strength and mobility. Medications like Chondroitin sulfate may help
Patients can
A. Take painkillers
B. Chondroitin sulfate
C. Wear a knee brace A combination of the above strategies with some lifestyle changes may work best.
Treatment strategies can include the use of 3 to 5 hyaluronic acid injections over a 3-5 week period. Relief from these treatment strategies can last for about 6 months.
Patients, cartilage has disappeared. The person may require joint replacement.
