It Hurts When I Bend my Knee: Osteoarthritis Knee and What I Can Do Next

The knee, a joint that is central to our ability to walk, bend and stand, is easily one joint that we use most in our day-to-day functioning. When your knee gets inflamed, you will experience pain, swelling and stiffness. There may be two main reasons for pain. Characteristics of the first type of pain would be sudden and spontaneous, and the causes stem from different reasons such as a Fracture, Tendinitis, Bursitis, Injured Menicus and Gout.

More commonly, people suffer from pain as a result from degeneration or wear-and-tear, which is primarily Osteoarthritis. This is a condition when the cartilage between the joints wears away and the rubbing results in pain, swelling, stiffness, decreased movement and occasionally bone spurs.

What is Knee Osteoarthritis (OA)?

When the lubricating layer, which is the cartilage, wears away, the bones end up rubbing directly against each other causing friction, which in turn results in pain and disability. Symptoms that point to this problem will be when pain increases with activity (more movement, more friction) and if you experience swelling, stiffness at the joint while having difficulty with simple tasks like getting in and out of cars or walking.

Do I have to go to a doctor? – You may ask. There are certainly measures you can adopt on your own before heading to the clinic, but it may take awhile before improvements can be felt. Self-treatment methods include weight-loss (to reduce load on the knees), strengthening the muscles around the knee (increasing muscular ability to support weight) and taking supplements such as glucosamine. Hot and cold compresses can be used for immediate relief, but the pain would likely recur as the problem has not been tackled at the root.

While these methods are important, they are more effective with the advice of a medical practitioner.

Common treatments for Osteoarthritis Knee

Fortunately, there is a plethora of treatment options for the Osteoarthritis Knee patient. In no particular order, here are some options that people turn to.

  • Medication

Pain relievers include analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs). Some are available over the counter while others need a doctor’s prescription. Occasionally, antidepressants such as duloxetine (Cymbalta) and anti-seizure drug pregabalin (Lyrica) may be used to treat Osteoarthritis Knee pain.

  • Injections

A corticosteroid injection works in a similar way as a hormone called cortisol. Injected straight to the joint, the jab seeks to reduce inflammation in the area. A platelet-rich-plasma (PRP) injection helps ease pain and inflammation, while healing the region. Lubricants such as hyaluronic acid can also be injected to provide cushioning at the joint.

  • Physical Therapy

Physical, occupational therapists and chiropractors can provide specific exercises to help improve joint stability and ease pain while giving advice on movements that will protect joints and enable smoother mobility. They may also prescribe the use of braces, shoe inserts or assistive devices to aid motion.

  • Surgery

A joint surgery aims to replace the damaged joints through Arthroplasty. Here, your surgeon removes your damaged surfaces and replaces them with plastic or metal parts. Risks of this surgery include infection and blood clots, and the artificial joints may eventually wear out and need to be replaced. In knee Osteotomy, the surgeon cuts across the bone either above or below the knee and adds a bone wedge in order to shift the body weight away from the worn-out part of the knee.
