FROM OUR EXPERTS
About two months ago, I injured myself during kickboxing. I think I was doing a squat and turned my knee inward.
My knee hurt afterward, but I figured that maybe once I had my next dose of Humira, it would feel better. This was kind of nonsensical because while I’ve had knee pain with my arthritis, it hasn’t been one of the more significant areas of my body impacted by my arthritis.
So I let it go. My Humira dose came and went, and my knee still hurt.
I wasn’t really paying that much attention to the knee pain, but the kicker (no pun intended) was when, in another episode of kickboxing, I did a side plank (if you don’t know what that is, see: http://www.mayoclinic.com/health/core-strength/SM00047&slide=12 ), putting all of my weight on my knee, and it completely collapsed.
After a week of the pain getting worse, I went to the doctor, and was told that I had misaligned my kneecap. I was sent to p...
Q: My knee just started hurting three weeks ago out of the blue. Before that, I didn't have any pain. My doctor told me I have osteoarthritis. I thought osteoarthritis was a chronic problem. Can it happen all of a sudden? Is my doctor wrong about my diagnosis?
Osteoarthritis is indeed a chronic process. It is not a condition that just happens "all of a sudden." However, in certain situations the symptoms of osteoarthritis can occur suddenly. It is similar to cholesterol or high blood pressure causing a heart attack. High cholesterol and high blood pressure don't "feel bad." But high cholesterol and high blood pressure do lead to fatty plaque deposits in the arteries. One day, while running for a cab, the heart may need an increased amount of blood supply but the red blood cells can't get past the stiff, fatty plaques fast enough and so the heart is starved of oxygen. "All of a sudden" chest pain develops.
In a similar vein, joints tend to lose cartilage slowly over time...
Imagine that after years of painful knee symptoms, you have a total knee replacement (TKR). Ahhh, relief at last! But within a couple of months, the knee starts making a loud "clunk" every time you straighten it from a fully bent position. The problem could be the patellar clunk syndrome. This syndrome occurs when a fibrous nodule develops on the back of the kneecap (patella). When the knee bends, this fibrous bump gets trapped within a notch in the surface of the thighbone (femur). (The bottom of the femur meets the top of the tibia in the lower leg to form the knee joint.) As the knee straightens, the bump moves out of the notch. Knee pain and a "crunching" sound occur as the patella moves against the femur. At the same time, a "clunk" is usually heard. Doctors think that two factors cause the patellar clunk syndrome: the design of the joint implant (on the femoral side) and the patient's knee-flexion angle. Generally, only patients with more than average knee flexion get this proble...
