Originally, total knee arthroplasty (TKA), or replacements, were for older people who had often begun to slow down or limit physical activities. However, the population of patients undergoing TKA is getting younger and more active - and more ethnically and culturally diverse, requiring the ability to flex the replacement in ways previously not needed. The authors of this study wanted to identify articles in the literature that reviewed the postoperative range of motion of TKA. Among the articles one reviewed TKAs for stiffness and flexion (bending) contracture before the surgery. The findings of that study were that the more limited the flexion and the stiffer the joint before surgery, the more reduced the flexion would be after surgery. Another study, looking at physiotherapy after surgery, determined that postoperative physiotherapy was particularly important, especially now that hospital stays after surgery are shorter than they have been in the past. The study also notes that the ef...
A popular method used to repair anterior cruciate ligament (ACL) tears is the hamstrings tendon graft. Specifically, a piece of the semitendinosus-gracilis (STG) portion of the hamstrings is used to replace the ACL. The hamstrings help flex (bend) the knee. In this study, knee flexion strength is measured two years after the ACL repair. Earlier studies have shown that knee flexor strength is reduced for the first month after surgery. More recently other studies have shown longer-term weakness related to STG tendon harvest. In this study twenty (20) patients of one knee surgeon were included. Joint motion, function, sensation, and joint laxity (looseness) were measured after surgery. Patients were tested in the prone (face down) position to allow as much knee flexion as possible. Joint range of motion and muscle strength were measured. The results showed loss of motion and decreased flexor strength two years after ACL reconstruction with an STG graft. The patients' perception of normal s...
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...
