Human beings are well designed for many things. We have large brains for poetry and quantum mechanics; we are good long distance runners, and of course have these awesome opposable thumbs. Unfortunately, some parts are not designed very well for our 21st century lifestyles. The low back , or lumbar spine, is first on my list for sending back (or forward?) to the engineers. A close second though might be the " knee cap " or patellofemoral joint.
The "knee cap" or patella is an ovoid shaped bone whose main purpose is to act as a fulcrum that big muscle on the front of your thigh, the quadriceps. (I'll wait while you grab your high school physics book). There are plenty of folks who do not have patellae, but because this causes the quad muscle to work inefficiently, few of these folks can run or climb stairs well. The design issue with the patella is that it articulates, or rubs up against, the end of the femur bone (thus the "patellofemoral" joint). For those of us who have pa...
Why is it that most running injuries occur at the knee or in the lower leg? Is there some common factor that might be involved? The authors of this study set out to look for some answers to these questions. They didn't do a study themselves of runners. Instead they turned to the literature and did a search of all the published articles on running injuries. Research studies like this are possible now that everything is contained within an electronic database. Four of the most well-respected electronic databases (e.g., MEDLINE, EMBASE, PsychoInfo, CINAHL) were accessed for information on risk factors for overuse running injuries. By doing a search with words like running , injury , mechanics . and knee , they were able to find 283 articles on running injuries published between 1980 and 2008. They narrowed the search down by looking for running injuries in long-distance runners who ran at least 20 kilometers (12 miles) each week. The athletes were recreational or competitive runners (not elit...
Knee scope - arthroscopic lateral retinacular release; Synovectomy; Patellar debridement
Expectations after surgery
Use of arthroscopy has reduced the need to surgically open the knee joint. This has resulted in less pain and stiffness, fewer complications, decreased length (if any) of hospitalization, and faster recovery time. Expectations vary widely with the indication for the surgery.
Surgery done for a meniscal tear or loose bodies when the patient has no other problems (like arthritis) is usually uncomplicated, and most patients can expect a full recovery. The presence of arthritis dramatically reduces the effectiveness of arthroscopy and up to 50% of patients may not improve post-operatively.
Arthroscopic removal of the synovium (arthroscopic synovectomy) can be of great benefit to patients with rheumatoid arthritis. Arthroscopic or arthroscopic-assisted surgery done to repair the meniscus or reconstruct ligaments in the knee is much more...
