The VMO, or vastus medialis obliquus, is the huge tear drop shaped thigh muscle, that lies just above and on the inner side of the kneecap, or patella. It is one of the four quadriceps muscles in the front of the thigh, but it is the only one that attaches directly to the inner (medial), upper margin of the patella. For this reason, it pulls inward on the kneecap and opposes the somewhat outer (lateral) pull of the other three muscles. The VMO is most active in the last 30 degrees of extension, meaning that it helps to lock the knee out, entirely straight. So, you may see that this one muscle has a strong influence on both the kneecap and knee stability, as a consequence of it is anatomy. Pain behind the kneecap commonly results from a direct blow or a fall, or it may result from maltracking, meaning that the kneecap is pulled off it is normal path, ordinarily to the outside (lateral side), and ofttimes because the VMO is weak and can’t counteract the pull of the other three quadriceps. Usually, this is accompanied by tightening or contracture of the soft tissues on the outer side (lateral side) of the kneecap, which makes it much harder to treat and rectify the problem. Some combining of these elements is commonly involved in kneecap pain, which may also be accompanied by instability, or giving way of the knee. Over time, these elements may result in degenerative softening of the cartilage beneath the kneecap, a sickness called chondromalacia patellae. The other major source of pain in the knee comes from within the joint, either from a twisting injury that may hurt a meniscus, one of the cushions within the joint, or a sprain of one of the ligaments, or an effusion, or “water on the knee,” which results from inflammation of the lining membrane of the joint, the synovium. And, in the older population, degenerative arthritis within the joint is likewise a source of knee pain and instability. In each case, strengthening the VMO is critical to relieving knee pain and restoring knee joint stability. So, what exercises are best for doing that? Here again, we take our lead from the functional anatomy. Since the VMO muscle wholly straightens the knee, and is most active in the last 30 degrees of extension, we want to load the muscle within that range of motion, to beef up it. Isometric exercises, technically specified as muscle contraction without shortening, those done with the knee to a complete degree straight, may increase VMO tone and beef up it is tendinous attachments. For example, quad setting is done by tensing the straight leg, contracting the quadriceps, as hard as you can, for six seconds. This is peculiarly primary when you have a fresh injury, or in the primary few days after knee surgery. It adds strength, but without any motion of the joint. Similar in effect is straight leg raising. Lying on your back, with the opposite leg bent up (to straighten your spine, and relieve stress throughout the lower back), you tense your quads, and, while preserving the contraction, then tardily raise the straight leg up, to regarding 45 degrees. Then, tardily lower it again. To get started with, try for 3 sets of 15-20 repetitions. This, too, is an exercise that is very utile in the prompt aftermath of an injury, or surgery. Isotonic exercise is muscle contraction with shortening and what we commonly think of as exercise, with overt motion of the joint. This type of exercise may implement the resistance of bodyweight only, or further and added external resistance, like free weights, or an exercise machine. The simplest exercise is a quarter squat. With or without weights, with your back versus the wall, plainly squat down just a quarter of the way, approximating when it comes to 30 degrees of knee flexion, then stand straight and tense the quads strongly. Even full range movements, like Full Squats or Hindu Squats, may be converted to VMO strengthening exercises by that isometric tensing of the quads, with the knee to the full or entire extent straight, with each repetition. My personal bestloved for working the VMO is the Hack Squat. In this exercise, you hold a barbell or two dumbbells behind your knees and leaning backward to put maximal stress on the VMO, do quarter squats. It’s helpful to have a wooden block underneath your heels to support with balance. Machine exercises are also useful, but leg press machines are in all probability better for your knee than leg extension machines, because the leg press loads your knee from above, and is more physiological (a “closed chain” exercise). This is particularly true if you have kneecap disease, like chondromalacia patella, or patellofemoral arthritis. Here again, you may handle very heavy weight eventually, because you’re using it for a very short arc, just 30 degrees. Whatever exercises you choose, you will start out to detect an betterment in your pain and your stability within when it comes to 10 days, and real betterment within 30 days. As the VMO becomes stronger, your patella tracking will improve and your knee will subjectively feel more stable. Although this regimen can’t heal everything, it may go a long way toward making your knees feel better and stronger. Give it a try.

He designed these same types of blades for the legendary but now defunct Camillus. Ka-bar was wise to ask him on board and he continues his basic approach – bringing people Busse-style ultra-thick high-quality steel fixed blades to those of us who don’t want to shell out $450 for a used Ash-1 on Ebay or $275 for a Tom Brown Tracker. The Ka-Bar Becker BK2 Companion is easily in their league. The Kydex shealth is excellent too – the knife snaps into it without even using the snap on belt and it’s much tougher than leather and will not retain moisture. More lanyard holes than you could possibly need too. I ordered my Becker Companion through Goliath and it came two days ahead of schedule. I cannot emphasize this knife enough. It is the survivalist’s survival knife. It is not a short sword or a silly Rambo knife. You can baton through a piece of steel pipe and then go skin a rabbit or fillet fish or whittle an oak spear with this knife if you so choose. I think that sums it up pretty well. Indestructible yet tractable. 80 of 81 people found the following review helpful. The pricing here on Amazon is about as good as I have been able to find- I think I paid maybe a dollar or two less for mine from another website. Including shipping you should not spend more than $65 on this knife, which sets it even further apart as being an outstanding buy. If you do some research, you will quickly find that comparable knives go for at least $200. Get the Bk2, you will not be disappointed. 80 of 86 people found the following review helpful. |
