A trick knee, also called a locked knee, refers to a knee that locks or stiffens while walking, bending or doing other forms of movement and exercise. A trick knee is due to a meniscal tear which, according to the American Academy of Orthopedic Surgeons, is one of the most common knee injuries. Some exercise may not be tolerated well with a trick knee, so get your doctor's approval when planning an exercise routine.
Consideration
The knee, a hinge joint, is the largest joint in the body. It depends on surrounding muscles, such as the quadriceps, hamstrings and calf muscles, to protect it from damage. Nonetheless, common causes of meniscal tears or a trick knee are vigorous activity like intense exercise that involves a lot of bending and twisting, or sports. This is why not all exercise benefits a trick knee.
Exercises
It helps to remember that simple is best when dealing with a trick knee. There are three general exercises to strengthen muscles around your knee. To do quad sets, sit on the floor with your leg extended outward; tighten the quad muscles for several seconds and release. Do hamstring curls by lying on your stomach and bending your leg back. If this does not cause any discomfort, add an ankle weight. Finally, do calf exercises by holding on to the back of a chair and slowly raising your heels to stand on your toes; repeat.
Stretching
Stretching is important for maintaining knee strength because tight calf and hamstring muscles can make you walk in a way that puts pressure on the knee. Do stretches when the body is warmed up . Sit on the floor with both legs extended, and slowly lower the torso to reach for the toes. Hold for several seconds and release. Never bounce while stretching. Accomplish slow and smooth movements, and never force flexibility that does not yet exist. Stop stretching immediately if you feel any knee discomfort.
Expert Insight
For further knee support, consider using a knee brace while exercising or playing sports. In the ABC News health article, "When Should I Consider Using A Knee Brace When I Play Sports, And How Should I Use It?", Dr. Neal Chen suggests using a knee brace as soon as you begin to feel discomfort in your knee or experience occasional clicking and swelling. If the pain is persistent, see a doctor to find out if you need surgery.
