Torn Cartlidge in knee is improving steadily

Torn and reparied meniscus is improving steadily.

I feel very comfortable playing baseball, turning and stoping for the ball. I still do not put over 60% of my weight on the knee when using it in these situations. I do let some balls go that would call for a full weight bearing turn on the knee. I am able to mow and play ball with out limping on the knee now, but it still swells slightly. I do not use stairs, as this still puts presure on the knee when it bends from step to step (I do go up and down a flight of stairs about once daily).

I will be posting artilces about knee pain, prevention, and products that I have reviewed and feel they will benefit the reader.

If you've ever injured your knee, you're not alone. Knee injuries have actually become pretty common. One of the main reasons they're common is that with so many teens playing sports, knees can be overused, leading to several types of injuries, some of which can't be repaired. So what are some of these knee injuries and what can you do to prevent them?
What's in a Knee?To understand knee injuries, first you have to understand the knee. The knee is a joint, which means it sits between the area where bones connect. It's actually the largest joint in the body. Your knees provide stability and flexibility for your body and allow your legs to bend, swivel, and straighten. The knee is made up of several body parts like bones, cartilage, muscles, ligaments, and tendons, all working as one. So when we talk about a knee injury, it could be stress or damage to any of these parts.
Bones and CartilageThe knee sits in the middle of three bones: the tibia (your shin bone), the femur (your thigh bone), and the patella (the knee cap). The patella is a flat, triangular bone that protects the knee joint.
The ends of the femur and the patella are covered in articular cartilage. Articular cartilage acts like a cushion and to keep the femur, patella, and tibia from grinding against each other. On the top of the tibia, extra pads of cartilage called menisci help absorb the body's weight (if you're talking about one, it's called a meniscus). Each knee has two menisci - the inside (medial) meniscus and the outside (lateral) meniscus.

MusclesThe muscles in the knee include the quadriceps, a large muscle at the front of the thigh, and the hamstring, which is located at the back of the thigh. The quadriceps muscle helps you straighten and extend your leg, and the hamstring helps you bend your knee.
Tendons and LigamentsSeveral tendons and ligaments work together to help the knee move naturally.

Tendons are like cables of strong tissue that connect muscles to bones. The tendons in the knee are the quadriceps tendon and the patellar tendon. The quadriceps tendon connects to the top of the patella (kneecap) and allows you to extend your leg. The patellar tendon connects to the bottom of your kneecap and attaches to the top of the tibia (shinbone).
Ligaments are like cables of strong tissue that connect bones to bones or cartilage to bones. There are four ligaments in the knee that help connect the femur to the tibia and keep your legs stable:

medial collateral ligament (MCL) - The MCL connects your femur to your tibia along the inside of your knee. It keeps the inner part of your knee stable and helps control the sideways motion of your knee, like keeping it from bending inward.

lateral collateral ligament (LCL) - The LCL connects your femur to your tibia along the outside of your knee. It keeps the outer part of your knee stable and helps control the sideways motion of your knee, like keeping it from bending outward.

anterior cruciate ligament (ACL) - The ACL connects your femur to your tibia at the center of the knee. It helps control forward motion and rotation, like keeping your shinbone from sliding out in front of your thighbone.

posterior cruciate ligament (PCL) - The PCL connects your femur to your tibia at the back of the knee. It helps control the knee's backward motion, like keeping the shinbone from sliding out under the thighbone.

Types of Knee InjuriesNow that you know all about its working parts, you probably realize that there are a bunch of ways to injure a knee. Common causes for injuries are overuse (from repetitive motions, like in many sports), sudden stops or twists, or direct blows to the knee. Here are some of the more common injuries:

SprainsA sprain means you've stretched or torn a ligament. Common knee sprains usually involve damage to the ACL and/or MCL. The most serious sprains involve complete tears of one or more of the knee ligaments. Symptoms of knee sprains include:
a popping or snapping sound in the knee at the time of injury
pain that seems to come from within the knee, especially with movement
not being able to put any weight on that leg, swelling, fluid behind the kneecap,
the knee feels loose or unstable.

StrainsA strain means you've partially or completely torn a muscle or tendon. With knee strains, you may feel symptoms similar to a sprain and may see bruises around the injured area.
TendinitisTendinitis happens when a tendon gets irritated or inflamed. It is often caused by overuse. A person with tendinitis might have pain or tenderness when walking, or when bending, extending, or lifting a leg.

Meniscal TearsDamage to the menisci is a really common sports injury, especially in sports where sudden changes in speed or side-to-side movements can cause them to tear. Meniscal injuries often occur together with severe sprains, especially those involving the ACL. Meniscal injuries can cause tenderness, tightness, and swelling around the front of the knee. Sometimes fluid collects around the knee (this is called effusion).

Fractures and DislocationsA fracture is a cracked, broken, or shattered bone. You may have trouble moving that bone and it's likely there's a lot of pain. Patellar dislocation happens when the patella (the kneecap) is knocked off to the side of the knee joint, by twisting or some kind of impact. Sometimes it will go back to its normal position by itself, but usually it will need to be put back into place by a doctor. Symptoms include swelling and a lot of pain at the front of your knee. There will usually be an abnormal bulge on the side of your knee, and you may be unable to walk. Cartilage InjuriesSometimes a small piece of bone or cartilage softens or breaks off from the end of a bone, causing long-term knee pain. This is called osteochondritis dessicans (OCD). Symptoms of OCD include pain, swelling, an inability to extend the leg, and stiffness, catching, or popping sensations with knee movement. Treatment can include resting the knee, wearing a cast for a couple of months, and sometimes surgery in older teens. Chondromalacia happens when the cartilage in the knee joint softens because of injury, muscle weakness, or overuse, and the patella and the thighbone may rub together. This causes pain and aching, especially when a person walks up stairs or hills. Treatment may involve surgery.

Other Conditions of the Knee

BursitisA bursa is a sac filled with fluid located near a joint. If a bursa in the knee becomes inflamed and swollen from overuse or constant friction, it can develop into a condition called bursitis. Symptoms of bursitis in the knee include warmth, tenderness, swelling, and pain on the front of the kneecap.

Osgood-Schlatter DiseaseOsgood-Schlatter disease is a painful disorder caused by repetitive stress on the front end of the tibia where the patellar tendon connects to the bone. It happens most frequently in young athletes between the ages of 10 to 15 years. Symptoms include a bump below the knee joint that's painful to the touch and is also painful with activity. Pain is relieved with rest.

What Do Doctors Do?There are different things a doctor may do to figure out whether you have a knee injury. Treatment for a knee injury usually depends on the type of injury you have.
First, your doctor will ask you questions about your symptoms, including what your usual activities are, especially any sports you play. The doctor will also want to know about other health conditions that lead to knee pain.

The doctor will then examine the different parts of your knee, checking the bones, ligaments, and tendons for any signs of injury. The doctor will probably bend, twist, and turn your knee to look for any signs of an unstable knee joint. Don't be surprised if you're asked to get off the exam table and walk, bend over, or squat so your doctor can get a better look at your knee. Sometimes an X-ray of your knee is needed to get a good picture of your bones. A CAT scan or MRI may also be recommended so doctors can get a better three-dimensional picture.
For injuries like mild sprains, strains, and overuse, resting your knee may be one of the first treatments your doctor recommends. Remember RICE:

Rest
Ice
Compression
Elevation

If your doctor recommends RICE, you should rest your knee as much as possible, use ice packs for a couple of days to bring down swelling, use compression (ACE) bandages, and elevate the leg on pillows or other soft objects. For inflammation and pain, your doctor may prescribe anti-inflammatory medications like ibuprofen.

Other treatment for knee injuries may involve using a knee immobilizer (kind of like a brace or a sleeve that you wrap around your leg to keep it from moving too much), or having to wear a cast for a few weeks or months. You may also have to use crutches to get around for awhile.
For more serious knee injuries, your doctor might recommend you see an orthopedic surgeon, a doctor specially trained in the care of bone and joint diseases (also called an orthopedist). Orthopedists take care of many kinds of knee injuries, especially those involving sports and different types of accidents. He or she will know how to treat the injury and follow your progress as it heals.

ArthoscopyIf necessary, an orthopedist will perform arthroscopy, a type of surgery that takes a direct look at the inside of your knee joint.
During arthroscopy, the orthopedist first makes a small opening in the knee and inserts an arthroscope, a tiny tube-like tool, into the joint capsule. The arthroscope contains a lighted video camera on the end, and is wired to a television screen that the surgeon watches while moving the scope to pinpoint the exact knee problem. Most of the time, the doctor is able to fix the problem during the procedure, like repairing a torn ACL ligament.

Arthroscopy is often used to treat knee injuries such as ligament and meniscal tears, as well as other types of serious knee injuries. An orthopedist can also perform open surgery on the knee, which allows him or her to see the injury without the aid of a television screen.
Physical TherapyDepending on the type of knee injury you have, your doctor may recommend rehabilitative physical therapy. Working with a physical therapist, you'll do specific exercises designed to take your knee joint through its range of motion to prevent stiffness and scarring as your knee heals. You may also need to do regular exercises to strengthen the muscles surrounding the knee. Physical therapy is commonly used to help a person recover after surgery.

You may be anxious for your knee to heal so you can get back to your sport and your normal life. But trying to rush your recovery after an injury or surgery can put you at risk for future injury and may further extend the healing process. Take your doctor or physical therapist's instructions seriously, and don't put your health in jeopardy by returning to your normal activities before you get the go-ahead from a health pro.

Preventing Knee InjuriesPreventing knee injuries from the start is a lot less painful and a lot less hassle than undergoing surgery. If you play sports, always wear appropriate protective equipment during practices and competitions. Kneepads and shin guards (as well as helmets and other protective gear) will help to protect you from injury. You'll also want to make sure you wear supportive shoes that are in good condition and are appropriate your sport.

When it comes to your workouts, always warm up and cool down, and remember to work up to your training program slowly. Suddenly increasing the intensity or duration of your workouts can lead to overuse injuries. Try weightlifting to strengthen your muscles and stretching and yoga to improve your flexibility because strong, flexible muscles help support and protect joints. If you play only one sport, try conditioning and training year-round - even if it's at a lower intensity than during your competitive season - to maintain coordination and balance. That way you'll be less likely to injure yourself during your competitive season.

In growing kids and teens, imbalances in muscle flexibility and strength can lead to injuries and inflammation from overuse. Regular stretching can help. After an injury or surgery has healed, it is also important to continue a regular stretching or conditioning program to prevent another injury.

The way you move can also help you prevent knee injuries. If your sport involves a lot of jumping, make sure to bend your knees when you land, which takes pressure off of the ACL. Do you have to cut laterally or pivot frequently in your sport? Use your joints to crouch and bend at the knees and hips, reducing your chance of a ligament injury.

Remember, if you experience any symptoms of knee injuries or knee pain, don't hesitate to tell your coach, parent, or doctor. Limit your activities until you can get treatment or a diagnosis.
