What is a knee fracture?A knee fracture is called a patellar fracture. A patellar fracture is a break in the kneecap (patella). The kneecap is susceptible to fracture if you fall directly on the knee or sustain some other direct trauma to the patella. Show
Knee fractures are very serious injuries and can make walking and everyday activities extremely difficult. Causes of a knee fractureKnee fractures (patellar fractures) are typically caused by direct falls to the knee or sharp blows to the knee. Car accidents are another common cause of knee fractures. In rare cases, the knee can be fractured due to a sudden contraction of a quadricep where the muscles can pull from the patella. Risk factors for a knee fracture
Symptoms of a knee fractureAn immediate sign of a knee fracture is a misshapen limb or joint that could be accompanied by a visible bone outside the skin. Other signs of a knee fracture include:
Diagnosis of a knee fractureKnee fractures are diagnosed in a physical exam and using an x-ray. In a more severe fracture, a CT scan or MRI may be able to give more insight into the extent of the injury. If you think you have fractured your knee, please visit Mercy Health ER right away. Treatments for a knee fractureNonsurgical treatments for a knee fracture include:
Surgery is reserved for complicated cases where the break is resistant to healing or when the bones are displaced. If the bones are not close together, they will likely not heal properly. The goal of surgery is to repair the break by using screws, metal pins or plates. Your physician will work with you to determine the appropriate time for surgery. If the fracture is open, it is important to do it quickly in order to avoid infection. Recovery from a knee fractureRecovering from knee fractures is a slow process. During recovery, the knee will have to stay immobilized while in a brace. You will work with your orthopedic physician to determine when you can gradually put weight on the leg or knee. With treatment, a knee fracture will take six to eight weeks to heal.

What to expect
Advice for a new injury Cold packs: A cold pack (ice pack or frozen peas wrapped in a damp towel) can provide short term pain relief. Apply this to the sore area for up to 15 minutes, every few hours ensuring the ice is never in direct contact with the skin. Rest and Elevation: Try to rest the knee for the first 24-72 hours to allow the early stage of healing to begin. Raise your knee above the level of your hips to reduce swelling. You can use pillows or a stool to keep your foot up Early movement and exercise: Early movement of the ankle and foot is important to promote circulation and reduce the risk of developing a DVT (blood clot). Follow the exercises below within the limits of your pain. These exercises will help the healing process. Early weight bearing (putting weight through your injured leg) helps increase the speed of healing. Try to walk as normally as possible as this will help with your recovery. Fitting the cricket pad splint Place the cricket pad splint on the leg so that your patella (knee cap) is in the middle of the hole in the splint, as shown. Exercises Initial exercises to do 3 times a day 1. Point your foot up and down. Repeat 10 times. 2. With the leg straight and supported, gently tense your thigh muscle and try to straighten your knee further. Hold for 10 seconds and repeat 7-10 times. Can knee fracture heal on their own?If it is a stable fracture, your bone can be expected to heal without surgery. Surgery: If your bone pieces are displaced, they will need to be put back together in surgery.
When can I walk after knee fracture?For six to eight weeks or longer, you will not be able to put any weight on your leg until the bone is completely healed. Most people use crutches during this period. A knee brace may be recommended. Whether or not you have surgery, rehabilitation plays an important role in getting you back to your daily activities.
Can a knee fracture heal in 4 weeks?Healing: The fracture will take 6 weeks to heal. Some pain and swelling may be on going for 3-6 months.
