How long does the pain last after a knee replacement?

With an acute injury, the patient often describes that they heard a loud pop and then developed intense pain in the knee. The pain makes walking or weight-bearing very difficult. The knee joint will begin to swell within a few hours because of bleeding within the joint, making it difficult to straighten the knee.

If left untreated, the knee will feel unstable and the patient may complain of recurrent pain and swelling and giving way, especially when walking on uneven ground or climbing up or down steps.

    The knee is one of the most commonly injured parts of the body. Sports, falls, and motor-vehicle accidents account for the vast majority of knee pain and injuries to the knee.

    The different types of common knee injuries to the knee are defined by the affected anatomy of the knee and the mechanism by which it’s injured.

    Knee sprains are injuries to the ligaments that hold the knee together. There are multiple ligaments that stabilize the knee and keep it in alignment. The anterior cruciate ligament and the posterior cruciate ligament stabilize the knee in movement from front to back and cross each other in the middle of the knee joint. The medial collateral ligament and lateral collateral ligament stabilize the knee so that the bones do not slide from side to side.

    Ligament sprains are graded by the amount of stretching or tearing of the ligament fibers and how much instability it causes as follows:

      Seven Most Common Knee Injuries

      The knee joint is one of the largest and most complex joints in the body.

      It is also one of the most important joints. Connecting the thigh bone to the shinbone, it plays an important role in supporting the bodys weight, and facilitating movement allowing you to bend your knee.

      Due to the complexity of the knee joint, it is susceptible to a number of different injuries. Some of the most common knee joint injuries include tears in the ligaments, tendons, and cartilage. The kneecap itself can also be fractured or dislocated.

      Lets look at some of the most common knee injuries. See how they are caused and the treatment thats required to address them.


      The kneecap is a shield for your knee joint, and protects it from becoming injured or damaged during a fall. Because of this, the kneecap can become broken during a high impact fall or sports injury.

      Kneecap fractures are a common yet serious injury that usually requires immobilization or in some cases surgery to correct.


      Knee dislocations occur when the knee bones become out of place. This can occur after a major trauma such as a fall, car crash, or high-speed impact. It can also be caused by twisting the knee while one foot is firmly planted on the ground.

      Anterior Cruciate Ligament Injuries

      The anterior cruciate ligament is knee tissue that joins the upper and lower leg bones together and helps keep the knee stable.

      Posterior Cruciate Ligament Injuries

      Collateral Ligament Injuries

      Meniscal Tears

      Helping Your Knee To Recover After Injury

      Most people wonder if knee injuries can heal on their own. The answer is yes, but it depends on the type of injury. If you simply strain or sprain your knee, it can heal by itself if you allow it time to rest and repair.

      Major injuries such as ligament or cartilage tears may require surgery. In many cases, however, even surgery doesnt completely fix the problem and the knee doesnt return to its original healthy state. An alternative treatment is stem cell-based therapy, which regenerates the knee and its functionality at the cellular level.

      If you have arthritis or damage that caused wear and tear to the knee, you may have had a knee replacement to restore function to the joint. After surgery, some pain is normal. About 30 percent of patients experience moderate pain after a total knee replacement. However, if the pain lasts for several weeks following surgery, it may be a cause for concern.

      What Can Happen If You Dont Treat A Knee Injury Properly

      How Long Does Knee Pain Last After Knee Replacement ...

      For most people, healthy knees are an important part of a happy existence. Imagine having a knee that cannot bend, or lacks the stability to lock and support your body. Without functioning knees, living an active life is much more difficult, therefore it pays to take care of these vital joints and get appropriate treatment if you are unfortunate enough to be injured.

      Knees are like big, complicated hinges that are also subject to wear and tear, and preventative measures during some activities and sports can be helpful in protecting your knees. Taking measures to reduce the stress on knees is much easier than recuperating from an accident as some knee injuries can take a long time to heal and cause a great deal of pain, not to mention the potential long term effects of sustaining an injury.

      What Causes Knee Injuries

      More often than not, knee injuries are caused by overexerting the knee or the areas surrounding it. While doing sports, athletes could possibly bend or twist it in such a way that a muscle tears or a bone breaks. Accidents involving high amounts of force such as motor vehicle crashes can also cause knee injuries. Having certain diseases such as osteoporosis, arthritis, or joint disease can also increase ones chances of injuring their knees. Though it is impossible to completely avoid injury, here are several risk factors that could increase the chances of knee injury:

      Knee Injury Risk Factors

      • Sports – Many sports require movements that place added stress on your knees Skiing, for example, can lead to stress on the knees due to the restricted movement of your feet. Another example is basketball where players have to pivot and jump. These sudden and repetitive movements can put stress on the knees.
      • Previously injured knee – If youve already hurt your knee once, then it may not be as strong as it was before. Unfortunately, this could make it easier for you to injure your knee again.
      • Excessive weight – If you put on a lot of weight, your bones have more work to do to support that mass. For those who are very overweight, even ordinary daily activities can cause wear and tear on the knees.
      • Weak muscles – A lack of strength and flexibility in your muscles can also contribute to knee injuries. Strong muscles protect bones and joints. Aside from this, they also make you very stable and balanced, thereby decreasing the risk of falls.
      • Gender – Women are more likely to develop knee injuries simply because of how their bodies are built, for example, the way their hip bone is attached to the thigh bone and the fact that they carry greater mass on the lower body.

      Indications Of Knee Aspiration For Therapeutic Purposes Include

      • Relieving Tense Effusion When knee swelling is large or tense or pain causes discomfort, drainage of fluid helps to relieve the pressure and pain.2 Reduction in swelling and decreased tension aids in improving joint movement.
      • Drainage of Infected Fluid In a known infective condition, drainage of septic effusion can help in providing relief, improve joint movement and prevent damage to the joint.
      • Injection of Medications into the Knee Joint Knee aspiration and injection is at times performed to provide relief in joint conditions.3

      Complications Of A Swollen Knee

      How Long Does the Pain Last After Knee Replacement Surgery?

      You may develop a Baker’s cyst. This is when joint fluid leaks out into the back of the knee and causes pain and swelling. Treatment usually involves compression and applying ice packs. However, if your swelling is severe, you may need to have the fluid removed using a fine needle.

      You may lose muscle mass, especially in your thigh muscles. This is because fluid in your swollen knee can prevent your thigh muscles from working properly; over time this causes them to weaken and deteriorate.

      How To Treat A Bruised Knee

      Most bruises, also known as contusions, are mild and heal on their own. However, more severe contusions can damage muscle tissue or bone, which may take longer to heal.

      According to the American Academy of Orthopedic Surgeons, rest, ice, compression, and elevation may help reduce symptoms and aid healing.

      This article explores how bruises form, how to treat them, and how to tell if a bruise could be a sign of a more severe injury, such as a fracture.

      A bruise or contusion forms when small blood vessels under the skin break, but the skin remains intact. Blood leaks out of these broken capillaries into the surrounding soft tissues, which causes discoloration.

      There are three types of bruises:

      • subcutaneous, which occur just under the skins surface
      • intramuscular, occurring within the underlying muscle
      • bone bruises, which are an injury to the bone

      A bone bruise is typically the most painful type of bruise. Doctors can only detect these using magnetic resonance imaging, as they are not easily visible on X-rays.

      A bruise on the knee may occur because of damage to the skin, tendons, ligaments, or the bone of the knee cap. For example, a knee injury may cause a tear in the anterior cruciate ligament, in addition to bruising.

      A bruise on the knee may appear black, blue, or purple on lighter skin, or dark purple or brown on darker skin. Bruises may change color as they heal, turning yellow or green.

      A knee bruise may also trigger symptoms such as:

      Treatment For Knee Pain After A Fall

      Treatment must be specific to the pain and the injury. Your doctor might prescribe anti-inflammatory medication for torn cartilage, and rest, ice, compression and elevation for a torn hamstring. Tears of the medial collateral knee ligament require rest, however rarely surgery. Injuries to the anterior cruciate generally require surgical repair. Use rest, ice compression and elevation during the pre-surgical period. Physiotherapists at the Vail Valley Medical Center recommend that you place the pillow used for elevation under the foot, not under the knee. Placing the pillow under the knee keeps the leg in a perpetually flexed position, which might postpone the ability to extend your leg.

      How Long Does It Take To Recover From A Soft Tissue Injury

      Many people are surprised at how long a soft tissue injury takes to heal and wonder why theyre not fully recovered and back to normal two or three weeks later.

      Unfortunately, this is normal as the time it takes for your body to complete tissue healing is actually much longer.

      So what actually happens when you sprain your ankle, damage your knee or strain some muscle fibres?

      There are four main stages that your body goes through, although in reality these arent distinct and they all overlap:

      Phase 1: Bleeding

      Just like a cut to your skin causes external bleeding, a bruise is a sign of bleeding from your internal soft tissues. Muscles have a very good blood supply and therefore bleed more and for a longer time, often producing a large bruise. Ligaments dont have a great blood supply so will bleed less.

      Its important to rest during this phase to allow time for the bleeding to stop .

      Phase 2: Inflammation

      Inflammation starts within the first hour or two after injury, peaks within 1-3 days but lasts at least a couple of weeks. This phase is when you will experience swelling and some heat around your injury.

      This is entirely normal and a natural part of your bodys tissue healing process. It needs to occur and there is nothing you can do to prevent it. Follow these treatment principles to improve your recovery time P.O.L.I.C.E:

      Ice this will largely help with pain relief very early on. Try applying an ice pack for up to 15 minutes, 2-3 times per day

      Healing A Swollen Knee And Leg

      How Long Does Pain Last After a Total Knee Replacement?

      Q1. I fell on the sidewalk about a month ago and skinned and bruised my knee. I went home, iced my knee, and put Bactine and Neosporin on it. I had a lot of pain in my knee. I noticed there is swelling around my kneecap. It looks like fluid inside. What should I do?

      Angela, New Jersey

      Following trauma to any part of our bodies, it is very natural to bleed. When the bleeding occurs into the skin, we develop what is referred to as a hematoma, a collection of blood in the soft tissue. Hematomas will usually heal over time; all that is necessary to help with the healing is application of ice at first, followed by heat. Bleeding can occur into other parts of our body as well.

      I would strongly recommend you visit your physician so that a determination can be made as to whether the fluid is in the bursa which is less serious or in the joint, which would be of greater concern. Once the diagnosis is made, appropriate treatment can be initiated. Warning signs of fluid in your joint would include a decrease in the knee’s range of motion, as well as fever or increased pain.

      Q2. Sometimes my knee is swollen and painful. What could be the cause of my sore knee?

      There are lots of reasons you may have sore, achy, and stiff knees. If your knee is swollen and painful, or if it ever gets locked and immobile, you need to see a doctor who can make a diagnosis.

      Q3. What could cause knee pain and a swollen leg, swollen ankles, a swollen calf, or swollen joints?

      Conditions That May Cause Knee Problems

      Problems not directly related to an injury or overuse may occur in or around the knee.

      • Osteoarthritis may cause knee pain that is worse in the morning and improves during the day. It often develops at the site of a previous injury. Other types of arthritis, such as rheumatoid arthritis, gout, and lupus, also can cause knee pain, swelling, and stiffness.
      • Osgood-Schlatter disease causes pain, swelling, and tenderness in the front of the knee below the kneecap. It is especially common in boys ages 11 to 15.
      • A popliteal cyst causes swelling in the back of the knee.
      • Infection in the skin , joint , bone , or bursa can cause pain and decreased knee movement.
      • A problem elsewhere in the body, such as a pinched nerve or a problem in the hip, can sometimes cause knee pain.
      • Osteochondritis dissecans causes pain and decreased movement when a piece of bone or cartilage or both inside the knee joint loses blood supply and dies.

      Can Knee Injuries Be Prevented

      Unfortunately, no matter how much we try to be careful, there is always the risk of an innocuous incident or unlucky accident causing a knee injury.

      However, we can take precautions to decrease the risk of injury or prevent the wear and tear of the protective layers around our knees. Here are some practical tips to lower the chances of hurting your knee:

    • Wear protective gearIf you regularly play sports or work in an industry that causes a lot of stress on your knees, make sure to wear protective gear. Dont forget to wear proper shoes, preferably ones that absorb shock which put less stress on your knees.
    • Strengthen your muscles with exerciseThere are many types of exercises which help you prevent knee injury. You can do squats, lunges, and other stretching exercises. Its especially important to do this before and after a workout or other extreme physical activities.
    • Understand your limits and take a restUnderstanding your limits doesnt only apply to people who have been injured. If you play sports or go to the gym frequently, make sure you know your limits and give yourself time to rest. Your muscle repairs itself during that time and fatigue can also cause you to be less careful, which can lead to accidents.
    • Improve your posture and exercise techniqueSometimes we may be doing our exercises the wrong way. The incorrect posture while doing squats or lunges can cause additional stress on our knees. Ask your trainer or coach for help to improve your posture or technique.

      Strength Balance And Pain Intensity

      Pain has a number of sequelae, including an increased likelihood of falling due to musculoskeletal inhibition also known as arthrogenic or reflex inhibition .22;In some cases, the body may react to protect itself from further movement-related harm by interfering with the ability to achieve maximum voluntary muscle contraction after physical injury has occurred. While RI functions as a protective action, it also poses a threat during circumstances in which safe and necessary movements are required.

      Although the link between chronic pain and the occurrence of falls remains poorly understood, clinical observation suggests that the presence of pain, especially long-term, may undermine muscular function and joint integrity. In the same regard, chronic pain may interfere with dynamic balance, mobility, and cognition, thereby accelerating functional decline.23

      The intensity of pain is important in studies demonstrating a threshold whereby RI is triggered. There may even be various degrees of inhibition controlled by central and peripheral nervous systems according to some research.24;Studies have confirmed that strength levels in patients with knee osteoarthritis represented a critical determinant of dynamic balance, for example.24
