Why Does My Shin Bone Hurt After Knee Replacement

Persistent Pain After Knee Replacement Surgery

Your shin bone is called your tibia. The primary reason we believe this bone hurts is because of the new loading forces being placed on the bone after your surgery.

Before surgery, your knee likely wasnt straight.

Now, after surgery, you may not have a full range of motion yet, but the alignment of the implant is perfectly straight.

This new alignment is placing new stress and strain on the shin bone.

Your body will adapt to these new forces but it will take months and sometimes as long as a year.

How To Relieve Sharp Stabbing Pain In Front Of The Knee

  • Improve quadriceps flexibility. The quadriceps are a muscle group in the front of the thigh that straightens the knee. Quadriceps means in Latin “four heads,” but the one that most often causes trouble is a 2-joint muscle that also flexes the hip. Watch this video to learn how to stretch your quadriceps and hip flexors.
  • Use your glute muscles more, so that the quadricep muscles don’t get overworked. One easy way to do this is to keep your weight more on your heels than on your toes when doing things like squatting and going up and down stairs.
  • The Patient Problems After Knee Replacement Surgery Are Many At Caring Medical We Can Address Many Of These Problems We Cannot Address All Especially When The Problem Of Knee Replacement Is Caused By Hardware Failure And Hardware Placement Failure

    • PROBLEM: The knee replacement hardware is wearing out and loosening or it was not placed in the knee correctly and stress is causing the device problems. This problem will need surgical consultation and possibly revision surgery.
    • PROBLEM: Infection. This is during the initial recovery period. On prosthetic devices, bacteria can form and colonize. This problem will need a consultation with the surgical group and possibly emergency medicine.
    • PROBLEM: The implant or the surgery caused fractures in the thigh or shin bone. This problem will need a consultation with the surgical group and possibly emergency medicine.
    • PROBLEM: Knee prosthesis instability and loss of range of motion , this can also lead to considerable pain.

    Here Are A Few Things You Can Expect After Knee Replacement Surgery:

    • Rest and Ice: The knee will be swollen and tender, which is why you need to follow doctor suggestions for keeping the leg elevated and icing the joint.
    • Medications: Not only does medication help with pain management, but it is also vital to reduce inflammation. Sometimes antibiotics are needed for preventing infection.
    • Follow Up: You will have follow-up appointments to talk to your sports medicine doctor about recovery. Surgical staples or stitches will be removed during the office visit. Reach out to your doctor if you notice unusual symptoms, such as redness, fever, incision drainage, or increased pain.
    • Home Modifications: You might need certain modifications to help you navigate your home. Since the knee needs to heal, you must use crutches. Some patients transition to a cane or walker as the recovery progresses. Consider using other modifications, such as handrails, a shower bench, a reaching stick, and removing loose cords and rugs that could cause a fall.

    What Does Knee Pain Feel Like

    Total knee replacement

    Knee pain can take many different forms. You might experience burning knee pain at night as an uncomfortable, steady warmth in the joint. You may also have throbbing knee pain at night, no matter what position you lie in.

    Some people have pain that is sharp when they switch positions after being still. Other forms are not pain at all but can consist of tenderness or swelling inside the joint.

    Problem: Difficulty And Pain In Kneeling

    Most people had difficulty kneeling because of pain or discomfort in the replaced knee. Many patients described how this limitation affected their daily lives, including housework, gardening, religious practices, leisure activities, and getting up after a fall. Patients often adapted to these limitations by finding alternatives to kneeling, assistance from others, or home adaptations. Many patients had accepted that they could not kneel, however some still expressed frustration. Few patients had consulted with healthcare professionals about kneeling difficulties, and unmet needs included the provision of information about kneeling and post-operative physiotherapy.

    Painful Knee After Total Knee Arthroplasty What Can Be Done Find A Diagnosis

    Diagnosis of what is causing knee pain after a knee replacement is hard to find. The first thing to look for is some type of hardware failure or pain caused by the surgery itself. You knee a knee surgeon to help with that.

    In December 2020, doctors in Germany offered the suggestion that you need a surgical specialist in fixing a bad knee replacement to start the process of understanding why the knee replacement failed.

    • About one-third of all patients after total knee arthroplasty experience persistent or recurring pain and/or dissatisfaction. Clinically, the symptoms are very complex and vary greatly from individual to individual. Diagnostic clarification is difficult and should be carried out by an orthopedic surgeon specializing in knee arthroplasty revisions. Only if the cause of the complaints are identified is there a chance of improvement, regardless of whether conservative or surgical treatment is used.

    Researchers at the Department of Surgery, Southern Illinois University School of Medicine offered this assessment in the medical information publication Instructional Course Lectures to guide doctors trying to help patients with pain after knee replacement.

    Establishing a precise diagnosis of where the pain is coming from can be challenging.

    According to the research: This is what doctors need to look for in trying to find the source of knee pain after knee replacement:

    Pain At The Front Of The Knee

    • Excessive stress on the patella tendon at the front of the knee, just below the patella, manifests itself by a burning sensation at the front of the knee .
    • A severe stabbing pain and swelling at the front of the knee may be due to a partially dislocated patella. The patella normally slides in a groove at the front of the femur, but can slip out due to a sudden twist or impact.
    • Chondromalacia patellae is a condition due to the cartilage on the under surface of the patella softening and deteriorating. The symptoms are a grating feeling at the junction of the patella and femur. Sometimes an unstable flap of surface cartilage may cause this pain, and may be curable with simple keyhole surgery and a chondroplasty.
    • Repetitive knee movements can result in an accumulation of fluid in the bursae resulting in pain and a swelling at the front of the knee .

    Patients May Still Be Undergoing Knee Replacement For Degenerative Lumbar Spine And Hip Osteoarthritis

    Pain After Total Knee Replacement Surgery

    Patients may still be undergoing knee arthroplasty for degenerative lumbar spine and hip osteoarthritis. . . We suggest heightened awareness at pre-and post-operative assessment and thorough history and examination with the use of diagnostic injections to identify the cause of pain if there is doubt.

    In other words, patients received a knee replacement when the cause of pain came from the hip and spine.

    In the journal Modern Rheumatology, Japanese doctors wrote:

    We suggest that rheumatologists be aware of hip disease masquerading as knee pain or low back pain.

    In the case of chronic joint pain, a thorough examination is imperative in identifying the correct diagnosis. That sounds like common sense, but the sad truth is that the source of pain is often missed because of misinterpretation of MRI and other imaging scans. Please see our article on MRI accuracy.

    What About Exercise Following A Knee Replacement

    Exercise and sport are recommended after knee replacement, apart from contact sports, which may weaken the cement and lead to loosening of the joint components. Recreational sports including golf, tennis and skiing will gradually become possible depending on how fit and sporty you were before the operation. Cycling is a very good way of building up strength and mobility after knee surgery.

    Exercising the main muscle groups around your knee is very important both before and after having a knee replacement. You can download a selection of exercises that are designed to stretch, strengthen and stabilise the structures that support your knee. Try to perform these exercises regularly, for instance for 10 minutes six to eight times a day. However, its important to find a balance between rest and exercise so you dont overwork your knee. Its a good idea to get advice from your doctor or physiotherapist about specific exercises before you begin.

    How Can We Help These Problems The Often Overlooked And Ignored Cause Of Pain After Knee Replacement The Knee Ligaments

    When a knee replacement is performed, the joint itself has to be stretched out so the surgeons can cut out bone and put it in the prosthesis. When the joint is stretched out, the knee ligaments and tendons that survive the operation will cause pain as they heal from the surgical damage. Sometimes the ligaments and tendons heal well. Sometimes they do not heal as well.

    In this video, Ross Hauser, MD explains the problems of post-knee replacement joint instability and how Prolotherapy injections can repair damaged and weakened ligaments and that will tighten the knee. This treatment does not address the problems of hardware malalignment that our patient Jeannette described in the video above.

    Summary of this video:

    The patient in this video came into our office for low back pain. I did a straight leg raise test, on this patient to help determine if his back pain was coming from a herniated disc.

    • During the test I noticed a clicking sound coming from his knee. The patient had a knee replacement.

    It is very common for us to see patients after knee replacement who have these clicking sounds coming from knee instability. This is not an instability from hardware failure. The hardware may be perfectly placed in the knee. It is instability from the outer knee where the surviving ligaments are. I believe that this is why up to one-third of patients continue to have pain after knee replacement.

    What Is Revision Total Knee Replacement

    What is Total Knee Replacement (TKR) ?? â All The Pros ...

    Revision total knee replacement is the replacement of a failed total knee prosthesis with a new prosthesis. In simple terms, it is the replacement of a knee replacement .

    Knee revision surgery is a complex procedure that requires extensive preoperative planning, specialized implants and tools, prolonged operating times, and mastery of difficult surgical techniques to achieve a good result.

    Technical Details Of Total Knee Replacement

    Total knee replacement surgery begins by performing a sterile preparation of the skin over the knee to prevent infection. This is followed by inflation of a tourniquet to prevent blood loss during the operation.

    Next, a well-positioned skin incisiontypically 6-7 in length though this varies with the patients size and the complexity of the knee problemis made down the front of the knee and the knee joint is inspected.

    Next, specialized alignment rods and cutting jigs are used to remove enough bone from the end of the femur , the top of the tibia , and the underside of the patella to allow placement of the joint replacement implants. Proper sizing and alignment of the implants, as well as balancing of the knee ligaments, all are critical for normal post-operative function and good pain relief. Again, these steps are complex and considerable experience in total knee replacement is required in order to make sure they are done reliably, case after case. Provisional implant components are placed without bone cement to make sure they fit well against the bones and are well aligned. At this time, good functionincluding full flexion , extension , and ligament balanceis verified.

    Finally, the bone is cleaned using saline solution and the joint replacement components are cemented into place using polymethylmethacrylate bone cement. The surgical incision is closed using stitches and staples.

    Lack Of Evidence About The Effectiveness Of Prediction And Management Strategies For Chronic Postsurgical Pain After Total Knee Replacement

    The same doctors also wrote in the British Medical Journal that the problem of post-surgical pain in knee replacement patients had reached a point of significance and that researchers should prioritize their studies to help people with pain. They wrote:

    • Our highlights a lack of evidence about the effectiveness of prediction and management strategies for chronic postsurgical pain after total knee replacement. As a large number of people are affected by chronic pain after total knee replacement, development of an evidence base about care for these patients should be a research priority. We are going to return to this study below.

    There is a significant problem. The main part of this problem is identifying what is causing people to have pain after knee replacement.

    Mayo Clinic Q And A: Pain After Knee Replacement Surgery

    DEAR MAYO CLINIC: It has been months since I had knee replacement surgery, but my knee is still hurting. Can anything be done at this point, or does the surgery just not eliminate pain in some patients?

    ANSWER: Although its uncommon, a small percentage of patients continue to have chronic knee pain after knee replacement surgery. But when that happens, you dont have to just put up with the pain. Have your situation evaluated. Several additional treatment options may ease chronic knee pain after knee replacement.

    Knee replacement surgery, also known as knee arthroplasty, is one of the most common orthopedic surgeries performed today. It is most often used to repair joint damage caused by osteoarthritis or rheumatoid arthritis that causes severe knee pain and makes it hard to perform daily activities.

    During knee replacement, a surgeoncuts away the damaged bone and cartilage from your thighbone, shinbone andkneecap, and replaces it with an artificial joint. For most people, kneereplacement significantly improves mobility and relieves knee pain. But in somepatients, the pain persists after surgery.

    Your first step in dealing withongoing knee pain in this situation is to make an appointment to see thesurgeon who performed your knee replacement. He or she can evaluate your kneeand check for possible complications from the surgery, such as an infection ora problem with the artificial joint.

    Patellar Tendinitis / Tendinopathy

    Shin Pain After Knee Replacement

    Patellar tendinitis means inflammation of the tendon below the kneecap. Tendinopathy means an abnormal condition of the tendon in which there is no inflammation. Both of these problems can still hurt, and the pain is usually felt on the front of the knee just below the kneecap.

    This type of pain is caused from too much load on the quadriceps muscles, for example when squatting or going up and down stairs.

    Flexibility of the quadriceps muscles can play a role in this type of pain, but more often it comes from the muscle overworking because the glute muscles aren’t doing their fair share.

    What about those patellar tendon straps? Do they work?

    Patellar tendon straps can help take the edge off the pain if you have patellar tendonitis. They relieve stretch on the attachment point of the patellar tendon below the knee, and thus they help temporarily, but they don’t fix the main problem. If the quadriceps muscles are still stiff, the pain will eventually come back. Keep reading to learn how to relieve pain on the front of the knee.

    What Causes Knee Pain At Night

    Our knees are complex joints responsible for bearing the weight of our bodies as it travels to our feet. They literally help us move through the world smoothly, connecting four bonesthe femur, the tibia, the fibula, and the patellaand two major muscles groups .

    Connecting and stabilizing these bones and muscles are ligaments and tendons, including:

    • The anterior cruciate ligament : Located on the front of the knee, the ACL prevents the femur from moving backwards onto the tibia
    • The posterior cruciate ligament : The PCL keeps the femur nestled back where it belongs
    • Medial ligaments: Stabilize the inside of the knee
    • Lateral ligaments: Stabilizs the outside of the knee

    In addition to this, articular cartilage lines the patella to smooth movement, as does the meniscus tissue that allows the femur and tibia to glide together. Bursa are fluid-filled sacs inside the joint. They further cushion movement, preventing painful bone against bone rubbing.

    Any part of this structure can develop painful conditions or suffer from issues that could cause knee pain at night. In general, the five main causes of knee pain at night are:

  • Knee replacement pain at night
  • Arthritis
  • Overuse
