Helping Patients To Make Informed Decisions

Increase Knee Bend (Minimize Pain) After Knee Replacement/Surgery Using TENS

We’re funding research to improve patient experience before, during and after knee replacement surgery. This includes a project based at the University of Sheffield which aims to help patients make informed decisions about their surgery. The research team will use the UK National Joint Registry dataset to develop and validate a personalised, web-based decision aid to help patients considering knee joint replacement to make informed choices about their treatment.

Knee Replacement Range Of Motion Timeline: Where You Should Be After Surgery

Not only do people have different ROM potential to begin with, people also heal at different rates. With that in mind, here are the flexion goals our team of medical advisors look for in their total knee replacement patients.

  • Stage 1 65-90° flexion. This amount of flexion allows for walking without assistance, standing, and some stair climbing . Before you leave the hospital, your doctor will be looking for flexion as close to the 90° as possible.
  • Stage 2 115° flexion. At this point, you should have made noticeable improvements from your early recovery days. This means moving around normally, bending to the ground, sitting down, and even tying shoelaces!
  • Stage 3 A goal to hit 115°or greater should be the aim. The timeframe for this varies, but should be consistently work towards. A flexion of 125° is great and 135° is excellent .

Throughout each stage, its important that you keep working your surgical knee and artificial knee prosthesis. The first 3 months of your recovery are critical for working out your new knee to gain back flexibility, bending, extension, and movement. If you stay idle, inconsistent or not fully committed to gaining back range of motion, your knee may become stiff. If your knee becomes stiff, you risk the need for revision surgery and a joint that will cause lifelong issues.

Problems Of Stiffness After Knee Replacement Surgery

A total knee replacement, also called knee arthroplasty, is one of the most common types of joint replacement surgeries. It involves removing the damaged portion of the knee joint and replacing it with prosthetic materials.

Knee replacement is highly successful for relieving knee pain and restoring joint function, but some patients experience knee stiffness following the procedure. This stiffness causes a limited range of motion in the knee, and it can be accompanied by pain.

Lets talk about some of the main factors that can cause stiffness after knee replacement surgery, and where you can go in North Dakota for expert orthopedic care of your knee and other joints.

Severe Cases Of Knee Pain Or Injury

In some cases, a knee injury can be a serious injury and are so severe that they require surgery to repair. Some of the most common surgical procedures include:

ACL reconstruction: This surgery is performed to repair a torn ACL. The surgeon will remove the damaged ligament and replace it with a healthy autograft or allograft.

Meniscus surgery: This surgery is performed to repair a damaged or torn meniscus. The surgeon will remove the damaged tissue and either sew the remaining tissue back together or replace it with an artificial disc.

Reasons For The Procedure

2013: Knee Surgery at 23: 7 Weeks Post

Knee replacement surgery is a treatment for pain and disability in theknee. The most common condition that results in the need for kneereplacement surgery is osteoarthritis.

Osteoarthritis is characterized by the breakdown of joint cartilage.Damage to the cartilage and bones limits movement and may cause pain.People with severe degenerative joint disease may be unable to donormal activities that involve bending at the knee, such as walking orclimbing stairs, because they are painful. The knee may swell or”give-way” because the joint is not stable.

Other forms of arthritis, such as rheumatoid arthritis and arthritis thatresults from a knee injury, may also lead to degeneration of the kneejoint. In addition, fractures, torn cartilage, and/or torn ligaments maylead to irreversible damage to the knee joint.

If medical treatments are not satisfactory, knee replacement surgery may bean effective treatment. Some medical treatments for degenerative jointdisease may include, but are not limited to, the following:

  • Anti-inflammatory medications

  • Cortisone injections into the knee joint

  • Viscosupplementation injections

There may be other reasons for your doctor to recommend a knee replacementsurgery.

  • Locked knee condition This happens by a mechanical impairment in extending your knee like a bucket handle tear of the meniscus, or loose osteochondral fragments.
  • Patellofemoral syndrome This is also called runners knee syndrome because its a condition that grows with the overuse of the knee joint or injuring the knee. This condition is very popular among athletes but even if youre not one, that doesnt mean that youre out of the woods.
  • Patellar Tendonitis This too is a common athlete injury that causes inflammation of the tendon that attaches your kneecap to your shinbone. Your pain might differ from mild to severe when trying to bend your knee. A 2005 study revealed that roughly 40 to 50% of skilled volleyball players have gone through this injury.
  • Osteoarthritis This disorder mainly happens as you age. Its a specific tear on your joints as the cartilage that protects your joints start wearing out and making your bones rub against each other eventually causing inflammation in the joints. So, if you try to get past a 90-degree bend, you will feel it. This is not just limited to your knees, but can also affect your hips, wrists, ankles, and fingers.
  • Since most of the above-mentioned conditions are triggered by knee injuries, it is important to know at what point can a knee injury be risky.

    As our bodies are healing from surgery, our tissues are undergoing many changes. YOU are your bodys best healer! Early mobility has not only been deemed appropriate after surgery but also necessary in order to facilitate a healthy healing response. An article by Kaye et al discusses the positive outcomes related to early mobility after surgery, some of which include decreased hospital length of stay, improved patient satisfaction, and decreased postoperative complications! Later on, in the middle and late tissue healing phases specifically, we want to gently apply forces to the tissues inside of the knee to increase the range of motion. This will assist in tissue remodeling and the long-term success of tissue healing.

    Our Patient Jeannette Had Issues With Spinal Stenosis And Problems Post

    • Jeannette starts discussing the knee replacement complications at 3:50 in the video. Jeannette is 81 years old.

    Jeannette describes a foot-tingling problem. She cannot sit down and relax at the end of the day, it is uncomfortable for her to put her feet up or down because it is tingling. She had a nerve conduction study that shows an injury to her peroneal nerve. The peroneal nerve branches out from the sciatic nerve. As it provides sensation to the front and sides of the legs and to the top of the feet, damage to this nerve would result in burning and tingling or numbness sensation in these areas. Further damage to this nerve would also cause loss of control in the muscles in the leg that help you point your toes upward. This can lead to walking problems and possibly foot drop, the inability to lift the front of the foot or ankle. Knee and hip replacement are leading culprits in the cause of peroneal nerve injury.

    In Jeannettes case, she had two knee replacement surgeries in that knee. After the first knee replacement surgery, the implant started to protrude away from the limb. The knee replacement became loose. The second surgery to fix the first one occurred in 2015.

    It was determined after examination that Jeannettes knee ligaments were loose. Her knee was hypermobile and unstable. This was causing pressure on her peroneal nerve. Knee ligament damage and weakness is also a complication of knee replacement surgery and is discussed further below.

    What Should I Expect During Weeks 6 Through 12

    When Repair May Be Better Than Removal of a Torn Meniscus

    This period after joint replacement is a time of continued improvement. You will probably notice an increase in energy, a desire to do more activities, and a noticeable improvement in your new joint. Please keep in mind that every patient is different and will improve at different pace. If you are not happy with the pace of your recovery, please contact your surgeons office to discuss your concerns.


    After your six-week follow-up visit, you will likely start using a cane to walk and move about. Use the cane until you return for your 12-week follow-up visit. Walk with the cane as much as you want as long as you are comfortable.

    Back to work

    Many patients return to work after the six-week follow-up visit. Tips to remember for returning to work include:

    • Avoid heavy lifting after you return to work.
    • Avoid standing or sitting for long periods of time.
    • Avoid activities such as frequently climbing stairs or climbing ladders.
    • Avoid kneeling, stooping, bending forward or any position that puts the new joint under extreme strain.
    • Expect a period of adjustment. Most people return to work with few problems. However, you may find the first several days very tiring. Give yourself time to adjust to work again and gradually this should improve.

    Reduced Need For Surgery

    One 2014 study suggests that the zero-gravity nature of inversion can reduce compression. The authors of the study also noted that inversion may potentially prevent disability from back problems. This could also reduce the need for spinal surgery.

    A 2012 study from Disability and Rehabilitation found that people with lumbar disease reduced their need for surgery six weeks after using inversion therapy.

    Despite these findings, its important to note that back problems are complex. Inversion therapy is not a guarantee against surgery, nor should it be an alternative treatment for back pain. Talk to your doctor before trying inversion therapy as a treatment or form of exercise.

    The inversion exercises a person can do depends on the equipment available.

    Types Of Arthritis That Affect The Knee

    Inflammatory arthritis

    This broad category includes a wide variety of diagnoses including rheumatoid arthritis, lupus, gout and many others. It is important that patients with these conditions be followed by a qualified rheumatologist as there are a number of exciting new treatments that may decrease the symptoms and perhaps even slow the progression of knee joint damage.

    Patients with inflammatory arthritis of the knee usually have joint damage in all three compartments and therefore are not good candidates for partial knee replacement. However, inflammatory arthritis patients who decide to have total knee replacement have an extremely high likelihood of success. These patients often experience total, or near-total, pain relief following a well-performed joint replacement.


    Osteoarthritis is also called OA or degenerative joint disease. OA patients represent the large majority of arthritis sufferers. OA may affect multiple joints or it may be localized to the involved knee. Activity limitations due to pain are the hallmarks of this disease.

    OA patients who have symptoms limited to one compartment of the knee sometimes are good candidates for minimally-invasive partial knee replacement .

    The 3 Main Reasons Why Your Knee Can’t Bend After Surgery #KneeClub

    After a total knee replacement surgery, you will most surely witness some discomfort during the recovering process, especially since you cant directly go back to bending your knee completely.

    You will notice that your knee can automatically position at a 90-degree angle. To practice bending further, you can try sitting upright on a chair and slowly move your leg forwards till it stays stretched with the toes on the floor.

    Then you can bring your leg backward unto the foot of the chair. This motion applies only a small amount of pressure to feel the least amount of pain.

    I Thought I Would Be Able To Kneel After Knee Replacement I Cant An Expectation Of The Total Knee Replacement To Improve Patients Ability To Kneel Was Associated With Lower Odds Of Satisfaction

    Lets remind ourselves here that many people have very successful knee replacement surgeries and they can function better afterward. These are not the patients we see. We see patients who had an over-expectation of what their knee replacement could do for them and then they found out, the knee replacement could not help them do all the things they thought it could.

    Led by researchers at the University of Toronto and the University of Calgary, a 2021 study published in the journal Arthritis & Rheumatology assessed the relationship between patients expectations for total knee replacement and satisfaction with surgical outcomes.

    What the researchers did was look at patients who received total knee replacement surgeries and then they gave questionnaires that measured depression scale, body mass index , comorbidities , and prior joint replacement), at 1-year post-total knee replacement to assess overall satisfaction with total knee replacement results.

    The researchers then divided up responses to see what the patients considered important factors in their satisfaction or dissatisfaction with the knee replacement.

    Here is what 1,266 patients who had a knee replacement had to say:

    • 74.7% of patients were very satisfied,
    • 17.1% were somewhat satisfied,
    • and 8.2% were dissatisfied.

    An expectation of the total knee replacement to improve patients ability to kneel was associated with lower odds of satisfaction
