Is it common when having a total knee replacement the upper part is not cemented in the femur but the part in the tibia was cemented.

Is it common when having a total knee replacement the upper part is not cemented in the femur but the part in the tibia was cemented.

Knee replacements: Total knee replacements have traditionally been cemented on the femoral and tibial sides, but non-cemented versions are becoming more attractive for surgeons. Solid fixation to bone is paramount with non-cemented components. Cement is necessary if this is not achieved. In your case, the femoral component was likely well fixed, but tibial component likely required cement to ensure good fixation ...Read more

Could the entire femur bone be replaced along with a total knee replacement?

Could the entire femur bone be replaced along with a total knee replacement?

Yes: Replacing the entire femur can be done, but it is rarely needed. Only patients with extensive cancer or many failed operations on the femur, might need it replaced completely. ...Read more

Could the entire femur bone be replaced along with a total knee replacement?

Could the entire femur bone be replaced along with a total knee replacement?

Femur bone: In a knee replacement only the most distal aspect of the femur is replaced along with the proximal tibia and underlying portion of the patella. In extreme situations such as bone/soft tissue cancer that involves the femur shaft or infection can the entire femur bone be replaced. Even then the hip region may be salvaged. Choices are metal implants or cadaveric bone. Evenutally we will have scaffol. ...Read more

I Have bone on bone knee arthritis. I feel September 18th 4 days prior to total knee replacement. I fractured my femur neck. How longbefore I'm walkin?

I Have bone on bone knee arthritis. I feel September 18th 4 days prior to total knee replacement. I fractured my femur neck. How longbefore I'm walkin?

Varies: It varies based upon the type of femoral neck fracture you had and type of surgery used to fix it. For example, in a displaced femoral neck fracture we often do a cemented hemi arthriplastyband you can begin walking on it that day. In a fracture fixed with screws, weight bearing is based in part on the quality of bone purchase noted intra operatively. Discuss with your surgeon. ...Read more

Advanced articular cartilage loss in medial compartment of tibio-femoral and patella-femoral joints. Would partial (unicondylar) knee replacement work?

Advanced articular cartilage loss in medial compartment of tibio-femoral and patella-femoral joints. Would partial (unicondylar) knee replacement work?

Maybe: This decision is best made by your own orthopedist who has direct access to your x rays. A second opinion never hurts. In someone so young, if you can get away with something short of a total joint replacement, it is always preferable to do so. ...Read more

I m 27 yr. I have a distal femor knee replacement surgery & I m 17 weeks pregnat too is the srgery affect my baby if they give general aneastesia?

Yes: If you are asking if general anesthesia could potentially have adverse affects on your pregnancy and your unborn baby, then the answer is yes. So in general pregnant women should avoid surgery unless it absolutely must be done. ...Read more

Is it common after a partial knee replacement to experienc a clicking sound when you bend your leg?

Is it common after a partial knee replacement to experienc a clicking sound when you bend your leg?

No but its okay: Painless clicks in the knee are not a concern.
Painful clicks are investigated.
Clicking early after partial knee replacement can occur in some patients but usually goes away over a few weeks or months.
It is usually occurring from the metal femoral component tapping against the polyethylene plastic bearing when you go from the swing phase of gait to heel strike. Heard mostly by the patient. ...Read more

Having a knee/partial femur replacement to remove cancer in 20 days, what can I do to prepare?

Having a knee/partial femur replacement to remove cancer in 20 days, what can I do to prepare?

Get informed well: Removal of your knee area bones means having to adjust to an artificial knee joint. For this you should plan/ learn how to get rehabilitated after the surgery is over you will need strong muscles to get you thru this journey and be able to start walking normally again. You should exercise/walk to strengthen your muscles around the knee. ..The quads and hamstring (back thigh) muscles. Good luck! ...Read more

My knee is stiff it will not bend or straighten out form knee replacement I wear brace but it won't help I must have revision or arthroscopy also pt?

See a Doc: If your knee is stiff and will not bend normally after a total knee replacement, you should see the doctor who operated on you. Sometimes it may be necessary to do something called a manipulation under anesthesia to break up scar tissue that may have formed to improve the range of motion. A brace will not help you get the range of motion back. ...Read more

What are the chances of going from a partial to a full knee replacement?

What are the chances of going from a partial to a full knee replacement?

Need a good install: If your a good candidate, then the most important factor in a long term result of a partial knee replacement is the installation accuracy. Poor result due to surgeon installation difficulty has lead most surgeons to perform total knees on everyone with arthritis. Using the makoplasty robotic system in over 500 patients I have found consistantly precise installation every time. 15-25 years in most. ...Read more

What all happens during a partial knee replacement?

What all happens during a partial knee replacement?

Surfaces restored: When one side of your knee joints cartilage wears down, you can resurface the end of the bone with a femoral implant made of cobalt chrome and a tibial component made of titanium and polyethylene. These implants are secured to the bone with a special cement. Precision installation is the key to long term success. Robotics has made this a reproducibly excellent joint retoring procedure. ...Read more

What should I expect after a partial knee replacement?

What should I expect after a partial knee replacement?

Relief from pain: A partial knee replacement involves a resurfacing of one of three parts of the knee (medial, lateral, or patella-femoral compartments). There may be some lateral knee numbness after surgery. Recovery is quicker than a total knee replacement; usually @6 weeks. After surgery you need to take an antibiotic before any dental or GI procedures and avoid high impact activities. ...Read more

What is it like going through a partial knee replacement?

Quick recovery: The procedure usually takes about 1 hour and patients often stay one night in the hospital. Patients need crutches and pain meds for 1-2 weeks. Many patients return to work after 2 weeks. Low impact exercises such as stationary bike are started at 2 weeks. People typically are sore from weeks 2-6 but feel as good or better than preop. Patients often return to golf and tennis at 6-12 weeks. ...Read more

I am having a partial knee replacement, what pain and suffering to expect?

I am having a partial knee replacement, what pain and suffering to expect?

Minimal: Partial knee replacement done well should be mild to moderately painful for about a week. By two weeks it should be tapering off. The pain is far less than total knee replacement if done well and with minimal incisions. Post op therapy is very minimal for partial knee replacements. The key to success is precision installation. Look into robotic installation which can be done minimally invasive. ...Read more

How long after a partial knee replacement will the swelling resolve?

Weeks: Swelling of the knee can take a few weeks to resolve. It should be iced aggressively. If it is not improving or if it is red, warm, draining or you have a fever, it needs to be seen by your doctor immediately. Swelling of the leg also needs to be checked to rule out for blood clots. ...Read more

What is the common response to rehabilitation after partial knee replacement?

What is the common response to rehabilitation after partial knee replacement?

Motion: The common response is to improve range motion, decrease swelling, and decrease incidence of scar tissue while training as an athlete to become fitter and stronger. We believe that rehabilitation begins before surgery to have the highest tissue quality possible and to be as fit and strong as possible before surgery to have better outcomes after surgery. ...Read more

What can I expect if I get partial knee replacement?

Partial knee: You can expect relief from arthritis that involves only one compartment of the knee. The recovery is quick and patients often return to work after 2 weeks and get back to low impact sports by 6-8 weeks. However, 35 is young for a partial knee. The implant has 85-90% chance of lasting 10 years but the risks of revision are higher in young patients. Make sure there are no other options. ...Read more
