Making The Knee Incision

First-ever surgery tests implant device to prevent knee replacements

The surgeon makes an incision across the front of your knee to gain access to the patella, more commonly referred to as the kneecap. In a traditional knee replacement, the incision is usually about 8 to 10 inches long. In minimally invasive knee surgery, the incision is usually about 4 to 6 inches long. The jury is still out as to whether or not the pros of the smaller scar outweigh the cons of a smaller surgical area. Talk to your doctor about which procedure is right for you.

Preparing Patients For Recovery

At HSS, an interdisciplinary team of clinicians, researchers, and administrators works to fine-tune the pathway of care for knee replacement, from preoperative screening through rehabilitation. People who are healthy and prepared prior to surgery are more likely to succeed in rehabilitation following surgery and have better overall results.

, a rheumatologist and director of the Perioperative Medicine Division, and orthopedic surgeon , have initiated a study of 100 knee replacement patients who have been identified as good candidates for a new program that includes increased health monitoring prior to surgery and an innovative step of a presurgical home visit by a physical therapist. The study will determine if this pre-care will increase the chances of patients successfully returning home with appropriate home-based and outpatient rehabilitation following surgery, as opposed to going to an inpatient rehabilitation facility.

For many patients, going home and resuming normal life activities is their best option. The study will determine if receiving more support prior to surgery will result in a smooth transition home, says Dr. Russell.

A Game Changer: Discovering The Modern Total Knee

In 1969, when John N. Insall, MD, became the chief of the HSS Knee Clinic, there was no reliable knee implant on the market. When patients had debilitating knee arthritis, their best option was often the temporary relief of pain medication. Seeking new hope for their patients, Dr. Insall worked with HSS surgeons Chitranjan Ranawat, MD, Allan E. Inglis, MD, and biomechanical engineer Peter Walker, PhD, to design and develop the modern total knee implant, called the total condylar knee. Dr. Insall and Dr. Ranawat first used the total condylar knee with patients in 1974.

For the first time, a knee implant recreated the way a real knee works, allowing patients to move naturally and without pain. This knee was a game changer, says Chief Scientific Officer , Richard L. Menschel Research Chair.

The total condylar knee gave patients with advanced a chance to live without pain. The total condylar was the first implant to address all aspects of the knee with anatomically shaped parts. Previous implants were cumbersome for surgeons to implant. Surgeons across the country appreciated the total condylars design and began to use it with their patients.

Can A Knee Replacement Last 30 Years

Total knee joint replacement surgery has been performed for about 30 years. Over those years, incremental improvements in materials and designs have raised the expected life of the new knees to 10 to 20 years. Two developments are causing a noteworthy change in patients and expectations.

Posterior Cruciate Ligament Retention Versus Substitution

All knee arthroplasties require anterior cruciate ligament removal, but retention of the posterior cruciate ligament depends on the type of arthroplasty. The preservation type, in which posterior cruciate ligament is preserved, is considered better than the replacement type for performing functions, such as, climbing stairs, and has the advantage of simplifying revision surgery due to less loss of bone . However, knee joints with degenerative arthritis usually show soft tissue contracture, and when preserving the posterior cruciate ligament, the soft tissue balance is not easy to achieve, which possibly increases the risk of early failure due to polyethylene insert overloading caused by posterior cruciate ligament unbalanced tension .

Constrained Condylar Knee Prostheses

Revision total knee arthroplasty is often associated with poorer outcomes due to bone loss and ligament damage, which can result in ligamentous laxity and imbalance. A constrained condylar knee design was developed to resist coronal moments in the plane caused by soft-tissue deficiency. Constrained condylar knee designs have the advantage of allowing changes in the center of rotation during flexion, and thereby, theoretically impart less tangential anterior-posterior stress across the prosthetic interface . An early model of constrained condylar knee design was proposed by Insall et al, although similar to posterior cruciate ligament substitution knee arthroplasty, the polyethylene post is thicker and longer, which provides stability for valgus and varus movements as well as not posterior movements . These early models were developed into Legacy Constrained Condylar Knee . Excessive constraint is a problem when the LCCK is used and this causes failure by loosening the prosthesis. Thus, in difficult knee arthroplasty cases, usage may be determined during surgery by taking into consideration the need for constraint. For example, in severe valgus knee joints, the LCCK polyethylene insert may be a good candidate, but posterior cruciate substitution tibial bearing is recommended over the constrained type.

Are There Any Reasons Why I Cant Have A Knee Replacement

Unfortunately, some people may not be able to have a knee replacement even though their arthritis is very bad. This may be because:

  • your thigh muscles are very weak and may not be able to support your new knee joint
  • there are deep or long-lasting open sores in the skin below your knee, increasing your risk of infection.

How Your New Knee Is Different

Improvement of knee motion is a goal of total knee replacement, but restoration of full motion is uncommon. The motion of your knee replacement after surgery can be predicted by the range of motion you have in your knee before surgery. Most patients can expect to be able to almost fully straighten the replaced knee and to bend the knee sufficiently to climb stairs and get in and out of a car. Kneeling is sometimes uncomfortable, but it is not harmful.

Most people feel some numbness in the skin around your incision. You also may feel some stiffness, particularly with excessive bending activities.

Most people also feel or hear some clicking of the metal and plastic with knee bending or walking. This is a normal. These differences often diminish with time and most patients find them to be tolerable when compared with the pain and limited function they experienced prior to surgery.

Your new knee may activate metal detectors required for security in airports and some buildings. Tell the security agent about your knee replacement if the alarm is activated.

Minimally Invasive Total Knee Replacement

Left Total Knee Replacement First Physical Therapy Session (Day of Surgery)

Some medical centers perform minimally invasive surgery for a total knee replacement, also called min-incision joint replacement.

This surgery allows surgeons to cut less muscle and tissue, which leads to less blood loss, increased range of motion and a shorter hospital stay. Many patients go home the same day and the recovery process is usually much quicker than traditional total knee surgery.

However, minimally invasive knee replacement is not for everyone. In general, the best candidates for this kind of surgery are younger and in better health. Older patients, those who are overweight or patients who have undergone knee surgeries in the past may be less suitable for minimal incision procedures.

Because it uses a much smaller incision, minimally invasive knee replacements have a higher risk for poor implant placement compared to traditional total knee surgery. Other common complications include nerve and artery injuries, wound healing problems and infection.

Only specialized medical centers typically offer this surgical option. An orthopaedic surgeon should explain the complete process, the benefits and the potential risks to help the patient decide which surgical option is the best fit.

No Additional Costs For Robotics

Since Da Vinci has been launched in 2000, there are already long-term studies on its effectiveness. An important one from 2019 has been conducted by the Martini Clinic Hamburg. It is renowned worldwide, even patients from Ghana go there for an operation. The results of the study show: patients who had a robotic-assisted surgery dont feel better in the long term, but just as well as patients who underwent conventional surgery. If you still want to be operated with the Da Vinci robot at the Martini Clinic, you have to pay 2,000 euros yourself. There are no additional costs for robotic-assisted knee surgery.

Patients associate higher precision with the surgical robots and hope for a better outcome. Thats why robots are also a marketing tool, lets not forget that, says Thom Rasche, medical technology expert and managing partner at venture capital investor Earlybird Health. He would recommend the acquisition of a surgical robot for knee surgery to hospitals specialized in endoprosthetics to position themselves on the market over the competition. He doubts whether the investment is worthwhile for a smaller hospital.

Sankt Marien Hospital Buer in Gelsenkirchen is one of these smaller hospitals. Nevertheless, Awakowicz believes that purchasing the robot was the right decision. Our clinic is situated in the middle of the Ruhrgebiet and the competition is fierce. If I can convince patients with the robot to come to us, it will be a worthwhile investment.

Who Was The First Hospital To Do Total Knee Replacement

HSS surgeons invented the first modern total knee replacement in the 1970s and have continually improved on surgical techniques, technology and prosthetic materials ever since. In 2020, HSS became the first hospital in the United States to complete a total knee replacement using augmented reality assistance. * What is knee replacement surgery?

When A Knee Replacement Is Needed

The usual reason that someone has a knee replacement is because they have very painful arthritis in their knee.

You should always bear in mind that a knee replacement is a major operation and you should really only be considering it when you have run out of other options. A doctor can tell you that you have arthritis in your knee and they can tell you that you could have a knee replacement but only you can decide if the time is right for you. Most people who decide to have a knee replacement are already taking painkillers every day but are still not able to walk far and need to use a stick.

Looking at all of the research on knee replacements , it would seem that the people who do best after a knee replacement are the ones with severe arthritis but not so bad that the joint is completely destroyed. This could be because it’s really important to have strong muscles around the knee in order to make the best recovery and people who have the most advanced disease tend to have very weak leg muscles.

Symptoms will often vary from day to day for no apparent reason. This is really common. Some people think their symptoms vary according to the weather or according to how much they have been doing – but it can be completely random.

Sometimes you will be aware of a grating or grinding feeling coming from your knee. This is called crepitus. On its own this does not necessarily indicate a serious problem with your knee.

Pain following total knee replacement has come a long way over the last 10-15 years with increased use of regional nerve blocks, spinal blocks, and various other modalities used for pain control. Early range of motion and rapid rehab protocols are also designed to reduce early stiffness and pain, making the procedure in general much less painful than in years past. However, patients handle and perceive pain differently and as such some patients may have relatively mild pain following the procedure while others have a more difficult time.

How Long Does It Take To Recover From A Knee Replacement

For most people, it will take three months after surgery before they can do their regular activities again. It may take six months to a year before your knee regains full function.

How quickly you recover from surgery will depend on your:

  • age,
  • how strong your knee was before surgery, and
  • whether you have other health problems like diabetes or rheumatoid arthritis.

These diseases weaken your immune system and can slow down healing.

Do I Need Physical Therapy And If So For How Long

Most patients do require outpatient physical therapy following knee replacement. A skilled therapist can accelerate the rehabilitation as well as make the process more efficient with the use of dedicated machines and therapeutic modalities. Depending on a patient’s preoperative condition, physical therapy is beneficial for up to 3 months and rarely longer. The amount of therapy needed depends upon a patient’s pre-op conditioning, motivation, and general health.

What Can I Do/not Do After Surgery

Restrictions following knee replacement are generally few and should be discussed with your surgeon. Many patients following knee replacement will have some difficulty kneeling on the operative knee. Most patients become less aware of this with time but will always have a general perception that the knee is artificial and doesn’t really feel like a normal knee. Most patients are able to return to preoperative activities and work but may have some difficulty performing heavy labor such as construction or farming. Most sporting activities are fine with the exception of running or jumping. Traveling should be not be affected by a joint replacement after the first 4-6 weeks when most surgeons advise against prolonged seated travel or flying due to increased risk of blood clot.

I Had A Knee Replacement A Week Ago Heres What Its Really Like

Feb 9, 2017 | Patient

This week, were proud to share the knee replacement story of 74-year-old, Allan. As of this writing, Allan is one week into his knee replacement recovery. We spoke with Allan to check-in on his recovery and to get an idea of what its really like to be fresh out of surgery. Really, we wanted to find out directly from Allan if surgery is as bad as one expects and to see if anything about the process surprised him.

As we began our chat, Allan was insistent that there was nothing remarkable or extraordinary about his story. Although his journey towards a knee replacement may not be filled with the twists, turns, and complications of 29-year-old Travis story, his story captures an important message: What you put into something, you will get out. This was a line that Allan expressed a few times throughout our conversation and is the reason we believe his story is so inspirational for those awaiting a hip or knee replacement.

Like many of you, 74-year old Allan is retired after a fast-paced career. He enjoyed an active lifestyle of travel, cricket and table tennis. It was in the late 1990s when Allan was in his mid-50s that he really began to notice some problems with his knees and began to experience joint pain. Allan had to curb his active lifestyle, trading in cricket for golf.

An Artificial Meniscus May Soon Be Available

If you are suffering from knee pain following meniscus surgery or are without viable treatment options, the NUsurface®Meniscus Implant may provide an alternative option, once it has approval from the U.S. Food and Drug Administration. NUsurfaces design mimics the function of the natural meniscus and redistributes weight across the knee joint. The implant is made from medical grade plastic and, as a result of its unique materials, composite structure, and design, does not require fixation to bone or soft tissues.

NUsurface can potentially address the treatment gap of those who are too old for meniscus repair and too young for total knee arthroplasty. U.S. clinical trials completed enrollment in June 2018, and the company expects to file for U.S. Food and Drug Administration approval soon.

If you have any questions about Total Knee Replacement, feel free to email Dr. Manner at , or schedule an appointment at 425.646.7777.

OverviewKnee replacement is a surgical procedure that decreases pain and improves the quality of life in many patients with severe knee arthritis. Typically patients undergo this surgery after non-operative treatments have failed to provide relief of arthritic symptoms. Surgeons have performed knee replacements for over three decades generally with excellent results most reports have ten-year success rates in excess of 90 percent.

Broadly speaking there are two types ways to insert a total knee replacement: the traditional approach and the newer minimally-invasive approach.

Traditional total knee replacement involves a roughly 8 incision over the knee a hospital stay of 3-5 days and sometimes an additional stay in an inpatient rehabilitation setting before going home. The recovery period typically lasting from one to three months. The large majority of patients report substantial or complete relief of their arthritic symptoms once they have recovered from a total knee replacement.

The main potential benefits of this new technique include:

  • . This may be a function of the smaller incision and the fact that the incision stays out of the important quadriceps muscle/tendon group.
  • The major apparent risks of the procedure compared to traditional total knee replacement:
