Different patient have different preferences. Some like to know it all, while some just simply wish to have a safe surgery and be done with it. A knee replacement video serves the need of those inquisitive patient or their family members who wish to know exactly what will be done in the surgical procedure. In earlier days, such videos or demonstrations were mostly confined to the medical fraternity and students.

Knee replacement is carried out these days with a variety of techniques. Here, we have curated the most popular videos that can help you understand a specific type of procedure that is suggested to you.

1. Traditional Method – Knee Replacement Video

Video Summary:

In this knee replacement video, Dr. Amit Bhutani demonstrates total knee replacement procedure and its advantages. Knee replacement is a surgical procedure that reduces pain and improves the quality of life in many patients with chronic arthritis of the knees. Typically patients undergo this surgery after non-operative treatments (medicines, physical therapy, steroid injections, etc.) have failed to provide pain relief in arthritis of the knees.

Surgeons have performed knee replacements for over 3 decades generally with excellent results; most reports have 10-year success rates for more than 90% replacements. In total knee replacement traditional or open procedure, surgeon replaces the damaged knee with artificial parts (metal, plastic). This procedure separates the muscles and ligaments around the knee to expose the tissue surrounding the knee joint. The patella (knee cap) moved out of the way, and the ends of the thigh (femur) bone and shin bone (tibia) are cut to fit the prosthesis.

In this traditional joint replacement video, you will see that the surgeon makes an incision that typically measures 7-10 inch in length over the front of the patient’s knee. The quadriceps tendon and muscle entered, and the kneecap is moved out of the way to permit to see the inside of the knee fully and clearly during the surgery. The surgeon removes (cut) the diseased parts of the bones and uses artificial (metal and plastic) parts are used to cap the ends of the bones that form the knee joint, along with the kneecap.

Before closing the incision, the surgeon tests the knee by bending and rotating, to ensure that it is functioning properly or not.

Traditional or open knee replacement involves a 7-10 inch incision over the knee, a hospital stay of 3-6 days, and a recovery phase (during which the patient walks with a walker or cane) typically lasting from 1 to 3 months. It may take even a year or longer for the complete recovery. Life of an implant lasts anywhere from 15 to 20 years.

2. Minimally Invasive Knee Replacement Video

Video Summary:

In this knee replacement video, Dr. Robert Ference demonstrates minimally invasive surgery procedure and its advantages.

A knee replacement operation or arthroscopic knee surgery is a surgical procedure that replaces a diseased knee joint (arthritis) with an artificial metal or plastic replacement parts called the prostheses. The procedure is commonly recommended for elderly patients who are suffering from pain and loss of joint function due to arthritis.

In the typical knee replacement, the surgeon replaces the ends of the thigh bone (femur) and shin bone (tibia) with plastic inserted between them and usually the kneecap (patella).

Minimally Invasive Knee replacement or knee Arthroplasty is an alternative to traditional total knee replacement surgery (open surgery) for some people. Minimally Invasive Knee surgery is similar to traditional or openknee replacement procedure as in both cases, surgeon removes damaged joint and replaces it with an artificial one. However, the minimally invasive procedure uses a3 to6-inch incision, which is much smaller than the traditional eight to 12-inchincision.

In this least invasive knee replacement surgery video, patient’s affected knee is placed in bent position during surgery and the surgeon makes a small incision on the side of the patella (kneecap). Patella and thigh muscles are moved aside to allow the surgeon access to your joint. During the surgery surgeon removes the damaged bone, cartilage, and connective tissue and replaces with an artificial joint (metal or plastic).

In this Minimally Invasive Knee Replacement video surgeon demonstrates that a smaller incision can reduce hospital stay, and enhances quick recovery. There are over 160 types of artificial knee joints. Your surgeon chooses the most appropriate one for you, depending on your age, weight, activity level, and overall health.

3. Uni-compartmental or Partial Knee Replacement Video

Video Summary: 

In this knee replacement video, Dr. H. Kirschenbaum, MD   demonstrates uni-compartmental /partial knee replacement procedure and its advantages.

OA knee may occur in any one of the 3 compartments that make up the knee joint. The medial (inner) and lateral (outer) compartment of the knee is formed by the articulation of the lowest part of the femur (thighbone) and the highest part of the tibia (shinbone). The last compartment of the knee is formed by the patella (kneecap) and the front part of the femur. This is referred to as the patello-femoral joint.

The medial (inner) compartment is the most frequent site of osteoarthritis of the knee, with the disease occurring less frequently in the lateral (outer) compartment.

In this partial knee replacement video, the surgeon replaces just the damaged part of the knee. You may be able to have a partial knee replacement if only one section of your knee is damaged. However, when one part alone is replaced, there is a chance that another part develops arthritis, requiring further surgery.

During the partial or uni-compartmental knee replacement, the orthopedic surgeon makes a small incision to access the affected compartment of the knee. Then the surgeon removes the damaged cartilage and bone tissue surfaces of the tibia and femur in the arthritic area. The surgeon then prepares the surfaces for insertion of the prosthesis components that are specifically fitted for the patient’s joint. The cement is used to secure these components. All structures and surrounding tissues are restored to their anatomical position, and the incision is closed.

Partial or uni-compartmental knee replacement usually involves minimal blood loss (small incision) and a shorter stay in the hospital, so there will be a low rate of complications. Most patients can expect to be back to their regular activities within 3 to 6 weeks. Many patients find that after undergoing physical rehabilitation, they can return to sports, within 6 to 10 weeks.

4. Computer Assisted Knee Replacement Surgery Video

Video Summary:

In this knee replacement video, Dr. Jason E. Lang, MD demonstrates Computer-assisted Total Knee Replacement procedure and its advantages.

In this computer assisted knee replacement surgery video the surgeon replaces damaged cartilage in the knee joint with implants to restore function and eliminate pain. The surgeon plans and performs surgery with a robotic and computer guidance system.

Computer-assisted knee replacement surgery allows the surgeon to an additional measure of care by providing proper alignment of the knee with the bones and with the body, which allows the joint to work better and last longer.

An artificial knee includes a tibial component, femoral component and a spacer that fixed between these components and a small cap that work as a patella. For a successful surgery, these components must be precisely aligned within the joint; even a slight misalignment can through off the patient balance and weight distribution this can cause the components to fail.

The Computer-assisted surgery (CAS) provides surgeon with a patient-specific 3-D model to pre-plan your total knee replacement. During surgery, computer-assisted surgery (CAS) has shown to improve the positioning of implant placement and more properly align the lower limb mechanical axis according to the desired plan. This allows the surgeon to remove only the diseased bone, preserving healthy bone and soft tissue. CAS assists surgeon in positioning the implant based on patient’s anatomy.

Once the computer builds the knee model, it automatically detects the angles of the cuts needed. The computer also sets the size and shape of the position of each of the implant component. The surgeon bends and flexes the joint by visualizing on the computer screen to verify reconstructed joint working properly or not.

At the end of this procedure the incision is closed and bandaged. The patient is kept under observation after the surgery, and physical therapyis begun. The patient walks with the help of crutches or walker for a short period.

5. The iASSIST™ Knee Surgical Technique

Video Summary:

In this total knee replacement video, surgeon demonstrates iASSIST™ Knee Surgical Technique and its advantages.

The iASSIST Knee is an advanced surgical guidance system designed to improve the accuracy and alignment of total knee replacement operation. Zimmer iASSIST Knee helps to assist the surgeon in precisely aligning knee implants to each patient’s unique anatomy, providing a personalised fit and a truly tailored total knee replacement.

The iASSIST Technology comprising small disposable sheath electronics provides accurate alignment validation through an electronic screen, at the site of surgery knee replacement. The technology allows surgeons to perform joint replacement procedures easily as the knee iASSIST technology provides precise intra-operative feedback required for this procedure.
