OrthoVision Clinic has one of the best Joint Replacement Surgeons in Noida who provides Hip,knee , Shoulder Replacement Surgery, at an Affordable cost with High Success Rate.

Changing the surface of joints is Joint replacement

Joint replacement may be needed when:

• Restricted mobility due to severe pain in the joint
• In carcinomas of the joint
• Accidental joint injuries

Most commonly replaced joints are Hip, Knee, Shoulder, Elbow, Ankle.

Joint replacement also known as Arthroplasty can be partial or total depending upon the pathology.

Metal or plastic. This is the most common type of implant articulation. It involves a Metallic Femoral component that rides on a Polyethylene plastic spacer attached to the Tibial component.

The metals commonly used include

1. Cobalt-Chromium
2. Titanium
3. Zirconium
4. Oxinium

Advantages

Least expensive type of implant Longest track record for safety and implant life span.

Disadvantages

Osteolysis  An immune reaction triggered by tiny particles that wear away from the spacer. It can cause the bone to break down, leading to loosening and failure of the Osteolysis implant. Advances in manufacturing have significantly reduced the rate of wear in the plastic. Development of Highly Cross-linked Polyethylene or Vitamin E Poly has highly reduced the wear.

The golden knee replacement surgery in thane is a blessing for the people who have metal allergy. These knee implants have enhanced surface coating of Titanium Niobium Nitride (TiNiN). This coating gives the implant a golden colored look & improves Hip & knee replacement surgery’s longevity and performance. We at OrthoVision Clinic have Dr Abhishek Haldar who specialises in Computer Navigated Minimally Invasive Knee Replacement Surgery.

Total knee replacement (TKR) surgery has become a commonly performed and highly successful surgical procedure for end stage knee arthritis. Recent technological innovations have improved both early and long term results and survivorship of the implanted joints. New implant designs have provided for greater and more normal range of motion and more natural feel. Better understanding of the role of the ligaments about the knee has resulted in improved joint stability and balancing. Minimally invasive surgical techniques are evolving to speed the rehabilitation process, shorter hospital stays, less time on a walker, and a quicker return to normal function. Less postoperative pain and a smaller scar (improved cosmesis) are also by-products of minimally invasive surgery.

Computer navigation guiding the surgeon through the journey of implantation of a total knee replacement just like the GPS enabled navigation guiding the driver throughout the journey . Through infrared sensing of patient anatomy using trackers attached intraoperatively to patients thigh(Femur) and the leg (Tibia) bone, the computer can precisely advise the surgeon as to the exact location new knee implants should be positioned. This technology carries the promise of improving the precision of total knee replacement surgery, thus, improving the short and long-term performance of the knee replacement as one of the most important cause of failure of a Total Joint Arthroplasty is Malalignment.

There are several potential advantages of computer navigation in knee replacement surgery.

1. Incisions can be made smaller and the soft tissue dissection can be kept less invasive with computer navigation guidance.
2. Computer navigation guidance eliminates the need for a rod to be placed inside the intramedullary (IM) canal of the bone which in turn reduces the risks of fat embolism.
3. At the completion of total knee replacement surgery balancing the ligaments surrounding the knee has always been the most difficult and “subjective” part of knee arthroplasty. In conventional surgery the knee ligaments are balanced chiefly by the surgeons “feel” to determine if the ligaments are appropriately taut. Though experienced surgeons can achieve excellent ligament balance in most cases, reproducibility is difficult and results are subjective. With computer navigation, ligament balancing can potentially be quantified to the nearest millimetre of ligament laxity or tautness. This, in the end, may prove to be computer navigation’s greatest advantage over conventional surgery.
4. In Total Knee Replacement surgery if there is significant deformity in the femur above the knee or in the tibia below the knee (Extra Articular Deformity) conventional alignment systems can be difficult or impossible to use. This is due to the fact that intramedullary systems require an unobstructed femoral and tibial canal. Similarly if as a result of previous surgery any hardware is present such as plates, screws or rods in the bone blocking the femoral or tibial canal, conventional alignment systems often cannot be utilized. With computer navigation systems deformity and /or the presence of hardware provides no obstacle since access to the intramedullary canal is not a requirement. Thus, patients with bony deformity or hardware above or below the knee are ideal candidates for utilizing computer navigation guidance systems.
5. Studies have shown that computer navigation eliminates alignment “outliers”. Experienced surgeons using conventional alignment systems and  Navigation can accurately align the knee replacement in over 90 – 95% of cases. However, studies show that in as much as 5 to 10% of surgeries, postoperative knee alignment will be less than ideal. These patients in this 5 to 10% group are considered “outliers”. It is felt that computer navigation’s accuracy can help the surgeon shrink this percentage of postoperative alignment outliers.

There are some concerns regarding use of computer navigation TKR.

1. The chief disadvantage of computer navigation surgery is the increased cost of the procedure. There is considerable up­front capital expense to the hospital to purchase these computer navigation systems. Many leading joint replacement hospitals, in an effort to provide cutting edge technology and best available care to patients, have indeed acquired navigation systems. These costs are not passed on to patients (computer navigation surgery does not cost the patient anything additional). And since insurance companies and Medicare typically do not reimburse the hospitals more for surgery utilizing computer navigation, hospitals are forced to absorb the additional expense. Though this is not necessarily the problem of any individual patient facing surgery, the increased costs of technologic advances adding to overall health care costs are of concern to us all.
2. A second disadvantage of computer navigation surgery is the potential increased surgical time required to perform the procedure. Increasing surgical time theoretically increases infection risk due to the surgical wound being opened longer. Surgeons experienced in the use of computer navigation systems may increase the length of the surgical procedure by about 10 to 15 minutes. Though it is well known that dramatic increases in surgical time do increase the risk of infection, studies thus far have not shown a greater infection rate in computer navigation surgeries (presumably due to the relatively modest increase in surgical time).

Computer navigation in knee replacement surgery is the technological innovation aimed at improving the accuracy of prosthetic implantation and at minimizing the surgical exposure. Though conventional surgical techniques have been extremely successful, use of computer navigation may improve the already excellent results benefiting thousands of patients annually.
