Minimally Invasive Computer Navigation Assisted Knee Replacement

Knee Replacement Surgeon in Delhi NCR and Uttar Pradesh has become a commonly performed and highly successful surgical procedure today. Recent innovations have resulted in further improvements in initial and long-term surgical outcomes. Newer implant designs offer a more general range of motion. Better understanding of the role of ligaments in the knee has resulted in improved joint stability.

The good news for patients is that; Minimally invasive surgical techniques are constantly evolving and speeding up the rehabilitation process. All of these developments mean shorter hospital stays, shorter walking times and a faster return to normal ways of life. Less post-operative pain and minimal scarring (modified cosmos) are direct benefits of minimally invasive surgery.

The latest and perhaps most exciting innovation with computer navigation is that it guides the surgeon through the entire process of total knee replacement surgeon in Noida. Through infrared sensing of the patient’s anatomy, the computerized system shows the surgeon the exact location where the new knee implant should be placed. The technology promises to improve the short- and long-term performance of knee replacements.

Benefits of Computer Navigation Guidance in Knee Replacement Surgery

Incisions can be made smaller and soft tissue dissection can be kept to a minimum. The use of computer navigation replaces other minimally invasive surgical techniques resulting in greater protection of the quadriceps muscle and tendon during surgery. It is protection of the quadriceps muscular system which is a key component of minimally invasive surgery.

Studies show that unlike other systems, bone cuts can be made more accurate and reproducible when guided by computer navigation.

Computer navigation eliminates the need to place the guidance rod inside the intramedullary (IM) canal of the bone. The use of IM rods has been a standard method for aligning cuts over the past two decades and was proven to be quite effective, but there was always the potential for emboli from the bone marrow cavity. In case of computer assisted Knee Replacement Surgeon in Delhi NCR, this risk is eliminated and it is also safe for patients with heart disease, high obesity, diabetes and high blood pressure.

Balancing the ligaments surrounding the knee has always been the most difficult and subjective part of performing Knee Replacement Surgeon in Delhi NCR and Uttar Pradesh. In a traditional surgery, the ligaments of the knee are balanced primarily by the surgeon’s ‘feeling and experience’ to determine whether the ligaments are appropriately tense. With computer navigation, ligament balancing can be determined potentially to the nearest millimeter of ligament laxity or tetanus.

In TKR surgery, if there is significant deformity in the femur above the knee or in the tibia below the knee, using a traditional alignment system may prove difficult or impossible. This is because the intramedullary system requires an unobstructed bone canal. Similarly, if any hardware, such as a plate, screw or rod, is present in the bone that is blocking the bone canal as a result of previous surgery, traditional alignment systems often do not work. With computer navigation systems, the presence of malfunction and/or hardware is not a hindrance as access to the intramedullary canal is not required. Thus, patients with bone deformities or hardware above or below the knee are ideal candidates for using computer navigation guidance systems.

Studies have shown that computer navigation eliminates “outliers” alignments. Even experienced surgeons using traditional alignment systems can accurately align knee replacements in more than 70- 75% of cases. However, Studies show that in 15–20% of surgeries, post-operative knee alignment will be less than ideal. These patients in this 15-20% group are considered “outsiders”. It is realized that the accuracy of computer navigation can help surgeons reduce this percentage of post-operative alignment “outliers”.
