I ASSIST SURGERY

ADVANCE IN KNEE REPLACEMENT

Over the years Knee Joint replacement surgery has emerged as a safe and effective option for the treatment of arthritis. The patients suffering from severe knee pain because of arthritis expect a high quality of life with an enhanced and independent lifestyle after the surgery. Thanks to advances in knee Joint replacement surgery, a trained joint replacement surgeon can perform a surgery with high-performance results. The advances that make a high-performance knee replacement possible are muscle sparing and bone conserving surgical approach. The use of implants with improved designs, improved materials and use of technology to improve surgical precision definitely enhance results.

Bone conserving and Muscle sparing approach

One of the main objectives during a surgery is to conserve bones, muscles and ligaments as much as possible. The use of a minimally invasive surgical approach results in a smaller surgical opening for accessing the knee joint  and less muscle damage. This improves the recovery and significantly reduces pain post surgery.

Improved implant design and material

The advances in the material used to make the implants and the design of the implants is very significant. For example the highly polished cobalt chrome tibial implant has reduced the wear of the polyethylene insert, which increases the life of the replaced Joint. The hi-flexion knees are designed for people who flex their knees more (like sitting cross-legged on the floor) after surgery. The high-flex implant will be able to accommodate the high stresses developed in the joint with more flexion.

Gender Specific Implants

The differences in the female shape and dimensions of bone can better accommodate the gender specific implants, which is meant for ladies. Many women have a much narrower framework than men. Traditional implants can overhang the bone and potentially press on or damage surrounding ligaments and tendons.

The number of women having knee replacement has grown significantly, and orthopedic surgeons began reporting that they were frequently making adjustments during surgery to make traditional implants fit female patients. It became clear that it was time for a knee specifically designed to fit a woman’s anatomy.

Patient Specific Instrumentation

To use or incorporate these surgical advancements it’s imperative that the surgeon should be well trained and an excellent craftsman. But technology has also found new ways of improving precision. Today there is technology available that makes it possible to use patient-specific instruments for surgery. The instruments are designed based on the patient’s anatomy and manufactured. This takes a lead time of around 3 to 4 weeks. Once the instruments arrive from the company the surgery can be performed with precision and ease.

I Assist Surgery

I ASSIST  (i-pad Navigation) Knee is engineered to help achieve repeatable accuracy and alignment in total knee replacement.  I ASSIST Knee is a cutting-edge technology that offers precise intra-operative feedback and alignment validation. Accelerometers and gyroscopes that assist in calculating and validating precise angles drive the technology. This technique is in turn is associated with improved clinical outcomes and increased implant longevity in patients.

Mobility is the key to sharing life’s beautiful moments with your family and joint pain can come in the way. If the knee pain is in an advanced stage and the joint is degenerated beyond repair knee replacement becomes the only treatment option. These advances in Joint replacement help us joint replacement specialists in bringing mobility back into your joints and smiles back into your lives.

Oxinium Knee Implant

OXINIUM (Oxidized Zirconium) is a metal alloy consisting of 97.5% zirconium and 2.5% niobium, two of the most biocompatible metals known to man. The ultimate product is a 5-micron thick ceramic surface on a core of metal. The ceramic is an enhanced surface that is part of the metal substrate rather than an external coating, making it very durable with unusual damage tolerance. Oxinium material combines the best of both metal and ceramics. It is a metal, with excellent fracture toughness like cobalt chrome, but it has a ceramic surface that offers outstanding wear resistance.

Durability

The significant advantage of an Oxinium knee implant is that it is considerably harder. Its high surface hardness minimizes abrasive scratching. This scratch resistance makes the oxinium implant durable and is suitable for patients less than 60 years of age.

Biocompatibility

OXINIUM Oxidized Zirconium is the best choice in joint replacement materials for patients who exhibit metal allergies. OXINIUM implants contain no detectable nickel, the main cause of negative reactions in patients with metal allergies. Zirconium is one of the most biocompatible metals known to man; therefore, patients with metal allergies especially to nickel are able to tolerate this new implant.
