Nagpur: Noted consultant orth-opaedic surgeon Dr H J Sangtani performed first ever ‘custom’ knee replacement surgery in Vidarbha at the Ortho Relief Hospital and Research Centre, Dhantoli in last week of December, 2014. The implant used was Johnson &Johnson’s ‘Attune’ knee system.
This follows Dr Sangtani’s track record of pioneering advancements in the field of joint replacement surgery. These include performing in central India first ever knee replacement, hip resurfacing, computer assisted surgery and elbow replacement (using sloppy joint). Dr Sangtani is a leading user of J&J’s mobile bearing high flexion (greater bending) knee implants such as RP-F & PS150 in all of India.
While a knee replacement is globally a highly successful procedure, data has shown that patients are not completely satisfied (global satisfaction rates of 82 per cent) with their implants because of a number of issues like instability while coming down stairs resulting in lack of confidence, as well as post operative knee pain and the speed of recovery. With the Attune knee, these issues have become a thing of past because of the 13 new patented technologies offered.
The availability of an extensive range of implants for Asian patients enables surgeon to find the closest match to patient’s natural anatomy and ensures stable, flexible motion.
Attune has been designed in such a way that surgeons can feel the stability of the implant intra-operatively. The knee system also offers a larger degree of customization to address anatomical structure of people of various ethnicities around the globe – i tomes in 10 tibia and 10 femur sizes.
Superior stability and decreased post-operative pain
The design provides superior stability and imparts confidence especially during activities like walking over rough ground and going up and down stairs. Patients feel more confidence about being able to move about feeling wobbly and unstable as well as not feel knee pain – instability and anterior knee pain are major causes of patient dissatisfaction following a knee replacement procedure.
The Attune knee system uses an advanced polyethylene (plastic) material to act as a spacer that goes in between the tibis (shin bone) and the femur (thigh bone) to replace the cartilage. This material has been extensively tested and shown to have excellent mechanical strength and resistance to wear resulting in an approximate life of implant of 30 years.
In a clinical study, physical therapists noted that Attune knee patients had significantly greater range of motion than other knee replacement patients, both two and six weeks post surgery.
Though the post surgery recovery time is dependent on an individual patient’s pre-existing physical and medical condition, in a clinical study, physical therapists noted that Attune patients physical and medical condition, in a clinical study, physical therapists that Attune patients required significantly less time than other knee replacement patients to meet the necessary criteria to leave the hospital.
