Knee Replacement in Hyderabad is The Best Way to Recover from Osteoarthritis
Osteoarthritis causes damage to the articular cartilage of the knee. This makes the surface of the tibial and femoral bone irregular, causing them to rub against each other, which is extremely painful. The only way to treat is through knee replacement.
The knee prosthesis is an artificial joint system made of metal alloys and plastic materials, intended to replace the natural knee in all its functions.
The best knee replacement surgeon in Hyderabad is Dr. JVS Vidya Sagar, who has performed the largest number of arthroscopic surgeries in the world. With 37 years of experience, he is considered the finest in his field and is attached to Global Hospitals, Hyderabad. The cost of knee surgery in India ranges between USD 4000 and 6000.
Types of knee prosthesis
There are two main types of knee prosthesis -
· the total prostheses , called so because replacing the entire articulation sick;
· the unicompartmental prosthesis , which instead replace only one joint compartment, usually the internal one.
In both cases, these orthopedic prostheses consist of three distinct components -
· a metallic femoral component
· a tibial metal component
· an intermediate component which is a plastic insert
In some patients the patella is also replaced.
The excellent results achieved in the last few years by biomedical engineering have led to a clear evolution of knee prosthetic implants that has affected the morphology of the models, the optimization of the components and the quality of the materials.
This allows surgeons to use biocompatible prostheses, better tolerated by the body. In some cases, against particular forms of allergies to certain materials, hypoallergenic prostheses can be used. Due to their particular design, the new prosthetic systems allow a superior postoperative range of movement compared to the past.
Knee arthroplasty surgery
In the case of a prosthetic implant with joint replacement, the goal of surgery is to achieve optimal alignment with an implant that is well balanced and guarantees a satisfactory range of motion at the new knee.
The patient is admitted the day before the operation to prepare preoperative examinations and to visit the anesthetic doctor.
The operation is performed in the great majority of cases in peridural (or spinal) anesthesia or under general anesthesia. Based on the patient's general condition, the anesthesiologist will decide the chosen method during the preoperative interview, in order to guarantee adequate postoperative analgesia for the patient.
The total knee replacement procedure lasts from 1 to 2 hours. The skin incision is about 10 cm long on the front of the knee. When possible it is best to operate with a minimally invasive surgical technique, damaging the least possible amount of tissues, with consequent lower blood loss and faster functional recovery.
The most delicate part of the procedure is the positioning of the prosthesis. The ends of the femur and tibia are meticulously prepared to receive the selected prosthetic implant. To make the incision and position the prosthesis, the surgeon uses special instruments and alignment guides to respect the biomechanical axis. Computer-assisted navigation is increasingly used to minimize errors in alignment or rotation of prosthetic components.
Regarding the duration of the knee prosthesis, statistically, after 15 years from their implantation, more than 95% of the prostheses are still able to function well. In some cases, it may be necessary to perform a revision or replacement of the total prosthesis or one of its components in the event of premature wear or detachment.
Prosthetic knee rehabilitation
Physiotherapy begins the day after the operation. The knee is tested by putting the patient on crutches. Within a few days, the patient is able to walk on his own.
The length of stay varies from patient to patient but usually hospitalization lasts from 4 to 6 days.
Once back at home, the patient will have to continue physiotherapy at his home or in a clinic specializing in rehabilitation.
Complete knee performance is achieved not earlier than the 6th postoperative month. The postoperative checks are performed after three months and a year.
