In the endeavor of providing pain free movement to all our hip patients, we have added a 4th dimension to hip replacement surgery.
Unlike knee replacement, during hip replacement surgery we need to work in depth, of ball & socket joint.
Correct placement of artificial socket requires 360 degree visions.
The 360 degree vision of the socket is usually difficult while operating from one side.
We have a team of highly qualified joint replacement surgeons during surgery standing on either side of patient so, 360 degree visualization of socket becomes possible.
This 4th dimension of high qualified team of 2 surgeons work for the 100% outcome of surgery.
We plan life of patient not hip replacement
The international data suggests that now more & more arthritis of hip is seen in a very younger age group of patients. In our practice about 50% of patients are below 50 years of age. & to our surprise patients below age of 35 years constitute 25% of the total work load.
Average life of an artificial hip implant is about 20 years. Also average activity level and demand from artificial hip is very high in patients of younger age group. So, the life of artificial implant is relatively less in younger patients.
So, it becomes compulsory to go for implant selection in such a way that
1. It sustains the demand of young individual for 20 and more years.
2. If reoperation is required then it should be relatively easily.
3. Patients natural bone has to be maximally preserved.
This is how we can plan 40 to 50 years of life yet to be lived happily by a young hip sufferer.
Guidelines for life with artificial hip
Viroc has a team of 5 qualified counsellors and a detailed counselling module which provides the following guidance.
1. Disease process and remedies at each stage of hip disease
2. Self care of hip pain
3. Do’s & Don’ts of personal, social and professional life.
4. Basket of implant selection taking into consideration age, disease, bone quality and occupation of patient.
5. Life with artificial hip.
Painful hip to artificial painless hip
Don’t stop here! We give life time support by our Holistic approach so then artificial painless hip becomes a happy hip replacement and further to a productive hip replacement for the family and society.

Artificial Hip Joint Selection
Hip replacements are among the most common orthopedic procedures. When a hip replacement is performed, the arthritic, damaged hip joint is removed. The ball-and-socket hip joint is then replaced with an artificial implant. The materials used in the implant depend on several factors, including the age of the patient, the activity level of the patient, and the surgeon’s preference.
Below are brief descriptions of some of the most commonly used hip replacement implants. Not all implants are options for all patients. These are general statements about the different implants; if you have specific questions about a particular implant you must discuss this with your doctor!
TYPE OF FIXATION
Cemented had traditionally been used but in the 1980’s a uncemented design was developed. The cementless design is a porous implant. The intent is, through biologic fixation, that bone grows into and through the pores in the implant, thereby securing it.
The cementless joint replacements are expected to reduce the chance of infection and loosening of the prosthesis, which are the two major complications of hip replacement surgery. However, indicates that both the cemented and cement less joints do very well.
Patients having hip replacement surgery experience significant pain relief and improved range of motion
Cemented prosthesis: –
in this process the prosthesis is fixed to the bone with the help of special bone cement. In that variety only available in head having 2 types metal & ceramic head.
The design of uncemented prosthesis is a porous implant. The intent is,
through biologic fixation, that bone grows into and through the pores in the implant./p>
Advantage in uncemented fixation is that bone loss will not occur despite loosening, in contrast to the dramatic osteolysis seen in loose cemented implants. A much lower rate of thromboembolism has been shown in uncemented THR.
Type of bearing surfaces in total hip replacement prosthesis:
1). Metal on poly implant:
The metal and plastic implants are the most commonly used hip replacement implants. Both the ball and the socket of the hip joint are replaced with a metal prosthesis, and a plastic spacer is placed in between.
The metals used include titanium, stainless steel, and cobalt chrome. The plastic is called polyethylene. The implant is secured to the bone by one of two methods; it is either press-fit or cemented into place. In the press-fit method, the implant is fit snuggly into the bone, and new bone forms around the implant to secure it in position. When an implant is cemented, special bone cement is used to secure the prosthesis in position.
2). Metal on metal implant:
Metal-on-metal implants use similar materials, but there is no plastic piece inserted between. They are now being withdrawn from the market because of high rate f metallosise related complication.
3). Ceramic on poly implant
The ceramic and poly implant in that the ball of the hip joint are replaced with a ceramic prosthesis, and a plastic spacer is placed in between.
4). Ceramic on ceramic implant:
Ceramic-on-ceramic implants are designed to be the most resistant to wear of all available hip replacement implants. They wear even less than the metal-on-metal implants. Ceramics are more scratch resistant and smoother than any of these other implant materials.
Why do you have hip pain?
Pain is a signal that the body has been damaged or something is wrong.
Pain occurs when nerve fibers (pain fibers) get stimulated; the spinal cord is the main route for all pain massages to the brain, where pain is then registered.
The whole concept of pain in any joint is associated with irritation/stimulation of these pain fibers.
Joint cartilage do not have this pain fibres, so we do not have pain during day to day activities. when the cartilage gets damaged due to any hip disease , the underlying bone gets exposed and starts rubbing with each other ie. acetabulam& head of femur rub with each other so, pain fibers in this bone gets activated & patient brain gets the pain signals, & suffers from hip pain.
We are a team of two joint replacement surgeons, who are a part of only 15% of surgeon across the globe, & only centre in Vadodara offering bone & ligament preserving knee replacement surgery
