FREQUENTLY ASKED QUESTIONS FOR MATRIX ARTHROPLASTY WITH MINIMAL INVASIVE TECHNIQUES (M.I.S)
It is the latest technological development in total arthroplasty, specifically designed for the knee joint. The digital imaging of the diseased joint passes directly into the surgeon’s field of vision through specific augmented reality glasses and is fully harmonized with the natural environment in the operating room, eliminating human error and offering an excellent surgical result individually per patient.
In everyday practice, by the word “success” we mean the patient’s ability to answer affirmatively the following three questions.
- Are you satisfied with your operation?
- Is the result meets your expectations?
- Would you do the same operation again?
In fact, 97-98% of our patients answer all three questions affirmatively, one year post-operatively.
Recovery time is individualized. In general we would say that you need crutches only during the first 1-2 days after surgery. External aids are needed most for maintaining the balance of the body and less for full weight-bearing of the operated limb. Once the patient has gained security, comfort and self-confidence, he can walk freely. Progression is clinically daily and most patients walk completely freely and away from home after about 10 days of surgery.
Can I go straight at home, or do I need a specialized physiotherapy center after hospital discharge?
All our patients can go home after leaving the clinic, unless there are other reasons of disability that are not related to the specific operation. Everyone is able to perform his usual daily activities from the very first day of their return home such as get dressed, take a bath, etc. Only in 5% of cases physiotherapy is required at home, since patients can fulfill the physiotherapy protocol expectations during their hospitalization period of time.
It varies from patient to patient and depends on many factors, such as the joint that has been operated on (hip, knee, etc.), the leg that has been operated on (left, right), whether the car is automatic or not, how much muscle strength has been regained and the range of motion of the operated joint. International hip data allow safe driving after the first 6 weeks after arthroplasty, however they do not take into account the cutting-edge, minimally invasive surgical techniques and implants we use nowadays. For example, a patient who has had surgery on his left knee, walks freely, has almost full muscle strength and drives an automatic car, can drive comfortably and safely from the 10th day postoperatively. In any case, the treating physician should be asked, because each case is unique.
You can travel as soon as you feel comfortable after your surgery. Usually most patients after leaving the clinic, can travel by car and / or airplane, using anticoagulant therapy combined with specific anticoagulation socks, with the instruction they will get up and walk at the corridor at regular intervals, to minimize the risk of venous thrombosis. Transatlantic travel is usually prohibited for a period of about 6 weeks and for the first half of the year, you should consult your doctor before traveling.
It depends on the type of work you do. If you work in an office, you can return back safely after the second week post-operatively. If your type of work is different it usually takes 6-8 weeks to return back safely. In any case, we would say that the time to return to work is individualized.
You can safely return to most of your daily activities such as walking, gardening, golfing and cycling. Some of the best activities to help the affected joint stretch are swimming and stationary cycling.
Skiing is allowed for patients who have previous experience of accident risk avoidance.
Experience varies from patient to patient. The modern, personalized prosthetic materials we use, with contact interfaces such as “ceramic to ceramic” or even better “ceramic to biological plastic”, ensure 85-95% greater longevity of implant survival compared to conventional arthroplasty that has a lifespan of approximately 10 -15 years. With good maintenance, avoidance of daily stress and maintaining body weight at normal levels, the survival of prosthetic materials with this technique exceeds to 25-30 years post-operatively.
All anticoagulants that affect blood clotting time, including aspirin, should be discontinued approximately one week before surgery, or replaced with low-molecular-weight heparin, as determined by the treating physician.
What are the major advantages of MATRIX arthroplasty and personalized implants in combination with minimally invasive surgery (MIS)?
What is very important in a total arthroplasty is on the one hand that the prosthetic materials will not undergo an oxidative reaction and/or are subjective to wear in a short period of time post-operatively, and on the other hand that they are placed in a proper manner, exactly in the anatomorphological dimensions of each patient separately and in excellent space orientation , so as to simulate normal function of the joint. The augmented reality offered to MATRIX arthroplasty through the specific designed glasses in the surgeon’s eyes, perfectly simulate the virtual in relation to the real environment of the bones and ligaments through specific sensors and thus can ensure excellent placement of the prosthetic materials that are now lightweight, hypoallergenic on a personalized basis while minimally invasive techniques ensure a fast surgery, bloodless, with minimal postoperative pain, immediate mobilization, minimization of hospitalization time and faster recovery.
QUESTIONS ABOUT THE SURGERY
After the first change of wound dressings, usually on the 2nd postoperative day you can take a bath without fear, since the wound will be covered with a waterproof bandage.
Usually after suture removal (15-17 days postoperatively) and having the wound dry as a pre-requisite.
No. Especially in the knee joint, MATRIX arthroplasty with the minimally invasive technique we use, achieves excellent soft tissue balance and the non-traumatic repair of the wound we perform, allows all patients to gain a range of motion from 0-90 degrees for the Day 1 a postoperatively .
The sutures do not need to be removed, as the wound has been closed using a transdermal suture with an absorbable suture. You will be trained to remove both ends of the suture by yourself 15-17 days after surgery, without having to visit a doctor or nurse.
The surgical technique that we perform, permits the patient to feel no pain after leaving the clinic. All patients take simple oral drugs consisting of paracetamol with codeine, without the addition of any anti-inflammatory drugs. In case of pain, we can add specific transdermal patches with nanocrystals that carry the biological message in the body and cause the release of endorphins, which immediately respond to pain.
For 30 days you will take an oral anticoagulant and wear specific anticoagulant socks.
Of course you can. On the last day of your hospitalization you will be trained well by our physiotherapist in climbing and lowering a ladder. Usually 30 days after the operation you will be able to go up and down stairs in a more normal way.
