In 2007, the average age and life expectancy of the French population increase but also the prevalence of hip and knee osteoarthritis.
Approximately 100,000 total hip prostheses and 50,000 total knee arthroplasty
are laid each year.
Although the average age of the French population supporting a total hip replacement is 65, more and more young and active patients are candidates for replacement.
These patients are demanding on the functional performance of their prosthesis as often active and sports.
Currently, the life expectancy of a total hip replacement is more than 20 years (in 90% of cases) and more than 15 years for a total knee replacement, but can we make a life with prosthetics also long a patient who claims to have intense physical activity and without limitation.
To date, no French studies have been published on this subject, so we were forced to review the international literature; which is primarily interested in the total hip and total knee replacement.
In 1960, the first total hip prostheses implanted in patients CHARNLEY had as main objective to treat pain.
Today, this intervention aims, improve joint function by the treatment of pain, stiffness, instability, lameness, to resume normal daily activity and also an activity physical and sports.
According to the recommendations of the "American Association of Sports Medicine" (7,11,12) sport and physical activity is desirable and beneficial for the cardiovascular system and for musculoskeletal patients. Per week, should be performed at least 3 times 20 minutes of physical activity. This leads to an improvement in the general welfare also with a proven physiological benefits on diabetes, hypertension, obesity, coronary heart disease, osteoporosis, and also psychological benefits on anxiety or depression.
We must therefore encourage the sport of a patient with a prosthesis, but can we allow all sports?
Most articles in the literature usually recommend "the high level of impact sports and sports competitions" to avoid increased stress peaks and prosthetic loosening risk. However, there is no scientific study that confirms the reservation, and usually the authorization to practice a sport often based on knowledge and personal experience of the practitioner (surgeons, rheumatologists, sports medicine .... ).
After placement of a prosthesis, mastering sporting gesture and good practice previously practiced sport must allow recovery without limitation few months after surgery.
However it is not recommended to start and discover a sport; it should be considered dangerous and should be banned to the patient.
Some sports are in any case prohibited or strongly discouraged for patients carrying a prosthesis; as the pivot-contact sports, team sports (football, handball), pulse sports (volleyball, sports acrobatics).
However the recommended sports are primarily those where physical activity is not binding on the lower limb joints such as swimming, walking, hiking, cycling, sailing, golf, etc ....
Some sports such as tennis, skiing and golf have been studied in more detail in the international literature.
In 1999, MONT (10) published in "Sports Medicine," a study of patients in practicing tennis club and holders of a total hip replacement. He interviewed 58 patients aged tennis players averaged 70 years (range 47-89 years). Seventeen patients had bilateral total hip arthroplasty 75 operated hips. This article is very interesting because in this population, 14 patients were operated on in order to continue to play tennis. The resumption of their sport was actually about 7 months after surgery, regularly three times a week, and the same level of tennis. The survival rate of the prosthesis was 96% at 8 years back, while in the general population survival to 10 years varies between 95 and 98% survival. SEYLER (13) arrived at the same conclusions in 2006. He did not show a higher rate of failure or takeover among tennis players compared to the general population.
In 2000, GSCHWEND (5), in a prospective study of 10 years, compared 50 patients practicing track skiing and 50 sedentary patients all holders of a total hip replacement at 5 and 10 years of decline. At last follow, he showed more wear among skiers, 2.1 mm wear compared to 1.5 mm wear but without surgical recovery.
A working DUBS (4) in 1985, showed that in a sedentary patient, polyethylene wear of a hip prosthesis is 0.10 mm / year and while it is 0.39mm / year in active patients , the decline in 7 years. Podometric a study showed that polyethylene wear is correlated to the number of daily and 30 polyethylene mm3 are worn per million of cycles not walk, for about 70kg.
So it seems that intense physical activity increases polyethylene wear, and thereby reduces the life of the prosthesis. Nevertheless, the relationship between prosthesis revision rate, age and physical activity level gives, depending on the work, discordant results. Beyond 10 years, the risk of prosthetic recovery seem more often linked to osteolysis phenomena periarticular, independent of mechanical stresses.
For information, the average lifespan of a total hip replacement in the general population is about 94% survival at 15 years and 77% survival at 25 years, while in the population of patients under 50 years so active, survival is 88% at 15 years and 69% at 25 years.
The recommendations made by the members of the "HIP Society" in 1999 (14) are summarized in Table 1. The results of the survey of 54 senior surgeons now possible to help us in the direction of the sport of our patients.
The findings of this study show that licensed sports in patients with a total hip replacement are the low-stress sports, without pivot touch. Must be avoided learning a new sport but can tolerate some sports if the technique is previously known and controlled. Finally, we must warn the patient of the risks of excessive wear in intense sports activity.
This is a patient population most often 65 to 85, more common in women. In younger and active patients, there are conservative surgical treatments such as tibial valgus osteotomy gives good results. The average age of these patients was 52 years. It is therefore not in the same population.
In 2002, MONT (10) studied 33 older tennis players averaged 64 years, carrying a total knee replacement (46 knees). Their surgeons had authorized a resumption of doubles tennis in 45% and single in 21% of cases. The resumption of tennis had been possible approximately 1 year after the intervention, at a frequency of 3 times a week and at the same level. At 7 years of decline, there has been no revision surgery.
Golf was also studied in 1996 by Mallon (8.9). It conducted a survey among 83 golfers holders of a total knee replacement, 92% of these patients returned to golf without limitation. The resumption of golf was possible five months after surgery at a frequency of 3.7 times per week. In 84% of cases, patients showed no discomfort in their sport.
Two more recent studies BOCK (1), and CHAT (2), over 150 patients have shown a gradual evolution of sports activity patients to less stress at sports such as walking, swimming or cycling .
Unlike the hip it appears that the compressive stresses are greatest on the knee prosthesis The biomechanical study KUSTER (6) shown. It evaluated the strengths and constraint surfaces of a total knee prosthesis for 4 sports: cycling, walking, mountain hiking and jogging. He compared three types of total knee prostheses: standard bearing prosthesis, ultra-congruent plate and movable plate. The results are summarized in Table 2 and 3 .They show that the peak stress varies depending on the sport but also the knee flexion angle. Indeed 50 ° of flexion of the knee, this strength in the jogging is 9 times the body weight on the tibiofemoral compartment. It appears therefore the need to promote activities such as cycling and walking and jogging contraindicate see mountain hiking.
The recovery in sport and physical activity after joint replacement is a question often asked by the patient to the surgeon but also the sports doctor and the attending physician.
This literature review should help to assist the practitioner to advise his patient.
The practice of physical activity is desirable for the cardiovascular system and the musculoskeletal system, we must encourage the resumption of a sport but also know the risks. We must focus on endurance activities, recreation, low
stress: walking, swimming, cycling, golf, etc ...
Some sports most at risk may be authorized through a mastery of technical movement and after informing the patient of the risks of wear.

Around a recent need, the treatment of pathologies related to the sport, the former Clinique Saint-François, now Sport Clinic, was taken over by General of Health in 2002. The renewal of the medical staff with surgical team renowned helped to design and implement a medical and scientific project based on the quality of practice. Générale de Santé has worked to support this project, including through an intense program of renovation and careful management of human resources.
Today, the sport of Clinic is a hyper-specialized private institution under agreement in orthopedics, traumatology and sports medicine.
Medical and surgical consultations highly specialized, a reference imaging and functional rehabilitation recognized competence guarantee our patients the best care for diseases of the musculoskeletal system, either degenerative or related to physical activity.
The rupture of the Achilles tendon in athletes, is a rare event that usually occurs during the 3rd decade in athletes and 4th among the sedentary. The break often occurs when an eccentric effort (Work together a muscle elongation instead of the normal shortening) as a startup, acceleration or landing from a jump. Read more ......
Attention! This is no shock absorbing soles, type "ready to wear" sold in stores. No, they are "haute couture", tailored to your injury and imperfections of your stride. They are made ??"to measure" by a podiatrist sports. He knows the injuries encountered in sports. It does not use cork or leather. It uses synthetic materials flexibility cleverly distributed, which tolerate sweat and mechanical stress.
Iron is essential to your health and performance. It is a central component of hemoglobin. The latter is contained in red blood cells and gives it color. It is the iron that captures oxygen when blood passes through the lungs. It carries the precious gas to muscles. When they arrived, it drops its cargo which then allows the burning of energy substances and muscle contraction.
When you run or when you jump, your heels hit the ground and the fat pad of the foot of the plant is crushed. It is through many blood vessels. These red blood cells burst and release their hemoglobin. Iron is released into the blood and pass into urine.
Muscle contains a twin sister of hemoglobin, myoglobin. The latter also contains a lot of iron which sets some oxygen. This small local reserve allows starting the contraction before the blood vessels do not provide the necessary complement. When you experience aches, your muscle membranes are victims of micro-fissures. Myoglobin and iron leaves the muscle and gaining the blood. The precious metal is eliminated in the urine.
When you make an effort, the majority of blood flow is directed towards your muscles. There remains very little to the digestive tract and the bladder wall. These organs suffer from lack of oxygen and are shaken with every stride. Small areas are damaged and start to bleed. Red blood cells and iron are lost in the feces and in urine.
You enter the assiduous why athletes often lack iron, especially if they do not take care to concoct "menus and recipes" adapted. Sports are even more concerned since all these iron losses are added the massive elimination of blood during menstruation!
That is why it is good to occasionally perform a blood test to assess the stock in body iron. This levy is necessary when it comes to review a state of fatigue. It unnecessary to dose iron in the blood because the body is able to keep within the limits of normal while the reserves are at their lowest! It is necessary to measure levels of "serum ferritin" because this structure is the storage form of iron.
Each sports movement constitutes a solicitation for the bone structure. At each reception process, the tibia runner undergoes vibratory impacts. Unrolling not, the hiker twists slightly small bone in his foot. Even the body-builders, powerfully contracting its muscles, pulls on his bone.
Each strain injures a little bone of sports. Fortunately, during the rest period, the bone trying to rebuild. If time allows, if they bring him the necessary food, it is repaired! It reconstructs even louder than before as if to prepare for new mechanical attacks. This phenomenon is called by coaches cycle decompensation / overcompensation. This process has been described in many body organs and functions: muscle, stock energy, hormones, etc. It is a key driver of growth.
Thus, it was shown that the well-trained marathoner had stronger bones than sedentary. Indeed, its more dense bone structure, higher in fiber and calcium. In addition, the microscopic architecture of the bone is perfectly oriented along the axis of mechanical stresses.
Indeed, the chemical structure of the bone is comparable to reinforced concrete. The protein network is the steel rods. Calcium is comparable to concrete mired these metal axes. At the hip and pelvis direction of the bone structure is very characteristic. On a radiograph, it is found that the fibers leave the femur, the thigh bone, tilt in, come from hip to withstand the weight of the body resting on the hips. The lines of force from the right leg and left leg meet in the middle of the basin and support each other in the manner of the nave of a church.
Physical activity associated with a sufficiently high protein diet, vitamin D and calcium is a great engine of bone construction. This cocktail is particularly useful to hinge periods of life. During growth, it is necessary to eat 4-5 dairy products every day to build strong bones. It should also move: it is essential to practice a sport requiring the running and jumping at least 3 times a week for 30 minutes. In the absence of impact, bones harden less. It has been shown that a young competitive swimmer had lower bone density than sedentary because he was deprived of gravity during those long hours of pool training. In addition, bone densification stops 25 years. At this age you have made up your bone capital for life!
In adulthood, sport reinforces very hard bone and the amount of calcium necessary for the maintenance of bone is still debated. In case of fracture, the rest of the broken area needed a few weeks to allow to "ensnare" the broken area. In addition, gradually increasing mechanical stress are indispensable to "mechanize" the callus. Again, they help to guide the fabric of the bone in the center of the constraints to prepare him for his mission. An increase in calcium intake in consolidation period is proposed by some doctors without that interest has been really shown.
After menopause, the bone structure is gradually degraded to make the brittle bones is osteoporosis. Ladies, remember, your resistance to hip fracture depends on your diet and your sport for 25 years! If physical activity after menopause can no longer denser bones, reduces the loss of bone tissue. So it is advisable to go see jumping around or jog. It is also good to make the soft gym to maintain bone strength to strength. To make the most of this stimulation, it is again necessary to take 4-5 dairy products daily. It should also go out every day to enjoy the sun and make the vitamin D essential for the absorption and calcium binding. Fresh coordinating sports such as Thai Chi or "balance workshops" have proven effective in reducing the risk of falls and fractures.
If the sporting activity is excessive, the micro-cracks caused by impacts on the bones fail to consolidate over the rest. Rather, these lesions worsen in the next workout. Finally the splits right through bone, it breaks without any violent trauma. It is the stress fracture. In a postmenopausal woman, it was demonstrated that 6 hours of sport load per week may be sufficient to break insidiously bones. Among younger adults, this type of injury is favored by dietary deficiencies and hormonal disorders. Lack of calcium, vitamin D and protein alters the rebuild bone victim of microcracks in the exercise. Insufficiency sex hormones reduces the stimulation microscopic chemical plants be responsible for the synthesis of bone tissue. Functional changes occur when the deep depletion of the body. That kind of burnout is most often diagnosed in women because it causes menstrual irregularities and a cessation of menses. The victim is found in a state of "early menopause". In humans this hormone suffering is more insidious but it exists and its effects on bone density are comparable. The sports overwork cocktail, dietary deficiencies and disappearance of rules typically found in young women anorexic. Faced with a stress fracture, the sports physician must remain vigilant. It should not simply treat a "bone". It has an obligation to support a whole person, he is responsible for seeking overtraining or behavioral disorders.
