“…According to Matsuno et al14, in patients with serious medial compartment degenerative arthritis of the knee, after wearing the off-loading knee brace for 12 months, the decrease of pain, the decrease of the angle between the femur and tibia, and the increase of the isokinetic muscular strength of the quadriceps muscle of thigh were observed. According to Dennis et al12, in patients that expereinced major medial compartment degenerative arthritis of the knee, walking on a treadmill before and after wearing the off-loading knee brace was analyzed with fluoroscopy, where the group reported the decrease of pain and the widening of the distance between the medial compartment of the knee joints after using the brace. In addition, Pollo et al15 confirmed that after using the off-loading knee brace, the pain decreased and the intensity of activity increased, and as the valgus moment functioning in the outside of knee joints grew larger, the load to the medial compartment of knee joints decreased.…”

“…However, many studies with on patients with unilateral degenerative arthritis of the knee report decrease of pain, increase of muscular strength and improvement in daily living activities after using the off-loading knee brace 12-15. In addition, the effects of the external moment of the brace that increase the weight load to the affected leg during the stance phase by reducing the pain of knee joints at the time of walking, and increase the speed of walking by reducing the imbalance of the step length with the non-affected leg, were reported 16.…”

ObjectiveTo provide the off-loading knee brace was designed relief for the pain associated with osteoarthritis by reduce loads on the degenerative compartment of the knee. This study examined the effects of the off-loading knee brace on activation of femoral muscles during squatting, slow and fast walking exercise in healthy young individuals.MethodTen healthy male subjects without a history of knee pain were recruited. Each subject was asked to do squatting, slow and fast walking exercises with a brace secured to the dominant leg. The same exercises were repeated without the brace. Surface electromyographic (sEMG) data was collected from the vastus medialis oblique (VMO), vastus lateralis (VL) and biceps femoris (BF) muscles from the dominant side of the leg. All dynamic root mean squre (RMS) values of sEMG were standardized to static RMS values of the maximal isometric contraction and expressed as a percentage of maximal activity.ResultsWe found that VMO activity was significantly decreased with application of the off-loading knee brace during squatting and fast walking exercise. However there were no significant differences in VMO activity with application of the off-loading knee brace during slow walking exercise.ConclusionThese results suggest that the external moment of the brace which effectively stabilized the patella in the movement in which the knee joints become relatively unstable. The brace could be useful in the short term, but for long-term use, weakening of the VMO is predicted. Therefore the program of selective muscular strength strengthening for the VMO should be emphasized.

Une orthèse crurosurale prolongée d'une coque talonnière ou une orthèse cruropédieuse permettent de mettre en décharge un compartiment fémorotibial arthrosique. Pour garantir l'efficacité de l'appareillage, il faut réunir plusieurs conditions : un certain degré de mobilité frontale, un moulage en contrainte, une orthèse rigide dans le plan frontal, des appuis bien placés et confortables. Mots clés Gonarthrose · Orthèse · Moulage en contrainteAbstract Unloading of an arthritic tibiofemoral compartment of the knee joint may be effected by a knee brace extended by a heel cup, or by a long leg brace terminating beyond the ankle joint. Several conditions must be satisfied to ensure effectiveness of the appliance. These include a certain degree of anterior mobility, moulding of the brace with the joint under stress, rigidity of the brace in the anterior aspect and well-placed and comfortable supports.

“…Dennis et al [9] konnten im Rahmen ei ner fluoroskopischen Untersuchung an 45 Probanden mit medialseitiger Gon arthrose nachweisen, dass bei korrekt eingestellter Orthese fluoroskopisch eine Separation des medialen Femurkondylus vom Tibiaplateau von durchschnittlich 1,7 mm festgestellt werden konnte, was in einer Kontrollgruppe nicht nachweisbar war. Positiv im Hinblick auf die Reduk tion arthrosebedingter Beschwerden be werteten dann auch 85% der Patienten in der Therapiegruppe die Orthese.…”

Technical orthopedic fittings play an important role for conservative treatment to help patients with severe osteoarthritis. For the knees these include braces, orthoses and shoe fittings such as dampers, lengthening of the medial or lateral sole and a large number of walking aids. All these aids are able to decrease pain, improve life quality and are therefore a good treatment option, although the progression of the disease itself cannot be altered.
