Upto 20 0 of flexion can be accomodated. Many knee units do not have a device to increase stability. Found inside – Page 689A supracondylar-suprapatellar suspension system encloses the patella in the socket and has a bar proximal to the patella. This design also provides mediolateral stability, and no additional cuffs or straps are required. Supracondylar This is a variation of the supracondylar-suprapatellar suspension and is used generally with patients who have longer residual limbs and who can better control the prosthesis in the anterior plane. The supracondylar suspension, although adequate, is not without drawbacks; mainly, lack of suspension during high degrees of knee flexion. 4 TheScientificWorldJournal Table2:Comparisonbetweenthethreeliners. Knee locks in extension for heel strike and foot flat. The most popular is the constant friction unit, which has a clamp that can vary the friction easily. 5/6/18 Found inside – Page 632FIGURE 23-12 Another option for donning supracondylar or supracondylar/suprapatellar sockets is removal of the ... the medial wing in place, to achieve the proximal purchase over the femoral condyles used to suspend the prosthesis. - 가볍다.

The surgeon suspends the knee by attaching an implant on both sides of the knee joint (one side attached outside and below and one inside). Supracondylar-suprapatellar suspension. 4. It limits the load on the pressure sensitive areas such as the distolateral end of the femur, pubic symphysis, and perineal area.

This design also provides mediolateral stability, and no additional cuffs or straps are required. ... Suprapatellar Suspension. The prosthetic knee is aligned posterior to a line extending from the trochanter to the ankle assisting in maintaining knee extension.
