![]() Medi-Rehatek will continue to introduce classification of below-knee prosthesis. According to suspension mode of socket,calf prosthesis with patellar ligament bearing load is divided into PTB (patellar-tendon-bearing),PTES (prosthese-tibiale-emboitage-supracondylienne),KBM( kondylen-bettung-Munster). ⑴PTB (patellar-tendon-bearing) calf prosthesis - has a patellar ring belt on patellar belt as major part of bearing load,is suitable for patients with mid-calf amputation. ⑵PTES (prosthese-tibiale-emboitage-supracondylienne) prosthesis is a calf prosthesis with patellar ligament bearing load and knee containment.The anteriorpart of socket extends to the upper edge of the patella and wraps around the patella.Both sides of the socket also extends to the upper edge of outside and insidefemoral condyle. This kind of calf prosthesis has a good function of suspension , can be used for amputees with shorter stump. ![]() ⑶ KBM (kondylen-bettung-MOnster) calf prosthesis - is a wedge-shaped calf prosthesis with patellar ligament bearing load, the anterior part of the prosthetic socket is attached to the lower edge of the patella, both sides have the wing-like prominence, extend to the upper edge of outside and inside femoral condyle. ![]() The interior part is provided with a detachable wedge-shaped plate conforming to the shape of the femoral condyle. When the residual limb penetrates into the socket,then the wedge plate is inserted in, and the suspension and fixation functions well. This calf prosthesis only uses different suspension from PTES, its appearance isslightly better than PTES, also applies to amputees with shorter stump.
