Above-knee (transfemoral) prosthesis

A complete limb system for transfemoral amputees, combining an intimate-fit socket, a mechanical or microprocessor knee and a dynamic foot for a safe, energy-efficient gait.

Above-knee (transfemoral) prosthesis

Indications

  • Unilateral or bilateral transfemoral amputation
  • Hip-region femoral amputation
  • Short residual limb needing a specialised socket
  • Elderly patients and growing children

Key features

  • Ischial-containment / MAS socket from 3D scan
  • Knee options: polycentric, locking, hydraulic or microprocessor
  • Negative-pressure vacuum suspension
  • Energy-returning carbon fibre foot
  • Dynamic alignment on a gait-analysis rig

Transfemoral amputees must compensate for the loss of both the knee and the ankle, so socket design is decisive. We capture the residual limb with a 3D scan and fabricate an ischial-containment / MAS socket that hugs the pelvis, distributes load evenly and stays stable through stance.

A negative-pressure vacuum suspension with a one-way valve creates total-surface contact with the residual limb, reducing pistoning, improving circulation and restoring a sense of limb position. Patients stand and walk over uneven ground with more confidence.

Depending on the mobility grade (K1–K4) we match the knee joint: a locking knee for early training, a polycentric or hydraulic knee for indoor and outdoor walking, and a microprocessor knee for stairs, slopes and variable speed. An energy-returning carbon foot keeps each step light.

Completion includes static alignment, dynamic alignment on a gait-analysis rig and training sessions with a prosthetist. We review the fit periodically to adjust the socket as limb volume changes and to service the mechanical components.
