Below-knee (transtibial) prosthesis
For amputees who retain the knee, focused on a total-contact socket, a silicone liner and an activity-matched foot to restore gait quickly.
Indications
- Transtibial amputation from trauma, vascular disease or diabetes
- Ankle disarticulation (Syme)
- Congenital tibial deficiency
- Need for a spare or sports prosthesis
Key features
- Total-contact PTB / TSB socket
- Pressure-relieving silicone or gel liner
- Pin-lock, vacuum or supracondylar suspension
- SACH, single-axis, multi-axis or carbon foot
- Waterproof and running options available
Because the knee is preserved, transtibial amputees usually recover gait quickly and spend far less energy than transfemoral users. The key is a total-contact socket that loads pressure-tolerant areas and relieves sensitive ones.
A silicone or gel liner encloses the residual limb to cushion it, reduce shear and stabilise volume. Suspension can be a locking pin, a vacuum valve or a supracondylar grip depending on limb length and activity level.
The foot is chosen by goal: SACH and single-axis for slower indoor walking; multi-axis for rough ground; an energy-returning carbon foot for active users; and dedicated modules for swimming or running.
We finish with dynamic alignment and residual-limb skin-care coaching. Limb volume keeps changing for the first 6–12 months, so patients return for sock management or a replacement socket when needed.
