A below-knee prosthesis (transtibial prosthesis) is the type of prosthesis used for limb loss occurring between the knee joint and the ankle joint. Its application is planned in line with the physician's assessment and prescription and is custom-made according to each user's anatomical structure.
The Importance of Socket and Suspension
One of the key elements of below-knee prostheses is the fit of the socket to the residual limb. Accurate measurement of the socket is decisive for both comfort and safe use.
Another important element is suspension, that is, the way the prosthesis is held on the leg. Adequate suspension supports balance and control while walking. The suspension method may vary depending on the condition of the residual limb and the person's daily activity level; pin-lock socket systems and active vacuum socket systems are among the common suspension options.
Foot and Ankle Options
After the socket and suspension, another component that affects the function of the prosthesis is the foot-ankle unit. The choice is evaluated jointly by the physician and the practitioner according to the person's mobility level, body weight and daily habits.
Preparation and Rehabilitation
The transition to using a prosthesis is a process, and the preparation period is an important part of it. The following topics stand out during this period:
- Shaping of the residual limb and appropriate bandaging
- Physical therapy and exercise to support physical adaptation
- Referral to relevant specialists for psychological support when necessary
- Pre-prosthetic information and training
Regular follow-up and rehabilitation may support adaptation to the prosthesis and long-term comfort of use.
