AK TURNTABLE
AK turntable in the prosthetic field is a rotational adapter used in above-knee (AK) prostheses. It is usually positioned between the prosthetic socket and the knee unit. The main function of the turntable is to allow rotation of the prosthetic limb around its vertical axis, which helps reduce torsional forces transmitted to the residual limb. The turntable may be free-rotating, friction-controlled, or lockable, depending on the user’s needs. It is especially useful during activities such as turning, sitting, standing up, or getting in and out of a vehicle, where twisting movements occur. By allowing controlled rotation, the AK turntable improves comfort, reduces shear stress on the stump, and helps prevent skin irritation or breakdown.
