Abstract — This review is an attempt to untangle the complexity of transtibial prosthetic socket fit, determine the most important characteristic for a successful fitting, and perhaps find some indication of whether a particular prosthetic socket type might be best for a given situation. Further, it is intended to provide directions for future research. We followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and used medical subject headings and standard key words to search for articles in relevant databases. No restrictions were made on study design or type of outcome measure. From the obtained search results (n = 1,863), 35 articles were included. The relevant data were entered into a predefined data form that incorporated the Downs and Black risk of bias assessment checklist. Results for the qualitative outcomes (n = 19 articles) are synthesized. Total surface bearing sockets lead to greater activity levels and satisfaction in active persons with amputation, those with a traumatic cause of amputation, and younger persons with amputation than patellar tendon bearing sockets. Evidence on vacuum-assisted suction and hydrostatic sockets is inadequate, and further studies are much needed. To improve the scientific basis for prescription, comparison of and correlation between mechanical properties of interface material, socket designs, user characteristics, and outcome measures should be conducted and reported in future studies.

Key words: amputation, patellar tendon bearing socket, prosthesis, PTB socket, qualitative outcome, socket, total surface bearing socket, transtibial, TSB socket, vacuum-assisted suction socket, VAS socket.

In order to achieve a TSB socket with a silicone liner, the prosthetist in the reported study fabricated a soft inner socket by laminating a silicone resin over the positive plaster model of the residual limb.
A pin lock silicone liner with a distal stabilizing matrix, with or without a covering fabric. Stabilizing matrix is stated to minimize pistoning.
