Knee Prosthesis Constraint and Stability Test Apparatus

Six-DOF testing of total knee replacements per ASTM F1223 — the first apparatus of its kind in Iran.

Year 2021Medical equipmentAutomationASTM F1223

A six-degree-of-freedom apparatus for constraint and stability testing of total knee replacements per ASTM F1223 — my MSc thesis at Sharif University of Technology, supervised by Prof. Mohammad Durali with Prof. Farahmand as consulting advisor. The apparatus has been delivered and is used for research.

No comparable apparatus existed in Iran; commercial equivalents are built by companies such as EndoLab (Germany) and AMTI (USA). I later reconfigured the same rig for a bone–implant friction study, which led to a paper in Scientific Reports.

My role

Mechanical design, automation architecture, PLC programming and HMI development; later, reconfiguring the rig for friction testing.
