Knee prosthesis constraint & stability test rig

A six-degree-of-freedom rig for constraint and stability testing of total knee prostheses to ASTM F1223, built as an MSc thesis at Sharif University of Technology under Dr Mohammad Durali, advised by Dr Farzam Farahmand. Mechanical design, automation architecture, PLC programming and HMI development were all done in-house. The rig has been delivered and is in research use.

No comparable machine existed in Iran; commercial equivalents come from companies such as EndoLab (Germany) and AMTI (USA). The project was named the faculty's best technological thesis, took second place at the 24th Khwarizmi Youth Festival, and was selected at the 64th Alborz Elite Prize. The rig was later reconfigured to study bone–implant friction, leading to a paper in Scientific Reports.
