ENGLISH ABSTRACT: Patient-specific canine knee implants have the potential to restore lost mobility to knees experiencing joint degradation. Due to high costs associated with current implant solutions, this research focused on creating and implementing an open-source design approach for a non-cruciate-ligament-sparing total knee replacement. Femoral and tibial canine knee implant components were generated for three different canine specimens. Open-chain knee joint kinematics and kinetics were studied using an Oxford-type test rig and a 3D motion tracking system. Pre- and post-implant knee joint results were obtained for flexion-extension, internal-external rotation, adduction-abduction, mediolateral shift, anterior-posterior drawer, joint compression-distraction and quadriceps forces during joint extension. The open-source design approach was implemented for three different cases, with encouraging results being achieved for the total knee replacement implants compared to the kinematic and kinetic performance of healthy canine knees. AFRIKAANSE OPSOMMING: Pasiëntspesefieke honde-knievervangings het die potensiaal om verlore mobiliteit te herstel in knieë wat gewrigsdegradasie ondergaan. Weens die hoë koste wat met huidige knie vervangingsoplossings gepaard gaan, het hierdie navorsing gefokus op die skepping en implementering van ‘n ontwerpsbenadering wat van vrylik beskikbare bronne gebruik maak om ‘n nie-kruisligament-sparende totale knievervanging te skep. Femorale en tibiale hondeknie vervangingskomponente was gegenereer vir drie verskillende honde-beenmonsters. Oop-ketting lit kinematika en kinetika was bestudeer met die gebruik van ‘n Oxford-tipe toetstuig en ‘n 3D-bewegingsopsporing sisteem. Voor- en na-knievervanging resultate was verkry vir fleksie-uitbreiding, interne-eksterne rotasie, adduksie-wegtrekking, mediale-laterale verskuiwing, anterior-agterste verskuiwing, litkompressie-spanning en quadricep-spierkragte tydens lituitbreiding. Die vrylik-beskikbare-bron-ontwerpsbenadering was geïmplementeer vir drie verskillende gevalle, waarvoor belowende resultate bereik is nadat die totale knievervangings met kinematiese en kinetiese verrigting van gesonde hondeknieë vergelyk is.
