Building Relationship Network for Machine Analysis from Wear Debris Measurements
Integration of system process information obtained through an image processing system with an evolving knowledge database to improve the accuracy and predictability of wear debris analysis is the main focus of the paper. The objective is to automate intelligently the analysis process of wear particle using classification via self-organizing maps. This is achieved using relationship measurements...
متن کاملBiological Response of Osteoblasts and Osteoprogenitors to Orthopaedic Wear Debris
Total joint replacements are one of the most commonly performed orthopaedic procedures worldwide, with over 700,000 surgeries performed annually in the US to treat arthritic conditions of the hip and knee. One of the major complications of total joint replacement is implant wear and osteolysis, a process that involves continuous shedding of micronand submicron-sized particles from implant compo...
متن کاملWear and Wear Debris Generated from Ceramic-on-Carbon Fibre Reinforced PEEK Hip Replacements
INTRODUCTION Concerns regarding UHMWPE wear particle induced osteolysis [1] have led to investigations of alternative bearing materials. Carbon-fibre reinforced poly-ether-ether-ketone (CFR-PEEK) has been shown in animal studies to have a similar biological activity to UHMWPE [2], whilst hip and knee configurations incorporating this polymer display reduced wear rates when compared with convent...
متن کاملOn the debris-level origins of adhesive wear.
Every contacting surface inevitably experiences wear. Predicting the exact amount of material loss due to wear relies on empirical data and cannot be obtained from any physical model. Here, we analyze and quantify wear at the most fundamental level, i.e., wear debris particles. Our simulations show that the asperity junction size dictates the debris volume, revealing the origins of the long-sta...
متن کاملWear debris pseudotumor following total knee arthroplasty: a case report
INTRODUCTION In patients who have undergone a total joint replacement, any mass occurring in or adjacent to the joint needs thorough investigation and a wear debris-induced cyst should be suspected. CASE PRESENTATION An 81-year-old man presented with a painful and enlarging mass at the popliteal fossa and calf of his right knee. He had had a total right knee replacement seven years previously...
