A Review Of Acetabular Prostheses For Total Hip Arthroplasty, Jennifer Anne Citarella
A Review Of Acetabular Prostheses For Total Hip Arthroplasty, Jennifer Anne Citarella
Theses
This study explores the evolution, design, and clinical progress of contemporary prostheses used in orthopaedic reconstruction of the socket of the hip joint. A literature search was performed to study acetabular implants, as used in total hip arthroplasty. The history of the design of these implants is chronicled. Next, the anatomy of the acetabular region and the surgical technique performed to replace the hip socket are presented. A comprehensive discussion of the design features, rationale, and clinical results for commercially available cemented and cementless prostheses follows.
Hydroxyapatite, a bioceramic which has just recently been approved for applications in total hip …

Posterior Stabilized Knee Design Biomechanical Considerations, Donald E. Mcnulty
Theses
Numerous posterior stabilized knee systems are available for primary and revision total knee arthroplasty. Design of these systems requires an understanding of the articulating geometries and kinematic/kinetic biomechanical considerations of the normal knee. The findings for the normal knee are integrated into the design of a prosthetic system.
The natural femoral, tibial and patella articulating geometries are defined to enable subsequent kinematic and kinetic analyses. The articulating geometries are characterized from review of anthropometric studies of the tibiofemoral and patellofemoral joint.
The kinematic analysis of the natural knee defines knee motion in terms of rotation, adduction/abduction, range of motion and …
