Abstract
The TPP is a bone conserving Total Hip Replacement (THR). Originally designed in 1977, two modifications have been made since then and in its current form has been available since 1981.
We have used the TPP with a metal-on-metal articulation for active “younger” patients. The acetabular component has been the Armor cup.
48 TPPs have been performed in 41 patients since 1995. The age of the patients was 48 (21–54) years at the time of the operation. There were 17 females and 24 male patients. All patients are kept on an annual review. At the last review, one patient (2 THR) had died at eight weeks from a pulmonary embolism; one patient was lost to follow-up; one patient had required a revision for aseptic loosening.
We believe that this THR may offer a viable alternative for the younger patient, though it is a technically demanding procedure.
