Long-term follow-up results of some artificial hip and knee joints 1. Trabecular Metal C It has been 15 years since the first prosthesis was implanted in 1997! The revision rate of trabecular metal cups at 8-10 years follow-up was 0 (George et al); no osteolysis was detected at an average of 10.3 years (9.6-10.8 years) follow-up (Todd et al). 2. Longevity-Highly Crosslinked Polyethylene Longevity Highly Crosslinked Polyethylene has been in use for 12 years since 1999. 10-year follow-up of Longevity showed little detectable wear and no periprosthetic osteolysis on radiographs (Harris et al). 3. Fiber Metal Mesh Material – Titanium Fiber Metal Material Titanium Fiber Metal Material has been in clinical use for over 25 years and has been shown to have good bone ingrowth and enhanced retention through bone tissue endogenesis. From the original Harris/Galante and HGP-II to today’s Trilogy, Trilogy AB, and Trilogy IT, this titanium fiber material has been used. 95.7% survival rate at 15-year follow-up (Parvizi et al); 100% survival rate at an average of 11-year follow-up (4-25 years) (Robert et al). (Robert et al). 4. Allofit acetabular cup Since the first implantation in 1993, the uniquely designed Allofit acetabular cup is another acetabular cup prosthesis with proven long-term follow-up in addition to the trabecular metal cup and titanium wire acetabular cup. The survival rate at 11.9 years of follow-up was 97.5% ( Zenz et al). The Wagner SL revision femoral stem, designed by Prof. HeinzWagner in 1987, was a milestone in the field of hip revision and a truly revolutionary design, and the Wagner SL revision femoral stem is considered the most successful biologically based one-piece revision system worldwide in the last 20 years. The survival rate at 15.8 years of follow-up was 96.6% ( Regis et al). The Swedish National Register (1979C2000 ) has the lowest 8-year revision rate for the shank. 5. CLS femoral stalk Since its invention by Prof. Lorenzo Spotorno in 1984, the CLS femoral stalk has been one of the most successful implants recorded in Swedish National Artificial Hip Arthroplasty. Its clinically documented results remain unmatched. The Swedish National Registry has recorded a 100 percent survival rate for CLS at 10 years, 99 percent at 13 years and 97.6 percent at 17 years. Also in 2010 the UK National Health Service awarded CLS a 10A femoral stem rating, the highest rating possible in the UK at this time. 6. CPT Femoral Shank A cemented shank with excellent clinical results. the first implant was completed in 1990. The collarless, highly polished design results in a very high survival rate of 98.9% at 15 years ( Burston et al). 7. NexGen LPS knee John N. Insall, considered the father of the modern artificial knee, began designing the NexGen LPS knee system in the mid-1990s and went on to develop the NexGen knee system. both the LPS and LPS-Flex have a 10-year survival rate of 100% (defined by aseptic loosening, Young- Hoo Kim et al). Medical data from the Swedish Knee Replacement Registry 2008 10 years from 1997-2006. NexGen has the lowest revision rate and the lowest relative risk of revision of any manufacturer! While the medical literature is important, the actual clinical statistics are even more convincing. 8. NexGen Mobile Knee The NexGen Mobile Knee, a rotating platform that more closely resembles human dynamics and has excellent clinical results, was first implanted in 1999. Survival rate of 99.1% at 10.6 years (defined by aseptic loosening, Jean-Noel et al). 9. The unicondylar Zimmer Unicompartmental Knee ZUK is based on a design concept that has proven successful, i.e., based on more than 10 years of excellent clinical success with the M/G unicondylar knee, with a 10-year survival rate of more than 95%, allowing patients to safely achieve 155° hyperflexion ( Argenson JN et al; Berger RA et al; Donald et al).
