Summary
Total knee replacement offers improved long-term outcomes compared to hip replacement. Modern prostheses like the Kinemax are effective for various patient groups, including the active and those with complex knee conditions.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
Background:
- Total knee replacement (TKR) has advanced significantly.
- Long-term TKR outcomes now surpass those of total hip replacement.
- Late 1980s designs focused on improving function, mobility, wear, and survival for active individuals.
Purpose of the Study:
- To highlight the success of conventional, cemented knee arthroplasty.
- To present the Kinemax total knee replacement prosthesis as a state-of-the-art option.
- To discuss the versatility of the Kinemax design in treating complex knee conditions.
Main Methods:
- Review of long-term outcomes for total knee replacement.
- Evaluation of prosthesis designs from the late 1980s.
- Assessment of the Kinemax prosthesis capabilities.
Main Results:
- Total knee replacement demonstrates superior long-term results compared to total hip replacement.
- The Kinemax prosthesis represents advanced design addressing function, mobility, wear, and survival.
- The Kinemax design is suitable for standard TKR and complex cases.
Conclusions:
- Conventional, cemented knee arthroplasty, exemplified by the Kinemax prosthesis, is highly successful.
- The Kinemax design offers a versatile solution for a wide range of patients, including those with postseptic knees, bone defects, and specific lifestyle considerations.
