Summary
Total knee replacement (TKR) success relies on implant stability. This review examines condylar constrained knee (CCK) and rotating hinge (RH) implants for primary and revision TKR, noting literature gaps.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Total knee replacement (TKR) is increasingly performed for osteoarthritis, leading to more revision surgeries.
- Long-term TKR success depends on component stability and bone fixation.
Purpose of the Study:
- To review literature on condylar constrained knee (CCK) and rotating hinge (RH) implants in primary and revision total knee replacement.
- To focus on the indications and outcomes of these constrained implants.
Main Methods:
- Literature review of studies on CCK and RH implants in TKR.
- Analysis of indications, results, and limitations reported in existing studies.
Main Results:
- Excellent and very good results have been reported for CCK and RH implants.
- Literature limitations include unclear indications, lack of long-term data, and few comparative studies.
Conclusions:
- Constrained implants like CCK and RH show promise in TKR, but further research is needed.
- More robust studies are required to define optimal indications and long-term efficacy.
