How to choose a suitable prosthetic leg knee prosthesis China
How to choose a suitable prosthetic leg knee prosthesis China? It mainly involves these aspects:
Choice of fixation method: At present, the prosthesis with bone cement fixation is the most widely used clinically, and this kind of prosthesis has obtained long-term and reliable follow-up results in clinical practice. The role of bone cement is not only to fix the prosthetic leg knee prosthesis China, so that the prosthetic leg knee prosthesis China obtains an initial stability, but also to strengthen the bearing strength of the bone bed. Sometimes specific antibiotics can be mixed into the bone cement for fixation.
Choice of Unicompartmental Prosthesis: Unicompartmental prosthesis is non-limiting prosthesis. The purpose of choosing a unicompartmental prosthesis is to preserve the tissue structure, bone mass, and motion function of the joint to the greatest extent for subsequent total knee arthroplasty. This type of prosthetic leg knee prosthesis China is mainly suitable for lesions of the medial or lateral compartment alone, and the proportion of unicompartmental replacement in clinical practice is relatively small, accounting for about 7% to 10% of cases.
The choice of total knee prosthesis: The mechanical limitation of the prosthetic leg knee prosthesis China ensures the stability of the prosthesis, but at the same time creates a contradiction with the range of motion of the joint. Generally speaking, a less restrictive prosthesis can achieve better joint motion function, and a more restrictive prosthesis is designed to provide additional stability of the prosthetic leg knee prosthesis China, but may cause excessive osteotomy and highly restrictive prosthesis. It may also lead to loosening of the prosthesis-bone interface.
