Abstract(s)

In the last decade considerable modifications in the surgical procedures recommended for the treatment of rheumatoid knee have been observed. This was due to all the medical developments achieved in pharmacology and therapeutic as well as a significant quality improvement of the rheumatologist s intervention. The synovectomy and namely the total knee arthroplasty represent the most commonly procedures used in the surgical treatment of the rheumatoid knee. An arthroscopic followed by a radionuclide synovectomy can be an appropriate treatment in a knee with an inflammatory arthritis Larsen radiograph grade I II . The ideal patient for synovectomy must present an early disease absence of deformity or instability good range of motion and preserved articular cartilage. On the other hand a total knee arthroplasty represents the only possible operation to treat a rheumatoid knee with a severe bone and cartilage damage Larsen radiograph grade IV V including younger patients.Total knee arthroplasty is actually a successful operation providing pain relief and the restoration of the function. Nevertheless the excellent good short and medium-term results achieved do not resist over time. Similarly to what happens with every other arthoplasty joint replacements the particules that come from the wear of the biomaterials included in its composition are the cause of biological intolerance reactions which can lead to the need of a new implant. The replacement prosthesis raises technical issues related to the reconstruction of bone mass losses where the cryopreserved bone allografts can be recommended.
