The management of bone loss in revision total knee replacement.
The management of bone loss in revision replacement of the knee remains a challenge despite an array of options available to the surgeon. Bone loss may occur as a result of the original disease, the design of the prosthesis, the mechanism of failure or technical error at initial surgery. The aim of revision surgery is to relieve pain and improve function while addressing the mechanism of failur...
متن کاملComputational study on the effect of malalignment of the tibial component on the biomechanics of total knee arthroplasty
OBJECTIVES Malalignment of the tibial component could influence the long-term survival of a total knee arthroplasty (TKA). The object of this study was to investigate the biomechanical effect of varus and valgus malalignment on the tibial component under stance-phase gait cycle loading conditions. METHODS Validated finite element models for varus and valgus malalignment by 3° and 5° were deve...
متن کاملThe influence of stem length and fixation on initial femoral component stability in revision total knee replacement
OBJECTIVES Orthopaedic surgeons use stems in revision knee surgery to obtain stability when metaphyseal bone is missing. No consensus exists regarding stem size or method of fixation. This in vitro study investigated the influence of stem length and method of fixation on the pattern and level of relative motion at the bone-implant interface at a range of functional flexion angles. METHODS A c...
متن کاملTibial component rotation in total knee arthroplasty
BACKGROUND Both the range of motion (ROM) technique and the tibial tubercle landmark (TTL) technique are frequently used to align the tibial component into proper rotational position during total knee arthroplasty (TKA). The aim of the study was to assess the intra-operative differences in tibial rotation position during computer-navigated primary TKA using either the TTL or ROM techniques. The...
متن کامل[Total knee replacement following high tibial osteotomy].
PURPOSE OF THE STUDY The objective of the study was to find out to what extent anatomical changes due to high osteotomy of the tibia affect knee function after total knee arthroplasty. MATERIAL Of the patients with knee osteoarthritis treated by cemented total PFC prostheses in 1995, two groups were selected. Group I consisted of 50 patients who had knee replacement without previous tibial os...
