Abstract:
Objective To review the clinical results of cemented and uncemented revision total hip arthroplasty(RTHA). Methods The diagnoses included aseptic loosening of the femoral components in 23 cases, fractures around the tip of loosened femoral components in 3 cases. Of 26 cases, 10 cases(10 hips)underwent RTHA by the use of the second generation cementing techniques, 16 cases(16 hips)underwent uncemented RTHA with a long stem porous coated femoral component assisted with autografting. Results At an average of 6 years of follow- up for cemented RTHA, clinical results were evaluated as excellent or good in 5 hips(50％ ),fair in 3 hips(30％ ) and poor in 2 hips(20％ ), re- revision in 1 hip(10％ ). X－ ray film revealed definite loosening in 2 hips, probable loosening 1 hip, possible loosening 5 hips, and no loosening 2 hips. At an average of 5 years follow- up for uncemented RTHA,clinical results were evaluated as excellent in 9 cases(56％ ),good in 6 cases(38％ ), fair in 1 case (6％ ),no case need rerevision. X－ ray film revealed osseous fixation of the femoral components in 12 cases (75％ ), fibrous stability in 4 cases (25％ ). The apparent reconstitution of femoral bone structure present in the area of previous osteolysis or cortical thinning. Conclusion Clinical results of the uncemented RTHA are significantly superior to that of cemented RTHA. Reconstructing any structural bone loss with cancellous autograft and getting adequate mechanical fixation with a long stem porous- coated prosthesis may contribute to the good results of uncemented RTHA.
