Skeletal Muscle Size, Quality And Function In Patients With Several Years After Total Hip Arthroplasty

Total hip arthroplasty has become a successful way of treating the painful and destroyed hip joint in the patient with rheumatoid arthritis( RA). Two hundred twenty(135 cemented and 85 noncemented) total hip arthroplasties we were performed in 180 patients with rheumatoid arthritis. The average age was 48,61 years and the average follow-up was 8,4 years. Clinical evaluation was based on a Harris hip score that showed significant improvement in pain and function preoperatively compared with pain and function at follow-up. There were two deep infections requiring removal of the prosthesis. Four cemented acetabular cups and one cemented femoral component were revised due to aseptic loosening. Three acetabular rings were revised due to aseptic loosening. The relatively inferior results of total hip arthroplasty among RA patients is due not only to fixation method, but also to the poorer bone quality and weakening musculature. The results in these patients suggest that cement less total hip arthroplasty might become a successful way of treating the destroyed hip joint in the patient with rheumatoid arthritis.

Abstract Background Hip involved secondary to ankylosis spondylitis (AS) had a huge influence on hip function. Cementless total hip arthroplasty (THA) can improve hip function. However, no previous study compared the outcomes of THA for AS patients with three different degrees of hip involvement. Methods The 195 hips were retrospectively analyzed and divided into non-ankylosed group (group A, 94 hips), fibrous ankylosed group (group B, 49 hips), and bony ankylosed group (group C, 52 hips). postoperative range of motion (ROM), harris hip scores (HHS), the short-form 12 health survey (SF-12), length of stay (LOS), cost, radiological assessments, and complications were compared. Results The follow-up time was (79.4 ± 29.5) months for group A, (80.6 ± 28.9) months for group B, and (79.1 ± 28.9) months for group C (P = 0.966). Group A had the best postoperative hip ROM (P < 0.001), while group A and B can realize better HHS than group C (P < 0.001). The three groups had similar SF-12 postoperatively. For group A, LOS and cost for unilateral procedure were the least than that for group B and C (P = 0.003 and P = 0.001). Similar radiological assessments were achieved for three groups. 1 hip in group A encountered delay union of wound. 1 hip in group C encountered delay union of wound and dislocation and another patient encountered femoral fracture intraoperatively. 12 hips (12.8%) in group A, 6 hips (12.2%) in group B, and 6 hips (11.5%) in group C encountered asymptomatic heterotopic ossification (P = 0.977). Conclusion For AS patients with hip involvement, THA can improve hip ROM and function. THA for the non-ankylosed hip can realize the better hip function and postoperative ROM than ankylosed hip.
