Total hip arthroplasty for patients with failed internal fixation of acetabular fractures / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To observe the clinical result and healing of meniscal suture under arthroscopy for the treatment of the middle aged patients with meniscal injury.</p><p><b>METHODS</b>From March 2014 to January 2015, 40 middle-aged patients included in the standard with injury of meniscus, which were repaired by meniscal suture technique under arthroscopy, involving 24 males and 16 females with an average age of (52.65±3.63) years ranging from 50 to 60 years; 28 cases were on left knee, 12 cases were on right knee. Average flexion angle averaged (117.50±7.16) ° ranging from 110° to 130°. Lysholm knee score averaged 54.30±14.72 ranging from 23 to 71; IKDC score averaged 50.65±15.95 ranging from 18 to 78; the WOMAC score averaged 23.80±19.39 ranging from 2 to 75. All-inside meniscus suture under arthroscopy was performed.</p><p><b>RESULTS</b>All operations were successful without serious complications. Postoperative follow-up was 6 to 12 months, none of the patients lost to follow-up. All patients maintain a category 5 degree muscle strength, normal knee joint mobility, can completely straight and completely buckling. Average flexion angle was (125.00±5.13) ° (110° to 130°) (=3.47,=0.003). Final Lysholm scale, IKDC scores and WOMAC scores averaged 79.50±8.70 (=7.790,=0.000), 79.40±10.40 (=8.431,=0.000), 8.15±6.77 (=3.988,=0.001) separately. Follow-up MRI showed that meniscus healed in 4 cases, partially healed in 22 cases, haven't healed in 14 cases. Failure rate of small lesion was 27.3%(6/22), and failure rate of large lesion was 44.4%(8/18).</p><p><b>CONCLUSIONS</b>Clinical effect of meniscal suture under arthroscopy for the treatment of the middle aged is good. The failing rate was 35% because of healing ability is poor in middle-aged adults. Failure rate of large lesion was higher than that of small lesion.</p>
