摘      要：Background The incidence of total hip replacement in the younger and more active patients is ever *** ceramic-on-ceramic （COC） bearing was developed to reduce wear debris-induced osteolysis and loosening and to improve the longevity of hip *** studies have reported the clinical results and complications of the new zirconia-toughened ceramic total hip arthroplasty （THA）.Methods A consecutive series of 132 young patients （177 hips） that underwent primary cementless THAs between January 2010 and December 2012 were included in this *** arthroplasties all had fourth-generation COC bearings performed through a posterolateral *** average age was （41.8±8.3） years （ranging from 22 to 55 years）,and the mean follow-up period was （24.5±9.4） months （ranging from 12 to 47 months）.The results were evaluated both clinically and *** hip score （HHS） was determined before surgery and at the time of each *** of postoperative groin or thigh pain and squeaking were *** complications such as dislocations,periprosthetic fractures,and ceramic components fractures were diagnosed and treated in *** The average HHSs improved from preoperative 60.3±10.7 （ranging from 29 to 76） to 91.0±5.1 （ranging from 74 to 100） at the final follow-up （t=-45.064,P 0.05）,and 97.7％ of cases were scored as excellent and good *** the last follow-up,incidental inguinal pain was found in three hips （1.7％） and thigh pain in 11 hips （6.2％）.Radiographs showed a high rate of new bone formation around the acetabular and stem *** obvious osteolysis or prosthesis loosening was *** occurred in six hips （3.4％）：posterior dislocation in two hips （1.1％）,periprosthetic femoral fracture in one hip （0.6％）,asymptomatic squeaking in two hips （1.1％）,and ceramic liner fracture in one hip （0.6％）.Conclusions The fourth-generation COC THA showed excellent clinical results in younger active patients w
