In 2010, the Lithuanian Association of Arhtroplasty was established and on January 1, 2011, initiated a national study of all reoperations after total knee (TKR) and total hip replacement (THR) in Lithuania. The aim of the study was to investigate the revision rates after TKR and THR at two years follow-up.
Lithuanian patients undergoing primary TKR and THR from January 1, 2011, to December 31, 2012, were included in the study. The patient, surgery and prosthetic implantation data were collected via internet database. For reoperations we recorded the reason and type of revision, primary implantation date. We analyzed implant survival rates using any revision as an endpoint on included primary procedures, performed until September 1, 2013.
The completeness of the register verified with state patients fund data reached 85% of all replacements. Out of 3823 primary TKR during the study period 25 revisions were performed with overall implant survival rate 99%. The main reason for knee revision was infections. During the inclusion period we registered 6072 primary THR and 149 revisions with overall implant survival rate 97%. Recurrent dislocation of prosthetic component was the main reason for hip revision. Significantly inferior survival results for femoral neck fracture patients were observed as compared with patients operated for osteoarthritis. Posterior approach as compared to others significantly affected inferior implant survival rates for femoral neck fracture patients.
The overall survival after total knee and hip replacements revealed a high treatment quality of this surgery in Lithuania.
2010年，立陶宛关节成形术协会成立，并于2011年1月1日启动了一项关于立陶宛全膝关节置换术（TKR）和全髋关节置换术（THR）后所有再次手术的全国性研究。该研究的目的是调查TKR和THR术后两年随访时的翻修率。
纳入2011年1月1日至2012年12月31日在立陶宛接受初次TKR和THR的患者。通过互联网数据库收集患者、手术及假体植入数据。对于再次手术，我们记录了翻修原因和类型、初次植入日期。我们以任何翻修为终点，对纳入的初次手术进行分析，直至2013年9月1日，分析植入物生存率。
经国家患者基金数据验证，登记的完整性达到所有置换手术的85%。在研究期间的3823例初次TKR中，进行了25次翻修，总体植入物生存率为99%。膝关节翻修的主要原因是感染。在纳入期间，我们记录了6072例初次THR和149次翻修，总体植入物生存率为97%。假体部件反复脱位是髋关节翻修的主要原因。与骨关节炎手术患者相比，股骨颈骨折患者的生存率明显较低。与其他入路相比，后路显著影响股骨颈骨折患者较低的植入物生存率。
全膝关节和髋关节置换术后的总体生存率显示，立陶宛该手术的治疗质量较高。
