Abstract:

BACKGROUND: Although cementation of polyethylene liner into a well-fixed metal shell during the revision surgery has several advantages compared to total acetabular revision, there are some disputes about its clinical outcomes, especially regarding the re-revision rate and the prosthetic survivorship.
OBJECTIVE: To evaluate the clinical outcomes and safety of cementation of polyethylene liner into a well-fixed acetabular cup in the revision after total hip arthroplasty with retained stable cup.
METHODS: Between March 2012 and November 2014, nine patients underwent revision after total hip arthroplasty with cementation of polyethylene liner into a well-fixed acetabular cup. There were 1 male and 8 females, aged 43.7 years on average. The time was 9.4 years on average from the primary total hip arthroplasty to revision. Harris Hip Score and prosthesis X-ray films were compared after revision. The effects and safety of cementation of polyethylene liner into a well-fixed acetabular cup were further evaluated. 
RESULTS AND CONCLUSION: Nine patients were followed up for 8-37 months. The Harris hip scores before revision was (49.54±18.28) points previously, and (84.82±10.59) points during final follow-up (t=6.377, P < 0.05). One patient had re-revision surgery because of recurrent dislocation. There were not complications in other patients, resulting in failure rate of 11%. These results indicated that polyethylene liner cementation technique is safe and effective when the well-positioned and well-fixed acetabular cup retained.
