Purpose

The success rate of surgical debridement and prostheses retention for acute periprosthetic joint infection (PJI) is controversial. This study aims to report our experience in managing acute PJI following total knee arthroplasty (TKA) with surgical debridement and prostheses retention, and to identify the prognostic factors that may influence the surgical outcomes.

Methods

A retrospective review from our prospective joint replacement register in Queen Mary Hospital, Hong Kong, of patients who were managed with surgical debridement and prosthesis retention for acute PJI after TKA between 1998 and 2013 was performed. The diagnosis of acute PJI was based on the 2011 Musculoskeletal Infection Society (MSIS) PJI diagnostic criteria. Both the early post-operative infections and the late haematogenous infections were included (Tsukayama type 2 and 3). Surgical outcomes were defined as successful if patients’ clinical symptoms had been relieved; inflammatory marker levels including C-Reactive Protein (CRP), Erythrocyte Sedimentation Rate (ESR) and White Blood Cell (WBC) count had returned to normal; X-rays showed no prosthetic loosening; and no lifelong antibiotic suppression was required. Outcomes were defined as failed if patients required any further surgeries (e.g., re-debridement, one or two-stage revision), or needed lifelong antibiotic suppression. All Patients’ perioperative data, i.e., age, primary diagnosis, pre-operative CRP, ESR, WBC, haemoglobin, albumin, glucose level, time lag from symptoms onset to debridement, synovial fluid total cell count and bacteriology were traced and recorded. SPSS 22.0 was used to calculate and compare the statistical differences between surgically successful group and failed group regarding the factors above.

Objective

Failures of internal fixation after intertrochanteric fractures pose great challenge to orthopaedic surgeons. Hip arthroplasty can be a remedy for such failures, however, the selection of femoral stem length is controversial. This study aims to report our experience of managing failed internal fixation after intertrochanteric fractures with standard femoral stem arthroplasty.

Methods

A retrospective review of patients who were managed with hip arthroplasty for failed internal fixation after intertrochanteric fractures in the First Affiliated Hospital of Fujian Medical University, P.R. China between January 2001 to December 2013 was performed. Patients’ age, gender, pre- and postoperative Harris Hip Score (HHS), femoral stem types and surgical outcomes were traced and analyzed.
