OBJECTIVE To establish if harvesting cartilage to source chondrocytes for autologous chondrocyte implantation (ACI) results in donor site morbidity. DESIGN Twenty-three patients underwent ACI for chondral defects of either the ankle or the hip. This involved cartilage harvest from the knee (stage I), chondrocyte expansion in the laboratory and implantation surgery (stage II) into the affected...

PURPOSE To compare the medium-term outcome of revision total knee arthroplasty (TKA) for septic versus aseptic failure. METHODS Records of 142 patients who underwent revision TKA by a single senior surgeon for septic (n=65) or aseptic (n=77) failure were reviewed. In the septic group, 67 knees in 42 women and 23 men were included. In the aseptic group, 88 knees in 51 women and 26 men were inc...

PURPOSE We compared and analyzed the short term results of high flexion total knee arthroplasty (TKA) with mobile-bearing and fixed bearing designs. MATERIALS AND METHODS We studied 32 patients that had undergone TKA with LPS-Flex Mobile and 34 patients with LPS-Flex Fixed using an electromagnetic navigation system between January 2010 and June 2010, and were followed up for at least 1 year. ...

Between 1980 and 1995, 95 consecutive total knee replacements were performed at an average of 10 years 4 months after high tibial osteotomy. The average age of the 82 patients was 66 years, with a preoperative diagnosis of osteoarthritis in 94 knees. One patient died 6 months after surgery. The followup of the remaining 81 patients (94 knees) averaged 8.6 years (range, 2-17 years). Knee Society...

OBJECTIVE The purpose of this study was to compare the clinical outcomes between patients with a valgus or varus deformity undergoing minimally invasive total knee arthroplasty through the medial approach. METHODS The patients were classified into 2 groups according to the preoperative femorotibial angle measured on an anteroposterior long leg roentgenogram. The valgus group comprised of 26 k...

A series of 100 consecutive osteoarthritic patients was randomised to undergo total knee replacement using a Miller-Galante II prosthesis, with or without a cemented polyethylene patellar component. Knee function was evaluated using the American Knee Society score, Western Ontario and McMaster University Osteoarthritis index, specific patellofemoral-related questions and radiographic evaluation...

PURPOSE To review clinical results of total knee arthroplasty (TKA) in rheumatoid arthritis (RA) patients with large bone defects of the tibial condyle. METHODS Records of 33 knees in 27 women and 3 men aged 44 to 80 (mean, 63.6) years who underwent primary TKA for RA with large tibial bone defects were reviewed. 16 knees had peripheral defects extending to the bone cortex, whereas 17 knees h...

OBJECTIVE The aim of this study was to compare the responsiveness of various patient-reported outcome measures (PROMs) and clinician-reported outcomes following total knee arthroplasty (TKA) over a 2-year period. METHODS Data were collected in a prospective cohort study of primary TKA. Patients who had completed Forgotten Joint Score-12 (FJS-12), Western Ontario and McMaster Universities (WOM...
