We report the effectiveness of revision of total
elbow replacement by re-cementing. Between 1982 and 2004, 53 elbows
in 52 patients were treated with re-cementing of a total elbow replacement
into part or all of the existing cement mantle or into the debrided
host-bone interface, without the use of structural bone augmentation
or a custom prosthesis. The original implant revision was still
The purpose of this study is to report our experience with revision of total elbow arthroplasty by
Biofilm-related infection is a major complication that occurs in orthopaedic surgery. Various treatments are available but efficacy to eradicate infections varies significantly. A systematic review was performed to evaluate therapeutic interventions combating biofilm-related infections on in vivo animal models. Literature research was performed on PubMed and Embase databases. Keywords used for search criteria were “bone AND biofilm”. Information on the species of the animal model, bacterial strain, evaluation of biofilm and bone infection, complications, key findings on observations, prevention, and treatment of biofilm were extracted.Aims

Background: A continuing controversy in total knee arthroplasty is the question whether the posterior cruciate ligament should be retained or substituted. This report reviews a series of total knee arthroplasties with a fixed bearing posterior cruciate ligament retaining implant (Nex Gen. ©. CR, Zimmer Inc., Warsaw, IN). Methods: Between May 1997 and April 2001 197 patients were provided with 218 primary implants. There were 142 females and 55 males with an average age of 71 years (range 53–88 years) and a BMI of 28,9 kg/m. 2. (range 19,1–41,2 kg/m. 2. ). The diagnosis was osteoarthritis in 212 patients, 3 cases of aseptic osteonecrosis, 1 fracture of the tibia plateau, 1 prior infection and 1 psoriatic arthritis. 84 knees had prior operations including high tibial osteotomies and menisectomies. The operations were performed by 11 surgeons, with more than 80% done by 5 surgeons. 162 (74%) femur components and 181 (83%) tibia components were cemented. Patella resurfacing was performed in 135 (62%) cases. We evaluated the results prospectively with a clinical inspection, radiographs (AP and lateral, longleg standing, patella sunrise view), and the use of the Knee Society Score, Quality-of-Life Short Form-36 and WOMAC rating score. 149 patients were examined at a mean follow up of 5,9 years (range 4,1–8,2 years). 29 were questioned on the telephone, 29 deceased, 7 revisions had to be performed and 4 (2%) were lost to follow up. Results: The range of motion improved from 101° to 115° (range 80°–140°). All knees had sufficient antero-posterior and mediolateral stability. The Knee society score improved from 35 to 83 (good result) and the function score improved from 52 to 76 (good result). Early complications included 12 haematoma, 10 wound healing problems, 5 early infections, 2 thrombosis and 1 non lethal pulmonary embolism. 7 revisions had to be performed: 3 late infections (2 one-stage revisions with synovectomy and exchange of polyethylene inlay, one two-stage revision with semi-constrained implant LCCK© Zimmer Inc.), 3 patella resurfacing due to anterior knee pain and 1
