Background. Total knee arthroplasty (TKA) is the highly developed procedure for sever osteoarthritic knee, in which there are two major concepts; Cruciate Retaining design (CR) and Posterior Stabilized design (PS). The femoral roll back movement is enforced with the post-cam mechanism in the PS, however, this structure associates with the complications, i.e. wear and dislocation. The CR has been developed to obtain the knee stability with native posterior cruciate ligament (PCL) in TKA. However, the preservation of the PCL can limit
No predictive model has been published to forecast operating time for total knee arthroplasty (TKA). The aims of this study were to design and validate a predictive model to estimate operating time for robotic-assisted TKA based on demographic data, and evaluate the added predictive power of CT scan-based predictors and their impact on the accuracy of the predictive model. A retrospective study was conducted on 1,061 TKAs performed from January 2016 to December 2019 with an image-based robotic-assisted system. Demographic data included age, sex, height, and weight. The femoral and tibial mechanical axis and the osteophyte volume were calculated from CT scans. These inputs were used to develop a predictive model aimed to predict operating time based on demographic data only, and demographic and 3D patient anatomy data.Aims
Methods
Treatment outcomes for methicillin-resistant Total knee arthroplasty (TKA), MRSA inoculation, debridement, and vancomycin-spacer implantation were performed successively in rats to mimic first-stage PJI during the two-stage revision arthroplasty procedure. Vancomycin was administered intraperitoneally or intra-articularly for two weeks to control the infection after debridement and spacer implantation.Aims
Methods
Our aim was to evaluate the functional outcome of extensile revision
The aim of the study was to investigate rotational behaviour of the arthritic knee before (preimplant) and after (postimplant) total knee replacement (TKR) using (image-free navigation system as a measurement tool which recorded the axial plane alignment between femur and tibia, in addition to the coronal and sagittal alignment as the knee is flexed through the range of motion. The data on the rotation of the arthritic knee was collected after the
Between the year 1987 to 2005, 45 primary knee replacements were performed for 30 patients affecting ankylosing knee joint. 23 patients were having flexion fused deformities with 38 knee arthroplasty, ten of them were having flexion fused deformities over than 60 degrees. 18 cases were performed ipslateral THR &
TKR. 2 AS patients undergone THR, TKR and total ankle replacement on the same anesthesia. The other 7 patients were having extension ankylosing deformities with 9 primary TKR performed. All patients were post infection deformities with the exception of one Rheumatoid Arthritis and one hemophiliac patient with bilateral extension ankylosing deformities of the
Aims: Prospective randomized single blind investigation was made to evaluate inßuence of two surgical approaches to the knee (antero-medial approach and subvastus approach) for total knee arthroplasty. Materials: Between 1995– 2002 215 consecutive total knee arthroplasties in 204 patients (192 women, 12 men) were made. There are following prosthesis implanted: PFC Ð 74, GSB Ð 45, PFC ∑ Ð 73, Link Ð 5, AGC Ð 18. All patients were evaluated. Patientsñ mean age was 65,7 years old. TKR with antero-medial approach was performed in 98 cases (45 per cent), whereas TKR with subvastus approach was performed in 117 cases (55 per cent). Methods: Functional status according to HSS scale at the 14 days and 6 months after procedure was regard as end results for both protocols. Results: In group with antero-medial approach there were: 26,4% excellent results, 69,8% good results and 3,8% fair results respectively. In group with subvastus approach there were: 24,3% excellent results, 70,2% good results, 3,3% fair and 2,2% poor results respectively. There are no statistical differences between early functional results of these two surgical approaches for total knee replacement. Conclusions: We assumed that subvastus approach is as good as anteromedial one in
