Synopsis: This meta-analysis identified 12 randomized trials that compared patient-specific instrumentation (PSI) and standard instrumentation in patients undergoing total knee arthroplasty (TKA). Results indicated but no significant difference for outliers in hip-knee-ankle (HKA) alignment, outliers in tibial coronal alignment, or operative time. Meta-analysis of coronal Read More »
Author verified Level 2 Meta Analysis
Synopsis: 7 randomized control trials (RCTs) and 11 non-randomized control trials (nRCTs) assessing differences between patient-specific instrumentation (PSI) and conventional instrumentation (CONV), in terms of incidences of component misalignment in primary total knee arthroplasty (TKA), were included in this study. Results determined that the occurrence of outliers - defined as those with alignment 3° from the desired position - was similar between the two groups. No significant difference Read More »
Level 2 Meta Analysis
Synopsis: Fourteen studies (7 randomized controlled trials and 7 non-randomized controlled trials) were included in this meta-analysis and systematic review examining the use of patient specific instrumentation in total knee arthroplasty. Studies were selected if they compared outcomes - including the incidence of outliers (>3 degree deviation from planned alignment), operative time, blood loss, and length of hospital stay - between surgery completed with PSI versus conventional instrumentation. Meta-analysis demonstrated no Read More »
Level 2 Meta Analysis
Synopsis: 140 patients scheduled for total knee arthroplasty were randomized to have the procedure completed using either patient specific instrumentation or conventional intramedullary instrumentation. The purpose of this study was to compare radiological, clinical, and perioperative data between groups. The primary outcome Read More »
Level 2 RCT
Synopsis: Seven randomized controlled trials were included in this meta-analysis investigating the efficacy of patient-specific instrumentation (PSI) in total knee arthroplasty compared to conventional instrumentation. Data was pooled on mean deviation from neutral mechanical alignment, as well as the incidence of outliers from neutral mechanical alignment (>3dg deviation). Pooled results demonstrated Read More »
Author verified Level 2 Meta Analysis
Synopsis: 112 adults with advanced osteoarthritis who were scheduled to undergo primary uncemented total knee arthroplasty (TKA) were randomly allocated to computed tomography (CT)-based patient-specific instrumentation (PSI) or conventional instrumentation. Radiographic evaluation was performed 12 months postoperatively, and findings revealed no statistically significant differences in coronal or sagittal implant positioning between techniques, except in the frontal tibial component angle (FTC). Patients in the Read More »
Level 2 RCT
Synopsis: 90 patients diagnosed with primary osteoarthritis were randomly assigned to undergo total knee arthroplasty using either conventional instrumentation, MRI-based patient-specific instrumentation, or CT-based patient-specific instrumentation. Patients were assessed after surgery for coronal alignment (mechanical axis, femoral component, and tibial component), sagittal alignment (posterior slope), and axial alignment (rotation of the femoral component|). Clinical scores were Read More »
Level 2 RCT
Synopsis: 9 publications comparing standard instrumentation with patient-specific instrumentation for total knee arthroplasty were included in this review and meta-analysis. This study aimed to compare both sets of instrumentation in terms of coronal and sagittal alignment, operative time, intraoperative blood loss, and cost. Findings reported patient-specific Read More »
Level 2 Meta Analysis
Synopsis: 40 patients suffering from severe knee arthritis were randomized to undergo unilateral primary total knee arthroplasty using either patient-specific or conventional instrumentation, with the purpose of comparing gait and functional outcomes between treatment groups. Results revealed patient-specific Read More »
Level 2 RCT
Synopsis: Data from 8 RCTs and 8 cohort studies were pooled to investigate the effect of patient-specific instruments (PSI) on radiological outcomes after total knee replacement (TKR). The pooled analyses examined the following outcomes; mechanical axis alignment and malalignment of the femoral and tibial components in the coronal, sagittal and axial planes, as well as relative risks (RR) for malalignment of all studies and for RCTs and cohort studies separately. Results indicated that Read More »
Level 2 Meta Analysis
Synopsis: Six randomized controlled trials were included in the meta-analysis, the purpose of which was to evaluate the clinical and radiographic outcomes of gender-specific prostheses to standard unisex prostheses in female patients undergoing total knee arthroplasty. Pooled data showed Read More »
Level 1 Meta Analysis
Synopsis: 36 patients undergoing total hip arthroplasty were randomized to undergo acetabular component placement using either patient-specific instrumentation (PSI) or standard mechanical guides. The purpose was to evaluate whether the use of PSIs resulted in more accurate positioning of the acetabular cup with respect to preoperative planned angles of anteversion and abduction. CT assessment postoperatively Read More »
