“…They concluded that the dimensions of many total knee prostheses, at that time, difered from the actual knee morphology observed. As such, it was suggested that manufacturers more appropriately determine suitable sizing and aspect ratios in future TKA designs [13,15]. Likewise, the present study's investigators observed a > 2:1 ratio in overhang observed in the AP plane compared to the ML plane with the modern TKA system used in this study.…”

Purpose Surgeons must rely on manufacturers to provide an appropriate distribution of total knee arthroplasty (TKA) sizes. There is a lack of literature regarding current appropriateness of tibial sizing schemes according to sex. As such, a study was devised assessing the adequacy of of-the-shelf tibial component size availability according to sex. Methods A search was conducted to identify all primary TKAs between July 2012 and June 2019 performed using a single implant. Baseline patient characteristics were collected (age, weight, height, BMI, and race). Two cohorts were created according to patient sex. Tibial sizes for each cohort were collected. Tibial component bar graph and histogram were created according to component sizes. Skewness and kurtosis were calculated for each distribution. Overhang was noted and measured radiographically. Results A total of 864 patients were identiied, 38.7% males and 61.3% females. Most patients were Caucasian, and BMI was similar between cohorts. Tibial size distribution for males was as follows: 0.3% C, 4.8% D, 16.5% E, 40.1% F, 31.4% G, 6.9% H. Tibial size distribution for females was as follows: 30.8% C, 42.8% D, 23.0% E, 2.6% F, 0.8% G, 0.0% H. Histograms and normal curves demonstrated a fairly symmetric distribution of sizes for males (skewness = − 0.31, kurtosis = − 0.03). The distribution for females was positively skewed (skewness = 0.57, kurtosis = 0.12). Overall, overhang was noted in 16.6% of all size C tibias. Conclusions The results of this study highlight an implant-speciic discrepancy in size availability afecting female patients which could result in inferior outcomes. The authors urge manufacturers to critically assess current implant size distribution availability to ensure both genders are adequately, and equally represented. Level of evidence IV.

Introduction: Knee joint is modified complex synovial joint perform wide range of three dimension movement. Arthritis of knee joint joint needs intervention as total knee arthroplasty and unicompartment knee arthroplasty commonly. This study provide useful data for those surgeries. In present study collected data on the morphometry of both tibiofemoral articulation play a unique role in conduction of body weight. Morphometry of tibial plateau is used to guide treatment and monitor outcome of total knee replacement. Measurements of tibia plateau are of immense help in designing tibial prosthesis. Aim: My study was aimed at analyzing Three different parameters of tibia were measured and their mean values were determined. Materials and Methods: In the present study,a total thirty, adult fully ossified dry tibia, unknown sex and without any deformity were collected from Department of Anatomy of Kanti Devi Medical College ,Mathura for evaluation .Took various parameter of superior end by using a Vernier caliper and rular. Result & Conclusion: The TTT area is greater in the right tibia when compared with the left tibia. The mean area of MTC of the right tibia is greater than the area of MTC of the left tibia, whereas the mean area of LTC of the right tibia is smaller than the area of LTC of the left tibia. This study will be useful for anatomist, forensic anthropologist and orthopedics in cases total knee arthroplasty, unicompartment knee arthroplasty and meniscal transplantation.
