Comprehensive assessment of patellar morphology using computed tomography-based three-dimensional computer models

摘要: Abstract Background The objectives of this study were to assess patellar morphology using computed tomography-based three-dimensional computer models and determine the utility subchondral method for resection in total knee arthroplasty (TKA). Methods Overall, 120 subjects (60 males, 60 females) from 20 50 years old included. Computer tomography images used construct 3D 240 knees. An anthropometric analysis variance was with detect differences between sides, age groups, genders. Results Based on available numbers, there significant gender length, width, thickness even strict control height weight patients. average width/thickness ratio 1.95, regardless gender, a good correlation width (male: r = 0.68, p  Conclusions A robust measuring virtually resecting patella established. dimensions could provide basic data guiding surgical management TKA are useful designing implants. Clinical relevance information is essential surgeons perform resurfacing TKA.
