TI  - Comparison of Iatrogenic Soft Tissue Trauma in Robotic-Assisted versus Manual 
      Partial Knee Arthroplasty.

AB  - Partial knee arthroplasty (PKA) is performed to treat end-stage osteoarthritis in 
      a single compartment. There are minimal data characterizing soft-tissue injuries 
      for PKA with robotic and manual techniques. This cadaver study compared the 
      extent of soft-tissue trauma sustained through robotic-arm assisted PKA (RPKA) 
      and manual PKA (MPKA). Five surgeons prepared 24 cadaveric knees for medial PKA, 
      including six MPKA controls and 18 RPKA assigned into three different workflows: 
      RPKA-LB (six knees) - RPKA with legacy burr; RPKA-NB (six knees) - RPKA with new 
      burr design; and RPKA-NBS (six knees) - RPKA with new burr design and oscillating 
      saw. Two surgeons estimated trauma to the patellar tendon, quadriceps tendon, 
      anterior cruciate ligament (ACL), medial collateral ligament (MCL), medial 
      capsule, posterior capsule, and posterior cruciate ligament (PCLs) using a 
      five-grade system: Grade 1 - complete soft tissue preservation; Grade 2 - </=25%; 
      Grade 3 - 26 to 50%; Grade 4 - 51 to 75%; and Grade 5 - >/=76% trauma. A total 
      trauma grade was assigned by summing the grades. Kruskal-Wallis statistical tests 
      were used to assess outcomes. When compared to the MPKA group, all RPKA subgroups 
      had lower total trauma grading (p<0.01), lower posterior capsular damage 
      (p<0.01), and less severe ACL damage (p<0.01). The analysis demonstrated no 
      significant difference between the three RPKA workflows. As this study was 
      performed using cadaveric specimens, additional investigations are necessary to 
      determine associations between robotic or manual-assisted technique, observed 
      soft tissue damage, and postoperative clinical outcomes following PKA.
