“…However, this study did not evaluate gaps or patients' clinical outcomes [19]. In a cadaver study, Tantavisut et al reported that complete PT resection in Posterior-Stabilized (PS) TKA led to an increase both flexion and extension gaps [16]. However, Ghosh et al reported that isolated PT injury does not lead to abnormal laxity in PS TKA [4].…”

“…Tantavisut et al researched gap changes after popliteus tendon resection in TKA with 14 fresh cadavers. Using a digital vernier caliper for measurement, they reported that the mean distance between the most distal femoral attachment of the PT and the most distal lateral condyle was 8.9 mm (range 6.4-10.5 mm), and that the distance from the most posterior femoral attachment of the PT to the posterior lateral femoral condyle was 11.5 mm (range 9.5-14.0 mm) [16]. In the present study, the area of the PT was smaller and the area of the LCL was similar compared with previous anatomical studies.…”

Background: The popliteus tendon (PT) or lateral collateral ligament (LCL) stabilizes the postero-lateral aspects of the knees. When surgeons perform total knee arthroplasty (TKA), PT and LCL iatrogenic injuries are a risk because the femoral attachments are relatively close to the femoral bone resection area. The purpose of this study was to evaluate the distance between the PT or LCL footprint and the TKA implant using a 3D template system and to evaluate any significant differences according to the implant model. Methods: Eighteen non-paired formalin fixed cadaveric lower limbs were used (average age: 80.3). Whole length lower limbs were resected from the pelvis. All the surrounding soft tissue except the PT, knee ligaments and meniscus were removed from the limb. Careful dissection of the PT and LCL was performed, and the femoral footprints were detected. Each footprint periphery was marked with a 1.5 mm K-wire. Computed tomography (CT) scanning of the whole lower limb was then performed. The CT data was analyzed with a 3D template system. This simulation models for TKA were the Journey II BCS and the Persona PS. The area of each footprint, and the length between the most distal and posterior point of the lateral femoral condyle and the edge of each footprint were measured. Matching the implant model to the CT image of the femur, the shortest length between each footprint and the bone resection area were calculated.

“…Takahashi et al reported that average distance from the PT to the distal articular surface and the posterior articular surface was 10.2 mm (range 6.5 to 16.2mm), 15.1mm (range 11.7 to 19.0mm) respectively [16]. Tantavisut et al reported that the mean distance between the most distal femoral attachment of the PT and the most distal lateral condyle was 8.9mm (range 6.4 -10.5mm), and the distance from the most posterior femoral attachment of the PT to the posterior lateral femoral condyle was 11.5mm (range 9.5 -14.0mm) [19]. Compared with previous anatomical studies, the measured area and placement of PT or LCL femoral footprint in this study was similar.…”

“…Several reports have been evaluated the PT or LCL injury in the surgical procedure of TKA. Simone et al showed that iatrogenic PT injury during total knee arthroplasty results in decreased knee function two to three years [1,5,8,11,16,19,20].…”

Background When the surgeons perform total knee arthroplasty (TKA), PT and LCL iatrogenic injury are worried because those femoral footprints are relatively close to the bone resection lesion. The purpose of this study was to evaluate the distance between PT or LCL footprint and TKA implant using the three-dimensional (3D) template system.Methods Eighteen non-paired formalin fixed cadaveric lower limbs were used. All the surrounded soft tissue except the PT and knee ligaments were removed from the limb. Careful dissection of the PT and LCL was performed, and those femoral footprints were detected. Each footprint was periphery marked with a K-wire. CT scanning of the whole lower limb was then performed. The CT data was analyzed with 3D template system. Simulated models of TKA were Journey II BCS and Persona PS. The area of each footprint, and the length between most distal or posterior point of femur and the edge of each footprint were measured. When the implant model was matched to the CT image, the shortest length between each footprint and the bone resection were evaluated.Results The area of PT and LCL footprint were, 38.7±17.7mm 2 , and 58±24.6mm 2 , respectively. The length between most distal or posterior point of femur and the edge of the PT footprint were 10.3±2.4mm, and 14.2±2.8mm, respectively. The length between most distal or posterior point of femur and the edge of the LCL footprint were 16.3±2.3mm, and 15.5±3.3mm, respectively. When simulated the TKA, the shortest length between PT footprint and bone resection lesion of Journey II BCS and Persona PS were, 4.3±2.5mm, and 3.2±2.9mm, respectively. The shortest length between PT footprint and bone resection lesion of Journey II BCS and Persona PS were, 7.2±2.3mm, and 5.6±2.1mm, respectively. PT footprint was suffered by the bone resection of Journey II BCS TKA in 3 knees, and also by the Persona PS’s bone resection in 9 knees.Conclusion The PT and LCL femoral footprint existed close to the femoral bone resection lesion of the TKA. Careful attention is needed not to injure the PT and LCL in the surgical procedures.
