“…PT length, width and thickness found in our work are located in a medial range to what was reported in eastern countries studies [11,20]. In the mentioned works, the PT presented a length between 36.0 mm-40.4 mm, with a PT width of 6.3 mm-10.1 mm and a thickness in a range of 2.4 mm-3.6 mm.…”

Background: The popliteus muscle fulfills a function of rotational stabilizer of the knee. Its particular shape and innervation pattern are the interest of anatomists and surgeons. The aim of this work was characterizing the anatomy and innervation of the popliteus muscle of knees from a sample of mestizo-raced population, predominant in Latin America. Methods: This cross-sectional study was made in 23 knee segments 14 right knees and 9 left knees coming from 14 men and 9 women aged 67 ± 22 years. Results: The popliteus muscle presented a scalene-like triangle shape and its medial base was covered by the superficial expansion of the semimembranosus tendon. The length of its base was 79,2±12,8 mm with a superior and inferior side that measured 58.0±7.4 mm and 101.7±11.7 mm respectively. The popliteus muscle innervation was supplied by the tibial nerve (TN) by the arising of two branches in 22 cases (95.7%). The first branch arose proximal to the inter articular line and presented a length of 91,1 mm. The second branch arose distally to the inter articular line with a length of 48.4±1.3mm. The third was observed in just one case (4.3%) Its length was 108±1.1mm and it arose distally to the inter articular line. Conclusions: The morphological characteristics of the popliteus muscle and its innervation patterns found in our study differ from what was reported in previous studies. The presence of these findings can be considered during the planning of surgical procedures in the posterior aspect of the knee.

“…Despite its clinical significance, injuries of PLC could be still undiagnosed, and left untreated clinically due to its complex structuring and variations in anatomy Covey, 2001& Zeng et al, 2011. The lack of reconstruction of the PLC structures causes the failures of surgery and residual instability of the knee (James et al;Covey;Jung et al, 2010& Djian, 2015.…”

SUMMARY:To reveal the detailed morphological features of the fibular collateral (fibular) ligament, popliteus tendon, popliteofibular ligament and the synovial components regarding to achieve data for surgical and biomechanical utilization. Knees of 10 formalin-fixed male cadavers were dissected bilaterally. Bursae around the lateral collateral ligament and the relation of popliteus tendon with lateral collateral ligament at the femoral attachment site were noted. The positional relation between both ends of popliteofibular ligament was evaluated statistically. The PT exceeded the anterior margin of lateral collateral ligament in 11 sides, the posterior margin of lateral collateral ligament in 3 sides and exceeded both the anterior and posterior margins of lateral collateral ligament in 5 sides. The shape of lateral collateral ligament was narrower at the lower part than the upper in 14 sides. The width of lower part of lateral collateral ligament was found narrower in the cases with sheath-like bursa (vagina synovialis). The relation between both ends of popliteofibular ligament was as followed: the more anteriorly the fibular head attachment was located, the more anteriorly popliteofibular ligament was attached to the popliteus tendon. To resolve the posterolateral corner of the knee with regard to surgical anatomy and biomechanics, individual and concerted morphometric characteristics of lateral collateral ligament, popliteus tendon and PF should be evaluated together with accompanied synovial structures.

“…Despite the fact that the PFL is believed to be a constant or rarely absent structure, it is crucial that physicians are aware of its anatomical variations and know the limitations of US evaluation. The different appearances of the PFL were described in the cadaveric study by Zeng et al [ 28 ]; they reported that, although the PFL was constantly present in their specimens, in 12.3% of cases, it was thinner and fascia-like. We hypothesize that in such individuals the visualization of the PFL could be challenging or even impossible via US.…”

The popliteofibular ligament: a cadaveric ultrasound study

et al. 2021

Objective The popliteofibular ligament (PFL) is an important stabilizer of the knee found within the posterolateral corner (PLC) of the joint. Injuries to the PLC can cause substantial patient morbidity. Accurate PFL visualization has been historically challenging, impeding injury diagnosis and treatment. The gold standard for in vivo PFL visualization is magnetic resonance imaging (MRI), but this procedure has slice thickness limitations, is costly, and is subject to longer wait times. Ultrasonographic (US) PFL assessment is a potentially viable alternative to MRI. This study aimed to determine the viability of US PFL assessment. Materials and methods Ten fresh-frozen lower limb specimens were evaluated for the presence and morphometric characteristics of the PFL via US using an 18.0-MHz linear transducer. The cadavers were then dissected and reassessed for the presence and morphometric characteristics of the PFLs for comparison with US findings. Moreover, the fracture of the fibular styloid process near the site of the insertion of the PFL (the arcuate sign) was simulated and assessed via US. Results The PFL was visualized and measured in all ten knees via both US and cadaveric assessments. There were no statistically significant differences in PFL morphometric characteristics determined via US examination and dissection. The fibular styloid fracture was easily identified in US examination. Conclusion US imaging is a viable alternative for accurate and effective assessment of the normal PFL. Moreover, the arcuate sign can be evaluated via US.
