“…To our knowledge, there is only one published study investigating the changes in femoral cartilage thickness in individuals with flatfoot. Similar to our study, Öztürk et al 24 reported that femoral cartilage thickness at the intercondylar area and the medial condyle were higher in individuals with flatfoot, but both groups had similar femoral cartilage thickness at the lateral condyle. In this study, the increase in femoral cartilage thickness in individuals with flatfoot was associated with changes in lower extremity alignments with flatfoot.…”

“…Similar to previous studies, 29,34 the patellar tendon thickness was performed at the inferior pole of the patella and 1 cm proximal of the inferior pole of the patella (Figure 1B). Similar to previous studies, 15,24 the femoral cartilage thickness was measured with the participants in the supine position with the knee in maximum flexion. For the measurements of the femoral cartilage thickness, the transducer was placed axially above the patellar outer edge.…”

“…Murley et al 20 reported a decrease in Achilles tendon and peroneus longus tendon thickness in adults with flatfoot, and Gonul et al 10 indicated children with flatfoot had a thinner Achilles tendon. Furthermore, Öztürk et al 24 reported an increase in femoral cartilage at the intercondylar area and medial condyle. To our knowledge, there exists no study investigating potential differences in patellar tendon morphology in individuals with flatfoot.…”

Background: Changes in lower extremity alignment in individuals with flatfoot may be associated with differences in morphology of the tendons or cartilage in lower extremities. The purpose of the present study was to investigate the potential association of flatfoot with the morphology of the Achilles tendon, patellar tendon, and femoral cartilage. Methods: This study was conducted with 40 participants with flatfoot (28 females, 12 males) and 40 participants with a normal foot posture (28 females, 12 males). The thickness of the Achilles tendon (at points 2 and 3 cm proximal to the superior aspect of the calcaneus), patellar tendon (at the inferior pole of the patella and 1 cm proximal of the inferior pole of the patella), and femoral cartilage (at the intercondylar area, medial condyle, and lateral condyle) was measured by an ultrasonography device. Results: The Achilles tendon thickness at 2 cm ( P = .009) and 3 cm ( P = .010) proximal of the superior aspect of the calcaneus was on average 4% to 6% lower in individuals with flatfoot compared with controls. The cartilage thickness at the intercondylar area ( P = .005) and medial condyle ( P = .018) was on average 8% to 12% greater in individuals with flatfoot; however, the cartilage thickness at the lateral condyle and patellar tendon thickness was similar in both groups. Conclusion: The results obtained suggest that foot posture is associated with the morphology of the Achilles tendon and femoral cartilage. Level of Evidence: Level III, diagnostic comparative study.

“…The CT values from SPV-based measurements in the young asymptomatic participants in this study were similar to those reported in previous studies. 18,22 A significantly lower interrater ICC at the intercondylar groove from SPV-based measurements may indicate the challenge of using this view in patients with symptomatic KOA. As the concavity (or sharpness) of the femoral trochlea increased in the posterior aspect (more caudal), the varying angles of knee flexion in the patient group may have affected the measurements between the raters.…”

Objectives To examine the reliability and face validity of ultrasound (US) measurements of distal femoral cartilage thickness (CT) using the infrapatellar view (IPV) with knee extension compared to the traditional suprapatellar view (SPV) with knee hyperflexion in young asymptomatic participants and patients with painful knee osteoarthritis (KOA). Methods The IPV was obtained in an extended knee position by placing the US transducer on the patellar tendon at a 60° angle tilted toward the distal femoral condyle in 19 young adults (control group) and 70 patients with KOA. The CT was measured at the medial femoral condyle, the intercondylar notch, and the lateral femoral condyle. Results The inter‐rater intraclass correlation coefficient was higher for IPV‐based CT measurement (range, 0.856–0.858) compared to SPV‐based CT measurement (range, 0.315–0.523) among the patients with symptomatic KOA. The IPV‐based CT differed significantly between the control group and the KOA group at the intercondylar notch (P < .001) and lateral femoral condyle (P = .006). The SPV‐based CT differed significantly between the control group and the KOA group only at the lateral femoral condyle region (P = .014). Conclusions An infrapatellar US evaluation of the distal femoral CT can be a reliable alternative method to a suprapatellar US evaluation for patients with KOA.

“…These controversies include the validity and measurement technique for this test. Nevertheless, it has been reported in the literature that US can assess cartilage thickness accurately [7‐13]. Naredo et al [14] also reported that US demonstrated good reproducibility in the measurement of normal to damaged cartilage, although the positioning of the transducer while measuring femoral cartilage thickness has been a matter of debate.…”

Ultrasonographic Assessment of the Femoral Cartilage Thickness in Patients with Pes Planus

Abstract: The distal femoral cartilages of the pes planus patients seem to be thicker, and this finding could possibly stem from excessive mechanical stress on the knee joint caused by impaired lower extremity biomechanics.
