A significantly lower percentage of patients had traumatic reinjuries in the
patellar group (four patients compared with 16 for hamstring tendon and 17 for double-bundle grafts; P = 0.010); however, there was a higher percentage of kneeling pain in the
patellar group (10 percent of patients compared with 4 percent for hamstring tendon and 2 percent for double-bundle grafts; P = 0.029).
With this in mind, we hypothesized that the methylation status of the MMP11 promoter might differ in DNA isolated from
patellar tendinopathy compared to normal tendon.
Osteochondral fracture may occur at the time of
patellar dislocation or reduction and usually follows the impact between the medial facet of the patella [Figure 1]a and the lateral facet of the lateral femoral condyle [Figure 1]b.
Patellar tendon stiffness was assessed using myotonometric measurements obtained with the Myoton Pro device (Myoton AS, Tallin, Estonia).
Department of Orthopaedics, RG Kar Medical College and 25 (15 males and 10 females) mean age patients were included in the study, who had history of recurrent
patellar dislocation as per inclusion and exclusion criteria.
Patellar maltracking measurements (trochlear depth, the trochlear sulcus angle (TSA),
patellar translation, the lateral patellofemoral angle (PFA) and the Insall-Salvati ratio) were performed on the entire knee MRI scans of the study and control groups.
The measurements were performed at the University Clinic for Orthopedic Surgery in Skopje, with knee flexion at 30 and 60 degrees, in order to measure the bony and cartilaginous SA on the
patellar surface of the femur (Figure 1).
quadriceps femoris tendon and the
patellar ligament in Rh.
Fundamental to designing a new, noninvasive instrument for
patellar resection is determining suitable contact points on the front (anterior) surface.
Strong contraction of the quadriceps femoris muscle during leg extension causes failure of the physis at the
patellar tendon insertion [5].
All patients (n = 6), who have undergone a surgical resection of a soft tissue sarcoma affecting the quadriceps tendon, the patella, and/or the
patellar tendon without apparent joint involvement were included in this study.
