    Arthroscopic fixation with intra-articular button for tibial intercondylar eminence fractures in skeletally immature patients
    (Lippincott Williams & Wilkins, 2016) Memişoğlu, Kaya; Müezzinoğlu, Ümit Sefa; Atmaca, Halil; Sarman, Hakan; Kesemenli, Cumhur Cevdet
    The aim of this study was to describe our experiences with arthroscopy-guided intra-articular button fixation in the treatment of displaced tibial eminence fractures in skeletally immature children. Eleven adolescent patients with an average age of 12.2 years were treated arthroscopically between January 2005 and February 2007. At follow-up evaluation at 69 months, we did not find any instability. Only minimal differences were found in the functional outcomes (Lysholm and International Knee Documentation Committee scores: 95.7 and 94.3, respectively). None of the patients had a leg-length discrepancy defined at the time of the final follow-up. The advantages of this technique are as follows: (a) it is a simple and reliable arthroscopic technique with a direct view, (b) the fixation is stable, (c) there is no need to remove the implant, (d) minimal physeal interruption in a pediatric skeletally immature population, and (e) no additional arthroscopic portal.

    A new isometric quadriceps-strengthening exercise using EMG-biofeedback
    (E-Century Publishing Corp, 2014) Kesemenli, Cumhur Cevdet; Sarman, Hakan; Baran, Tuncay; Memişoğlu, Kaya; Binbir, Ismail; Işık, Cengiz; Boyraz, İsmail; Koç, Bünyamin
    A new isometric contraction quadriceps-strengthening exercise was developed to restore the quadriceps strength lost after knee surgery more rapidly. This study evaluated the results of this new method. Patients were taught to perform the isometric quadriceps-strengthening exercise in the unaffected knee in the supine position, and then they performed it in the affected knee. First, patients were taught the classical isometric quadriceps-strengthening exercise, and then they were taught our new alternative method: "pull the patella superiorly tightly and hold the leg in the same position for 10 seconds". Afterward, the quadriceps contraction was evaluated using a non-invasive Myomed 932 EMG-biofeedback device (Enraf-Nonius, The Netherlands) with gel-containing 48 mm electrodes (Turklab, The Turkey) placed on both knees. The isometric quadriceps-strengthening exercise performed using our new method had stronger contraction than the classical method (P < 0.01). The new method involving pulling the patella superiorly appears to be a better choice, which can be applied easily, leading to better patient compliance and greater quadriceps force after arthroscopic and other knee surgeries.
