The OGS knees are thought to have stronger muscle power. The aim ofthis study is to evaluate muscle strength in OGS knees.Materials and methods:We examined 96 athletes who applied to our clinic. We evaluated the muscularstrength by separating the knees in two groups as the knees with OGS andwithout OGS. Knee muscle strength was measured in 60 and 180degrees/second with isokinetic dynamometer CYBEX NORM (CSMI Humac Norm, ABD).Peak torque (PT), peak torque/body weight (PT/BW) and agonist/antagonist(flexor/extensor, AG/AN) values were collected. Independent samples t-test wasused for statistical evaluation.Results: At 60 degrees, wefound a significant difference between PTE, PTF, PT / BW E and PT / BWF(p=0.02,p=0.002).PTE, PDF, PT/ BWF werestatistically significant also at 180 degrees(p=0,00 ).Conclusion: Muscle strengths ofthe non-OGS group were statistically stronger than those of OGS group.Inorder to demonstrate better performance of the athletes with OGS, trainingplans should be conducted to increase their muscle strength. KW - Knee Extensors KW - Muscle Strength KW - Sports N2 - Amaç: Os good schlatter (OGS), büyüme döneminde sporcular için sık görülenbir durumdur. Etiyoloji halen belirsizdir. Traksiyon apofiziti şeklindetanımlanmaktadır. OGS dizlerde daha güçlü kas gücü olduğu düşünülmektedir.Çalışmamızın amacı; OGS olanlarda kas gücünü değerlendirmektir. Yöntem: Kliniğimize başvuran 96 sporcuyuinceledik. Dizleri OGS olan ve OGS olmayan dizler şeklinde iki gruba ayırarakkas kuvvetini değerlendirdik. Diz kasları 60 ve 180 derece / saniye izokinetik dinamometre CYBEX NORM (CSMI HumacNorm, ABD) ile ölçüldü. Tepe torku (PT), zirve torku / vücut ağırlığı (PT / BW), PT / BW E zirve torku / vücut ağırlığı ekstansiyon, PT / BW F zirve torku /vücut ağırlığı fleksiyon ve agonist / antagonist (fleksör / ekstansör, AG / AN)değerleri belirlendi. İstatistiksel değerlendirme için bağımsız örneklemt-testi kullanıldı.Bulgular: 60 derecede, PTE, PTF, PT / BW E ve PT / BWF arasında anlamlı bir fark bulduk (p = 0.02, p = 0.002). PTE, PDF, PT / BWF,180 derecede istatistiksel olarak anlamlıydı (p = 0,00). Sonuç: OGS olmayan gruptaki sporcuların kaskuvvetleri ,OGS grubuna göre istatistiksel olarak daha güçlü idi. OGS olansporcuların daha iyi performans sergilemeleri için, kas kuvvetlerini arttırmakyönelik antrenmanlar düzenlenmelidir. CR - 1.
