İzole Menisküs Yırtıklarında Alt Ekstremite Q Açısının ve Rotasyonel Dizilimlerin Karşılaştırılması

Amaç: Bu çalışmanın amacı alt ekstremitenin rotasyonel diziliminin ve kuadriseps (Q) açısının izole menisküs yırtıklarıyla ilişkisini değerlendirmektir. Hastalar ve yöntem: Bu çalışma tek taraflı izole menisküs yırtıklı 30 hastanın 60 dizi (hepsi erkek; ortalama yaşı 35.3; dağılım:17-47 yaş) ile kontrol grubu olarak, 30 sağlıklı gönüllünün 60 dizini (hepsi erkek; ortalama yaşı 33.6; dağılım:24-46 yaş) içeriyordu. Hastaların tanıları manyetik rezonans görüntüleme (MRG) ve ardından yapılan artroskopik cerrahi ile konuldu. 30 dizden oluşan dört grup oluşturuldu. Grup 1 izole menisküs yırtıklı hastalar ve Grup 2 hastaların sağlam dizlerini kapsamaktayken; Grup 3 sağlıklı gönüllülerin hasta dizine karşılık gelen tarafı, Grup 4 ise sağlam taraf dizlerinden oluşturuldu. Tüm grupların alt ekstremiteleri bilgisayarlı tomoğrafi (BT) eşliğinde femoral anteversiyon ve tibial torsiyon dereceleri ile Q açıları ölçüldü. Bulgular: Dört grubun alt ekstremiteleri arasında rotasyonel dizilim farkı saptanmadı. Ayrıca, hastaların menisküs yırtık taraflı ve sağlam dizi arasında Q açısı yönünden bir fark görülmedi. Bu çalışmada hasta grubundaki Q açısını kontrol grubundan önemli derecede daha yüksek gözlemledik. Sonuç: Çalışmamızda izole menisküs yırtığı ile alt ekstremitenin rotasyonel dizilimi bakımından herhangi bir ilişki gösteremedik. Bu bulgu izole menisküs yırtığında, alt ekstremitenin rotasyonel deformitelerinin başlıca etken olamayacağını düşündürmektedir. Ancak, artmış Q açısı menisküs yırtıklarına eğilimi artırıcı bir etken olabilir.

A comparison of rotational alignment and Q angle of the lower limb in isolated meniscal tears

Objectives: The aim of this study was to evaluate the isolated meniscal tears and its relation with the rotational alignments and quadriceps angles (Q angles) of the lower limb. Patients and methods: This study included 60 knees of 30 patients with unilateral isolated meniscal tears (mean age 35.3; range 17 to 47 years) and 60 knees of 30 healthy men were examined (mean age, 33.6; range 24 to 46 years) as controls. We divided into four groups of 30 limbs each as follows. Group 1 included the patients with isolated meniscal tears, and Group 2 included the patients with the contralateral intact limb. However, Group 3 included the healthy controls with ipsilateral limb, and Group 4 included the healthy controls with contralateral limb. The lower extremity of all groups were imaged by computed tomography and femoral anteversion, tibial torsion, and Q angles were measured. Results: There was no statistical difference in the rotational alignments with the lower limb between the four groups. Additionally, there was no statistical difference in the Q angles between the isolated meniscal tears group and the contralateral knees. In this study, we observed significantly higher Q angle in the patient groups than controls. Conclusion: We were not able to show any association between the isolated meniscal tears and rotational alignments with the lower limb. This result suggest that the lower extremity torsional deformities cannot be regarded as primary etiological factor for the isolated meniscal tears. However, increased Q angles may be played a role as predisposing factors for meniscal tears.
