Does the Cannulated Screw Tension Band Improve Quadriceps Muscle Strength, Atrophy, Implant Irritation and Functional Results in Patella Fractures Compared to the Kirschner Wire Tension Band?

Background: We aimed to evaluate the effects of the cannulated screw tension band and Kirschner (K) wire tension band methods on quadriceps muscle strength and atrophy, implant irritation and functional results in the treatment of patella fractures. Materials and Methods: In this study, 70 patients with a diagnosis of patella fracture, who were operated in our clinic between January 2015 and May 2019, were retrospectively evaluated. Patients were operated in two separate groups: in group 1, 21 patients were fitted with a cannulated screw tension band, and in group 2, 49 patients were treated by the K wire tension band method. The Lysholm score was used for clinical evaluation. The loss of extensor muscle strength in the patients was measured with an analogue dynamometer. Results: There was no difference in the effect of two different techniques, age, gender, and fracture type on the duration of fracture union in the surgical treatment of patella fractures (p>0.05). Clinically, there was no difference in Lysholm score between the two groups (p>0.05). Knee extensor muscle strength decreased in both groups compared to the healthy side (p<0.05), and the two groups were similar (p>0.05). We found that the thigh diameter was decreased compared to the healthy side in patients who underwent surgery for patella fracture (p=0.001). There was no difference in thigh diameter difference between the two groups (p>0.05). Conclusion: With the two different techniques, quadriceps muscle strength, atrophy and clinical results were similar. In the K-wire tension band method, more implant removal was required due to irritation. [ABSTRACT FROM AUTHOR]

Amaç: Patella kırıklarının tedavisinde kanüllü vida gergi bandı ve Kirschner (K) teli gergi bandı yöntemlerinin kuadriseps kas gücü ve atrofisi, implant iritasyonu ve fonksiyonel sonuçlar üzerindeki etkilerini değerlendirmeyi amaçladık. Gereç ve Yöntemler: Bu çalışmada Ocak 2015-Mayıs 2019 tarihleri arasında kliniğimizde patella kırığı tanısı alan 70 hasta retrospektif olarak değerlendirildi. Hastalar iki ayrı grupta ameliyat edildi: Grup 1'de 21 hastaya kanüllü vida gergi bandı uygulandı ve grup 2'de 49 hasta K tel gergi bandı yöntemi ile tedavi edildi. Lysholm skoru klinik değerlendirme için kullanıldı. Hastalarda ekstansör kas gücü kaybı analog dinamometre ile ölçüldü. Bulgular: Patella kırıklarının cerrahi tedavisinde iki farklı tekniğin, yaş, cinsiyet ve kırık tipinin kırığın kaynama süresi üzerine etkisinde fark yoktu (p>0,05). Klinik olarak Lysholm skorunda iki grup arasında fark yoktu (p>0,05). Her iki grupta diz ekstansör kas gücü sağlıklı tarafa göre azaldı (p<0,05) ve iki grup benzerdi (p>0,05). Patella kırığı nedeniyle ameliyat edilen hastalarda uyluk çapının sağlıklı tarafa göre azaldığını saptadık (p=0,001). İki grup arasında uyluk çapı açısından fark yoktu (p>0,05). Sonuç: Kuadriseps kas gücü, atrofi ve klinik sonuçlar iki farklı teknikle benzerdi. K-teli gergi bandı yönteminde tahriş nedeniyle daha fazla implant çıkarılması gerekiyordu. [ABSTRACT FROM AUTHOR]
