Abstract

Amaç:Bu çalışmanın amacı, hemstring otogrefti ile ön çapraz bağ (ÖÇB) rekonstrüksiyonu sonrası klasik rehabilitasyon programına eklenen eksentrik ve konsentrik egzersiz programının fonksiyonel sonuçlar üzerine etkisini incelemekti.

Çalışma planı: ÖÇB rekonstrüksiyonu olan 33 hasta, rastgele olarak çalışma (n=16; yaş ortalaması: 33.87±8.19) ve kontrol (n=17; yaş ortalaması: 32.64±8.21) gruplarına ayrılıp aynı ÖÇB rehabilitasyon programına alındı. Çalışma grubundaki hastalara ilave olarak cerrahiden sonra 3. haftadan başlayarak Monitörize Fonksiyonel Squat Sistemi ile 12 haftalık progresif eksentrik ve konsentrik bir egzersiz programı uygulandı. Gruplar cerrahi öncesi ve 16.hafta sonrasında diz ekstansör ve fleksörlerinin izokinetik kuvveti, fonksiyonel performans (dikey sıçrama, yatay sıçrama testi) ve Lysholm Diz Ölçeği, Ön Çapraz Bağ Yaşam Kalite Anketi (ÖÇB-YKA) skorları açısından karşılaştırıldı.

Bulgular: Dikey sıçrama testi (p=0.012), yatay sıçrama testi (p=0.027), Lysholm diz ölçeği (p=0.002) ve ÖÇB-YKA (p=0.000) sonuçları çalışma grubunda anlamlı derecede fazlaydı. Gruplar arasında diz ekstansör ve fleksör izokinetik kuvveti açısından fark kaydedilmedi (p>0.05).

Çıkarımlar: Hemstring otogrefti ile ön çapraz bağ (ÖÇB) rekonstrüksiyonu sonrası klasik rehabilitasyon programına eklenen eksentrik ve konsentrik egzersiz programı fonksiyonel sonuçları olumlu etkilemektedir.

Abstract

Objective:The aim of this study was to assess the functional results of an early onset progressive eccentric and concentric training in patients with autogen hamstring anterior cruciate ligament (ACL) reconstruction.

Methods: Thirty-three patients with autogenous hamstring ACL reconstruction were randomly divided into study (n=16, mean age; 33.87±8.19) and control (n=17, mean age; 32.64±8.21) groups and followed the same ACL rehabilitation program. Additionally, the study group followed a progressive eccentric and concentric training for 12 weeks on the Monitorized Functional Squat System (MFSS) beginning 3 weeks after surgery. The groups were compared according to the isokinetic strength of the knee extensors and flexors, functional performance (the vertical jump test, a single hop for distance test) and the Lysholm knee scale, the Anterior Cruciate Ligament-Quality of Life Questionnaire (ACL-QOL), before and 16 weeks after the surgery.

Results: The functional outcomes in terms of the vertical jump test (p=0.012), a single hop-for-distance test (p=0.027), the Lysholm knee scale (p=0.002) and the ACL-QOL questionnaire (p=0.000) demonstrated significantly greater improvement in the study group. No significant difference was reported between groups for isokinetic strength of the knee extensors and flexors (p>0.05).

Conclusion: Adding progressive eccentric and concentric exercises to the standard rehabilitation protocol may improve the functional results after ACL reconstruction with autogen hamstring grafts
