Purpose: The aim of this study was to investigate the effect of hip abductor strengthening exercises in addition to the knee muscle strengthening exercise program on knee functional recovery in patients who had undergone medial patellofemoral ligament reconstruction.
Methods: Thirty patients were included in the study. The patients were randomly assigned to the knee muscle strengthening exercise group and the hip abductor exercise group in addition to the knee strengthening exercises group and included in a 12-week exercise program. Kujala, (International Knee Documentation Committee) subjective knee evaluation form, Tegner and Lysholm scores were evaluated preoperatively at 3rd, 6th and 12th months after surgery.
Results: Knee scores were similar between the groups (p>0.05) in the preoperative period. Compared to the control group, Kujala (6th months: p=0.03, 12th months: p=0.03), International Knee Documentation Committee subjective knee evaluation form (3rd months: p=0.01, 6th months: p=0.01, 12th months: p=0.03) and Lysholm (3rd month: p=0.04, 6th month: p=0.04, 12th month: p=0.01) scores were higher in the study group at 6th and 12th months after surgery. Similarly, the Tegner activity score was higher in the study group at 12 months after surgery (p=0.04).
Conclusion: Hip abductor strengthening exercises in addition to the knee strengthening exercise program was more effective than only knee strengthening exercises in terms of improving knee functions in individuals who have undergone medial patellofemoral ligament reconstruction. Therefore, the inclusion of hip abductor exercises in the rehabilitation program will be important in terms of improving performance.

Medial patellofemoral ligament rekonstrüksiyonu sonrası kalça abduktör kas kuvvetlendirme egzersizlerinin diz fonksiyonu üzerine etkisi

Öz

Amaç: Bu çalışmanın amacı, medial patellofemoral ligament rekonstrüksiyonu geçirmiş hastalarda diz kas kuvvetlendirme egzersiz programına ek olarak yapılan kalça abduktör kuvvetlendirme egzersizlerinin fonksiyonel iyileşme üzerine etkisini araştırmak idi.
Yöntem: Çalışmaya 30 hasta dahil edildi. Hastalar randomize olarak diz kas kuvvetlendirme egzersiz grubu ve diz kuvvetlendirme egzersizlerine ek olarak kalça abduktör egzersiz grubuna ayrılarak 12 haftalık egzersiz programına dahil edildi. Hastaların preoperatif, postoperatif 3., 6. ve 12. aylarda diz fonksiyonları Kujala, (International Knee Documentation Committee) Subjektif Diz Değerlendirme Formu, Tegner ve Lysholm skorları ile değerlendirildi.
Bulgular: Diz skorları preoperatif dönemde gruplar arasında benzerdi (p>0,05). Kontrol grubuna kıyasla, 6. ve 12. aylarda Kujala (6. ay: p=0,03, 12. ay: p=0,03), International Knee Documentation Committee Subjektif Diz Değerlendirme Formu (3. ay: p=0,01, 6. ay: p=0,01, 12. ay: p=0,03) ve Lysholm (3. ay: p=0,04, 6. ay: p=0,04, 12. ay: p=0,01) skorları çalışma grubunda daha yüksek bulundu. Benzer şekilde, Tegner aktivite skoru çalışma grubunda, cerrahi sonrası 12. ayda daha yüksek idi (p=0,04).
Sonuç: Medial patellofemoral ligament rekonstrüksiyonu geçirmiş bireylerde diz kuvvetlendirme egzersiz programına ek olarak yapılan kalça abduktör kuvvetlendirme egzersizleri diz fonksiyonlarının iyileşmesi açısından sadece diz kuvvetlendirme egzersizlerine kıyasla daha etkiliydi. Bu nedenle rehabilitasyon programına kalça abduktör egzersizlerin dahil edilmesi, performansın gelişmesi açısından önemli olacaktır.
