Abstract

Aim: In this study, we aimed to compare outcomes of anterior cruciate ligament (ACL) reconstructions using bone–patellar tendon–bone graft (BPTG) or hamstring tendon graft (HTG) with cross-pin fixation at the femoral side.

Materials and Methods: The retrospective observational study included records of 100 patients who underwent ACL reconstruction with femoral cross-pin fixation between May 2008 and August 2012. The patients were divided into two groups according to the graft type used: the BPTG group and the HTG group. The preoperative and postoperative 6th-month Tegner Lysholm Knee Scoring Scale (TLKS) scores, International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC-SKF) scores, and Lachman test results were compared. The effects of meniscus lesion presence on the outcomes were also investigated.

Results: Of the 100 patients, 93 were male and 7 female. The HTG and BPTG groups consisted of 62 and 38 patients, respectively. The mean age was 24.1±4.9 (18–38) years for the HTG group and 32.1±6.8 (21–54) years for the BPTG group. The mean pre- and postoperative TLKS scores were respectively 50.5 and 94.3 in the BPTG group, and 49.9 and 95.2 in the HTG group. The mean pre- and postoperative IKDC-SKF scores were 51.3 and 95.6 in the BPTG group, and 51.8 and 95.6 in the HTG group. The postoperative score improvement was statistically significant in all patients (p<0.05), but there was no significant difference between the two groups. The postoperative improvement in knee stability was statistically significant in all patients (p<0.05). The postoperative score improvement was less in patients with meniscal injury (p<0.05).

Discussion and Conclusion: We found no significant difference between the two groups in terms of functional knee scores. However, the presence of meniscus lesions negatively affects the postoperative outcomes.

Femoral Cross-pin Fiksasyonu ile Patellar Tendon veya Hamstring Tendon Otogrefti Kullanılan Ön Çapraz Bağ Rekonstrüksiyonlarının Sonuçlarının Karşılaştırılması

Abstract

Amaç: Bu çalışmada femoral tarafta cross-pin fiksasyonu ile kemik–patellar tendon–kemik grefti (KPTG) veya hamstring tendon grefti (HTG) kullanılan ön çapraz bağ (ÖÇB) rekonstrüksiyonlarının sonuçlarını karşılaştırmak amaçlanmıştır.

Gereç ve Yöntemler: Retrospektif gözlemsel çalışmamız Mayıs 2008—Ağustos 2012 döneminde femoral cross-pin fiksasyonlu ÖÇB rekonstrüksiyonu uygulanmış olan 100 hastanın kayıtlarını kapsadı. Hastalar, kullanılan greft türüne göre iki gruba ayrıldı: KPTG grubu ve HTG grubu. Preoperatif ve postoperatif 6. ay Tegner Lysholm Diz Skorlama Skalası (TLDS) skorları, Uluslararası Diz Dokümantasyon Komitesi Subjektif Diz Değerlendirme Formu (UDDK-SDF) skorları ve Lachman test sonuçları karşılaştırıldı. Ayrıca menisküs lezyonu varlığının sonuçlar üzerindeki etkisi incelendi.

Bulgular: Yüz hastanın 93’ü erkek, 7’si kadındı. HTG ve KPTG grupları sırasıyla 62 ve 38 hastadan oluştu. Ortalama yaş HTG grubu için 24,1±4,9 (18–38) yıl, KPTG grubu için 32,1±6,8 (21–54) yıl idi. Sırasıyla operasyon öncesi ve sonrası ortalama TLDS skorları KPTG grubu için 50,5 ve 94,3, HTG grubu için 49,9 ve 95,2 idi. Operasyon öncesi ve sonrası ortalama UDDK-SDF skorları KPTG grubu için 51,3 ve 95,6, HTG grubu için 51,8 ve 95,6 idi. Postoperatif skorlardaki yükseliş tüm hastalarda istatistiksel olarak anlamlıydı (p<0,05); fakat iki grup arasında anlamlı fark yoktu. Diz stabilitesindeki postoperatif artış tüm hastalarda istatistiksel olarak anlamlıydı (p<0,05). Menisküs yaralanması olan hastalarda postoperatif skorlardaki yükseliş daha azdı (p<0,05).

Tartışma ve Sonuç: İki grup arasında fonksiyonel diz skorları açısından anlamlı bir fark tespit edilmemiştir. Fakat menisküs lezyonu varlığı postoperatif sonuçları negatif etkilemektedir.
