Abstract

Objective: There are several studies on medial open-wedge tibial osteotomy, but there isstill some debate about the acceptable amount of preoperative flexion contracture degree.Also, clinical effects of alteration of the tibial slope after the procedure are not clear. Thisstudy aimed to investigate the mid-term the clinical and radiological findings and complications of medial open-wedge tibial osteotomy.Methods: A total of 44 knees of 42 patients were retrospectively investigated betweenJanuary 2001 and February 2012. Tibial sagittal slope, mechanical tibiofemoral angle (mTFA),mechanical lateral distal femoral angle (mLDFA), and medial proximal tibia angle (MPTA)were measured both preoperatively and postoperatively. The mean follow-up period was92±7 (range 70–113) months. In four (10%) patients, 10 degrees of flexion contracture waspresent preoperatively. The clinical outcome was evaluated with the Hospital for SpecialSurgery (HSS) Knee Score, Oxford Knee Score (OKS), and Knee Outcome Survey-Activitiesof Daily Living Scale (KOS-ADLS).Results: The mean age of the participants was 45.7±18.3 (range 17–84) years. There were34 (81%) females and 8 (19%) males. The mean knee range of motion increased from 120±11to 130±9 degrees, postoperatively. The HSS scores improved to excellent in 29 (69%), goodin 9 (21%), and moderate in 4 (10%). The ADLS and Oxford scores improved two-fold.Conclusion: In conclusion, further studies are needed to understand the relationship between flexion contracture and tibial sagittal slope. Therefore, in selected patients, flexioncontracture may not be a restraint for osteotomy, especially if the slope increase is prevented.

Özet

Amaç: Medial açık kama tibial osteotomisi planlanan olgularda kabul edilebilir ameliyat öncesi fleksiyon kontraktürü miktarı hakkında tartışmalar halen devam etmektedir. Bu çalışmada medial açık kama tibial osteotomisinin orta dönem klinik, radyolojik bulguları ve komplikasyonları araştırıldı. Gereç ve Yöntem: Ocak 2001 ile Şubat 2012 tarihleri arasında 42 hastanın 44 dizi geriye dönük olarak incelendi. Ortalama takip süresi ise 92±7 (aralık, 70–113) ay idi. Tüm hastalar ameliyat öncesi ve sonrası HSS (Hospital for Special Surgery) Diz Skoru, OKS (Oxford Knee Score) ve KOS-ADLS (Knee Outcome Survey-Activities of Daily Living Scale) ile değerlendirildi. Bulgular: Ortalama yaş 45.7±18.3 (aralık, 17–84), Olguların 34’ü (%81) kadın, sekizi (%19) erkek idi. Ameliyat sonrası ortalama diz hareket açıklığı 120±11 dereceden 130±9 dereceye çıkmıştı. Ameliyat sonrası HSS skorları 29 (%69) hastada mükemmel, dokuz (%21) hastada iyi, dört hastada (%10) orta olarak saptandı. Ameliyat öncesi ADLS ve Oxford skorları sırasıyla 35.83±2.8 ve 42.58±4.5 iken ameliyat sonrasında 71.24±5.2 ve 21.62±4.4 olarak saptandı. Sonuç: Fleksiyon kontraktürü ve sagital tibial eğim arasındaki ilişkiyi anlamak için daha ileri çalışmalara ihtiyaç vardır. Bununla birlikte seçilmiş hastalarda tibial eğim artışı önlenebilirse ameliyat öncesi fleksiyon kontraktürü osteotomiye engel teşkil etmeyebilir.
