Objective: This study aimed to investigate the impact of varus deformity correction on functional and clinical outcomes following unicompartmental knee surgery.
Materials and Methods: A total of 71 medial unicompartmental knee arthroplasties (UKA) in 51 patients were included in this study. The knees were categorized based on the degree of correction observed in standing orthoroentgenograms post-surgery (Group 1: 0-4.9° correction, Group 2: 5-9.9° correction, and Group 3: 10° or more correction). Functional knee evaluation was assessed using range of motion measurements, posterior tibial slope angles, visual analogue score (VAS), Knee Society Score (KSS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Oxford Knee Score (OKS) questionnaires.
Results: Following UKA surgery, there was a significant improvement in all patient-reported outcome scores, posterior tibial slope angles, visual analogue scores, and range of motion measurements across all groups. However, no significant differences were observed when comparing postoperative scores between the groups.
Conclusion: Patients with varus deformities of up to 15 degrees can safely undergo UKA surgery without compromising clinical and functional outcomes.

Amaç: Bu çalışmanın amacı, unicompartmental diz cerrahisi sonrası varus deformite düzeltiminin fonksiyonel ve klinik sonuçlar üzerindeki etkisini araştırmaktır.
Gereç ve Yöntem: Bu çalışmaya 51 hastada 71 medial unicompartmental diz artroplastisi (UKA) dahil edildi. Dizler, ameliyat sonrası ayakta çekilen ortoröntgenogramlarda gözlenen düzeltme derecesine göre gruplandırıldı (Grup 1: 0-4.9° düzeltme, Grup 2: 5-9.9° düzeltme ve Grup 3: 10° veya daha fazla düzeltme). Fonksiyonel diz değerlendirmesi, hareket açıklığı ölçümleri, posterior tibial eğim açıları, görsel analog skor (VAS), Knee Society Skoru (KSS), Western Ontario ve McMaster Üniversiteleri Osteoartrit İndeksi (WOMAC) ve Oxford Diz Skoru (OKS) anketleri kullanılarak yapıldı.
Bulgular: UKA cerrahisi sonrası, tüm gruplarda tüm hasta bildirilen sonuç skorlarında, posterior tibial eğim açılarında, görsel analog skorlarda ve hareket açıklığı ölçümlerinde önemli bir iyileşme görüldü. Ancak, gruplar arasında postoperatif skorları karşılaştırırken anlamlı farklar gözlenmedi.
Sonuç: 15 dereceye kadar varus deformitesi olan hastalarda klinik ve fonksiyonel sonuçlar açısından güvenle UKA cerrahisi uygulanabilir.
