The Short-Term Results of Unıcondylar Knee Prosthesis in Patients with Body Mass İndex Over 35

Abstract

Objective: To evaluate the short-term results and complications of unicondylar knee prosthesis in obese patients with medial compartment arthrosis. Method: Unicondylar knee prosthesis was applied to 41 patients (36 females, 5 males; average age 56 years) with BMI >35 for the treatment of medial compartment arthrosis. Cementless Oxford phase 3 prosthesis was applied to all patients. Joint range of motion before and after surgery, VAS, OKS, and the KSS part 1 and part 2 scores of the patients were examined. Results: Flexion was measured as mean 115° (range, 90°- 135°) preoperatively, and 120° (range, 90° - 130°) postoperatively, extension as mean 0° (range, -10°- 0°) preoperatively and 0° (range,-15° - 0°) postoperatively, with no significant difference determined. The KSS Part 1 score was mean 58 (range, 36-82) preoperatively, and 85 (range, 57 - 96) postoperatively (p <0.001). The KSS part 2 score was 50 (range, 35- 80) preoperatively, and 90 (range, 51 -100) postoperatively (p <0.001). The Oxford score was mean 16 (range, 9 - 30) preoperatively, and 38 (range, 20 - 44) postoperatively (p <0.001). The differences between these scores were determined to be statistically significant. Complications developed in a total of 3 patients as periprosthetic joint infection in 1 patient (2.4%), and insert dislocation in 2 patients (4.9%). Conclusion: The study findings demonstrated that the application of unicondylar knee prosthesis is effective and successful in obese patients treated for medial gonarthrosis. There is a need for further long-term studies to confirm these results.

Abstract

Amaç:Bu çalışmada medial kompartman artrozlu obez hastalarda unikondiler diz protezinin kısa dönem sonuçlarınının ve komplikasyonlarının değerlendirilmesi amaçlandı. Gereç ve Yöntem: Medial kompartman artrozu tanısıyla BKİ >35 olan 41 hastaya(36 kadın 5 erkek;ort.yaş 56)unikondiler diz protezi uygulandı.Tüm hastalara Oxford faz 3 çimentosuz protez kullanıldı.Hastalar ameliyat öncesi ve sonrası eklem hareket açıklığı,VAS,OKS,KSS part 1 ve KSS part 2 skorlamasına göre değerlendirildi. Bulgular: Hastaların preop fleksiyonları ortalama 115 (90; 135) derece postop fleksiyonları ortalama 120 (90; 130) derece, preop ekstansiyonları ortalama 0 (-10; 0) derece postop fleksiyonları ortalama 0 (-15; 0) derece olup anlamlı fark saptanmamıştır.Hastaların preop KSS Part 1 58 (36; 82) postop 85 (57; 96)(p <0.001), preop KSS Part 2 50 (35; 80) postop 90 (51; 100) (p <0.001), preop Oxford skoru 16 (9; 30) postop 38 (20; 44) (p <0.001) olup istatistiksel olarak anlamlı bulunmuştur.1 hastada (%2.4) periprostatik eklem enfeksiyonu ,2 hastada (%4.9) insert çıkığı olmak üzere toplamda 3 hastada(%7,3) komplikasyon saptandı. Sonuç:Bulgularamız,obez hastalarda unikondiler diz protezi uygulamasanın medial gonartroz tedavisinde kısa dönemde etkili ve başarılı olduğunu göstermektedir.Uzun dönem sonuçlar için daha uzun takip süreli çalışmalara ihtiyaç vardır.
