Abstract

Objectives: This prospective randomized study was designed to evaluate the safety and efficacy of polymer Polyactive B as a bone-graft substitute for filling up donor defects caused by removal of mosaicplasty grafts.Patients and methods: The study included 10 patients (7 males, 3 females) who underwent mosaicplasty using 6.5-mm grafts. The donor sites of the grafts were filled up with 2 to 6 pieces (average 3.5 pieces) of Polyactive B cylinders, 7.5 mm in diameter. The control group consisted of 10 patients in whom the donor sites were left empty. Surgical interventions were performed either arthroscopically or by open exposure. All the patients had preoperative, 3- and 9-month clinical scores; preoperative, 7-day, and 3-month magnetic resonance imaging (MRI) scans. Control arthroscopy was performed in all Polyactive B-filled patients and in four control patients nine months postoperatively.Results: No postoperative bleeding or other complications occurred. Clinical scores were similar in two groups. Magnetic resonance imaging showed congruent surfaces in all cases. In control arthroscopies, no signs of inflammatory reaction were seen. All surfaces of the filled donor areas were congruent, whereas mild protrusions were observed on the surfaces of the control areas. Macroscopically, the Polyactive B plugs were well integrated into the surroundings. Histological analysis showed proper subchondral ossification in each Polyactive-B case, and a large number of polymer fragments, suggesting partial biodegradation.Conclusion: The absence of inflammation and evidence of mild foreign body reaction suggest that the Polyactive B is biocompatible and may be appropriate to fill up the donor areas.

Özet

Amaç: Bu ileriye dönük randomize çalışmada, mozaikplasti için greft alımından sonra oluşan defektlerin doldurulmasında kemik grefti yerine kullanılan Polyactive B polimerinin güvenilirliği ve etkinliği değerlendirildi.Hastalar ve yöntemler: Çalışmaya, 6.5 mm boyutta greftlerle mozaikplasti uygulanan 10 hasta (7 erkek, 3 kadın) alındı. Greftlerin alındığı yerlerdeki defektler çapı 7.5 mm olan silindir şekline getirilen Polyactive B ile dolduruldu. Uygulamada ortalama 3.5 silindir (dağılım 2-6) kullanıldı. Kontrol grubunu oluşturan 10 hastada greftlerin alındığı yerler boş bırakıldı. Cerrahi girişimler artroskopi ile ya da açık görüş altında yapıldı. Tüm hastalar ameliyat öncesinde ve 3. ve 9. aylarda klinik skorlamayla; ameliyat öncesinde ve 7. gün ve 3. ayda manyetik rezonans görüntülemeyle (MRG) değerlendirildi. Polyactive B kullanılan tüm hastalara ve kontrol grubundaki dört hastaya ameliyat sonrası dokuzuncu ayda kontrol artroskopisi yapıldı.Bulgular: Hiçbir hastada ameliyat sonrasında kanama veya başka bir komplikasyon görülmedi. Klinik skorlar iki grupta benzer bulundu. Manyetik rezonans görüntülerinde hiçbir olguda eklem yüzeylerinde düzensizliklere rastlanmadı. Kontrol artroskopisinde enflamatuvar reaksiyon bulgusu yoktu; doldurulan alanlarda tüm yüzeyler düzgün idi; kontrol grubunda ise hafif yüzey düzensizlikleri gözlendi. Makroskobik olarak, Polyactive B tıkaçlarının çevre dokularla çok iyi bütünleştiği görüldü. Histolojik incelemede, Polyactive B uygulanan tüm olgularda yeterli subkondral ossifikasyon ve kısmi çözünmeyi gösteren çok sayıda polimer fragmanı gözlendi.Sonuç: Enflamasyon olmaması ve yabancı cisim reaksiyonunun çok hafif derecede olması Polyactive B’nin biyouyumlu olduğunu ve verici alanlardaki defektlerin doldurulmasında kullanılabileceğini göstermektedir.
