不少年青人都熱愛做運動,保持身體健康,鍛鍊體魄。不過,過度運動或姿勢不當除了使人感到勞累外,還容易引致關節及筋肉受傷。其中較常見因運動而受傷的嚴重膝部病症有「創傷性膝關節軟骨損傷」。
顧名思義,創傷性膝關節軟骨損傷是指膝關節的軟骨因外在創傷而受到損害。患者一般會出現膝關節機械性疼痛和腫脹,長遠來說有可能導致膝關節提早老化。過去,創傷性膝關節軟骨損傷的手術治療大致分為兩種。第一種方法是將患處的皮質骨穿刺(marrow stimulation technique),引發類軟骨的傷疤組織形成,可是這種療法的效用不大。第二種方法是將患處旁的正常軟骨移植到患處(osteochondral grafting),可是這種方法有可能會引致膝關節出現更多病徵 。
自體軟骨細胞移植(Autologous chondrocyte implantation)是近十至十五年間發展的治療創傷性膝關節軟骨損傷的手術。這種手術需要分為兩個階段進行。第一階段,醫生會為患者進行關節鏡手術,在病人膝關節內抽取小量軟骨細胞樣本以供在實驗室內進行培植。第二階段的手術將於第一階段手術的六至八星期後進行。醫生會把培植好的新軟骨,以傳統開放式手術或微創手術,放到病人的患膝處。手術完成後,病人將展開為期半年至一年、進度十分緊密的復康療程,以確保移植的軟骨在患處的生長及癒合情況理想。
