A ganglion can arise as a cystic lesion from a tendon sheath or a joint capsule and contain a glassy, clear, and jelly-like fluid. They can occur within muscles, menisci, and tendons. Intra-articular ganglion cysts of the knee joint are rare. We report on three ganglion cysts of the cruciate ligaments: Two were intercruciate, and one was located around the posterior cruciate ligament.
The clinical diagnosis was established using magnetic resonance imaging. All patients were treated successfully using arthroscopic debridement by basket punch and shaver. Subsequent histological examination confirmed the diagnosis.
All three patients were asymptomatic at the postoperative follow-up of 16-36 months.
A review of the literature reveals a controversial discussion about the clinical significance as well as the etiology of ganglion cysts arising from the cruciate ligaments. These case reports show that an intra-articular ganglion cyst of the cruciate ligaments is difficult to diagnose. A cyst does not necessarily have to be associated with specific clinical symptoms or a previous trauma. Preoperatively, MRI is essential when diagnosing ganglion cysts of the knee joint. An intra-articular ganglion cyst of the knee joint can be successfully treated by arthroscopy.
腱鞘囊肿可作为一种囊性病变起源于腱鞘或关节囊,内含透明、清澈、果冻样液体。它们可发生于肌肉、半月板和肌腱内。膝关节内腱鞘囊肿罕见。我们报告3例十字韧带腱鞘囊肿:2例位于十字韧带之间,1例位于后交叉韧带周围。
通过磁共振成像进行临床诊断。所有患者均成功接受关节镜下篮钳和刨削器清创治疗。随后的组织学检查证实了诊断。
所有3例患者在术后16 - 36个月的随访中均无症状。
文献回顾显示,关于十字韧带腱鞘囊肿的临床意义及病因存在争议性讨论。这些病例报告表明,十字韧带内腱鞘囊肿难以诊断。囊肿不一定与特定临床症状或既往创伤相关。术前,磁共振成像对于诊断膝关节腱鞘囊肿至关重要。膝关节内腱鞘囊肿可通过关节镜成功治疗。
