Purpose: To compare the clinical outcomes after meniscus allograft transplantation between lateral and medial or isolated and combined procedure groups. Materials and Methods: Of the patients who had undergone arthroscopic meniscal allograft transplantation between Dec. 1997 and Jun. 2007, 52 patients were available for retrospective evaluation. Patients were grouped into lateral(33 cases) and medial(19 cases) transplant groups as well as those with isolated(18 cases) and combined(34 cases) procedure. The average age was 34.2 years and the mean follow-up period was 42.2 months. Postoperative range of motion (ROM), visual analog scale (VAS), International Knee Documentation Committee (IKDC) subjective score, Lysholm score, Tegner score, patient's subjective satisfaction, $2^{nd}$ look arthroscopy and MRI were evaluated retrospectively. Results: Mean postoperative ROM was $130.3^{\circ}$. The VAS showed an improvement from 5.96 to 3.05 at the last follow up. IKDC subjective score and Lysholm score also showed an improvement from 46.5 to 64.5 and from 61.9s to 79.58 respectively. Tegner score was improved from 2.9 to 3.6. Overall, 61.5% of patients reported they were completely or mostly satisfied with procedure. There were no significant differences noted between lateral and medial groups as well as isolated and combined groups. In 2nd look arthroscopy, 10 of 18 cases showed good pheripheal healing and there were 6 cases of partial and 2 of complex tear. We observed graft subluxation or extrusion in 12 of 16 cases who were evaluated with follow-up MRI. Conclusion: Meniscus allograft transplantation alone or in combination with other procedure showed an improvement in knee pain and clinical score. But there were no significant difference between lateral and medial groups or isolated and combined procedure groups.

Complete radial tears of the lateral meniscus are relatively rare. Once torn, the injury can be debilitating due to disruption of the circumferential fibers of the meniscus. We experienced a case of a lateral meniscus with a complete radial tear at the midbody, where the two torn ends were displaced more than 1 cm and could not be approximated during arthroscopy. Thirteen months after surgery, follow-up MRI and second-look arthroscopic findings showed that the complete radial tear has healed spontaneously. However, twenty nine months after the second-look arthroscopy, the patient complained of severe knee pain during exercise. On follow-up MRI, increased sclerosis and newly developed bone marrow edema were observed in the lateral femoral condyle, compared with previous MR images. Finally, we performed meniscal allograft transplantation due to the defective properties of the completely healed lateral meniscus.

The first human meniscal allograft transplantations (MATs) were performed 30 years ago. In the early era, candidates were limited to patients who have favorable joint conditions. MAT is currently indicated for patients with post-meniscectomy symptoms, such as compartmental pain or effusion after a subtotal or total meniscectomy. The current indication for MAT is being expanded to other patients who were not indicated previously. The present article reviews how the indications of MAT have changed over the years.

The meniscus is considered "extruded" when it extends beyond the tibial margins more than 3 mm in a coronal view of magnetic resonance imaging (MRI). However, identifying the meniscal extrusion intraoperatively may be difficult because of the simple fact that most of the arthroscopic procedures are done in knee flexion position while follow up MRI studies area taken at knee extension position. Here, we demonstrate the arthroscopic technique for evaluating the meniscal extrusion.

동종 반월상 연골 이식술은 불가피하게 반월상 연골이 소실된 환자에서 증상을 호전을 위한 매우 효과적인 치료이다. 관절연골의 보호 효과 등 장기적인 결과에 대해서는 아직까지는 많은 연구가 필요한 상태이지만, 이러한 환자에서 반월상 연골의 기능을 회복시키기 대안이 많아 점차 널리 시행되는 추세이다. 이식된 반월상 연골이 제 기능을 하기 위해서는 적절한 수술방법을 통하여 반월상 연골 이식물을 정확한 위치에 이식을 하는 것은 필수적일 것이다. 여러 저자들 마다 서로 다른 다양한 반월상 연골 이식술의 방법들을 사용하고 있지만, 어떤 방법을 선택하던지 간에 이식된 반월상 연골의 전각 및 후각을 해부학적인 위치에 견고하게 고정을 하는 것이 매우 중요하다. 술자의 선호도에 따라 다양한 방법중의 하나를 선택을 할 수 있지만, 어떤 방법이든 수술 술기상의 어려움이 있으므로, 철저한 준비와 노력이 필요할 것이다. 본 종설에서는 반월상 연골 이식술 중 개방적 방법에 대한 간단한 소개와 함께 저자들이 사용하는 관절경을 이용한 수술방법을 정리하였다.
