Posterior root tear of the medial meniscus are well known. Although very rare, there are reports of anterior root tears of the medial meniscus but no reports on traumatic bony avulsion of the anterior medial meniscus root. This paper reports a case of an isolated bony avulsion of the anterior medial meniscus root, which was successfully repaired arthroscopically.

Purpose: In patients with meniscal tear with degenerative arthritis, controversy remains as to whether arthroscopic menisectomy is worthwhile or not. The purpose of this study was to evaluate the effect of arthroscopic medial meniscectomy in degenerative arthritis of the knee with meniscal tear. We also intended to identify pertinent indications and risk factors. Materials and Methods: 287 patients underwent arthroscopic medial meniscectomy from 2006 to 2008; 103 patients who had Kellgren-Lawrence grade II, III arthritis of the knee, were over 50 years old, and had minimum 1 year follow-up, were analyzed in this study. Clinical assessment was performed retrospectively using the arthroscopic surgery database, medical records, questionnires and interviews. Assessment included visual analogue scale (VAS) scores and Lysholm scores. Results: The mean Lysholm score increased from 69 to 85 after surgery. The mean VAS score improved from 7 to 3.1 after surgery. Kellgren-Lawrence grade II group and group with trauma history showed significant improvement of pain and function compared with grade III and group without trauma history. Outerbridge grade I showed significantly more improvement of pain than grade III and IV. Multiple regression analysis showed that trauma history and Outerbridge grade affect the improvement of Lysholm score. Conclusion: In one year follow-up, arthroscopic medial menisectomy can improve pain and function of patients in Kellgren-Lawrence grade II, III degenerative arthritis of the knee. We could expect good results especially in group with low Kellgren-Lawrence grade, trauma history, and mild articular cartilage lesion.

We report a case of a girl with a symptomatic anomaly of medial meniscus. The complaint of the patient was pain and snapping of the knee. The anterior horn of medial meniscus has anomalous insertion which was extended to the intercondylar notch of the femur on the surface of the anterior cruciate ligament, it attached to lateral wall of medial femoral condyle. This anomalous band was not detected in MRI of knee but found during the operation. After resection of anomalous band, the symptoms completely disappeared.

The posterior root of medial meniscus maintains normal meniscal function by circumferential hoop tension and prevents extrusion of meniscus and progression of osteoarthritis. A complete tear of posterior root of medial meniscus leads to loss of hoop tension, it is important to repair it and preserve the function of the medial meniscus. Recently, a variety of arthroscopic assisted reduction and repair techniques have been used. We create an arthroscopic all-inside suture technique using a 18 gauge spinal needle and suture anchor that is easier and more convenient compared with the previous techniques. So we report this technique with a review of current literatures.

Purpose: The object of this study is to compare the clinical results of noraml saline and Lactated Ringer's solution in the arthroscopic meniscus surgery on the knee. Materials and Methods: The study group included 64 patients who had an medial meniscus tear and received arthroscopic partial medial meniscectomy. The group I was normal saline group, which was used as an irrigation solution during operation. The group II was Lactated Ringer's solution group. We measured the visual analogue scale, painless active knee flexion angle, and the ratio of the knee swelling at postoperative one day for all patients. Results: The visual analogue scale and the painless active knee flexion angle were no significant differences in comparing with normal saline and Lactated Ringer's solution group. The ratio of the knee swelling in Lactated Ringer's solution group was significantly less than those of noraml saline group. Conclusion: Lactated Ringer's solution has an advantage of decreasing the knee swelling in the arthroscopic meniscus surgery on the knee.

Purpose: To examine the clinical results after arthroscopic meniscectomy of radial tear of medial meniscus. Materials and Methods: We studied 45 cases with the radial tear of medial meniscus which follow up more than 2 years(range 2 to 7 years). Arthroscopic surgery was performed to the patients with grade 0-2 according to the Kellgren and Lawrence classification. Evaluation of cartilage damage was performed on surgical photos according to Outerbridge classification. Evaluation of clinical result was used the modified Lysholm score. Results: The mean pre-operation Lysholm score was 79.1, 71.2, 68.5, 67.9, 67.2, 61.5 and post-operation Lysholm score was 86.3, 75.1, 73.0, 73.1, 73.2, 66.2 and 61.5%, 62.5%, 60.0%, 50.0%, 50.0%, 25.0% improved knee pain and 69.2%, 75.5%, 70.0%, 66.6%, 75.0%, 75.0% were satisfied knee surgery and 30.7%, 20.5%, 20.0%, 50.0%, 25.0%, 50.0% required further surgery in patients respectively. According to Kellgren and Lawrence classification, 7 cases(15.5%) progress grade 3 osteoarthritis. Conclusions: The radial tear of medial meniscus showed the poor results with arthroscopic meniscectomy even if the grade 0-2 osteoarthritis. For the improvement of the clinical results, consider the technique to restore the hoop stresses or use the high tibia osteotomy for preventing the osteoarthritis.

본 증례는 측두하악관절의 퇘행성 변화를 보이는 환자에서 악교정 수술의 시행 전에 중심위교합장치를 통해 측두하악관절의 안정화를 유도하고, 또한 골스캔을 이용하여 장치의 치료효과를 평가한 임상증례이다. 환자는 24세의 여성으로 5년 전부터 전치부 개교합이 발생되기 시작하였고, 고형식 저작시 좌측 전이부에 간헐적인 통증이 발생한다는 주소로 본원에 내원하였다. 임상검사상 촉진시 양측 관절낭 후방부에 압통을 호소하였으며, 각각 50, 45mm의 최대개구량 및 최대무통성 개구량을 보였다. 좌측 악관절부에서 단순 관절 잡음, 우측 악관절부에서 염발음이 청취되었으며, 저항검사 및 부하 검사에서는 특기할 반응을 보이지 않았다. 약 7mm의 전치부 개교합의 소견을 보였으며, 파노라마 사진과 횡두개 방사선 사진 소견상 양측 과두의 크기 및 하악지의 높이가 다소 작은 소견이 관찰되었고 자기공명영상 소견상 양측성 비정복성 관절원판의 전방전위가 관찰되었다. 1997년 10월 27일 첫 번째 골스캔 소견상 양측성 비정복성 관절원판의 전방위가 관찰되엇다. 골스캔의 전방 사진에서 Densitometer를 이용하여 좌, 우측 과두부위와 상악 골부위의 가장 어두운 부분의 흑화도를 측정하였다. 각각 3회씩 구하여 평균을 구하고 좌, 우측 과두 대 상악골의 흑화도의 비율을 계산하였다. 첫번째 골스캔의 평균 흑화도는 우측 과두, 좌측과두, 상악골이 각각 0.88, 0.81, 1.32 였다. 1997년 11월 4일 중심위교합장치를 장착하였고 지속적인 물리치료를 시행하였다. 1997년 12월 10일 두 번째 골 스캔을 평균 흑화도는 우측 과두, 좌측 과두, 상악골이 각각 0.33, 0.37, 088 이었다. 1998년 1월 30일 세 번째 골스캔 소견상 두 번째 골스캔과 비교하여 활성도가 감소된 소견을 보였다. 임상검사시 무통이었다. 1998년 2월 25일 술 전 교정 위해 중심위교합장치의 장작을 중지시켰다. 1998년 6월 5일 네 번째 골스캔 소견상 이전 검사들과 비교시 흡수가 감소된 소견을 보였다. 네 번째 골스캔의 평균 흑화도는 우측 과두, 좌측 과두, 상악골이 각각 0.24, 0.19, 0.85 였다. 현재 지속적인 관찰 중이며 본원 교정과에서 악교정수술 위한 술 전 교장을 시행중이다. 결국 첫 번째 골스캔의 과두 대 상악골의 평균 흑화도의 비율은 우측과 좌측이 각각 0.66, 0.61이었고 두 번째 골스캔에서는 우측과 좌측이 각각 0.37, 0.42였고, 네번째 골스캔에서는 우측과 좌측이 각각 0.28, 0.23 이었다. 각 골스캔의 과두 대 상악골의 평균 흑화도의 비율 사이에 유의한 차이가 있는지 검증하기 위해 Standard t-test 와 ANOVA를 시행하였다. 이상의 결과에서 첫 번째, 두 번째, 네 번째 골스캔으로 갈수록 좌, 우측 과두 대 상악골의 흑화도의 비율이 유의하게 감소했음을 알 수 있었다. 결론적으로 본 증례에서는 전치부 개교합이 발생되어 악교정수술이 필요한 환자에게 측두하악관절의 안정화를 위해 중심위교합장치를 사용함으로써 퇴행성 관절질환의 진행을 억제시킬 수 있고, 퇴행성 관절질환의 활성도에 대한 평가시 골스캔이 유용할 수 있음을 보여주었다고 사료된다.
