배대경,임창무,정기웅,Bae, Dae Kyung,Yim, Chang Moo,Jeong, Ki Woong 대한관절경학회 1999 대한관절경학회지 Vol.3 No.1

목적 : 본 논문의 목적은 반월상 연골 파열의 치료에서 meniscal arrow의 역할을 분석하는데 있다. 대상 및 방법 : 1997년 5월부터 1998년 8월까지 반월상 연골이 파열되어 meniscal arrow를 사용하여 봉합한 22명 22례를 대상으로 하였다. 추시 기간은 평균 14.7개월(7~22개월)이었으며, 평균 연령은 27세(18~51세)였다. 성별은 남자 19명, 여자 3명이었고 우측이 12례, 좌측이 10례였다. 동반손상은 전방십자인대 파열이 16례, 내측 측부인대 손상이 1례였으며, 파열위치는 후각부가 19례, 중앙부가 3례였다. 연골판의 파열 형태는 종파열이 14례, bucket handle형 파열이 7례, 수평 파열은 1례였고, 환자 1례당 봉합을 위하여 사용된 meniscal arrow는 평균 2.5개(1-4개)였다. 임상적 결과의 판정은 Tapper와 Hoover의 분류를 기준으로 하였고, 술 후 운동범위를 측정하였으며, 동통, 잠김, 불안정 등의 주관적 증상의 변화를 관찰하였다. 또한 수술시 연골 봉합술에 소요된 시간을 측정하였다. 결과 : 임상적 결과는 우수가 16례, 양호가 4례 그리고 보통이 2례 였다. 최종 추시시 운동 범위는 평균 135도(120~140도)였으며 1례를 제외한 모든 환자에서 동통, 잠김, 불안정 등을 호소한 례는 없었다. 수술시 연골의 봉합술에 소요된 시간은 평균 25분(15-40분)이었다. 22례 중 이차 관절경을 시행한 환자 3례 모두에서 파열 부위는 완전 치유되어 있음을 관찰할 수 있었다. 결론 : Meniscal arrow는 반월상 연골 파열에 대하여 동반손상이나 파열부위에 따라 선택적으로 사용하는 것이 바람직할 것으로 사료된다. Purpose : The purpose of this paper is to analyze the clinical results after meniscal repair using meniscal arrow. Materials and Methods : Between May 1997 and Aug 1998, we repaired 22 tom menisci in 22 patients using meniscal arrows. There were nineteen males and three females with an average age of 27 years. There were longitudinal tear in 14 cases, Bucket-handle tear were 7 cases and horizontal tear was in 1 case. In 22 meniscus tears, 16 cases were associated with anterior cruciate ligament tear. Average number of meniscal arrow that was used were 2.5(ranged 1 to 4). Average follow-up period was 14.7 months(ranged 6 to 22 months). We evaluated the clinical results by the Tapper and Hoover's grading system. Results : There were excellent in 16 cases, good in 4 cases and fair in 2 cases on the clinical results. At the last follow up, the range of the motion of the knee joint were average 135 degrees(ranged 125 to 140 degrees). Mean time elapsed for meniscal repair were 25 minutes(ranged 15 to 40 minutes). Conclusion : Meniscal arrow has many advantages such as short operative time, easy fixation technique, and less neurovascular injury. We think that arthroscopic meniscal repair using meniscal arrow is effective treatment method in selected patient who have longitudinal, bucket-handle tear at the posterior hom associated with anterior cruciate ligament tear.

The objective of this study is to assess the role of articulating spacer in two stage reimplantation of infected TKA. Fifteen patients with deep infected total knee arthroplasties were treated by two stage reimplantation protocol between Jan. 1987 and Oct. 1997. Seven cases in Group A were treated by debridement, removal of the prosthesis and placement of antibiotic impregnated cement spacer before reimplantation. Eight cases in Group B were treated by debridement, and reinsertion of the retrieved implant after autoclaving with antibiotic impregnated cement fixation. The average follow-up period was 77 months(range, 28-141 months) in group A, and 25 months(range, 12-63 months) in group B. The average knee flexion after revision was 82 degrees in group A, and 106 degrees in group B. The average HSS knee rating score was 80 points in group A, and 88 points in group B. No patient had recurrence of infection during the follow-up period. In conclusion, our method using articulating spacer allowed early range of motion and partial weight bearing during the spacer phase. This methods also delivered high local concentration of antibiotics and kept the functional joint before a second-stage reimplantation.

A case of consumptive coagulopathy due to pseudoaneurysm, which occured as a complication of intramedullary nailing, was rarely reported. Pseudoaneurysm of peripheral artery is presented with pulsating mass and may show extrinsic indentations of the adjacent bone. The coagulopathy and bleeding responded to surgical elimination of the fistula and aneurysm. Diffuse intravascular coagulopathy or consumptive coagulopathy is infrequently associated with pseudoaneurysm of deep femoral artery. Laceration of major arteries are more common in open than in closed fractures. They usually occur only when a major artery is in close proximity to bone as complications to fracture. Diffuse intravascular coagulopathy or consumptive coagulopathy is characterized clinically by excessive bleeding, ecchymosis and petechiae and by laboratory evidence of a disease in the numbers of platelets and amount of fibrinogen and an increase of fibrin degradation products with prolonged prothrombin and partial thromboplastin times. When the two coexist, they create a difficult clinical problem that requires optimal medical and surgical treatments. If the appropriate treatment was delayed, serious complication such as sepsis or death could be occured. Prompt recongnition through appropriate laboratory tests and early surgical intervention was indicated essentially, We are reporting one case of coagulopathy associated with pseudoaneurysm of deep femoral artery that presented to the broad clinical picture.

Generally, exposure and the operative technique are common difficulty encountered in the total knee arthroplasty of ankylosed knee due to old infection sequelae. Also the postoperative range of motion and relief of pain is poor due to deformity and excessive soft tissue contracture around knee. There have heen few reports, however, that address the reconstructive challenge of total knee arthroplasty in a previously infected ankylosed knee. We performed TKA in thirty six patients who had ankylosed knee between July l986 and Dec. 199S. After follow up of average five years and one month, we analysed the results. The definition of ankylosis was a knee ROM less than 90 degree. Average age of patients were 36.7 years old. Twelve patients were men and twenty four patients were women. Sixteen patients of partial ankylosis and twenty patients of complete ankylosis were performed operation. There were nineteen cases of healed tubercuiosis knees and seventeen cases of healed pyogenic knees. For the release of soft tissue contracture in 9 cases, we lengthened quadrceps tendon with the method of modified V-Y advancement technique. Patella tendon was proximally reattached with staples and suture in 6 cases and tibial tubercle was proximally transferred in 3 cases. As results, the postoperative average range of motion was 79.3˚ (30˚ - l21˚) in complete ankylosis, 107˚ (60˚ - 135˚) in partial ankylosis. The average Hospital for Special Surgery knee rating score improved from 56.3 points preoperatively to 84.8 points postoperatively. Radiolucent line was observed in two Knees with less than 2mm width in three years and four months, and four years postoperatively, but the patient had no pain. In five patients who had poor gain of range of motion after operation, we perfonned arthroscopic adhesiolysis. In conclusion, regarding patient selection, reasonable bony development, relative]y healthy extensor mechanism and adequate soft tissue condition are important for success of TKA in old intection sequelae. TKA of ankylosed knee in old infection sequelae is a successful procedure which can obtain the restoration of function of the ankylosed knee.

Discoid meniscus is an uncommon cause of internal derangement of the knee joint. The discoid medial meniscus is much less common than the discoid lateral meniscus. A 15-year-old male student had a incomplete discoid medial meniscus of right knee combined with a horizontal tear. This was confirmed by magnetic resonance imaging(MRI) and arthroscopic procedure. Partial meniscectomy was performed arthroscopically. An unevenful recovery followed. We report a case of discoid medial meniscus with brief review of literature.
