  • Purpose: The purpose of this preliminary report is to investigate the short term outcome of performing gel type fibrin matrix autologous chondrocyte implantation to patients who have damaged knee joint cartilage using secondary arthroscopy. Material and Methods: Six patients who have damaged knee joint cartilage were involved. The average size of defect was $5.13\;cm^2$. While performing primary arthroscopy, whole layer of cartilage bone was obtained either from the margin of damaged cartilage or the bilateral margin of a trochlea. The cartilaginous cells were obtained for culture for four to six weeks. While performing secondary minimal invasive arthrotomy, gel type fibrin matrix autologous chondrocyte was implanted on the chondral defect site. Results: 4 among 6 patients to be more than good in Modified Cincinnati Knee Scoring system. Lysholm function score was 59.5 preoperatively, and it improved to 76.25. ICRS grading by performing secondary arthroscopy revealed 4 out of 6 patients to be nearly normal. Conclusion: Gel type fibrin matrix autologous chondrocyte implantation is a treatment for cartilage defect, which takes less time to operate than the conventional implantation. In addition, this method minimizes the size of incision and allows arthroscopic surgery. However, long term follow up and more case study is thought to be necessary.

  • Purpose: The purpose of this study is to evaluate the clinical results for the treatment of osteoarthritis of the knee by arthroscopic procedure according to presence or absence of mechanical symptoms. Materials and Methods: We studied sixty patients (60 knees) who underwent arthroscopic procedure for the treatment of osteoarthritis of the knee from October,2000 to January,2002. The average follow up period was 15 months(12-30 months). We evaluated the mechanical symptoms by simple radiographs, history taking and physical examination. We analysed the clinical results by Baumgaertner's scale. Results: The Baumgaetner's score improved from 3.1 preoperatively to 8.1 postoperatively in the group with mechanical symptoms, whereas the scores in the group without mechanical symptom improved from 3.5 preoperatively to 5.4 postoperatively. The patients with mechanical symptoms were satisfied more than the patients without mechanical symptoms. Conclusion: The arthroscopic surgery could be one of good alternative treatment methods for the osteoarthritis of the knee with mechanical symptoms . But, more than these patients will be needed for further evaluation.

  • Purpose : To validate the arthroscopic synovectomy for the treatment of hemophilic knee. Materials and Methods: From January 1996 to January 2001, 28 arthroscopic synovectolny were performed in 26 patients with hemophilic arthropathy of the knee. The mean age was 17.8 years. The mean follow-up period was 3 years 11 months. We used six portals (two anterior, two suprapatellar and two posterior) and posterior trans-septal portal in all cases. Result : The mean frequency of hemarthrosis was 4 times per month preoperatively and 2 postoperatively. The mean amount of factor replacement was 4,633 units preoperatively and 1,505 postoperatively. The mean range of motion was $112^{\circ}$ preoperatively and $107^{\circ}$ postoperatively. On radiographic evaluation, three cases were progressed at the latest follow-up. On the subjective evaluation, significant or moderate improvement were in 19 cases $(68\%)$, and no improvement or deterioration in 9 cases $(32\%)$. Conclusion : With complete synovectomy through the appropriate arthroscopic portals, arthroscopic synovectomy of the knee in hemophilic patients is the successful method in decreasing bleeding episodes, amount of factor replacement, knee pain and preventing or delaying onset of end-stage hemophilic arthropathy.

  • Purpose : The purpose of this study is to evaluate the clinical outcomes and radiological changes after reconstruction of anterior cruciate ligament with human allograft. Material and Method : Authors analyzed 22 cases of anterior cruciate ligament allograft reconstruction which were done from January, 1995 to December, 1998 and could be followed up for a year or more. All cases were followed and reviewed in terms of anterior drawer test, Lachman test, Pivot shift test, radiographic examination, knee range of motion, and side-to-side difference of anteroior tibial translation using CA-4000 knee motion analyzer, and Lysholm knee scoring system. Result : The mean Lysholm knee score was 54 preoperatively and improved to 81 postoperatively by average of 27. The side-to-side difference of anterior tibial translation using CA-4000 knee motion analyser was less than 3 mm in 16 cases$(73\%)$, between 3 and 5 mm in 4 cases$(18\%)$, and greater than 6 min in 2 cases$(9\%)$. Average tibial tunnel enlargement was 1.5 mm, but there were not any osteoiysis or cystic formation along the tunnel and no relationship between tunnel enlargement and clinical outcome. Conclusion : Although this study had limited cases, clinical results of anterior cruciate allograft reconstruction were similar to those of reconstruction with autograft reported in the literatures. We think that allograft is an acceptable substitute fer autograft in anterior cruciate ligament reconstruction.

  • The meniscal cyst of knee joint is a rare disease, and the discoid meniscal cyst has not been reported in Korea. We report 3 cases of the discoid meniscal cyst confirmed by MRI and arthroscopy. In physical examination, all cases have tenderness of the knee joint. One has palpable mass of knee joint and the other one has limitation of knee motion with knee flexion contracture of 10 degrees and positive McMurray test at external rotation of the knee. All cases are complete discoid meniscus, which are, one medial discoid meniscus and two lateral discoid meniscus through MRI. We confirmed horizontal tear of meniscus in all cases and the location of meniscal cysts are anterior hem of meniscus in one and body of meniscus in two. We could get excellent results in all 3 cases that return to normal knee range of motion.

  • Purpose: This study compared the effects of a buprenorphine transdermal patch (BTDP) on the chest and knee for pain control after total knee arthroplasty (TKA). Materials and Methods: A retrospective case-control study was conducted from August 2018 to August 2019 on 231 patients who underwent TKA. Two hundred cases were selected considering age, sex, and body mass index. Before and after applying the BTDP, the Numeric Rating Scale (NRS), adverse effects and compliance were measured. All measurements in the chest application group (group A=100) and knee application group (group B=100) were compared. Results: NRS was similar in rest between the groups treated with BTDP, but at two days and three days afternoon, five, six, and seven days postoperatively in group B, the NRS was significantly lower than that of group A. The adverse effects of the central nervous system and gastrointestinal system after applying BTDP were significantly lower in group B than in group A. No significant differences in adverse effects of the cardiovascular system and skin were observed between the two groups. Regarding the maintenance of BTDP, group B was significantly higher than group A. Conclusion: The direct application of BTDP after TKA to painful knee joints showed excellent results in early postoperative pain control and can be a useful method for increasing patient compliance by reducing the frequency of adverse effects.

  • The purposes of this study were to measure the ranges of motion in knee joint and during continuous passive motion(CPM) treatment and to computationally calculate joint angles at the knee joint dependent on the CPM machine design and its application. Four CPM machines and eleven candidates were recruited for this study. Experimental and numerical studies have been peformed to calculate the range-of-motion of CPM machines. From the experimental measurements, the average range of motions at the knee joint for the CPM machine #1, #2, #3, and #4 were lower than the manufactures suggested values due to improper alignments of the hip and knee joints to the CPM machines. Different design of CPM machine generated different outcomes of the ROM at the knee joints during CPM. The experiments and kinematic simulation in this study could be used to provide useful guidance in the treatment of CPM after joint surgery.
