We treated a 37-year-old male with traumatic hematoma in the suprapatellar bursa that had developed in the form of persistent swelling on suprapatellar area of left knee after blunt trauma. Though there were no obvious abnormal findings on plain roentgenographs, an isolated suprapatellar cystic lesion with fluid-fluid level on T2-weighted sagittal image of MRI was noted. We found the suprapatellar plica with complete septum and no synovitis in the knee joint proper by arthroscopy. We incised the plica and found leakage of blood-stained fluid from the suprapatellar bursa. There were no findings of pigmented villonodular synovitis or other tumorous lesions. At 6 months after surgery, the patient felt symptom-free and there was no recurrence.

Diagnosis of localized pigmented villonodular synovitis (PVNS) is difficult because of its rarity and indistinctive symptoms. This study presented 11 cases of localized PVNS of the knees, which were diagnosed and treated by arthroscopic technique. There were 6 males and 5 females between the age of 15 and 59 years (mean 34.6 years). The interval from the onset of symptoms to treatment ranged from 2 months to 3 years (average 29.9 months). All patients complained knee pain and 7 patients complained palpable mass. Four of the 11 patients had trauma history. The most common involved site was anteromedial synovium near the anterior horn of medial meniscus (5 patients). The remaining cases were identified on anterior fat pad (2 cases), suprapatellar pouch, posteromedial compartment, medial gutter and the anterior horn of the lateral meniscus, respectively. Nine cases had 1 mass and the remaining cases each had 2 or 3 masses. There was no evidence of recurrence during the follow-up period (average 29.9 months). Arthroseopy is effective in the diagnosis of localized PVNS with minimal morbidity and in the definitive treatment for PVNS.

Ganglion cysts have been described in all joints. In the knee, although the finding of meniscal degenerative cysts is fairly common, a few cases have been reported concerning ganglion cysts of anterior cruciate ligament. However, ganglion cysts of posterior cruciate ligament are quite rare. We experienced two cases of ganglion cyst in the posterior cruciate ligament, which were treated successfully with arthroscopic debridement.

The pretibial cyst is a very rare complication after anterior cruciate ligament (ACL) reconstruction. It occurs whatever kind of graft choice or kind of graft fixation method at tibial side. It have been known such as graft necrosis at tibial side, extra-articular leakage of joint fluid through tibial tunnel, foreign body reaction due to breakdown of the bioabsorbable screw and incomplete incorporation of graft to bony tunnel as the cause of pretibial cyst. We experienced one case of pretibial cyst which had undergone ACL reconstruction with autogenous hamstring graft fixed with biodegradable interference screw. We report a rare case of pretibial cyst with literature review.

Purpose: To report the results of arthroscope assisted posterior cruciate ligament reconstruction without tourniquet, which has not yet been reported in documents within the country. Materials and Methods: Out of the 75 cases of arthroscope assisted posterior cruciate ligament reconstruction on patients with posterior cruciate ligament damage from January, 1998 to May,2003 in this hospital, study was done on 49 cases of patients with isolated posterior cruciate ligament damage, excluding 16 cases of patients who were applied tourniquet in extraarticular operation due to combined damage such as in lateral collateral ligament and posterolateral collateral ligament, and 10 cases where the postoperative observation period was less than 12 months. There were 13 cases where reconstruction was done using autogenous bone-patella tendon-bone, 19 cases using allogenous bone-patella tendon-bone, and 17 cases using allogenous achilles tendon. For assessment, the 49 cases were compared using Lysholm knee scoring scale. Results: The average duration of operation was 105 minutes. There were no severe complications such as swelling, bleeding, infection etc . Assessment results attained by Lysholm knee scoring scale was 74(fair) for cases where autogenous bone-patella ten-don-bone was used,75(fair) for cases where allogenous achilles tendon was used, and 76(fair) for cases where allogenous bone-patella tendon-bone was used. Conclusion: There are no difficulties to perform the arthroscopic assisted posterior cruciate ligament reconstruction. Reconstruction without tourniquet can be thought to prevent complications that could follow when using it.

It is reported that approximately 100,000 anteior cruciate ligament (ACL) reconstructions are performed in the United States each year. Recurrent instability because of graft failure is estimated to occur in from 0.7$\%$ to 8$\%$ of reconstruction. Recently revision ACL reconstruction is likely to become more common as the number of primary reconstructions continues to increase. Arthroscopic revision ACL surgery with adequate graft for failed ACL reconstruction was successful in objectively and subjectively improving stability. However, considering the most common causes of failure after ACL reconstruction were errors in surgical technique, it is important that the primary ACL reconstruction should be performed with correct surgical technique. Therefore author reviewed the causes of failure of reconstruction to prevent the failure of reconstruction and described the surgical technique of revision ACL reconstruction.

Purpose: We evaluated the result of the degree of reduction and anterior instability after arthroscopic treatment of tibial spine fractures. Materials and Methods: Thirty-two cases of tibial spine fractures treated with arthroscopic procedure could be evaluated and the mean follow-up period was $18\;(12{\sim}48)$ months. Evaluations included Lachman test, rotatory instability examination and side to side difference (SSD) using KT-2000 arthrometer. The degree of radiologic reduction was classified as accurate reduction, anterior elevation and reduction failure, according to which the degree of anterior instability was measured. Results: There were twenty three cases (71%) of accurate duction, eight cases (25%) of anterior elevation and one case (4%) of education failure. Eight (29%) of twenty eight cases with pull-out method showed anterior elevation. The SSDs of the accurate reduction and the anterior elevation group were 2.0 mm and 2.8 mm, respectively showing no significant difference. However, the percent age of grade 0 Lachman test and SSD less than 3 mm of the accurate reduction group were significantly higher. Conclusion: Accurate reduction is important in reducing anterior instability especially in unstable fractures. Therefore, arthroscopic pull-out method should be performed with great caution to avoid anterior elevation of the fracture fragment.

Osteochondral fracture is common in adolescent and usually occurs in the knee and ankle. Many authors have written concerning osteochondral fracture of the ankle joint, however, many of these pertain only to the talus. The author has found an osteochondral fracture of the articular surface of the medial malleolus within the ankle joint not previously described. We report a case of this lesion that was treated by arthroscopic osteochondral fragment removal.

Avulsion fractures of the intercondylar eminence of the tibia are not uncommon. In the displaced avulsion fracture, anatomical reduction and firm fixation of fracture fragments are needed but the most of the conventional operative techniques including arthroscopic technique are relatively complex and need. The results were not always satisfactory due to the risk of postoperative complications such as wound infection, premature epiphyseal closure and loss of fixation after early motion etc. So we describe a simple and safe modified method of arthroscopic reduction and fixation for avulsion fractures of the intercondylar eminence of the tibia. In our thirteen cases, we achieved anatomical reduction and secure fixation using cannulated screw through the three arthroscopic portals (anterolateral, medial mid-patellar and central). Postoperatively, immediate limited range of motion of the knee and partial weight bearing were possible. Additional use of the washer afforded safe fixation of comminuted avulsion fracture. The advantage of this technique includes its technical simplicity, easy removal of hardware, ability to treat comminuted type IV fracture with washer, no additional skin incision, no damage to growing plate in growth children and less morbidity.
