ABSTRACT
Intraarticular ganglion of the knee joint is a cystic mass found around cruciate ligaments in infrapatellar fat pad or under patellar tendon. The first report on intraarticular ganglion of the knee joint along with some intermittent case reports or ganglion around the cruciate ligaments were in 1924 by Caan. Ganglion under the patellar tendon or in the patellar fat pad was first reported in 1972 by Muckle and Monahan. The two cases were treated with open arthotomy and mass excision. There was been no report on ganglion under patellar tendon since then. We managed two cases of ganglion under the patellar tendon with arthroscopic debridement. After 16 months of treatment, there has no recurrence of symptom. We report two cases of ganglion under patellar tendon with the review of the literature.

Anomalies of the lumbosacral nerve roots, in which conjoined nerve roots are most common, are occasionally accompanied by herniated nucleus pulposus. Most of these anomalies were incidental findings from operations, and recent advances in diagnostic imaging techniques have increased the number of cases of lumbosacral root anomalies reported. All these anomalies are congenital, unilateral and almost exclusively situated at the L5-S1 segment. Diagnostic techniques, such as myelography, CT and MRI detect conjoined nerve root. Conjoined nerve root may be confused with a dumbbell tumor or extruded free disc fragment on CT scans. Surrounded by high-signal intensity epidural fat, a conjoined nerve root is more clearly depicted on MR images than on CT scans. Although the size of disc herniation was small, the symptom was magnified by a relatively fixed conjoined root. At surgery, it is necessary for a larger surgical exposure by means of hemi-laminectomy because of the fixation of the nerve roots, and difficulty in retraction. Recently, we experienced two cases of conjoined nerve root and presented them with a review of the literature.

From June 1994 to December 1995, we perfoimed arthroscopic anterior cruciate ligament reconstruction using B-T-B alIograft in nineteen patients and postoperative aggressive rehabilitation program including early range of motion (ROM) exercise and muscle strengthening exercises in all cases. Except six cases of loss of follow-up, thirteen cases were analyzed. Postoperative results were evaluated by Lysholm knee score and M?ler s criteria at average 14 months (range from 6months to 24 moths). The average Lysholm score improved from 56 to 79. According to the Miijer s criteria, the results were excellent in 7 cases, good in 5 cases and fair in 1 case. We concluded that the reconstruction of the anterior cruciate ligament using B-T-B allograft could be an effective method with many benefits in treatment of anterior cruciate ligament rupture and that the results using B-T-B allograft was as good as those using autograft. But, further evaluation and long teim follow-up should be needed.
