It is not infrequent to observe the reeurrence of the Bakers cyst. Recurrence of the cystic lesions are more frequent in wide based type than in pedicle type due to difficult ,identification and inadequate eradication of the cyst wall. We injected methylene blue into the cyst after aspiration of the fluid. Blue stained wall enables the surgeons to idendify the whole inner surface of the cyst, and lessens the chance of missing a portion of it. We could reduce the recurrence rate near to zero percent after adopting this technique upto now. Broad based type is more prone to recurr and the whole recurred five cases were belong to this type.

In traumatic knee dislocation, vascular injury is one of the most serious complication. After pertinent management of acute vascular problems, we should take care of the ligamentous injury involving both the ACL and PCL which are the main causes of knee instability, and consequent traumatic degenerative changes. No standard technique of reconstruction has been reported concerning these ligamentous injuries up to now as far as we know. Authors tried a new management which reconstruction was done simultaneously on both the ACL and PCL injuries. Bone-Achilles tendon autograft was used as PCL substitute in all the cases, and which turned out to be a very efficient one for the control of anterior-posterior displasement as well as rotary instability. Bone-patellar tendon-bone autograft or bone-Achilles tendon autograft was good for the reconstruction of the ACL bone-patellar tendon-bone in two cases, bone-Achilles tendon in two cases, and semitendinosus tendon also in two cases. After 6 months of operation, all the patient returned to the previous level of walking without crutches. This management showed outstanding results in terms of knee stability and subjective symptoms.

One hundred and forty eight cases of tennis elbow were treated by conservative managements firstly such as rest, medication, immobilization, physical therapy and/or local steroid injection, from Jan. 1985 to Jun. 1994 at Department of Orthopaedic Surgery, National Medical Center. Among the 148 cases, 16 cases who failed conservative managements, were treated with Nirschl & Pettrone operation. The results were summarized as follows, 1. Among the 148 cases, 110 cases(74%) were female, and 61 cases(41.2%) were in the age group 41 to 50 years old, and mean age was 42.3 years old. 2. Ninty nine cases were housewives and only 15 cases were related to sports. 3. The conservative results of one hundred and sixteen patients were graded excellent and good; and of thirty two patients, fair and failure. 4. The operative results of seven patients were graded excellent; of three, good; of four, fair; and of two, failed. 5. Recurence was developed in 18 cases(12.2%), and we obtained excellent and good result in 17 cases with both conservative and operative treatment. Above results suggest that the term, tennis elbow is a misnomer because it occurs more commonly in non-athletes such as housewives than in tennis players. So it seems to be an occupational disease rather that sports injury. Now, we propose to eliminate of the term of tennis elbow and to substitude with new terminology that describes the true understanding and therapeutic orientation of it.

Although the incidence of leprosy is decreased considerably, the deformity and disability of it is serioues. In the hand, combined median and ulnar nerve affection is most common, and it leads to many problems including opposition dysfunction and claw hand deformity. And opposition dysfunction is most significant disability in the hand function, so its correction or reconstruction is mandatory We performed 20 cases of opponensplasty from Oct. 91 to Apr. 94 at National Medical Center, and analyzed its results according to new assessment criteria invented by authors, and evaluated the efficacy of the operative treatments. The results were as follows: 1. The patients were 9 males and 11 females, average age was 48 years old, and average duration of paralysis was 28 years. The mean follow-up period was 2.8 years. And most common type of nerve affection was combined low median and high ulnar nerves. 2. We performed 18 cases of Burkhalter opponensplasty using extensor indicis proprius and 2 cases of Riordan opponensplasty using ring finger sublimis at the leprosy hands. 3. According to authors assessment criteria for leprosy hand, the result of operative treatment was excellent in two, good in ten, fair in seven, and poor in two patients. So we obtained more than good results in 50% patients. 4. We could obtain good result with Burkhalter opponensplasty in leprosy hand, especially when combined with proper preoperative physical therapy and adjuvant operation for release of contracture and joint stiffness.
