The results of unicompartmental knee arthroplasty are still controversial. The purpose of this study is to evaluate the clinical results of three different component systems of unicompartmental knee arthroplasties. From December 1982 to January 1996, 106 unicompartmental knee arthroplasties were performed. There were 13 Modular II(group I), 47 Microloc(group II) and 46 Allegretto(group III) unicompartmental knee arthroplasties. Average follow-up period was 7 years 1 month. At the last follow-up, average knee score of Hospital for Special Surgery(HSS) was 92 points and average tibiofemoral angle was valgus 3.5 degrees. Among three groups, there was no significant difference in knee score of HSS and tibiofemoral angle. Twelve knees(11%) in all three groups have required revision. The causes of revision were six implant wears(all in group II), five implant loosenings(one in group I and four in group III) and one deep infection(in group II). In conclusion, the results of unicompartmental knee arthroplasty at average 7.1 years follow-up period were satisfactory. High incidence of insert wear in Microloc unicompartmental knee arthroplasty(group II) might be due to thin polyethylene insert supported by metal backed tibial tray.

The suprapatellar plica is a remnant of the embryonic septum separating the suprapatellar pouch from the knee joint. Complete type of suprapatellar plica is rarely reported and its clinlical significance is controversial. The purpose of this study is to verify the complete type of suprapatellar plica as an important cause of anterior knee pain and to evaluate the clinical results after arthroscopic excisien of it. From September 1991 to April 1997, we studied prospectively 54 patients, 90 knees which were diagnosed as cornplete type of suprapatellar plica preoperatively. The mean age was 32 years (15-57 years) and sex distribution was 14 males and 40 females. For the preoperative diagnosis, we checked clinical symptom, past history, physical finding and plain X-ray routinely and performed bone scan, double contrast arthrogram and MRI, if necessary. All patients complained vague anterior knee pain at standing, sitting, stair climbing and exercise for long times. All 90 knees were examined arthroscopically. Among them, 80 knees had complete type of suprapatellar plica and remaining 10 knees had other findings. After all, positive predictive value of preoperative diagnosis for complete type of suprapatellar plica was 89%. Among 36 patients diagnosed as bilateral preoperatively, 33 patients(92%) were confirmed as bilateral in arthroscopic examination. After arthroscopic excision of plica, clinical results were total relief of pain in 19 knees(24%), improvement in 55 knees(69%), no change in 6 knees(7%) and none of worsening. In conclusion, complete type of suprapatellar plica should be considered as an important cause of anterior knee pain especially which is vague, intermittent and bilateral.

Ligament injuries of the knee joint are very common among competitive athletes. Acrurate assessment ot the nature of these injuries is a prerequisite for appropriate therapy. The purpose of this study is to evaluate the significance of MRI findings in assesing the status of ACL tear and associated injuries. 31 cases of ACL injuries were examined and reconstructed arthroscopically from Jan. 1997 to Sep. 1997 at Kyung Hee University Hospital. 1n all cases, we reviewed preoperative physical and MRI findings and performed postoperative radiologic assessments. Results were as follows; 1. Lachman test and Pivot shift test were positive in all 31 cases but anterior drawer test was positive in 29 case,s. 2. In MRI findings, 24 cases were interpretated as complete ACL tear and / cases as inccomplete ACL tear. But these 7 cases were confirmed as complete tear in mthroscopic exanunation with careful probing of ACL fiher. 3. MRI showed associated meniscal injuries in 19 cases(61%)-14 cases(74%) at medial meniscus, 5 cases(26%) at lateral meniscus. All cases were confirmed arthroscopically. In conc1usion, physical findings are more reliable than MRI findings in diagnosing the complete ACL tear and deciding the ACL reconstruction. But MRI findings are very helpful to assess the associated injuries and plan the treatments.

In the classical ballet dancers, ankle joints are frequently overused. Especially the Pointe and the Releve are the two basic steps of ballet dance which cause the narrowing of the posterior aspect of the ankle joint. Posterior impingement syndrome of the ankle joint is defined as impingement occuring at the anatomical interval between the posterior tibial articular surface and os calcis. The purpose of this study is to describe the anatomy and etiology of this injury and to review the non-operative and operative treatments. Sixteen cases of posterior impingment syndrome had been treated between March 1994 and March 1995. Ten dancers were professional and six were students. The patients was divided 3groups by etiologic factor. Group 1 is anatomical problem factor, Group 2 is overuse factor and Group 3 is ankle sprain factor. Thirteen dancers (81.2%) improved with conservative treatment including local steroid injection. Among the other three dancers, operation was performed in one case. The other two cases stopped dancing. The result was good in one dancer after operation. In the classic ballet dancers, posrerior impingement syndrome was frequent disorder and major etiologic factors are anatomical problem and overuse. Operation was necessary in only group l. It is good result in conservative treatment and operation.

We measured fasting Serum Angiotensin-Converting Enzyme (SACE) in 100 healthy controls and 75 coal worker's pneumoconiosis (CWP) patients by a commercial kits (ACEcolor®, Fujirio Inc., Japan) and evaluated this manual method. The linear range extends to an activity of 80U/L. Precision on a commercial control serum (ACE control-N®, Sigma Co.) with a mean value of 9.47U/L yielded a within-run and between-run CVs are 5.6% (N=15) and 6.9% (N=14) respectively. Save in 75 CWP was 20.3±5.7U/L (mean±s.d.); higher than in healthy controls (13.4±3.9U/L, P<0.01). No correlation was found between SACE, sex, and age. The results suggest that the measurement for SACE and follow-up SACE in coal workers may be a useful diagnostic tools for CWP.
