Patellofemoral complications are the most frequent problems in total knee arthroplasty. In the literature, the subject of patella resurfacing and nonresurfacing is controversial. Twenty-seven osteoarthritic patients who received bilateral total knee prostheses were studied to evaluate the advantages and disadvantages of patella resurfacing prospectively. Only patients with mild patellofemoral disease were included in the study. The Ortholoc modular implant was used in all cases. Cementless femoral and tibial component were used. But, if we resurfaced the patella, cement was used. In all patients, patella resurfacing had been done in the left knee but not in the right knee. For the clinical analysis, We used Knee Rating Score of the Hospital for Special Surgery(HSS), For the roentgenographic analysis, We used Laurin's lateral patellofemoral angle & Merchant's congruence angle. In the follow up, blind test for patellar pain was performed to compare between right and left knee joint clinically. The average age was 61 years(range 28-72 years) and the average follow up was 21 months(range 12-27 months). Preoperative ROM was 104.4 degrees in right side and 106.7 degrees in left side. Postoperative ROM was 112.7 degrees in right side and 109.6 degrees in left side. Preoperative HSS Knee Rating Score was 53.1 point in right side and 54.8 point in left side. Postoperative HSS Knee Rating Score was 81.5 point in right side and 81.2 point in left side. In the plain knee AP view, preoperative tibiofemoral angle was varus 7.0 degrees in right side and varus 5.6 degrees in left side. Postoperative tibiofemoral angle was valgus 5.1 degrees in right side and valgus 4.9 degrees in left side. Preoperative Merchant's congruence angle was 14.9 degrees in right side and 15.3 degrees in left side. Postoperative Merchant's congruence angle was

We evaluated the degree of ptosis, the function of levator muscle, and postoperative interval to recovery of ptosis in 20 patients who underwent scleral buckling for retinal detachment. The MRD 1(Margin reflex distance 1), function of levator muscle by Berke method and interpalpebral fissure height were evaluated at preoperative day and 1, 3 days, 1, 2, 4, 6, 8, weeks, and 6 months after surgery. The results were compared according to age, gender, extent of buckling, location of buckle. All patients were reported to develop ptosis at postoperative day one, and 20% of them showed mild ptosis persistent until 8 weeks after surgery. The decrement of MRD 1 was statistically significant until postoperative 2 weeks, but impaired function of levator muscle was statistically significant until postoperative 6 weeks(P<0.05). The postoperative interval to recovery of MRD 1 was delayed in group of old age(order than 40 years), in male and when the buckle was located under the superior rectus muscle(P<0.05). The postoperative interval to recovery of function of levator muscle was delayed in group of female, when the buckle extent was more than 180 degrees and when the buckle was located under the superior rectus muscle(P<0.05).

PURPOSE: In this study we analyzed and compared the orbital anatomy in Korean and Caucasian subjects using computed tomography (CT) measurements. METHODS: Two observers performed a cross-sectional, retrospective analysis of 44 CT scans of subjects (22 Koreans, 22 Caucasians) with no appreciable orbital or globe disease. Ten length measurements and 3 angle measurements of various orbital aspects were obtained. Analysis was performed to determine if changes in these parameters were associated with race. RESULTS: Anterior medial interorbital length was 24.05 +/- 2.00 mm in Korean and 21.96 +/- 1.96 mm in Caucasian subjects. Anterior vertical orbital length was 34.19 +/- 1.67 mm in Korean and 35.03 +/- 1.18 mm in Caucasian subjects. The anterior medial interorbital length and anterior vertical orbital length (p < 0.05) were significantly different. Interorbital angle was 47.69degrees +/- 1.49degrees in Korean and 46.15degrees +/- 2.19degrees in Caucasian subjects; the difference was statistically significant (p < 0.05). CONCLUSIONS: Compared with Caucasians, the orbit of Korean subjects has a narrower orbital opening and longer interorbital distance. The present study regarding the anatomy of Korean and Caucasian orbits will assist physicians with the evaluation and treatment of orbital diseases.

In glaucoma patients, optic nerve head analysis is very useful in early detection and progression during follow-up. Among optic nerve head analysis methods, the confocal laser tomographic scanner(Heidelberg Retina Tomograph: HRT) is actively studied for accurate and highly reproducible analysis.We analyzed the optic nerve head of 62 normal eyes(male 40 eyes, female 22 eyes) in third decade of Korean with HRT, and calculated the mean value of each parameters in HRT and evaluated the difference between men and women. We also studied the distribution fo the value of each parameter in normal third decade of Korean. In addition, for the parameters of Rim/Disc area ratio, we calculated the mean value in 6 divisions of optic nerve head.The mean value of Disc area was 2.039mm3, Cup area 0.593mm3, rim area 1.716mm3 and Cup/Disc area ratio 0.237. Rim volume, Maximal cup depth, Height variation contour, Mean retinal nerve fiber layer thickness, and Retinal nerve fiber layer cross sectional area were statistically different between men and women. For Rim/Disc area ratio, the maximal value was noted in nasal inferior(0.873) region, and the minimal value was in temporal(0.579) region. There was no statistically difference between men and women in Rim/Disc area ratio.

PURPOSE: A wide variety of surgical materials have been used for blepharoptosis such as catgut, silicone, 4-0 nylon polyfilament cable-type ophthalmic suture (Supramid(R)), autogenous tendon (palmaris longus),banked sclera, dura mater, fascia lata, and temporalis fascia. The aim of this study was to evaluate the effect of frontalis suspensory surgery with temporalis fascia. METHODS: The authors studied 91 frontalis slings (71 patients) performed from 1993 to 1999 at our hospital for repair of blepharoptosis. Results with temporalis fascia (group A) as the suspensory material were compared to those with autogenous (group B) and preserved (group C) fascia lata. RESULTS: The success rates of group A (31 lids 21 patients), group B (28 lids 24 patients), group C (32lids 26 patients) were 80.6%, 75%, 78.1% respectively. But there was no statistically significant difference in each groups (P>0.05). CONCLUSIONS: We concluded that temporalis fascia for frontalis sling could be used as suspensory material successfully. Moreover, long term and further evaluations must be considered.
