Background:
The purpose of this study was to evaluate the effect of patellar facet angle on pre- and postoperative patellofemoral alignment and the progress of arthritis of the patellofemoral joint in posterior-stabilized total knee arthroplasty (PS TKA) without patellar resurfacing.
Methods:
Patients who had a PS TKA for a varus osteoarthritic knee who were followed up for more than 2 years were included in this study. The radiologic and clinical outcomes were compared between 72 knees (group A) whose patellar facet angle was greater than 126° (> 126°) and 32 knees (group B) whose patellar facet angle was smaller than or equal to 126° (≤ 126°). For the radiologic assessment, the Kellgren-Lawrence grade, mechanical femorotibial angle, Insall-Salvati ratio, patellar tilt angle, patellar displacement and the osteosclerosis of the patellar ridge were evaluated. The range of motion (ROM) and patient-reported outcomes (the Knee Society knee score, the Knee Society function score, the Feller patellar score, and the Kujala patellofemoral score) were used for the clinical assessment.
Results:
The preoperative patellar tilt angle was 9.8° (standard deviation [SD] 5.5) and 14.6° (SD 4.1) in group A and group B, respectively, a significant difference (p < 0.001). Other preoperative radiologic parameters and preoperative patient-reported outcomes and ROM showed no significant difference between the two groups (all parameters (p> 0.05). At the last-follow-up, 22 knees (30.6%) showed progression of osteosclerosis of the patellar ridge in group A and 13 knees (40.6%) showed progression of osteosclerosis in group B (p = 0.371). The postoperative radiologic and clinical outcomes showed no significant difference between the two groups (all parameters,p > 0.05).
Conclusions
Although a narrow patellar facet angle was related to an increase of lateral tilting of the patella, it showed no impact on the preoperative clinical assessment. The radiologic and clinical outcomes evaluated after the PS TKA showed no statistical difference according to the patellar shape. Although the patellar shape evaluated by the patellar facet angle can partially affect the preoperative patellofemoral alignment, this study result indicated insignificant clinical relevance of the patellar shape in the PS TKA.

The authors attempted to analyse the factors influencing the mortality involved in aneurysm surgery based on 38 cases of intracranial surgery for anterior communicating aneurysms, and obtained the following conclusion. 1. The surgical results are much better when the aneurysm surgery is delayed over one week after the occurrence of aneurysmal rupture, if there is no evidence of intracerebral hematoma. Administration of a massive dosage of epsilon aminocaproic acid in the waiting period prior to aneurysm surgery seems to be effective for preventing recurrence of bleeding from the aneurysm. 2. The direction of the anterior communicating aneurysm should be clearly visualized on a cerebral angiogram so that the most effective aneurysmal approach can be selected in surgery. 3. Microsurgery and hypotension in aneurysm surgery minimize brain damage in the exposure of aneurysm and provide accurate isolation of the aneurismal neck from the parent vessel in aneurysmal neck ligation. 4. Proximal ligation of the anterior cerebral artery is also an effective procedure to prevent recurrent hemorrhage from anterior communicating aneurysm.

PURPOSE: Non-Hodgkins lymphoma (NHL) is recognized as not a single disease but a group of diseases heterogeneous in biology and clinical characteristics. Recently, a new pathologic classification system, the REAL classification, has been introduced into the clinic. Although REAL classification has tried to define the subtypes biologically more correctly, its clinical usefulness has not been established yet. A retrospective study was performed to define the clinical characteristics of Korean NHLs according to the REAL classification and to determine its clinical usefulness. MATERIALS AND METHODS: Pathologies of NHLs managed at 3 major hospitals in Korea between 1989 and 1995 were reviewed with immunophenotyping to determine the pathologic subtypes according to REAL classification. Clinical characteristics at the presentation and treatment outcomes of the eligible patients were analyzed. To determine the differences from the NHLs in the western countries, data of Non-Hodgkins Lymphoma Classification Project (NHLCP) were also compared. RESULTS: Total 802 cases were eligible for this study. Although it was similar to NHLCP study that B-cell subtypes were the majority and diffuse large B-cell lymphoma was the most common subtype, the proportion of T-cell subtypes were much higher in our patient population than in the western population. It was because peripheral T-cell lymphomas, angiocentric lymphoma in particular, were more common and follicular lymphomas were less common in our patients. Eleven common pathologic subtypes could be classified into 3 prognostic groups. Marginal zone B-cell lymphoma and lymphoplasmacytoid lymphoma of which 5-year overall survival rate (5-yOSR) were > 80% were classified in the good prognostic group. Precursor T-lymphoblastic lymphoma was classified in the poor prognostic group because its 5-yOSR was less than 30%. The other 9 subtypes were classified in the intermediate prognostic group with S-yOSR of 30-79%. CONCLUSION: The clinical. character' tics and prognoses of Korean NHLs could be defined according to REAL classification. These information would be helpful for the clinicians in formulating treatment strategies of Korean NHLs according to REAL classification.
