RESUMO
Objective To measure the scope of normal meniscus by magnetic resonance imaging(MRI),and create a database of meniscus size of each part.Methods The MRI image measured rake angle and back angle,body height and width of each part and the angular distance of rake and back angle of 303 meniscus of normal knee joint.Results The width and height of anterior horn,anterior exterior angle,body,angulus posteriolateralis and back angle of the medial meniscus were (5.67 ± 1.37) mm and (3.53 ± 0.86) mm,(7.24 ± 1.91) mm and (4.38 ±1.01) mm,(5.61 ± 1.73)mm and (4.25 ±1.07) mm,(11.01 ±3.53) mm and (5.41 ± 1.66)mm,(9.21 ±2.71)mm and (5.02 ± 1.39)mm,respectively.Rake and back angle of angular distance was (38.51 ± 10.88)mm.The width and height of the anterior horn,anterior exterior angle,body,angulus posteriolateralis and back angle of the lateral meniscus were (6.95 ± 1.69) mm and (3.83 ± 0.91) mm,(7.48±1.90)mmand (4.06 ± 0.97) mm,(6.51± 1.79) mm and (5.10±1.01)mm,(7.62±1.99)mm and (5.18±1.19)mm,(6.68 ± 1.41) mm and (5.64 ± 1.12) mm,respectively.The rake and back angle of angular distance was (38.51 ± 10.88) mm.Conclusion In this study,we obtained the data of meniscus for normal people by MRI,which provides reference values for diagnosis of meniscus injury and transplantation.
RESUMO
BACKGROUND:Kidney-tonifying herbs have been reported to promote tendon-bone healing in rabbits after anterior cruciate ligament reconstruction (ACLR). OBJECTIVE:To verify the effects of kidney-tonifying herbs on tendon-bone healing after ACLR. METHODS:Seventy patients with anterior cruciate ligament injury undergoing ACLR were randomly assigned to study group (administration of Liuwei dihuang pil s+celecoxib) and control group (administration of celecoxib alone). Preoperative, postoperative 6-and 12-month assessments of patients by the Lysholm Knee Scoring Scale, International Knee Documentation Committee (IKDC) Subjective Knee Form and MRI imaging were performed. RESULTS AND CONCLUSION:Postoperative Lysholm scores were significantly increased compared with preoperation in the study and control groups (P<0.05), and the scores of sections stair-climbing and instability and total scores of the Lysholm Knee Scoring Scale in the study group were superior to those in the control group (P<0.05). Postoperative IKDC scores were significantly increased compared with pre-operation in the study and control groups (P<0.05), and the scores of section flaccid leg and subjective function and total scores of the IKDC in the study group were superior to the control group (P<0.05). The enlargement rate of middle and proximal parts of grafts was significantly increased in the study group compared with the control group 6 months postoperatively (P<0.05), and the enlargement rate of middle and distal parts of grafts was significantly increased in the study group compared with the control group 12 months postoperatively (P<0.05). The tibial and femoral tunnel enlargement was observed in both groups at 6 and 12 months postoperatively (P<0.05). The enlargement rate of the tibial tunnel was significantly decreased in the study group compared with in the control group (P<0.05). The signal-noise ratio of the femoral end and middle part of grafts in the study group was significantly higher than that in the control group 6 months postoperatively (P<0.01). In contrast, the signal-noise ratio of the femoral end and middle part of grafts in the study group was significantly lower than that in the control group 12 months postoperatively (P<0.05). Our results indicate that kidney-tonifying herbs can improve the tendon-bone healing after ACLR.
RESUMO
ObjectiveTo observe the clinical efficacy of external application of sihuang-honey for aseptic inflammation after total knee arthroplasty.Methods 30 cases of total knee arthroplasty patients were recruited into two groups,of 15 cases in each group.The treatment group was treated with sihuang-honey (made of rhubarb,scutellaria,phellodendron,coptis according to the same proportion of powder with honey ),which was placed on a sterile plastic sheet,0.5 cm thickness.The sheet was applied on the knee of the highest skin temperature for 6 hours,removed it for 2 hours interval,and reapplied on it,for altogether 24 hours before changing another sheet.The control group were treated by continued covering ice on the knee every day,with the ice completely surrounded the knee.Both groups were treated for 2 weeks.Clinical efficacy was observed before the treatment,and 3 d,7 d,14 d after the treatment.ResultsAfter the treatment,compared with the control group,the treatment group was effective in terms of VAS score (4.12± 1.08) points in 3d,(3.34±0.61)points in the first 7 days; skin temperature (37.56±0.40) ℃,activity (98.56±3.24) ° in 3d,and the difference was statistically significant (P＜0.05).The degree of swelling in 3 d (5.80±2.00) ％,7 d (9.33±2.55)％,14 d (12.13 ± 2.70)％ in the treatment group were better than the control group (P＜0.05); The rate of pain relief of treatment group was 93.33％ and satisfaction was 66.67％,although better than 86.67％ and 46.67％ of the control group,the difference was not statistically significant (x2 were 1.33,3.04,P＞0.05).Conclusion Sihuang-honey was effective for the treatment of aseptic inflammation after the surgery of total knee arthroplasty.
