ABSTRACT
Objective To study the effectiveness,side effects and safety of glucosamine chondroitin sulfate calcium (Keylid(R)) tablets for osteoarthritis of the knee.Methods To review the clinical data of 103 cases of primary knee osteoarthritis who had been treated between March 2013 and February 2014.The intervention group included 53 cases (23 males and 30 females with an age of 71.0 ± 9.1 years) who received Keylid(R) tablets (2 tablets twice per day) accompanied with exercise therapy for 24 weeks;the control group included 50 cases (22 males and 28 females with an age of 69.8 ± 8.8 years) who received placebo (2 tablets twice per day) accompanied with exercise therapy for 24 weeks.No NSAIDs,calcium or other articular dietary supplements were taken by the 2 groups during the study period.T-test was used to analyse the results.Results After treatment,the range of knee motion for the intervention group (123.27° ± 10.22°) was significantly larger than that for the control group (116.34° ± 8.76°),and the average pain visual analogue score after 40 m walking for the former (2.92 ± 0.36) significantly lower than that for the latter (3.30 ± 0.22) (P ＜ 0.05).There were no significant differences between the 2 groups in Western Ontario and McMaster Universities Arthritis Index,time for 40 m walking or circumference of the knee (P ＞ 0.05).No side effects were observed in either group during the study period.Conclusion Keylid(R) tablets complemented with exercise therapy may reduce pain and improve knee function with no adverse events in the patients with knee osteoarthritis.
ABSTRACT
Objective To evaluate the surgical technique and clinical significance of the therapy for ankle soft tissue defect with 2 different flee perforator flaps.Methods Twenty-five cases of ankle soft tissue defect with exposed bone of the ankle were involved in this study from August 2006 to April 2012.and the wound sizes varied from 4.0 cm × 5.5 cm to 11.0 cm × 23.0 cm.Twenty cases with acrotarsium soft tissue defect were repaired by free anterolateral thigh perforator flap,five cases with pelma soft tissue defect were repaired by free saphenous artery perforator flap.Results All Twenty-five flaps survived.At 3 to 50 months follow-up [on an average of (18.0 ± 0.8) months] postoperatively,appearance of the flaps was satisfactory,with 10 to 22 mm in 2-PD,and the sensation percentage beyond S2+ was 13/20 cases and 5/5 cases at 3 months follow-up,respectively.Conclusion The optimal therapy for the acrotarsium soft tissue defect is the free perforator anterolateral thigh flap,and free saphenous artery perforator flap should be used for pelma soft tissue defect.Avoid secondary orthopaedic surgery,pay more attention to the donor site of the flap.VSD can significantly promoting the survival rates of the free perforator flaps if the soft defects are caused by open injury.
