Objective:To observe the effect of Risedronate on fracture healing in elderly patients with osteoporotic femoral intertrochanteric fracture.Methods:A retrospective case-control study was conducted on elderly patients with osteoporotic femoral intertrochanteric fractures in our hospital from June 2019 to June 2020.They were followed up regularly for 1 year after proximal femoral nail anti-rotation(PFNA)internal fixation.According to whether the patients took Risedronate during hospitalization, the patients were divided into two groups(PFNA internal fixation combined with Risedronate, 39 cases)and control group(PFNA internal fixation alone, 44 cases). The BMD values before and 1 year after operation were compared between the two groups.Harris score was used to evaluate hip function, Rush score was used to evaluate fracture healing, and the operation-related complications, adverse drug reactions and fractures in other parts were recorded.Results:The fractures of all patients healed 12 months after operation.There were no recurrent fractures in both groups during follow-up.The mean bone mineral density(BMD)T value in healthy side hip was(-2.83±0.46)in Risedronate group and(-3.16±0.42)in control group( t=-3.397, P=0.001). Among the total 83 patients, 39 patients in the Risedronate group had no obvious adverse reactions; 1 patient of 44 patients in the control group had obvious upper abdominal pain and discomfort, accompanied by nausea and lack of appetite.These symptoms improved after stopping the drug. Conclusions:Risedronate taken early after surgery does not affect fracture healing and can improve bone mineral density of healthy side hip.

Objective:To explore the clinical outcomes of anatomical double-bundle medial patellofemoral ligament (MPFL) reconstruction with double suture anchor technique in treating patellofemoral instability in adolescent.Methods:Twenty-five young people with patellofemoral instability (25 knees) in our department from January 2013 to December 2014 were enrolled for this study.All patients were performed anatomical double-bundle MPFL reconstruction with arthroscopic-assisted suture anchors technique in the patella,and fixed in the femoral socket with absorbable interference screw.All patients are evaluated by different methods,including patient's satisfaction,patellar apprehension test,recurrent subluxation/dislocation,CT assessment of bone tunnel and patellar tilt angle.Lysholm scores,Tegner scores and Kujala scores were recorded at the final follow-up.Results:The mean follow-up was 24 (range 20-40) months.All cases were observed in negative patellar apprehension test.Infection,recurrent subluxation/dislocation and patellar fracture were not found at the last follow-up.CT results demonstrated that the tunnel position were good.The patellar tilt angle was decreased from 21.6°±2.3° to 10.5°±1.6° (P＜0.05);the Lysholm scores was increased from 51.7±5.3 to 93.8±6.5 (P＜0.05).Tegner scores was increased from 4.1± 1.1 to 5.5±0.6 (P＜0.05).Kujala scores was increased from 53.5±6.4 to 94.6±4.3 (P＜0.05).Conclusion:Arthroscopic-assisted anatomical double-bundle MPFL reconstruction with the suture anchors technique is a safe,minimal invasive and effective surgical option for treating patellofemoral instability in adolescent.

Objective:To explore the effectiveness and safety of pie-crusting the medial collateral ligament release (MCL) in treating posterior horn of medial meniscus (PHMM) tear in tight medial tibiofemoral compartment of knee joint.Methods:Thirty-two consecutive patients with PHMM tear in tight medial tibiofemoral compartment of knee joint were admitted to our department from January,2013 to December,2014.All patients were performed pie-crusting the MCL release at its tibial insertion with 18-gauge intravenous needle.All patients were evaluated by valgus stress test and bilateral valgus stress radiograph at postoperative 1st day,4th week and 12th week.Visual Analogue Scales (VAS),Lysholm scores,Tegner scores and International Knee Documentation Committee (IKDC) scores were recorded at the 1st,3th,6th month follow-up,then follow-up every 6 months.Results:The mean follow-up was 28 (24-36) months.All cases were negative in valgus stress test.MCL rupture,femoral fracture,articular cartilage lesion and neurovascular injury were not found at the last follow-up.The median medial joint space width of affected side and unaffected side for valgus stress radiographs were 6.8 mm and 4.3 mm (P＜0.05) at the 1st day,5.5 mm and 4.2 mm (P＜0.05) in the 4th week and 4.8 mm and 4.3 mm (P＞0.05) at the 12th week,respectively.VAS scores was changed from 4.5±1.5 preoperatively to 1.7±1.0 at the final follow-up (t=16.561,P＜0.05).Lysholm scores was changed from 52.3±5.8 preoperatively to 93.2±6.3 at the final followup (t=-41.353,P＜0.05).Tegner scores was changed from 4.1±1.1 preoperatively to 5.5±0.6 at the final follow-up (t=-18.792,P＜0.05).IKDC scores was changed from 54.5±6.2 preoperative to 93.8±4.5 at the final follow-up (t=-38.253,P＜0.05).Conclusion:Pie-crusting the medial collateral ligament release is a safe,minimal invasive and effective surgical option for posterior horn of medial meniscus tear in tight medial tibiofemoral compartment of knee joint.
