ABSTRACT
Objective To evaluate the skill and outcome of arthroscopic reconstruction of posterior cruciate ligament (PCL) with retention of PCL remnant. Methods From April 2004 to June 2006, 38 patients (38 knees) with PCL deficiency were verified by clinical and arthroscopic examinations. Of them, there were 9 knees combined with disruption of the posterolateral comer, 6 with rupture of the posteromedial corner, 8 with lateral meniscus tear and 4 with medial meniscus tear. With reservation of PCL remnant and synovium, all the impaired PCLs were reconstructed with single bundle of autogenous quadrupled hamstring tendons under arthroscopy. Interference screws were used for direct anatomic fixation of the reconstructed ligament. Results No severe comphcations occurred at early stage after operation in all 38 patients who were followed up for 12-37 months (average 20.79 months). Lysholm score was improved significandy from 40-70 points (mean 51.32 pints) before operation to 70-100 pints (mean 92.37 points) at the latest follow up (t=-30.14, P<0.01). According to International Knee Documentation Committee (IKDC) score, there was a remarkable improvement from 16 abnormal knees (grade C) and 22 severely abnormal knees (grade D) preoperatively to 18 normal knees ( grade A), 18 nearly normal knees (grade B) and 2 abnormal knees at the latest follow up (Z=-6.00, P <0.01). Of 38 patients, 36 returned to normal sports level but 2 degraded level of sports. Conclusions Arthroscopic PCL reconstruction with retention of PCL remnants is a feasible technique, with satisfactory outcome. Preservation of PCL remnants and synovium may be beneficial to biological incorporation and reinnervation of the reconstructed ligament.
ABSTRACT
[Objective]To observe the curative effect of ectogenic bone inductive factor in treating osteoporotic frature,and provide feasibility pathway and method for clinical treatment.[Method]Sixty cases of osteoporotic fracture from Febuary 2002 to May 2005 were randomly divided into experimental group(30 cases) and control group(30 cases).The experimental group were given 4 ml osteotide a day by intramuscular injection,and 15 days were a course of treatment.The second course of treatment went on after 15 days later when the first course ended.At the same time,no any medicine was given to the control group.The biochemical indicators were detected 2 months later.And after 2,4 and 6 months the union of fracture was observed through radiology.[Result]Four months after operation,radiology examination showed that the rate of union of fracture was 93% and 67% respectively.There was significant difference between the two groups(P
ABSTRACT
[Objective]To evaluate the technique and outcome of arthroscopic reconstruction of anterior cruciate ligament (ACL) with preservation of the remnents.[Method]From June 2005 to May 2006, 28 knees with ACL tear in 28 patients were verified with arthroscopy in this department.Of them,8 knee were combined with lateral meniscus tear and 6 combined with medial meniscus tear. All the damaged ACLs were reconstructed with single bundle of autogenous quadrupled hamstring tendons under arthroscopy without remove of the remnants of ACL. Bioabsorbable interference screw was used for direct anatomic fixation of the reconstructed ligament.[Result]No severe complication occurred in early stage after operation in the 28 patients.All of them were followed up for 12 to 24 months with an average of 18 months. Lysholm score was remarkablely improved from 46～80 (mean 60.75?9.54) preoperatively to 85～100 (mean 95.89?6.24) at the latest follow up (P
ABSTRACT
Objective: To discuss the clinical effect of the treatment of metaphyseal cancellous bone fracture with fragment fixation system implants(FFS).Methods:Thirty patients treated with FFS were reviewed.Results:The patients were followed up for 7～ 24 months (8.7 months in average).The fractures in all cases were healed in 6 months and the function recovered or nearly reeovered. Conclusion:By traction with FFS to treat this kind of fracture,the fractures and joint function recovered.The operation is simple and trauma is little.
