Objective To explore the technique of arthroscopic treatment of local ized pigmented villonodular synovitis of the knee and to evaluate its cl inical results. Methods From February to December 2006, 22 cases of local ized pigmented villonodular synovitis of the knee were treated by arthroscopic excision of the focus and partial synovectomy. There were 8 males and 14 females, with an average age of 24 years old (16 to 35 years old). Eight patients had a trauma history, the others had no obvious inducement. The disease course was from 1 month to 30 months with an average of 10 months. The Lysholm score was 68.5 ± 8.2, and the International Knee Documentation Committee (IKDC) score was 72.7 ± 5.2 before operation. MRI showed that 20 knees had definite focuses and 2 had no ones. In all the cases, routine arthroscopic approach combined with assistant approach adjacent to the focus was used. Results All the patients were diagnosed as having local ized pigmented villonodular synovitis of the knee by pathological examination. The incisions healed at stage I. No compl ications occurred after operation. All patients were followed up 18-28 months (average 22 months). The angle of genuflex was less than 90° in 2 cases after 6 weeks, and the range of motion of the knee was recovery after manipulation release. At last followup, MRI showed no recurrence was found in 19 patients. The IKDC score was 92.8 ± 2.4, and the Lysholm score was 94.5 ± 3.5, respectively, indicating significant differences when compered with before operation (P lt; 0.01). Conclusion Local ized pigmented villonodular synovitis of the knee can be effectively treated by arthroscopic excision of the focus along with a rim of surrounding healthy synovium with most minimal invasive and best knee function.
Objective To assess the feasibility, safety, and validity of the TC-Dynamic posterior stabilized prosthesis implanted in the total knee arthroplasty (TKA). Methods Twelve knees of 10 patients (the TC-Dynamic group) were followed up, who had been implanted with the TC-Dynamic posterior stabilized prosthesis from September 2003 to March 2004. Preoperative KSS knee scores were 16.08±11.58, function scores 13.75±19.79, and the range of motion (ROM) of the knee 75.00±26.46°. Meanwhile, 50 knees of 30 patients (the Scorpio group) werefollowed up, who had undergone TKA with the Scorpio posterior stabilized prosthesis.Preoperative KSS knee scores were 19.48±967, function scores 3.16±19.82,andthe ROM of the knee 80.80±22.82°. The anteroposterior and lateral X-ray filmsof each knee were examined before and after operation. The statistical Z-test was used to analyze the differences between the 2 groups in the improvement of the KSS knee scores, function scores, and ROM after operation. Results The average of the 130 days’ follow-up revealed that the patients implanted with the TC-Dynamic prosthesis had an excellent result. In the TC-Dynamic group, the KSS knee scores were 88.83±4.04 with improved scores of 72.75±14.47 compared with those before operation; function scores were 79.17±5.15 with improved scores of 65.42±19.47; the ROM of the knee was 107.92±11.57° with increased degrees of 32.92±32.22°.Meanwhile, in the Scorpio group, the KSS knee scores were 85.68±7.36 with improved scores of 66.20±10.44 compared with those before operation; function scores were 71.40±12.70 with improved scores of 68.24±25.35; the ROM of the knee was 109.20±11.13° withincreaseddegrees of 28.40±26.41°.There was no significant difference in the improvement of the KSS knee scores, function scores, and ROM after operation between the 2 groups （Pgt;0.01）. All the X-ray films of the knees implanted with both the Scorpio prosthesis and the TC-Dynamic prosthesis were analyzed.No malalignment or lucent line with the prosthesis was seen in all these X-ray films. Conclusion The short-term follow-up indicates that the patients implanted with the TC-Dynamic prosthesis have an excellent result. The TC-Dynamic prosthesis with a scientific and proper design is more suitable for the Chinese. However, the long-term outcome of the patients implanted with the TC-Dynamic prosthesis should be observed in a larger number of TKA operations. The basic surgical principles, including excision of both the cruciate ligaments and correction of thebone deformity with the proper balancing of the soft tissues in flexion and extension, are still crucial to successful TKA and to the longterm high survivalrate of the knee prosthesis.
OBJECTIVE To investigate the clinical result and influence factors of prognosis after repair of ruptured Achilles tendon with operative treatment. METHODS From 1961 to 1994, 62 cases with ruptured Achilles tendon were treated operatively. Among them, "8"-shaped suture was used in 8 cases, aponeurosis flap repair in 30 cases, transfer repair of tendon of peroneus longus muscle in 2 cases, reverse "V-Y" shaped tendon plastic operation in 10 cases, and mattress suture of opposite ends in 12 cases. RESULTS Followed up 3 to 33 years, there was excellent in 40 cases, better in 13 cases, moderate in 6 cases, poor in 3 cases, 85.5% in excellent rate. Postoperative infection and re-rupture were occurred in 6 cases respectively. CONCLUSION Different operative procedures are adopted to achieve better long-term clinical result according to the injury types.
ObjectiveTo explore the practice of the evidence-based treatment strategy for cervical spinal cord injury. MethodsOne patient with cervical spinal cord injury was admitted to our hospital on January 3, 2013. We obtained medical evidences by searching databases and regulated the best treatment after evaluating the patient's comprehensive conditions. And then, the whole treatment strategy was fully implemented. Finally, the consequent results were evaluated. ResultsThe evidence-based medicine showed that the therapeutic targets were to save the residual function, prevent complications, and promote the recovery of neural function. Based on the real-time conditions of patient, we developed and practiced the evidence-based comprehensive rehabilitation programs, including absolute rest in bed, high-dose steroids, neurotrophic drugs, Chinese medicine rehabilitation and prevention of complications. After a follow-up of half a year, the patient obtained a good curative effect. The patient was saved from paralyzing. Moreover, the patient restored the capacity of standing, walking and a certain level of self-care ability. ConclusionFor the cervical spinal cord injury, treatment decision based on evidence-based medicine is more scientific, and it can ensure maximum benefit for the patients. Therefore, it is worthy of popularizing.
