ABSTRACT

OBJECTIVE@#To compare the long-term follow-up effect and complications of ceramic on ceramic (CoC) interface and ceramic on polyethyleneon ceramic (CoP) interface in primary total hip arthroplasty, and provide clinical evidence.@*METHODS@#Search PubMed, EMBase, the CoChrane Library databases, Web of science, Wanfang database, and CNKI from January 2000 to September 2021, screening and inclusion of randomized controlled trials (RCTs) comparing the long-term efficacy and complications of CoC interface and CoP interface in total hip arthroplasty. Literature screening, quality evaluation and data extraction were carried out according to the inclusion and exclusion criteria, using Review Manager 5.3 statistical software. The software was used to perform statistical analysis on joint function, revision, prosthesis fracture, abnormal joint noise, and prosthesis wear rate after CoC or CoP.@*RESULTS@#Seven RCTs studies were included, including 390 cases of hips with CoC artificial joints and 384 cases of hips with CoP artificial joints. The long-term joint function improvement of CoC and CoP artificial joints was similar and there was no significant differences, with an average difference was MD=0.63, 95%CI=(-1.81, 3.07), P=0.61. About the postoperative complications, CoC artificial joints have higher incidence rate of abnormal joint noise, with odds ratio (OR)=11.05, 95%CI=(2.04, 59.84), P=0.005. CoP artificial joints wear faster, with an average MD=-87.11, 95%CI=(-114.40, -59.82), P<0.000 1. There was no significant difference between the two groups in the replacement-related complications such as joint dislocation, prosthesis loosening, osteolysis, and the rate of prosthesis revision caused by various reasons.@*CONCLUSION@#The clinical function results and complications of CoC artificial joints are comparable to those of CoP artificial joints. Although CoP artificial joint prosthesis has a faster wear rate, it does not affect joint function and increase complications, and there is no abnormal joint noise. CoC is expensive and the long-term efficacy is equivalent to CoP. Clinicians should consider cost performance when choosing CoC.

ABSTRACT

Up to now, surgical treatment of recurrent lateral patellar dislocation mainly includes: medial patellofemoral ligament reconstruction, tibial tubercle osteotomy, trochleoplasty, lateral retinacular release, derotation osteotomy and so on . Clinical reports show that: the use of a single or combined with several methods have achieved ideal short to mid-term clinical outcomes. However, there is no consolidate criterion concerning the choices of different kinds of surgical ways for the treatment of individual recurrent lateral patellar dislocation. Meanwhile, with the wide use of MPFL reconstruction and other surgical options, there are more and more complications and failures that are worthy and necessary for us to pay attention to, even though its high success rate. The aim of this article is to make a systematic review of the application status of different surgical methods, collecting the positive results we have achieved, illuminating application keys of surgical techniques, guiding patient-specific therapy more precisely.

ABSTRACT

Pericellular matrix (PCM) is a narrow tissue region surrounding chondrocytes, which "chondron" with its enclosed cells. A number of studies suggested that PCM is rich in proteoglycans, collagen and fibronectin, and plays an important role in regulating microenvironment of chondrocytes. Direct measures of PCM properties through micropipette aspiration technique showed that PCM was different from mechanical property of chondrocytes and nature extracellular matrix. However, the function of PCM is not clear, and need further study.

ABSTRACT

Total knee arthroplasty (TKA) identified as an effective treatment for ultimate knee joint disease can effectively relieve pain, correct deformity, improve knee function and enhance the quality of life of patients. Patient satisfaction has been increasingly considered as an important factor in evaluating the success of primary TKA. Anterior knee pain that usually appears in the region of the anterior knee is a recognized complaint for primary TKA and has a strong impact on the improvement of knee function and patient satisfaction of primary TKA. Accordingly, the relief of anterior knee pain has become one of the primary goals of primary TKA. At present, soft tissue lesions around the patellar caused by patellar maltracking and the elevation of internal pressure in subchondral bone because of the high contact stress of patellofemoral joint are both considered as the mechanism of anterior knee pain. For the past few years,on increasing number of studies have focused on the prevention of anterior knee pain following primary TKA. However, none of the past treatment such as patellar resurfacing, patellar denervation without patellar resurfacing or a mobile-bearing prosthesis has a good and affirmative effect on it. The prevention and treatment of anterior knee pain following primary TKA still is a difficult solved problem. To address this problem, we need further researches about the cause of anterior knee pain, knee joint prosthesis and biomechanics of patellofemoral joint, as well as lots of randomized controlled trials.

ABSTRACT

<p><b>OBJECTIVE</b>To study effects of body mass index (BMI) on postoperative outcome in patients with osteoarthritis after total knee arthroplasty (TKA).</p><p><b>METHODS</b>The data of 148 patients with osteoarthritis who underwent TKA from June 2006 to May 2009 in our hospital and had complete follow-up data were analyzed restrospectively, including 29 males and 119 females, ranging in age from 39 to 89 years old, with an average age of 71.2 years old. According to BMI classification standard, all the patients were divided into 4 groups: non-obese group (BMI ≤ 25.0 kg/m2), had 38 patients (45 knees), including 9 males and 29 females, with a mean age of (70.0 ± 8.2) years old; overweight group (BMI 25.1 to 27.0 kg/m2), had 40 patients (48 knees), including 10 males and 30 females, with a mean age of (72.6 ± 7.4) years old; obesity group (BMI 27.1 to 30.0 kg/ m2), had 30 patients (43 knees), including 7 males and 30 females, with a mean age of (70.4 ± 6.0) years old; morbidly obesity group (BMI > 30.0 kg/m2), 33 patients (39 knees), including 3 males and 30 females, with a mean age of (71.7 ± 6.4) years old. The index such as Knee Society Score (KSS), anterior knee pain and patella cartilage damage during surgery were recorded before surgery and at the time of follow-up.</p><p><b>RESULTS</b>Postoperative KSS increased significantly compared to preoperative KSS, and the good rate reached to 97.1%. In the knee score, preoperative KSS and postoperative KSS had no significant differences among the four groups (preoperative P = -0.789; postoperative P = 0.133). However, compared with other groups, obesity group got the lowest preoperative function score (preoperative P = 0.036; postoperative P = 0.225). While the incidence of anterior knee pain was 9.7% (17/175), including 14 grade I and 3 grade II. There were no significant differences in incidence of anterior knee pain among four groups (χ2 = 0.764, P = 0.862). The average BMI of the patients with anterior knee pain was (27.4 ± 3.6) kg/m2, while the others' BMI was (27.5 ± 4.4) kg/m2. There was no statistically difference between two groups (t = -0.061, P = 0.951). There were no significant differences in patella cartilage damage among groups (χ2 = 7.070, P = 0.314).</p><p><b>CONCLUSION</b>The KSS increases in all the different groups. Those patients get the benefit from TKA, and the obese patients can receive a similar postoperative outcome as the non-obese ones.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the therapeutic effects between close reduction and plaster slab fixation combined with plaster external traction and operation for the treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications.</p><p><b>METHODS</b>From June 2009 to June 2012, 151 children with closed Gartland III supracondylar humerus fractures were retrospectively studied and divided into two groups, including 87 boys and 64 girls, ranging in age from 1 to 12 years old with an average of 5.3 years old. Among them, 76 children (conservative group) were treated with close reduction and plaster slab fixation combined with plaster external traction; 75 children (operation group) underwent surgical operation. The time of elbow joint function exercise, the healing time of fracture, the function recovery of elbow joint and carrying angle was recorded and analyzed. The therapeutic effects were evaluated by the Flynn criteria system.</p><p><b>RESULTS</b>All patients were followed up from 6 to 36 months (18.3 months on average). The average time of fracture healing and elbow joint functional exercise of the conservative group was shorter than those of operation group (P < 0.001). Motion range of the elbows and carrying angle of two groups were no statistical difference (P > 0.05). According to Flynn criteria system, in conservative group, the result was excellent in 31 cases, good in 35, fair in 7, and poor in 3; in operation group, 27 in excellent, 30 in good, 17 in fair and 1 in poor; there was no significant difference between two groups in therapeutic effects (P > 0.05).</p><p><b>CONCLUSION</b>Close reduction and plaster slab fixation combined with plaster external traction in treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications,which has similar effect to surgical treatment, and the time of fracture healing and elbow joint function exercise are significantly shorter.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore method of recombinant gene lentivirus containing LIM mineralization protein-1 (LMP-1) in transfecting bone marrow mesenchymal stem cells (BMSC), and to observe the effect of gene LMP-1 on proliferation effect and expression of BMSC.</p><p><b>METHODS</b>Six clean SD rats aged 4 weeks were selected, bone marrow mesenchymal stem cells were extracted under sterile conditions and cultured to the third generation, then divided into three groups:control group (the third generation of BMSC), lentiviral vector transfection group (PGC-FU-GFP and Polybrene were injected into the third generation of BMSC) and recombinant gene transfection group (PGC-FU-LMP-1-GFP and Polybrene transfection were injected into the third generation of BMSC). After 48 hours' transfection, fluorescent expression were detected under immuno-fluorescence microscopy; lentiviral transfection efficiency were detected by flow cytometry; effect of lentiviral transfection on BMSC were evaluated by MTT; gene expression of transfected cells were determined by Western Blot.</p><p><b>RESULTS</b>1) The third generation of BMSC was cultured successfully,and transfected with MOI:100. After 48 hours, green fluorescent expression were detected and transfection efficiency was 67% under immuno-fluorescence microscopy; 2) Compared to control group, there were no statistical differences between control group and other two groups; 3) Western blot teast showed that 72KDa specific band was observed in recombinant gene transfection group and its size was similar to LMP-1 fusion protein (50 kDa+28 kDa=78 kDa).</p><p><b>CONCLUSION</b>There is no effect of recombinant gene lentivirus containing LIM on BMSC, and can effectively influence the expression of LMP-1.</p>

ABSTRACT

Osteoporosis vertebral compression fractures seriously affect the life and health of the elderly,indicating the elderly life health begin to decline. Therefore, aggressive treatment is particularly important. Traditional surgical method,such as laminectomy and internal fixation has large trauma,more blood loss and high failure rate. However, conservative treatment cannot early reduce pain symptoms and improve functional status,it can lead delayed union and severe ossification and form chronic OVCF,make more difficult to treat. In treatment of vertebral body fracture,there was a new way with the development of minimally invasive spinal surgery technology. Percutaneous vertebroplasty and percutaneous kyphoplasty has become the commonly used method in treating OVCF. With rapid and significant analgesic effect,vertebral body height recovered ideally, the patients can early load activities and preoperative complications is rare. Effective rehabilitation exercise is also important in treating OVCF by surgery at the same time.

ABSTRACT

<p><b>OBJECTIVE</b>To discuss the clinical effects of percutaneous kyphoplasty (PKP) for acute and chronic osteoporotic vertebral compression fractures (OVCF).</p><p><b>METHODS</b>From June 2006 to October 2011,42 senior patients with OVCF were treated with PKP. There were 5 males and 37 females,ranging in age from 60 to 86 years old with an average of (73.3+/-7.5) years old. The patients were divided into two groups (acute group and chronic group) according to the course,MRI and whether or not undergoing systematically conservative. VAS and ADL scoring systems were used to evaluate the pain and daily activities. X-ray was used to evaluate the vertebral height restoration rate and the kyphosis correction rate.</p><p><b>RESULTS</b>All patients were followed up from 10 to 64 months with an average of 17 months. At 1 week and 6 months after operation in two groups, VAS and ADL scores decreased significantly (P<0.05) ;VAS and ADL scores at 6 months after operation were higher than at 1 week after operation (P>0.05). But the improvement rates of the pain and daily activities of acute group were better than that of chronic group (P<0.05). At 1 week after operation,the restoration rate of anterior and middle vertebral height,the kyphotic correction rate in acute group were better than that of chronic group (P<0.05). CONCLUCSION: Using PKP to treat both acute and chronic osteoporotic vertebral compression fractures can get good effects,but acute patients can obtain better effects than chronic patients,it has obviously advantages of relieving pain,correcting kyphotic angle,recovering vertebral height.</p>
