Objective To discuss shortterm effect of rotating hinge knee prosthesis. Methods From July 2002 to April 2005, 17 cases of severe knee joint deformity and instability received rotating hinge knee prosthesis for total knee arthroplasty. There were 8 males and 9 females, aging from 41 to 79 years. The left joints were involved in 10 cases and right joint in 7 cases. All patients were admitted because of pain. The course of disease was from 1 to 7 years. There were 10 cases of osteoarthritis，5 cases of rheumatoid arthritis，1 case of traumatic arthritis after operation of left femur fracture，and 1 case of traumatic arthritis with injury of anterior cruciate ligament, meniscus medialis and medial collateral ligament after operation of left fracture of tibial plateau. According to HSS(hospital for special surgery) scoring system，the preoperative score was 36 to 58 with an average of 48.6. The preoperative flexed motion range of articulation was 21° to 80° with an average of 57.4°. Results All patients were followed up from 7 months to 3 years with an average of 23.6 months. There were no complications of thrombogenesis of veins of lower extremity, pulmonary embolism, palsy of peroneal nerve, fracture, and breakage of extended knee structure. Infection occurred in 1 case at 3 months postoperatively，the prosthesis was dislodged，antibiotic-impregnated cement was filed with knee joint，twostage arthroplasty was expected. At the last follow-up,the HSS score was 78 to 98 with an average of 91.1 in 16 patients. The flexed motion range of articulation was 75° to 100° with an average of 852° at 2 weeks postoperatively. The flexed motionrange of articular was 85° to 123° with an average of 1083° at the last followup. There were significant differences in HSS score and motion range of articular between preoperation and thelast follow-up (P＜0.05). Conclusion The short-term outcome of rotating hinge knee prosthesis is good and a long term followup is necessary.
ObjectiveTo investigate and analyze comorbidities of elderly patients with total hip/knee arthroplasty, so as to provide a basis for the management of comorbidities.MethodsConvenience sampling was used to select elderly patients who underwent total hip/knee arthroplasty in the Department of Orthopedics in West China Hospital of Sichuan University from June to December 2019 as the research objects. We collected general data and comorbidity data of patients, and statistically analyzed the comorbidities of elderly patients undergoing total hip/knee arthroplasty, and the characteristics of perioperative psychology, sleep, postoperative complications, and length of hospital stay in elderly patients undergoing total hip/knee arthroplasty with comorbidities.ResultsA total of 263 patients were included, of whom 64.6% had comorbidities. The number of comorbidities in elderly patients undergoing total hip/knee arthroplasty ranged from 2 to 12. The most common comorbidity was hypertension. Between patients with comorbidities and non-comorbidities, there were statistically significant differences in age (Z=−2.225, P=0.026), preoperative Huaxi Emotion Index scores (9.6±4.6 vs. 6.4±5.0; t=5.126, P<0.001), preoperative Pittsburgh Sleep Quality Index scores (13.3±3.1 vs. 12.3±2.5; t=−2.972, P=0.003), hospital stay [(5.2±0.8) vs. (4.8±0.4) d; t=4.243, P<0.001], and incidence of postoperative complications (13.5% vs. 5.4%; χ2=4.201, P=0.040).ConclusionsComorbidities are common in elderly patients with total hip/knee arthroplasty, which may aggravate negative emotions, reduce sleep quality, increase postoperative complications and prolong length of stay. Medical staff should strengthen the management of comorbidity in elderly patients with total hip/knee arthroplasty, so as to reduce its influence on perioperative period and promote the rehabilitation of patients.
Objective To explore the intraoperative imaging to monitor the prosthetic fixation for the total hip arthroplasty (THA) and to increasethe accuracy of the primary THA prosthetic fixation. Methods From April 2000 to August 2005, 69 patients (75 hips) underwent THA monitored by the imaging (the imaged THA group, Group I), and 72 patients (78 hips) underwent THA with the standard method (the standard THA group, Group S). There were 32 males and 37 females in Group S. The mean ages of the patients in Group I and Group S were 62.3 years and 60.5 years respectively, ranging 46-75 years in Group I and 43-75 years in Group S. Preoperative diagnoses were femoral neck fracture (Garden Ⅲ,Ⅳ) in 23 patients (23 hips) in Group I and 25 patients (25 hips) in Group S, acetabular dysplasia (Campbell Ⅰ, Ⅱ) in 9 patients (10 hips) in Group I and 11 patients (13 hips) in Grouop S, osteoarthritis in 16 patients (17 hips)in Group I and 15 patients (15 hips) in Group S, femoral head osteonecrosis (Ficat Ⅲ,Ⅳ) 15 patients (16 hips) in Group I and 17 patients (17 hips) in Group S, and rheumatoid arthritis in 6 patients (9 hips) in Group I and 4 patients (8 hips) in Group S. There were 21 hips of cement prostheses in Group I and 22 hips in Group S, 12 hips of cementless prostheses in Group I and 11 hips in Group S, 42 hips of cement and cementless prostheses in Group I and 45 hips in Group S. Group I used the standard THA and the intraoperative X-ray monitoring the prosthetic fixation in the numerical measure of abduction angle, anteversion angle, femoralneck length, and femoral offset distance. The items compared betweem Group I and Group S included incisional length, intraoperative bleeding, transfusion, operative time, frequency of X-ray imaging, infection, postoperative functional recovery, and prostheric position of postoperative X-ray imaging. Results The follow-up on 62 patients in Group I and 64 patients in Group S for 6-64 months averaged 42 months revealed that there were statistically significant differences in incisional length, intraoperative bleeding, transfusion, operative time, frequency of X-ray imaging, postoperative functional recovery, prosthetic position of postoperative X-ray imaging, and the Harris score between Group I and Group S one year after operation. The results of Group I were significatly better than those of Group S. Conclusion The intraoperative X-ray imaging can increase the accuracy of the THA prosthetic fixation and reduce the incidence of THA maloperation by The X-ray imaging can also be used in county hospitals if Carm fluoroscopy can be provided.
Objective To estimate the clinical curative effect of replacement of inverttype artificial total scapula and shoulder joint prosthesis and reserving arm with rehabilitation of function in the treatment of malignant tumor in shoulder. Methods From February 2001 and November 2004, five youth patients with primary malignant shoulder tumors were treated operatively by resection of neoplasmsthoroughly, replacement of inverttype artificial total shoulder blade and joint prosthesis, the functional reconstruction. Of them, there were 4 males and 1 female, aging from 19 to 26 years with an average of 23.6 years. Two cases were diagnosed as having osteosarcoma, one as having chondrosarcoma, and 2 as having Ewing sarcoma. After operation, the upper limbs was immobilized for 3 weeks. The rehabilitation training including passive exercise and initiative exercise. Results The average operative time was 425 min (380 to 530 min), and the blood loss ranged from 1 250 ml to1 900 ml(1 540 ml on average). The follow-up ranged from 7 to52 onths,with an average of 24.6 months. Postoperative complication included 1 case of pneumothorax, one case of shoulder incision skin part necrosis and 1 case of clavicle stump raising and pierce skin with shallow infection. No complication of postoperative incision deeply infection, nerve damage and prosthesis exposure or dislocation occurred. According to the scoring system of JOA(Japan orthopaedics association), the average score was 65 (60 to 72). The flexion and extension function of elbow joint recovered to normal. Conclusion The replacement of inverttype artificial total scapula and shoulder joint prosthesis is an efficacious method for the treatment of malignant tumor in shoulder. There are advantages of numerous adaption, wide range of motion and goodstability. It can not only reserve arm but also rehabilitate function.
ObjectivesTo systematically review the efficacy and safety of controlled hypotension for total hip or knee replacement.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect randomized controlled trials (RCTs) on controlled hypotension for total hip or knee replacement from inception to September 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by RevMan 5.3 software.ResultsA total of 15 RCTs involving 854 patients were included. The results of meta-analysis showed that compared with no controlled hypotension during surgery, controlled hypotension could reduce intraoperative blood loss (MD=−267.35, 95%CI −314.54 to −220.16, P<0.000 01), allogeneic blood transfusion (MD=−292.84, 95%CI −384.95 to −200.73, P<0.000 01), and 24 h postoperative mini-mental state examination (MMSE) score (MD=−1.08, 95%CI −1.82 to −0.34, P=0.004). However, there were no significant differences in 96 h postoperative MMSE score (MD=−0.11, 95%CI −0.50 to 0.28, P= 0.57) and intraoperative urine volume (MD=57.93, 95%CI −152.57 to 268.44, P=0.59).ConclusionsThe current evidence shows that controlled hypotension during total hip or knee replacement can reduce intraoperative blood loss and allogeneic blood transfusion. Furthermore, there is no obvious effect on the maintenance of blood perfusion in important organs, despite certain effects on the postoperative cognitive function, which can be recovered in short term. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
ObjectivesTo explore the status quo of the readiness for hospital discharge and the quality of discharge guidance in patients after total hip/knee arthroplasty, and analyze their correlations.MethodsA cross-sectional survey was conducted to investigate patients who underwent total hip/knee arthroplasty in a tertiary hospital in Chengdu between January and November 2017. The survey included basic patient information questionnaire, Readiness for Hospital Discharge Scale, and the Quality of Discharge Teaching Scale.ResultsThe average age of 352 patients undergoing total hip/knee arthroplasty was (59.56±12.69) years. The total score of readiness for hospital discharge was 177.08±19.41, the average score was 7.82±0.88, and the average quality of discharge teaching was 145.87±14.87. There was a statistically significant difference between the patients’ access and the required discharge teaching (t=28.742, P<0.001). The score of readiness for hospital discharge was positively correlated with the score of the quality of discharge guidance (r=0.645, P<0.001), the obtained content dimension (r=0.542, P<0.001), and the teaching skill dimension (r=0.522, P<0.001).ConclusionsThe readiness for hospital discharge in patients after total hip/knee arthroplasty is in a medium level, and the quality of discharge teaching is higher overall and it is positively correlated with the readiness for hospital discharge. Medical staff should pay attention to the discharge guidance for patients. In the course of health education, not only the content and quantity of guidance should be emphasized, but also the guiding skills should be paid attention to, so as to improve the quality of discharge teaching, thereby improving the patient’s discharge readiness and promoting the patient’s later rehabilitation.
Objective To study the effect of all-coated long stem prosthesis associated with allograft in revision total hip replacement (THR). Methods From January 1997 to January 2004, 20 patients with non-infectious loosened implant after primary THR were treated. There were 12 males and 8 females with a mean age of 65 years (58-77 years). The average period between primary THR and revision THR was 12 years (3-18 years). According to classification of Paprosky, there were10 cases of type II, 6 cases of type IIIA, 3 cases of type IIIB and 1 case of type IV. All-coated long stem prosthesis was used in all cases. Impacting bone grafting was done in 12 cases and impacting bone grafting associated with cortical strut grafting in 8 cases. The mean amount of morsel ized bone was 20 g (5-35 g), the length of cortical bone was 10-22 cm. Results All the incisions got heal ing by first intension. All patients were followed up for an average period of 36 months (16-48 months). Dislocation occurred at 5 days after operation and was cured with closed reduction and traction in 1 case. There was significant difference (P lt; 0.05) in the mean Harris score between preoperation (50.0 ± 2.3) and postoperation (90.0 ± 2.5). The X-ray checking showed that continuous radiolucent l ine of 3 mm occurred in 1 case, prosthesis subsidence of 5 mm and 7 mm in 2 cases and that no bone absorption was observed. Seven cases of cortical bone grafting union was achieved within 3 years except 1 case of cortical bone un-union. Conclusion It can obtained the initial stabil ization of prosthesis to use all-coated long stem prosthesis associated with allograft in revision THR to treat femur bone defect after THR. The short-term effects of the cl inical and X-ray checking are satisfactory, but future effect is to be observed.
Objective To review the research progress of intelligent remote follow-up modes in the application after hip and knee arthroplasty. Methods Extensive literature on this topic published in recent years both domestically and internationally was reviewed, and the application of intelligent remote follow-up modes after hip and knee arthroplasty was summarized and analyzed. Results The intelligent remote follow-up mode is a novel follow-up method based on network information technology. Patients who undergo hip and knee arthroplasty require long-term follow-up and rehabilitation guidance after operation. Traditional outpatient follow-up is relatively time-consuming and inconvenient for some patients in terms of travel and transportation, which makes the application of intelligent remote follow-up modes increasingly widespread worldwide. The inherent attributes of remote interaction and instant feedback of this mode make it particularly valued in the field of hip and knee arthroplasty. Artificial intelligence (AI)-based voice follow-up systems and virtual clinics have significant advantages in improving follow-up efficiency, reducing human resource costs, and enhancing patient satisfaction. Conclusion The existing intelligent follow-up system has formed a standardized protocol in remote follow-up and rehabilitation guidance. However, there are still shortcomings in the formulation of personalized rehabilitation plans and the gerontechnological adaptation of human-computer interaction. In the future, it is necessary to construct a multimodal data fusion platform and establish technical application guidelines for different rehabilitation stages.
Since 1985, on the basis of anatomical observation of 50 fresh adult specimens, we designed the transposition oF vascularized capitate bone carrying the dorsal branche of the anteriot interosses artery to replace the damaged lunate bone from avascular necrosis. The operation had been done in 6 patients and the follow-up observation (from 6 months to 4 years) showed that the operation was satisfactory. The anatomic basis, the advantages and disadvantages, and the surgical indications were discussed.
ObjectiveTo summarize the perioperative blood management strategies for joint arthroplasty. MethodsThe literature concerning preoperative, intraoperative, and postoperative blood management was reviewed and summarized. ResultsAt present, a variety of blood management and conservation strategies are available. Preoperative strategies include iron supplementation, erythropoietin (EPO), and preoperative autologous donation (PAD). Intraoperative options include acute normovolemic hemodilution (ANH), antifibrinolytics, and the use of a tourniquet. Postoperative strategies include the use of reinfusion systems and guided transfusion protocols. Preoperatively, administration of either simple EPO or a combination of EPO and PAD can be efficacious in anemic patients. Intraoperatively, tourniquet use and tranexamic acid can effectively control bleeding. Postoperatively, appropriate transfusion indications can avoid unnecessary blood transfusions. ConclusionPerioperative blood management strategies for joint arthroplasty should be integrated for the individual patient using a variety of ways to reduce perioperative blood loss and blood transfusion, and promote the rehabilitation of patients.
