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.
OBJECTIVE To review the history and current status of total wrist arthroplasty. METHODS The original articles about wrist arthroplasty in recent years were reviewed. RESULTS The properties of wrist prosthesis of different generations were reviewed, with the emphasis on the prosthesis design and biomechanical behaviours. The surgical techniques, complications and salvage procedures were also discussed. CONCLUSION Although wrist arthrodesis is highly successful in treating the end-stage wrist arthritis, total wrist arthroplasty using well-designed prosthesis remains an alternative for the patients with special demands of hand functions.
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.
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.
Objective?To evaluate differences of clinical effects between cervical total disc replacement (TDR) and anterior cervical discectomy and fusion (ACDF) for single symptomatic single-level cervical degenerative disc disease. Methods?Randomized controlled trials (RCTs) from the Cochrane Library Central Register of Controlled Trials (Issue 1, 2009), MEDLINE (2000 to May 2009), EMbase (2000 to May 2009), Ovid (2000 to May 2009), CBM (2000 to May 2009) and CNKI (2000 to May 2009) were electronically searched. Additionally, six relevant journals were handsearched to identify RCTs about comparison of TDR and ACDF in the treatment of single-level cervical degenerative disc disease. All RCTs demonstrating these issues were included. RevMan 5.0 software was used for meta-analyses. Results?Six RCTs involving 1 340 patients were included. The results of meta-analyses indicated that there were significant differences between the two groups in neurological success (RR=1.06, 95%CI 1.02 to 1.11, P=0.003), secondary surgical procedures (RR=0.30, 95%CI 0.17 to 0.53, Plt;0.0001) and overall success (RR=1.13, 95%CI 1.06 to 1.22, P=0.0006). However, there were no significant differences in Neck Disability Index (NDI) scores (WMD=1.53, 95%CI –0.55 to 3.61, P=0.15), neck pain scores (WMD= –2.87, 95%CI 7.75 to 1.81, P=0.23), arm pain scores (WMD= –0.7, 95%CI –0.86 to –0.54, P=0.48), radiography success (RR=0.96, 95%CI 0.92 to 1.01, P=0.11), and postoperative complications (RR=0.79, 95%CI 0.49 to 1.28, P=0.34) between the two groups. Conclusion?The evidence indicates that compared with ACDF, TDR could improve neurological status, reduce secondary surgical procedures and promote overall success for single-level cervical degenerative disc disease, but there are no significant differences in postoperative NDI, neck and arm pain scores, radiography success, and complications.
Objective To evaluate the clinical effectiveness of the first metatarsophalangeal (MTP) joint arthroplasty versus arthrodesis for rheumatoid forefoot deformity. Methods The randomized controlled trials (RCTs) about the first MTP joint arthroplasty vs. arthrodesis for rheumatoid forefoot deformity published by February 2012 were searched in the databases such as CNKI, Ovid, MEDLINE, CBM, EMbase, WanFang Data, The Cochrane Library (Issue 1, 2012), and KJEBM. Two reviewers independently screened studies, extracted data, and evaluated the methodological quality according to the inclusion and exclusion criteria. Then meta-analysis was conducted using RevMan 5.1 software. Results A total of 4 RCTs were included. Among total 206 (269 feet) patients involved in, 98 (130 feet) were in the arthroplasty group, while the other 108 (139 feet) were in the arthrodesis group. The results of meta-analysis showed that the arthrodesis group was superior to the arthroplasty group in the footwear (MD=?0.88, 95%CI ?1.55 to ?0.22, P=0.01), and the alignment (MD=?5.04, 95%CI ?8.94 to ?1.14, Plt;0.000 01) with significant differences. But there were no significant differences between the two groups in patient satisfaction, metastatic lesions, pain, activity and weight-bearing of Hallux. Conclusion Based on the current studies, arthrodesis is superior to arthroplasty in treating rheumatoid forefoot deformity. For the quality restrictions and possible publication bias of the included studies, more double blind, high quality RCTs are required to further evaluate the effects.
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.
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 analyze the influence of the body mass index (BMI) and age on deep vein thrombosis (DVT) after the total hip arthroplasty(THA) or total knee arthroplasty(TKA) in Chinese patients who received prophylactic treatment for DVT. Methods We used a randomized clinical case-control study. From April 2004 to August 2004, weperformed THA and TKA for 95 patients (128 hips and knees). There were 27 men and 68 women with an average age of 60 years (range, 23-78) at surgery, and withan average BMI of 25.88 kg/m2 (range, 14.34-40.39) before surgery. All the patients were given low-molecular-weight heparin for 7-10 days pre-and postoperatively to prevent DVT. Color Doppler ultrasonography was used to detect DVT of bilateral lower extremities in all the patients before operation and 7-10 days after operation.The patients were divided into 4 groups according to their BMI:the non-obese group (BMI≤25.00 kg/m2), the overweight group (BMI, 25.01-27.00 kg/m2), the obese group (BMI, 27.01-30.00 kg/m2), and the morbidly obese group (BMIgt;30.00 kg/m2); and they were also divided into 4 groups according to their ages (≤40, 4160, 61.70, gt;70 yr) so as to analyze the influence of the BMI and age on DVT. Results The total incidence ofDVT in all the patients was 47.4% (45/95) and the incidence of proximal DVT was 3.2%. Forty-five patients had DVT and 50 patients had no DVT. The average BMI of the patients with DVT was significantly higher than that of the patients with no DVT (Plt;005). The overweight, obese, and morbidly obese patients had an odds ratio of 7.04, 4.8,and 9.6 for DVT compared with the nonobese patients (P＜0.05); but the obese group had a less risk than the other 2 groups.The 41-60, 61-70, and gt;70-year-old patients had an odds ratio of 24.0, 38.2, and 24.4 for DVT compared with the ≤40year-old patients (P＜0.05). Conclusion Obesity (BMIgt;25 kg/m2) and an increasing age (gt;40 yr) are identified as statistically significant risk factors for DVT after THA or TKA, and patients aged 61-70 years are more likely tohave DVT than the other patients. We should pay more attention to those obesity and aged patients when they are undergoing the total joint replacement, and we should give them enough prophylaxis and closely observe the symptoms in their bilateral lower extremities after operation, taking ultrasonography or venography to check DVT if necessary, so that we can give them prompt treatment and prevent fatal pulmonary thromboembolism.
