Objective To summarize the clinical outcome of the Ribbed anatomic cementless total hip arthroplasty (THA) in the treatment of hip-joint disease. Methods From January 2001 to June 2005, 34 patients(38 hips) with hip-joint disease were treated with Ribbed anatomic cementless THA. Their ages ranged from 29 to 55 years with an average age of 42.7 years.The disease course was from 3 to 18 years. Among these cases, there were 7 cases (7 hips) of femoral neck fracture, 5 cases(5 hips) of traumatic arthritis after fracture of acetabulum, 15 cases(16 hips) of necrosis of the femoral head and 7 cases(10 hips) of ankylosing spondylitis. Four patients were operated on both hip joints. The average Harris hip score was 38.6(25-57) before operation. Results Twenty-one patients(23 hips) were followed up 861 months with an average of 35 months. The Harris hip score was 76-98 after operation with an average of 92.3, showing significant difference when compared with that before operation(Plt;0.05). The excellent and good result was achieved in 93.5 % of patients. Radiographs showed no prosthetic osteolysis and no evidence of loosening. Pain in the thigh occurred in 4 patients,and it can be relieved by using nonsteroid antiinflammatory drug. Conclusion Ribbed anatomic cementless THA has good clinical and radiographic results in treating patients with hip-joint disease.
Objective To retrieve and summarize the best evidence for fall prevention after total hip arthroplasty in elderly patients. Methods BMJ Best Practice, UpToDate, JBI evidence-based healthcare center database, National Institute for Health and Clinical Excellence, Scottish Intercollegiate Guidelines Network, Cochrane Library, PubMed, Web of Science, EBSCO, International Collaboration of Orthopaedic Nurisng website, American Academy of Orthopaedic Surgeons website, European Society for Trauma and Emergency Surgery website, Medlive, China National Knowledge Infrastructure, Wanfang, Chongqing VIP, and SinoMed were systematically searched. The retrieval time was from the establishment of the databases to June 30, 2024. The quality of literature was evaluated, and evidence was extracted, evaluated, and summarized. Results A total of 12 articles were included, including 4 guidelines, 2 randomized controlled trials, 2 cohort studies, and 4 expert consensus studies. A total of 18 pieces of evidence were extracted, including 13 A-level recommendations and 5 B-level recommendations. The evidence covers six major themes of risk factors, assessment, multidisciplinary team support, health education, medication management, safety environment, and assistive devices. Conclusions The fall prevention after total hip arthroplasty in elderly patients involves multiple factors, and the fall prevention should be based on multidisciplinary team cooperation, achieving linkage between the hospital and the family to jointly ensure patient safety. In the future, it is recommended to combine individual patient differences with actual clinical scenarios when applying evidence.
Objective To systematically evaluate the difference in leg length discrepancy (LLD) between robot-assisted total hip arthroplasty (THA) and traditional THA. Methods The Cochrane Library, PubMed, Web of Science, EMbase, CNKI, Wanfang, VIP, and CBM databases were searched by computer to collect cohort studies of robot-assisted and traditional THAs from inception to August 11th, 2021. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias of the included studies. Meta-analysis was performed using RevMan 5.3 software. ResultsA total of 10 high-quality cohort studies were included. The results of Meta-analysis showed that compared with traditional THA, LLD after robot-assisted THA was smaller [MD=?1.64, 95%CI (?2.25, ?1.04), P<0.001], Harris scores at 3 and 12 months after operation were higher [MD=1.50, 95%CI (0.44, 2.57), P=0.006; MD=7.60, 95%CI (2.51, 12.68), P=0.003]. However, the operative time was longer [MD=8.36, 95%CI (4.56, 12.17), P<0.000 1], and the postoperative acetabular anteversion angle was larger [MD=1.91, 95%CI (1.43, 2.40), P<0.001]. There was no significant difference in Harris score at 6 months, amnesia index (Forgotten joint score, FJS), postoperative acetabular abduction angle, and incidence of complication between the two groups (P>0.05). Conclusion Robot-assisted THA is superior to traditional THA in postoperative LLD.
Objective To evaluate the early effectiveness of navigation-free robot-assisted total knee arthroplasty (TKA) compared to traditional TKA in the treatment of knee osteoarthritis combined with extra-articular deformities. Methods The clinical data of 30 patients with knee osteoarthritis combined with extra-articular deformities who met the selection criteria between June 2019 and January 2024 were retrospectively analyzed. Fifteen patients underwent CORI navigation-free robot-assisted TKA and intra-articular osteotomy (robot group) and 15 patients underwent traditional TKA and intra-articular osteotomy (traditional group). There was no significant difference in age, gender, body mass index, affected knee side, extra-articular deformity angle, deformity position, deformity type, and preoperative knee range of motion, American Knee Society (KSS) knee score and KSS function score, and lower limb alignment deviation between the two groups (P>0.05). The operation time, intraoperative blood loss, and complications of the two groups were recorded and compared. The knee range of motion and lower limb alignment deviation were recorded before operation and at 6 months after operation, and the knee joint function was evaluated by KSS knee score and function score. Results There was no significant difference in operation time between the two groups (P>0.05); the intraoperative blood loss in the robot group was significantly less than that in the traditional group (P<0.05). Patients in both groups were followed up 6-12 months, with an average of 8.7 months. The incisions of all patients healed well, and there was no postoperative complication such as thrombosis or infection. At 6 months after operation, X-ray examination showed that the position of the prosthesis was good in both groups, and there was no loosening or dislocation of the prosthesis. The knee joint range of motion, the lower limb alignment deviation, and the KSS knee score and KSS function score significantly improved in both groups (P<0.05) compared to preoperative ones. The changes of lower limb alignment deviation and KSS function score between pre- and post-operation in the robot group were significantly better than those in the traditional group (P<0.05), while the changes of other indicators between pre- and post-operation in the two groups were not significant (P>0.05). Conclusion Compared to traditional TKA, navigation-free robot-assisted TKA for knee osteoarthritis with extra-articular deformities results in less intraoperative blood loss, more precise reconstruction of lower limb alignment, and better early effectiveness. However, long-term effectiveness require further investigation.
Objective To investigate the development trajectories of kinesiophobia and their influencing factors in patients after total hip arthroplasty (THA). Methods Patients after THA from three tertiary hospitals in Wuhan from February to June 2023 were selected by convenience sampling method. The general situation questionnaire, Tampa Scale for Kinesiophobia, Self-Efficacy for Exercise Scale (SEE), Groningen Orthopaedic Social Support Scale, Generalized Anxiety Disorder, Patient Health Questionnaire, and Visual Analogue Scale (VAS) were distributed 1-2 d after surgery (T1), which were used again 1 week (T2), 1 month (T3), and 3 months (T4) after surgery, to evaluate the level of kinesiophobia and the physical and psychological conditions of the patients. The latent category growth model was used to classify the kinesiophobia trajectories of patients after THA, and the influencing factors of different categories of kinesiophobia trajectories were analyzed. Results A total of 263 patients after THA were included. The kinesiophobia trajectories of patients after THA were divided into four potential categories, including 29 cases in the C1 high kinesiophobia persistent group, 41 cases in the C2 medium kinesiophobia improvement group, 131 cases in the C3 low kinesiophobia improvement group, and 62 cases in the C4 no kinesiophobia group. Multicategorical logistic regression analysis showed that compared to the C4 no kinesiophobia group, the influencing factors for the kinesiophobia trajectory in THA patients to develop into the C1 high kinesiophobia persistent group were age [odds ratio (OR)=1.081, 95% confidence interval (CI) (1.025, 1.140)], chronic comorbidities [OR=6.471, 95%CI (1.831, 22.872)], the average SEE score at T1-T4 time points [OR=0.867, 95%CI (0.808, 0.931)], and the average VAS score at T1-T4 time points [OR=7.981, 95%CI (1.718, 37.074)], the influencing factors for the kinesiophobia trajectory to develop into the C2 medium kinesiophobia improvement group were age [OR=1.049, 95%CI (1.010, 1.089)], education level [OR=0.244, 95%CI (0.085, 0.703)], and the average VAS score at T1-T4 time points [OR=8.357, 95%CI (2.300, 30.368)], and the influencing factors for the kinesiophobia trajectory to develop into the C3 low kinesiophobia improvement group were the average SEE score [OR=0.871, 95%CI (0.825, 0.920)] and the average VAS score at T1-T4 time points [OR=4.167, 95%CI (1.544, 11.245)] . Conclusion Kinesiophobia in patients after THA presents different trajectories, and nurses should pay attention to the assessment and intervention of kinesiophobia in patients with advanced age, low education level, chronic diseases, low exercise self-efficacy, and high pain level.
ObjectiveTo investigate the effectiveness of total elbow arthroplasty (TEA) with preservation of triceps brachii insertion approach.MethodsBetween January 2012 and September 2017, 17 patients with elbow disease were treated with TEA with preservation of triceps brachii insertion approach. There were 3 males and 14 females, with an average age of 65.2 years (range, 48-85 years). The injuries located on left elbow in 5 cases and on right elbow in 12 cases. There were 11 cases of distal humerus fracture (AO type C1 in 2 cases and type C3 in 9 cases); the interval between fracture and operation was 3-10 days (mean, 4.1 days). There were 3 cases of osteoarthritis and 3 cases of rheumatoid arthritis, with the disease duration of 2-26 years (mean, 8.7 years). The postoperative elbow function and pain was assessed by Mayo elbow performance score (MEPS) and visual analogue scale (VAS) score, respectively. The prosthesis position, heterotopic ossification, and periprosthetic fracture were observed by X-ray films.ResultsAll incisions healed by first intention. Sixteen patients were followed up 18-69 months (mean, 40.6 months). Intraoperative ulnar nerve injury occurred in 2 cases, and healed after symptomatic treatment. At last follow-up, the MEPS score was 55-100 (mean, 90.3). The results were excellent in 11 cases, good in 2 cases, fair in 2 cases, and poor in 1 case, with an excellent and good rate of 81.3%. The VAS score was 0-2 (mean, 0.4). X-ray reexamination showed that no polyethylene wear, prosthesis loosening and fracture, abnormal prosthesis position, periprosthetic fracture occurred during the follow-up period, and the prosthesis survival rate was 100%. Heterotopic ossification occurred in 2 and 3 months after operation in 2 cases, respectively.ConclusionThe triceps on approach for TEA are satisfactory for distal humerus fracture, osteoarthritis, and rheumatoid arthritis.
【Abstract】 Objective To explore the flexibil ity and rel iabil ity of cementless total knee arthroplasty (TKA) without patellareplacement through a retrospective study of the mid-term therapeutic effect of the treatment of the patients. Methods FromJune 1997 to March 2000, a consecutive series of 152 (152 knees) cementless TKA performed in Hessing-Stiftung was studied. Among them, there were 63 males and 89 females, with 70 left knees and 82 right knees. Their ages ranged from 51 years to 72 years, with an average of 59 years. There were 146 cases of osteoarthritis and 6 cases of traumatic arthritis. The course of the disease lasted for 1.0 years to 3.5 years. The EFK prostheses of German Plus company were used in all the cases. The HSS score before the operation was 41.5 ± 12.3, and the average range of motion was 55o (ranging from 30o to 90o). Results Five patients underwent anterior knee pain, and the pain was released after the appropriate treatment. No deep infection happened in all cases. A total of 145 patients (145 knees) were followed up for 5 years to 8 years. The HSS score was 87.5 ± 8.2 at the end of the follow-up, showing significant difference (P lt; 0.05). The average range of motion was 95o (ranging from 90o to 110o). Partial radiolucencies occurred at the tibia side in 18knees 3 to 6 months after the operation. Among them, the width was less than 2 mm in 15 knees without symptom, and more than 2 mm in 3 knees. There were 2 of the 3 knees which were revised at the tibia side because of the aseptic loosing, while 1 patient had only mild pain in the knee during the follow-up, with no sign of loosing. Conclusion The mid-term effect of cementless TKA is satisfactory. The ingrowth of femur and tibial bones is rel iable. The early stage migration of the component is the main reason of loosing. Satisfying outcomes can also be achieved without patella replacement during TKA.
ObjectiveTo evaluate the accuracy of using smartphone to measure the angle of acetabular component in total hip arthroplasty (THA). MethodsBetween June 2012 and September 2015, the acetabular abduction and anteversion angles were measured in 50 patients undergoing THA. There were 24 males and 26 females, aged 37 to 83 years (mean, 71 years). The left hip was involved in 22 cases and the right hip in 28 cases. Of 50 patients, 34 suffered from fracture of the femoral neck, and 16 suffered from avascular necrosis of the femoral head. Acetabular dysplasia was excluded in all cases. A smartphone was used to measure the acetabular abduction and anteversion angles during operation; standard Picture Archiving and Communication Systems (PACS) was used to measured the acetabular abduction and anteversion angles on the X-ray film at 1 week after operation. It was defined as positive that the component angle values by PACS measurement were greater than those by the smartphone measurement, whereas as negative. The two measurement methods were compared, and intra-observer variability was assessed by analyzing the intraclass correlation coefficient (ICC), the Mann-Whitney U-test was used to analyze difference. ResultsThe ICC was 0.84 in the acetabular component angles by smartphone and PACS measurement methods. The acetabular component abduction angle was (44.02±1.33)° and the anteversion angle was (17.62±2.20)° by smartphone measurement. The acetabular component abduction angle was (44.74±4.05)° and the anteversion angle was (17.22±5.57)° by PACS measurement. There was no significant difference between two measurement methods (Z=-1.977, P=0.482; Z=-0.368, P=0.713). The acetabular component angle was in the safe zone in 44 cases; and the acetabular component anteversion angle was beyond safe range of 1 to 5°, and the abduction angle was beyond safe range of 1 to 3° in 6 cases. Intra-measurement variability was -21 to +10° for the anteversion angle and -10 to + 9° for the abduction angle, indicating that the acetabular component anteversion angle by smartphone measurement was greater than that by the PACS measurement, and the abduction angle was less than that by PACS measurement. ConclusionSmartphone is a convenient tool to measure the acetabular component angle in THA.
ObjectiveTo investigate the effect of platelet rich plasma (PRP) in promoting wound healing of total hip arthroplasty (THA). MethodsBetween January 2011 and January 2012, 80 patients scheduled for THA and accorded with the inclusion criteria were divided into 2 groups:wounds were treated with PRP in 40 patients (PRP group) and with normal saline in 40 patients (control group). There was no significant difference in gender, age, disease duration, injury causes, sides, fracture type, and preoperative Harris hip scores between 2 groups (P>0.05). Routine drainage and functional exercise were performed after operation. ResultsThe postoperative drainage volume of PRP group[(137±26) mL] was significantly lower than that of control group[(424±39) mL] (t=38.726, P=0.000). At 4 days after operation, no inflammatory reaction was observed in 34 cases of PRP group and in 30 cases of control group, mild inflammatory reaction in 5 cases of PRP group and in 6 cases of control group, moderate inflammatory reaction in 1 case of PRP group and in 4 cases of control group; there was no significant difference between 2 groups (χ2=2.141, P=0.343). Wound healed by first intention in 40 patients of PRP group and in 39 patients of control group, showing no significant difference between 2 groups (P=1.000). The average follow-up period was 9 months (range, 6-12 months). The Harris hip scores of PRP group (90.2±2.5) and control group (89.3±3.1) at last follow-up were significantly better than those before operation (39.6±8.9 and 39.2±9.2 respectively) (t=34.618, P=0.000; t=32.638, P=0.000), but no significant difference was found between 2 groups (t=1.429, P=0.153). ConclusionUsing PRP in THA wound can reduce postoperative drainage volume, improve the healing of operation incision. It is a safe, effective, and promising procedure in treatment of THA wound.
ObjectiveTo evaluate the clinical and radiographic outcomes of hip resurfacing arthroplasty (HRA) for treating osteonecrosis of the femoral head (ONFH) in young and middle-aged patients. MethodsBetween January 2008 and April 2009, 34 patients with ONFH underwent HRA. There were 19 males and 15 females with an average age of 54 years (range, 33-59 years). Of 34 cases, 16 left hips and 18 right hips were involved, including 9 cases of alcoholinduced ONFH, 8 cases of steroid-induced ONFH, 7 cases of traumatic ONFH, and 10 cases of unexplained ONFH. According to modified Ficat classification system, 26 hips were rated as stage III, and 8 hips as stage IV. The Harris hip score (HHS) and modified University of California, Los Angeles (UCLA) activity score were used to evaluate the clinical results. Migration of prosthesis was assessed on the anteroposterior radiographs. The abduction angle was measured on the acetabular side. On the femoral side, varus-valgus shift was determined by measurement of stem-shaft angle. The axial collapse of femoral component was assessed with the component-lateral cortex ratio. ResultsHealing of incision by first intention was achieved in all patients without complications of infection and thrombosis of deep vein of lower extremities. Thirty-two patients were followed up 78 months on average (range, 70-84 months). No implant loosening, infection, femoral neck fracture, dislocation, and inflammatory pseudotumor were observed. At last follow-up, the HHS score was significantly increased to 95.22±1.47 from preoperative 50.10±2.27 (t=1.510, P=0.008). Modified UCLA activity score was significantly increased to 7.70±1.13 from preoperative 3.90±0.90 (t=0.830, P=0.003). The abduction angle, stemshaft angle, and compotent-lateral cortex ratio showed no significant difference between at 3 days after operation and last follow-up (P>0.05). ConclusionIf the indication of operation is mastered strictly, HRA may be effective in treatment for ONFH at Ficat stage III or IV in young and middle-aged patients.
