ObjectiveTo investigate the effectiveness of digital three-dimensional (3D) printing osteotomy guide plate assisted total knee arthroplasty (TKA) in treatment of knee osteoarthritis (KOA) patients with femoral internal implants. Methods The clinical data of 55 KOA patients who met the selection criteria between July 2021 and October 2023 were retrospectively analyzed. Among them, 26 cases combined with femoral implants were treated with digital 3D printing osteotomy guide plate assisted TKA (guide plate group), and 29 cases were treated with conventional TKA (control group). There was no significant difference in gender, age, body mass index, side, Kellgren-Lawrence classification, preoperative visual analogue scale (VAS) score, Hospital for Special Surgery (HSS) knee score, knee range of motion, and other baseline data between the two groups (P>0.05). The operation time, intraoperative blood loss, incision length, postoperative first ambulation time, surgical complications; VAS score, knee HSS score, knee range of motion before operation, at 1 week and 3 months after operation, and at last follow-up; distal femoral lateral angle, proximal tibial medial angle, hip-knee-ankle angle and other imaging indicators at last follow-up were recorded and compared between the two groups. ResultsThe operation time, incision length, intraoperative blood loss, and postoperative first ambulation time in the guide plate group were significantly lower than those in the control group (P<0.05). In the control group, there were 1 case of incision rupture and bleeding and 1 case of lower limb intermuscular venous thrombosis, which was cured after symptomatic treatment. There was no complication such as neurovascular injury, incision infection, or knee prosthesis loosening in both groups. Patients in both groups were followed up 12-26 months, with an average of 16.25 months. The VAS score, HSS score, and knee range of motion improved at each time point after operation in both groups, and further improved with time after operation, the differences were significant (P<0.05). The above indicators in the guide plate group were significantly better than those in the control group at 1 week and 3 months after operation (P<0.05), and there was no significant difference between the two groups at last follow-up (P>0.05). At last follow-up, the distal femoral lateral angle, the proximal tibial medial angle, and the hip-knee-ankle angle in the guide plate group were significantly better than those in the control group (P<0.05). Conclusion The application of digital 3D printing osteotomy guide plate assisted TKA in the treatment of KOA patients with femoral implants can simplify the surgical procedures, overcome limitations of conventional osteotomy guides, reduce surgical trauma, achieve individualized and precise osteotomy, and effectively restore lower limb alignment and knee joint function.
Objective To study the effect of multi-disciplinary treatment (MDT) on the surgical efficacy and satisfaction of patients undergoing total knee arthroplasty (TKA) for the first time. Methods The clinical data of patients who underwent unilateral TKA for single-compartment osteoarthritis of the knee in the General Hospital of Ningxia Medical University between January and September 2022 were retrospectively collected and analyzed. According to whether MDT was performed on patients during the perioperative period, they were divided into MDT group and traditional group. Perioperative nutrition-related indicators, perioperative complications, total hospitalization time, Visual Analogue Scale (VAS), and Hospital for Special Surgery Knee Score (HSS) before and after surgery were detected and recorded. Results A total of 95 patients were included. Among them, there were 42 cases in the MDT group and 53 cases in the traditional group. The postoperative complications and total hospital stay of patients in the MDT group were lower than those in the traditional group, and their satisfaction scores were higher than those in the traditional group (P<0.05). The perioperative serum total protein (TP), hemoglobin (Hb), serum albumin (ALB) levels, VAS score, and HSS score of both groups of patients changed over time. The intra group comparison results showed that compared with preoperative, the levels of TP, Hb, and ALB in both groups decreased on the 1st and 3rd postoperative days (P<0.05). On the 3rd day after surgery, the levels of TP, Hb, ALB in the MDT group and Hb, ALB in the traditional group were lower than on the 1st day after surgery (P<0.05). There was no statistically significant difference in TP levels between the traditional group on the 3rd day after surgery and the 1st day after surgery (P>0.05). The results of intra group comparison at different time points showed that there were statistically significant differences in VAS score and HSS score between the two groups (P<0.05). Conclusion The application of MDT in elderly patients undergoing unilateral TKA for the first time can shorten the total hospitalization time, reduce the incidence of perioperative complications, and improve the surgical efficacy and patient satisfaction.
Focused low-intensity pulsed ultrasound (FLIPUS), as a non-invasive physical therapy, is widely used in orthopedics, neurosurgery, urology, rehabilitation medicine and other clinical specialties. More and more studies have found that FLIPUS can treat knee osteoarthritis (KOA) by promoting tissue regeneration, relieving pain and inhibiting inflammation, improve the common clinical symptoms of KOA, such as joint pain or stiffness, limited joint activity and decreased walking function, and improve the quality of life of patients to a certain extent. This article mainly reviews the effect and biophysical mechanism of FLIPUS in the treatment of KOA, as well as related clinical research, in order to provide a reference for clinical workers who carry out research in this field.
Knee osteoarthritis (KOA) is a common chronic degenerative osteoarthritic disease with a high incidence especially among middle-aged and elderly people, and patients with KOA usually suffer from joint pain and dyskinesia, which is disabling and seriously affects their quality of life. Acupotomy therapy, as one of the characteristic treatments of traditional Chinese medicine, has been proven to significantly reduce the pain of KOA patients and effectively slow down the rapid deterioration of the disease. Therefore, this article reviews the pathogenic factors of KOA and explores the mechanism of action of acupotomy therapy for KOA from the perspectives of mechanical structure, level of inflammatory factors, cartilage repair, and cellular autophagy and apoptosis, in order to provide a more solid theoretical basis and therapeutic strategy for the application of acupotomy therapy in the clinical practice of KOA.
Objective To conclude the research progress of unicompartmental knee arthroplasty (UKA) in the treatment of elderly patients with knee osteoarthritis (KOA). Methods The literature on UKA at home and abroad in recent years was reviewed to summarize the clinical characteristics of elderly patients with KOA, perioperative management (including evaluating indications preoperatively, intraoperative prosthesis selection, postoperative complication management, etc). Results Through reasonable preoperative evaluation, prosthesis selection, and advanced perioperative management, for elderly patients with KOA who meet the indications, UKA can be considered. Compared with total knee arthroplasty, the incidence of postoperative complications in elderly patients undergoing UKA is lower, joint awareness is reduced, functional improvement and satisfaction are higher. Meanwhile, choosing appropriate prostheses and fixation methods can lead to a good survival rate. ConclusionUKA can provide a safe and effective treatment option for elderly patients with KOA within a certain range of indications.
Objective To investigate the correlation of elderly knee osteoarthritis with bone marrow edema and osteoprotegerin, DKK-1 (dickkopf-1), sclerostin. Methods A total of 100 elderly patients with knee osteoarthritis in Sichuan Province Orthopedic Hospital from September 2017 to December 2018 were selected and divided into bone marrow edema group (50 cases) and non-bone marrow edema group (50 cases). The patients’ basic data, Western Ontario and McMaster University Osteoarthritis Index (WOMAC) scores and Visual Analogue Scale scores were collected. The patients’ serum osteoprotegerin, DKK-1, sclerostin, C-reactive protein, and erythrocyte sedimentation rate were tested, and the differences between the two groups were compared. The correlation of the detection indicators and bone marrow edema and its clinical indicators was explored. Results There was no significant difference in age, gender, course of disease, C-reactive protein and erythrocyte sedimentation rate between the two groups (P>0.05). WOMAC scores (76.1±5.4 vs. 67.5±6.6), Visual Analogue Scale scores (8.4±1.1 vs. 5.5±0.9), proportion of synovitis (84.0% vs. 52.0%), osteoprotegerin [(1.3±1.1) vs. (0.6±0.5) μg/L], DKK-1 [(18.4±16.9) vs. (6.9±6.0) μg/L] and sclerostin [(147.3±119.4) vs. (99.7±70.7) pg/mL] in the bone marrow edema group were higher than those in the non-bone marrow edema group (P<0.05). There was no statistically significant correlation of the bone marrow edema volume score and degree score and serum osteoprotegerin of patients in the bone marrow edema group (P>0.05). The bone marrow edema volume score and degree score of patients in the bone marrow edema group were positively correlated with serum DKK-1 (volume score rs=0.464, P=0.001; degree score rs=0.379, P=0.007) and sclerostin (volume score rs=0.316, P=0.025; degree score rs=0.461, P=0.003). Conclusion In elderly patients with knee osteoarthritis and bone marrow edema, the local bone metabolism indicators of osteoprotegerin, DKK-1 and sclerostin are up-regulated, especially DKK-1 and sclerostin are related to the severity of bone marrow edema.
Objective To compare the mid- and long-term effectiveness of patellar resurfacing versus non-resurfacing in primary total knee arthroplasty (TKA). Methods Twenty-six patients who underwent bilateral TKA between March 2013 and September 2015 were selected as the study subjects. One side was randomly chosen for patellar resurfacing (resurfacing group), and the other side was not (control group). There were 4 males and 22 females, the age ranged from 51 to 65 years, with an average of 59 years. According to Kellgren-Lawrence classification, there were 21 cases of grade Ⅳ and 5 cases of grade Ⅲ in both knees. There was no significant difference in the surgical side, and preoperative clinical and functional scores of the Knee Society Score (KSS), visual analogue scale (VAS) score, and the composition ratio of anterior knee pain localization points between the two groups (P>0.05). The operation time, intraoperative blood loss, postoperative abnormal signs such as patellar clunk, feeling of constraint, patellar tendon weakness, crepitus, or snow-on-glass sensation, and the occurrence of complications were recorded and compared. Patient subjective evaluations included Forgotten Joint Score (FJS) and the degree of difficulty in high-level knee activities (including flexion with load bearing, going upstairs, going downstairs, squatting and standing up, kneeling, knee extension, and crossing legs for 7 items); KSS clinical/functional scores and VAS scores were used to evaluate the recovery of knee joint function, and the location of anterior knee pain was determined by a localization diagram. Results The operation time of the resurfacing group was significantly longer than that of the control group (P<0.05), and there was no significant difference in intraoperative blood loss between the two groups (P>0.05). All patients’ incisions healed by first intention; the hospital stay ranged from 8 to 23 days, with an average of 12.6 days. All patients were followed up 9-11 years, with an average of 9.7 years. Except for 1 case who died of multiple organ failure due to internal diseases at 9 years after operation and 5 cases with incomplete radiological data, the rest 20 patients were assessed radiologically and found that 1 side of the knee joint in the control group had patellar dislocation; the remaining patients had no prosthetic failure (fracture, loosening, displacement, etc.), patellar fracture, patellar necrosis, patellar instability, patellar tendon rupture, prosthetic revision, etc. No patients had reoperations due to patellar-related complications or anterior knee pain in both knee joints. At 2 years postoperatively and at last follow-up, there was no significant difference in the incidence of abnormal signs such as patellar clunk, feeling of constraint, patellar tendon weakness, crepitus, or snow-on-glass sensation, the incidence of high-level knee activity difficulty, and the composition ratio of anterior knee pain localization between the two groups (P>0.05). The KSS clinical scores, functional scores, and VAS scores of both groups significantly improved compared to preoperative ones (P<0.05); there was no significant difference in the comparison between the two groups at the two time points postoperatively (P>0.05). At 2 years postoperatively and at last follow-up, there was no significant difference in FJS scores between the two groups (P>0.05). ConclusionPatellar resurfacing or not has similar mid- and long-term effectiveness in primary TKA.
ObjectiveTo explore the safety and effectiveness of Taylor spatial frame (TSF) in the treatment of medial compartmental osteoarthritis (MCOA) of the knee and the adjustment of the lower extremity force line at the same time.MethodsThe clinical data of 30 patients with MCOA who underwent high tibial osteotomy (HTO) between October 2016 and April 2017 were retrospectively analyzed. According to the different fixation methods, they were divided into external fixation group (TSF external fixation, 16 cases) and internal fixation group (locking steel plate internal fixation, 14 cases). There was no significant difference between the two groups in gender, age, side, disease duration, mechanical femur tibia angle (MFTA), and other general data (P>0.05). The operation time and intraoperative blood loss of the two groups were recorded and compared; MFTA was used to evaluate the recovery of the lower extremity force line at last follow-up; Hospital for Special Surgery (HSS) score was used to evaluate the clinical effecacy before operation and at 2 weeks, 1 month, and 3 months after operation.ResultsThe operation time and intraoperative blood loss of external fixation group were significantly less than those of internal fixation group (P<0.05). All patients were followed up 9-16 months, with an average of 12 months. There were 2 cases of delayed healing in the internal fixation group and 1 case of delayed healing in the external fixation group, and all healed after symptomatic treatment. All patients in the two groups had no complication such as needle infection, nonunion at osteotomy, osteomyelitis, and so on. At last follow-up, MFTA standard was used to evaluate the recovery of force line. The results of external fixation group were all excellent, while the results of internal fixation group were excellent in 10 cases and good in 4 cases. The difference between the two groups was significant (Z=–2.258, P=0.024). The HSS scores in the two groups were significantly improved at each time point after operation, and gradually improved with time after operation (P<0.05). The HSS score of the external fixation group was significantly higher than that of the internal fixation group (t=2.425, P=0.022) at 3 months after operation; and there was no significant difference between the two groups at other time points (P>0.05).ConclusionTSF has unique advantages in HTO treatment of MCOA patients and correction of lower extremity force line, such as shorter operation time, less bleeding, firm fixation, and less complications. It can accurately adjust the lower extremity force line after operation and has good effectiveness. It is an effective and safe fixation method.
