RESUMO
Joint contracture causes distressing permanent mobility disorder due to trauma, arthritis, and aging, with no effective treatment available. A principal and irreversible cause of joint contracture has been regarded as the development of joint capsule fibrosis. However, the molecular mechanisms underlying contracture remain unclear. We established a mouse model of knee joint contracture, revealing that fibrosis in joint capsules causes irreversible contracture. RNA-sequencing of contracture capsules demonstrated a marked enrichment of the genes involved in the extracellular region, particularly periostin (Postn). Three-dimensional magnetic resonance imaging and immunohistological analysis of contracture patients revealed posterior joint capsule thickening with abundant type I collagen (Col1a2) and POSTN in humans. Col1a2-GFPTG ; Postn-/- mice and chimeric mice with Col1a2-GFPTG ; tdTomatoTG bone marrow showed fibrosis in joint capsules caused by bone marrow-derived fibroblasts, and POSTN promoted the migration of bone marrow-derived fibroblasts, contributing to fibrosis and contracture. Conversely, POSTN-neutralizing antibody attenuated contracture exacerbation. Our findings identified POSTN as a key inducer of fibroblast migration that exacerbates capsule fibrosis, providing a potential therapeutic strategy for joint contracture.

PURPOSE: The primary objective of this study was to compare the long-term survival rates of silicone metacarpophalangeal (MCP) arthroplasties between two major implants in patients with rheumatoid arthritis, using implant fracture as an end point. We also evaluated the difference in postoperative function between patients with fractured and intact implants as a secondary objective. METHODS: A retrospective cohort study was conducted on 372 fingers of 133 hands that underwent silicone MCP arthroplasty between January 2000 and June 2019 (mean follow-up, 7.6 years). The survival rates of Swanson-type and Sutter-type implants were compared, using implant fracture as the end point after a radiographic evaluation. Clinical measures and upper limb functional assessments using the Disabilities of the Arm, Shoulder, and Hand (DASH) score were performed in the nested cohort. RESULTS: The 10.6-year survival rates for implant fracture of Swanson- and Sutter-type implants were 86.2% and 9.4%, respectively, with significantly higher survival noted for Swanson-type implants. The Sutter-type implant showed increased susceptibility to fracture in all four fingers compared to the Swanson-type implant. Implant fractures were primarily observed at the stem-hinge junction. There were no significant differences in upper limb function between the fractured and intact implant groups. CONCLUSIONS: Sutter-type implants were found to be more prone to fracture compared with Swanson-type implants. However, implant fractures did not significantly affect upper limb function. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognosis IV.

INTRODUCTION: Medial closed-wedge distal femoral osteotomy (MCWDFO) is a valuable treatment approach for lateral knee osteoarthritis with femoral valgus deformity. Improved results have been reported with the upgrade of surgical techniques and locking plates. However, the risk of nonunion and loss of correction increases in cases of lateral hinge fractures. This study aimed to evaluate the mechanical impact of hinge fractures and support instruments in MCWDFO using finite element analysis (FEA). MATERIALS AND METHODS: Five femur models were developed using Mechanical Finder 11.0 FEA software. We simulated the following models: only a medial locking plate (MLP) (group A); an MLP with a lateral support screw (group B); and an MLP with a lateral support plate (group C). The equivalent stress around the hinge was evaluated and the percentage of the plastic deformation zone was calculated for the hinge area in the no-hinge fracture model. The equivalent stress of the MLP and the degree of displacement were calculated using the hinge fracture model. RESULTS: The percentages of the plastic deformation zone in groups A, B, and C were 18.0 ± 11.7%, 3.3 ± 2.4%, and 2.3 ± 2.8%, respectively. The percentages tended to be lower in groups B and C than in group A. In the hinge fracture model, the mean equivalent stress of the MLP in group C was significantly less than that in group A. In terms of the mean degree of displacement, group A showed more than 1 mm of displacement, which was significantly larger than that of the other groups. CONCLUSION: The support instruments provided stability to the hinge site and reduced the equivalent stress of the main plate in the MCWDFO with hinge fractures. No significant difference was observed between the two instruments in terms of stability.

OBJECTIVES: The purpose of this study was to examine the reproducibility of vertical subluxation (VS) parameters using X-ray, computed tomography (CT), and tomosynthesis (TS) while comparing the head-loading effects. METHODS: The VS parameters of 26 patients (retrospective review) were evaluated. Using the intra-class correlation coefficient, we statistically examined the intra-rater and inter-rater reliabilities of the parameters. Head-loaded and -unloaded imagings were compared using a Wilcoxon signed-rank test. RESULTS: The intra-rater reliability of TS and CT showed intra-class correlation coefficients of ≥0.8 (X-ray range: 0.6-0.8), with similar results for the inter-rater reliabilities. Furthermore, in head-loading imaging, the TS had significantly higher VS scores than that of CT (P < .05). CONCLUSIONS: In comparison with the X-ray, TS and CT were more accurate and reproducible. In terms of head loading, the VS values for TS were worse than those for CT, indicating that TS was more effective than CT in diagnosing VS.

OBJECTIVES: To investigate the effects of intensive treatment on joint damage in patients with rheumatoid arthritis (RA) showing progression of joint damage and low disease activity or remission. METHODS: Eighty-nine patients who had change in the van der Heijde modified total Sharp score (TSS) of >0.5 points at baseline when compared with the score 1 year ago were enrolled and categorized into two groups to receive intensive (intensive group) or current (current group) treatment. The intensive and current groups were compared for change (Δ) from baseline to 1 year of erosion score, joint space narrowing score, and TSS. RESULTS: The ΔTSS values at 1 year in the intensive and current groups were 0.67 ± 1.09 and 1.79 ± 1.70, respectively (P < 0.001). In the intensive and current groups, the ΔTSS ≤ 0.5 at 1 year were 66.7% and 32.4%, respectively (P = 0.010). CONCLUSIONS: The intensive treatment was more effective at suppressing joint damage than the current treatment. The progression of joint damage is an important target to consider for intensive treatment.

OBJECTIVES: Foot and ankle impairments are major issues in patients with rheumatoid arthritis (RA). Foot deformities often lead to skin disorders, such as callosities, ingrown toenails, and interdigital tinea pedis. This study was aimed at investigating the efficacy and limitations of foot care by experts in patients with RA. METHODS: Thirty-one patients with RA who began receiving foot care from nurses at our institution between September 2020 and February 2023 were included. Responses to a survey using the self-administered foot evaluation questionnaire (SAFE-Q) for patient-reported outcome measures were compared at baseline, the second visit (1.3 ± 0.5 months after baseline), and the third visit (3.6 ± 1.6 months after baseline). RESULTS: Scores for 'Pain and pain-related' and 'General health and well-being' components of SAFE-Q markedly improved after foot care. On the other hand, there were no significant differences in the scores for 'Physical functioning and daily living', 'Social functioning', and 'Shoe-related' components during observation periods. CONCLUSIONS: Foot care for rheumatoid feet is effective in providing pain relief and improving general health and well-being. However, physical and social functioning and footwear issues did not improve. Clinicians must understand the effects and limitations of foot care in patients with RA.
RESUMO
Romosozumab can increase bone mineral density (BMD) in patients with osteoporosis, but some patients do not respond to it. This study aimed to identify risk factors for being a nonresponder to romosozumab treatment. This retrospective observational study included 92 patients. Romosozumab (210 mg) was subcutaneously administered to the participants every 4 weeks over 12 months. We excluded patients who previously underwent treatment for osteoporosis to assess the impact of romosozumab alone. We evaluated the proportion of patients who did not respond to romosozumab treatment to the lumbar spine and hip with increased BMD. Nonresponders were defined as those with a bone density change of < 3% after 12 months of treatment. We compared demographics and biochemical markers between responders and nonresponders. We found that 11.5% of patients were nonresponders at the lumbar spine, and 56.8% were nonresponders at the hip. A risk factor for nonresponse at the spine was low type I procollagen N-terminal propeptide (P1NP) values at 1 month. The cutoff value for P1NP at month 1 was 50 ng/ml. We found that 11.5% and 56.8% of patients experienced no significant improvement in the lumbar spine and hip BMD, respectively. Clinicians should use nonresponse risk factors to inform decisions about romosozumab treatment for patients with osteoporosis.

INTRODUCTION: Once-daily teriparatide (D-TPTD) and twice-weekly TPTD (W-TPTD), which are self-administered injections, are generally used in the treatment of severe osteoporosis. This study aimed to reveal the differences in the persistence, safety, and effectiveness of D-TPTD and W-TPTD. MATERIALS AND METHODS: A total of 102 patients received D-TPTD (n = 51) and W-TPTD (n = 51). The bone mineral densities (BMD) of the lumbar spine, total hip, and femoral neck were measured using dual energy X-ray absorptiometry. The persistence and effectiveness of the two treatments were compared at 12 months. RESULTS: The persistence in the D-TPTD and W-TPTD groups was 80.4% and 66.7% at 12 months, respectively (p = 0.178). The % changes (Δ) in BMD values from baseline for the lumbar spine in the D-TPTD were significantly higher than those in the W-TPTD (11.2% vs. 6.3%; p < 0.001) at 12 months. The ΔBMD values for the total hip (3.7% vs. 1.3%; p = 0.065) and femoral neck (2.2% vs. 1.6%; p = 0.489) did not differ significantly between the two groups at 12 months. The incidence of new morphological vertebral fractures in the D-TPTD and W-TPTD groups was 7.3% and 8.6%, respectively, at 12 months (p = 1.000). CONCLUSIONS: Lumbar spine BMD (LS-BMD) was significantly increased. Moreover, ΔLS-BMD in the D-TPTD group was higher than that in the W-TPTD group. This study showed that the persistence, ΔTH-BMD, ΔFN-BMD and incidence of vertebral fractures did not differ between the two groups.

BACKGROUND: Although the importance of kinematic evaluation of the sit-to-stand (STS) test of total knee arthroplasty (TKA) patients is clear, there have been no reports analyzing STS during the 30-s chair sit-up test (30 s-CST) with a focus on kinematic characteristics. This study aimed to demonstrate the clinical utility of kinematic analysis of STS during the 30 s-CST by classifying STS into subgroups based on kinematic parameters, and to determine whether differences in movement strategies are expressed as differences in clinical outcomes. METHODS: The subjects were all patients who underwent unilateral TKA due to osteoarthritis of the knee and were followed up for one year postoperatively. Forty-eight kinematic parameters were calculated using markerless motion capture by cutting STS in the 30 s-CST. The principal components of the kinematic parameters were extracted and grouped by kinematic characteristics based on the principal component scores. Clinical significance was examined by testing whether differences in patient-reported outcome measures (PROMs) were observed. RESULTS: Five principal components were extracted from the 48 kinematic parameters of STS and classified into three subgroups (SGs) according to their kinematic characteristics. It was suggested that SG2, using a kinematic strategy similar to the momentum transfer strategy shown in previous studies, performed better in PROMs and, in particular, may be associated with achieving a "forgotten joint", which is considered the ultimate goal after TKA. CONCLUSIONS: Clinical outcomes differed according to kinematic strategies used STS, suggesting that kinematic analysis of STS in 30 s-CST may be useful in clinical practice. TRIAL REGISTRATION: This study was approved by the Medical Ethical Committee of the Tokyo Women's Medical University (approval number: 5628 on May 21, 2021).

PURPOSE: The relationship between ligament remnant quality and postoperative outcomes after arthroscopic lateral ankle ligament repair for chronic lateral ankle instability is controversial. This study aimed to determine whether the signal intensity of the anterior talofibular ligament on preoperative magnetic resonance imaging and ligament remnant quality identified on arthroscopy are associated with recurrent ankle instability after arthroscopic lateral ankle ligament repair. METHODS: A total of 68 ankles from 67 patients with chronic lateral ankle instability who underwent arthroscopic lateral ankle ligament repair were retrospectively studied. The signal intensity of the anterior talofibular ligament was evaluated using T2-weighted magnetic resonance imaging. Arthroscopy was used to evaluate the thickness and mechanical resistance of the anterior talofibular ligament by hook palpation and to classify ankles into two groups: the present anterior talofibular ligament group with adequate mechanical resistance and the absent anterior talofibular ligament group with no mechanical resistance. The outcomes included recurrent ankle instability (respraining of the operated ankle after surgery) and Self-Administered Foot Evaluation Questionnaire scores. RESULTS: Thirteen ankles were diagnosed with recurrent ankle instability. Patients with a high anterior talofibular ligament T2 signal intensity experienced more recurrent ankle instability than those with a low intensity. As determined via arthroscopy, the absent anterior talofibular ligament group had a higher rate of recurrent ankle instability than the present anterior talofibular ligament group. There were no significant differences in Self-Administered Foot Evaluation Questionnaire scores between patients with high and low anterior talofibular ligament T2 signal intensity, as well as between absent and present anterior talofibular ligament groups based on arthroscopy. CONCLUSION: Poor quality of the anterior talofibular ligament remnant could result in recurrent ankle instability after arthroscopic lateral ankle ligament repair. Therefore, when treating chronic lateral ankle instability, surgeons should consider ligament quality. LEVEL OF EVIDENCE: IV.

PURPOSE: This study aims to compare the effect of using O-arm and C-arm fluoroscopy on the surgical outcomes of occipitocervical fixation. METHODS: The study included patients who underwent occipitocervical fixation using O-arm or C-arm between 2005 and 2021. Of 56 patients, 34 underwent O-arm-assisted surgery (O-group) and 22 underwent C-arm-assisted surgery (C-group). We assessed surgical outcomes, including operative time, intraoperative blood loss, perioperative complications, and bone union. RESULTS: Almost half of the patients had rheumatoid arthritis-related disorders in both groups. Sixteen cases (47.1%) in the O-group and 12 cases (54.5%) in the C-group were fixed from occipito (Oc) to C3, 12 cases (38.2%) in the O-group and 7 cases (31.8%) in the C-group from Oc to C4-7, 5 cases (14.7%) in the O-group, and 3 cases (13.6%) in the C-group from Oc to T2 (p = 0.929). There was no significant difference in operative time (p = 0.239) and intraoperative blood loss (p = 0.595) between the two groups. Dysphagia was the most common complication in both groups (O-group vs. C-group, 11.7% vs. 9.1%). Regarding implant-related complications, occipital plate dislodgement was observed in four cases (18.2%) in the C-group (p = 0.02). The bone union rate was 96.3% in the O-group and 93.3% in the C-group (P = 1). CONCLUSIONS: O-arm use is associated with a reduced rate of occipital plate dislodgment and has a similar complication incidence compared with C-arm-assisted surgery and does not prolong operative time despite the time needed for setting and scanning. Accordingly, an O-arm is safe and useful for occipitocervical fixation surgery.
RESUMO
BACKGROUND: Intra-articular administration of adipose tissue-derived stem cells (ADSC) is an alternative treatment option for knee osteoarthritis (OA) after conventional treatment fails; however, the clinical results related to the severity of OA grade and changes of cartilage volumes after the administration of ADSC is unknown. This study aimed to determine 1) clinical outcomes after the ADSC administration in knee OA with consideration of radiographic OA grades and 2) changes in cartilage volumes after ADSC administration. METHODS: This observational study included 86 knees from 51 patients who underwent intra-articular administration of cultured ADSC; 47 patients (80 knees) completed follow-up for 6 months (follow-up rate: 93%). The Knee injury and Osteoarthritis Outcome Scores (KOOS) were reported at baseline and 1, 3, and 6 months after the administration. The efficacy rate in the Outcome Measures in Arthritis Clinical Trials-Osteoarthritis Research Society International (OMERACT-OARSI) was evaluated using the KOOS. Cartilage volume of the knee joint was measured using quantitative 3-dimensional magnetic resonance imaging (3D-MRI) software at baseline and 6 months in 52 knees in 31 patients (follow-up rate: 61%). RESULTS: All items on the KOOS except "sports/recreation" improved significantly at 6 months with more significance in knees with a Kellgren-Lawrence (KL) grade 2 or 3 compared with KL grade 4 knees. The OMERACT-OARSI responder at 6 months was significantly greater in knees with KL grade 2 or 3 (64%) than in knees with KL grade 4 (42%, p = 0.045). Cartilage volume changes varied among patients and were not related to the changes in KOOS after ADSC administration. CONCLUSIONS: Intra-articular administration of ADSC in knee OA improved KOOS at 6 months. The effects were more significant in knees with KL grade 2 or 3 than with KL grade 4. Changes in KOOS were not related to change in cartilage volumes after ADSC administration.

INTRODUCTION: Several prognostic factors for survival in synovial sarcoma have been proposed, but the role of adjuvant chemotherapy and radiotherapy is a matter of debate. The study aim was to clarify the effect of high-dose ifosfamide-containing chemotherapy and adjuvant radiotherapy for patients with localized synovial sarcoma. MATERIALS AND METHODS: Five tertiary musculoskeletal oncology hospitals participated in this retrospective study. The records of the patient diagnosed with synovial sarcoma without metastasis at diagnosis from 1990 to 2011 have been collected and reviewed. Overall, distant failure-free, and local failure-free survivals were calculated, and prognostic factors for each survival were evaluated by performing univariate and multivariate analyses. RESULTS: A total of 162 patients were enrolled in this study with a median follow-up period of 67 months (range, 5-267 months) for all surviving patients. The 5-year overall, distant failure-free, and local failure-free survival rates were 79.7%, 66.3%, and 98.4%, respectively. Univariate analyses demonstrated that high-dose ifosfamide-containing chemotherapy was significantly associated with better overall (p = 0.014) and distant failure-free survival (p = 0.0043) than that of low-dose or no ifosfamide-containing chemotherapy if we analyzed only patients with tumors >5 cm in size. Addition of radiotherapy was not a significant prognostic factor for overall survival in the univariate and multivariate analyses, but it did improve the overall survival of the patients with R1 resection (p = 0.053). CONCLUSION: Patients with localized synovial sarcoma >5 cm in size had better overall and distant failure-free survival after receiving adjuvant chemotherapy containing high-dose ifosfamide comparing to low-dose or no ifosfamide-containing chemotherapy. The addition of adjuvant radiotherapy was beneficial for the patients who received R1 resection. Alternatively, adjuvant radiotherapy could be avoided for patients who achieved an R0 margin.

OBJECTIVES: Operative procedures for rheumatoid forefoot deformities have gradually changed from arthrodesis or resection arthroplasty to joint-preserving surgery. Although joint-preserving arthroplasty has yielded good outcomes, painful plantar callosities may occur post-operatively. This study aimed to reveal the radiographic factors associated with painful callosities after joint-preserving surgery for forefoot deformities in patients with rheumatoid arthritis (RA). METHODS: We retrospectively evaluated 166 feet in 133 patients with RA who underwent forefoot joint-preserving arthroplasty, including proximal rotational closing-wedge osteotomies of the first metatarsal, between January 2012 and December 2015. Logistic regression analysis was performed with the objective variable set as the presence/absence of painful plantar callosities at the final observation and the explanatory variables set as several radiographic factors, including post-operative relative first metatarsal length (RML), amount of dorsal dislocation of the fifth metatarsal (5DD), and arc failure of the lesser toes. RESULTS: At the final follow-up, 42 of the 166 feet (25.3%) had painful callosities under the metatarsal heads post-operatively. Logistic regression analysis showed that the RML, 5DD, and lesser toes' arc failure were significantly associated with painful callosities. CONCLUSIONS: We identified that RML, 5DD, and arc failure of the lesser toes were associated with painful plantar callosities after the surgery.

OBJECTIVES: To investigate the effect of romosozumab versus denosumab treatment on bone mineral density (BMD), disease activity, and joint damage in patients with rheumatoid arthritis and severe osteoporosis. METHODS: Fifty-one postmenopausal women were enrolled and randomized equally into two groups to receive either romosozumab or the denosumab. Changes (Δ) in the BMD (at lumbar spine, total hip, and femoral neck), disease activity score in 28 joints (DAS28)-erythrocyte sedimentation rate (ESR), and van der Heijde-modified Total Sharp Score (TSS) from baseline to 12 months after treatment were evaluated. RESULTS: The ΔBMD at 12 months in the romosozumab and denosumab groups were 10.2 ± 5.6% and 5.0 ± 3.1% (p = .002) for the lumbar spine, 3.7 ± 4.9% and 3.5 ± 3.0% (p = .902) for the total hip, and 3.6 ± 4.7% and 3.2 ± 4.9% (p = .817) for the femoral neck, respectively. The ΔDAS28-ESR and ΔTSS at 12 months did not differ between these two groups. CONCLUSIONS: Our results suggest that romosozumab treatment was more effective in increasing the BMD at the lumbar spine than denosumab and may be selected for patients who require a significant increase in the lumbar spine BMD.

OBJECTIVES: A global downward trend in the number of rheumatoid arthritis (RA)-related surgeries has been reported. The purpose of our study was to investigate the latest trends in RA-related surgeries in a single-centre Japanese RA cohort. METHODS: This study was a retrospective analysis of RA-related surgeries between 2001 and 2020 in the Institute of Rheumatology Rheumatoid Arthritis cohort. An average of 4944 patients per semi-annual survey was included in the study. The primary goal was to analyse the half-year period prevalence proportion (HPP) of RA-related surgeries in a 20-year period, and the secondary goal was to analyse the HPP of surgeries by site or by categories of disease activity. RESULTS: There has been a downward trend in the HPP of RA-related surgeries in the 20-year study period. The total HPP of RA-related surgeries decreased by 50.3% during the 20-year study period. There was a significant decrease in knee, hip, shoulder/elbow, and hand procedures. Only foot/ankle joint surgeries significantly increased in volume during this period (p = .001). The HPP of RA-related surgeries remained unchanged in patients with remission or low disease activity. CONCLUSIONS: The number of RA-related surgeries decreased over a 20-year period, but foot/ankle joint surgeries increased in the site-specific evaluation.

OBJECTIVES: The purpose of the present study was to evaluate improvement in the Knee Injury and Osteoarthritis Outcome Score (KOOS) after open-wedge high tibial osteotomy (HTO) in comparison with total knee arthroplasty (TKA) in cohorts over age 60 matched by pre-operative age, gender, body mass index (BMI), hip-knee-ankle angle (HKAA), KOOS sub-scores, and osteoarthritis (OA) grade. METHODS: Propensity score matching was performed between 162 HTO patients and 134 TKA patients. When calculating the propensity score by multivariate logistic regression analysis, the following pre-operative confounders were included: age, gender, BMI, HKAA, KOOS sub-scores, and OA grade. Consequently, a total of 55 patients were included in each group. The Student's t-test was used to analyse differences in the post-operative KOOS sub-scores between groups. RESULTS: After propensity score matching, all matched pre-operative valuables were identical, with no significant differences between the HTO and TKA groups. None of the post-operative KOOS sub-scores at 1 year after surgery showed a significant difference between the HTO and TKA groups. Both groups demonstrated significant and comparable post-operative improvement in every KOOS sub-score. CONCLUSIONS: In patients over age 60, there was no significant difference in short-term pain relief and improvements in activity and quality of life between HTO and TKA after propensity score matching including pre-operative age, KOOS sub-scores, and OA grade. HTO is a joint preservation procedure that is valid for knee OA even in individuals over age 60.

OBJECTIVES: The concept of locomotive syndrome (LS) and its evaluation method, the LS risk test, have been applied in an integrated manner to capture the decline in mobility resulting from musculoskeletal disorders. The purpose of this study was to evaluate the impact of total knee arthroplasty (TKA) in the elderly with knee osteoarthritis, a common disorder found in LS. METHODS: A total of 111 patients were registered prior to TKA and postoperatively followed up for 1 year. Three components of the LS risk test (the two-step test, stand-up test, and Geriatric Locomotive Function Scale-25) were assessed pre- and postoperatively. RESULTS: After surgery, all three components of the test showed significant improvements from the baseline. The ratio of Stage 3 LS patients (progressed stage of decrease in mobility) reduced from 82.3% to 33.9% postoperatively. There was no significant difference in the degree of change in the scores between the younger (60-74 years) and older (≥75 years) age groups. CONCLUSIONS: We found that TKA has a major impact in preventing the progression of LS in patients with knee osteoarthritis. The LS risk test is a feasible tool for the longitudinal evaluation of patients with musculoskeletal diseases of varying severity and with multiple symptoms.

[Purpose] The present study aimed to determine the effectiveness of locomotion training on physical function and quality of life in patients with rheumatoid arthritis (RA) and identify factors associated with its effectiveness. [Participants and Methods] Data were obtained from 103 patients with rheumatoid arthritis who underwent locomotion training for 6 months using the Health Assessment Questionnaire Disability Index, pain visual analog scale, 10-meter walking speed, timed up-and-go test, single-leg standing time, grip strength, 25-question Geriatric Locomotive Function Scale, Short Form-8, fat-free mass index, and fat mass index. [Results] A significant improvement in the Health Assessment Questionnaire Disability Index, pain visual analog scale score, maximum 10-meter walking speed, timed up-and-go test, single-leg standing time, grip strength, and physical component summary in Short Form-8 was observed at six months. [Conclusion] The current study demonstrated that locomotion training for 6 months improved physical function, certain aspects of quality of life, and sarcopenia in patients with RA. We believe that locomotion training should be recommended as a non-pharmacological therapeutic option for improving physical function in patients with RA.
RESUMO
BACKGROUND: Knee replacement is a very effective and indispensable treatment option for end-stage knee arthritis, and the number of cases has been increasing worldwide. A replaced knee joint without patient joint awareness is thought to be the ultimate goal of artificial knees. Joint awareness reportedly correlates with patient satisfaction. Although numbness around a replaced knee is a minor but common problem, its effect on postoperative outcome is controversial. Joint awareness also is sensitive to subtle abnormalities of the joint, so it must be negatively affected by numbness. Although numbness is minor, it cannot be ignored to further improve knee replacement outcomes. This study investigated the relationship between patient-reported numbness and other patient-reported outcome measures (PROMs), including joint awareness, and kneeling. We developed a numbness score based on a 5-point Likert scale on frequency of numbness, with an intraclass correlation coefficient of 0.76 and higher scores indicating less numbness. METHODS: The numbness score, New Knee Society Score (KSS), Knee Injury and Osteoarthritis Outcome Score (KOOS), Forgotten Joint Score-12 (FJS-12), and other clinical and radiological data from 311 patients (394 primary knee replacements) were analyzed. Kneeling ability was evaluated by using kneeling-specific items in the KSS (KSS-Kneeling). RESULTS: No numbness was found in 170 knees (43.1%), and some degree of numbness was found in the remaining 224 knees (56.9%). The numbness score showed weak-to-moderate correlations with KSS-Symptoms (r = 0.44), KSS-Satisfaction (r = 0.41), KSS-Activities (r = 0.29), and all KOOS subscales (r = 0.23-0.44), and FJS-12 (r = 0.42). Multiple regression analyses suggested that midline incision positively affected the numbness score over the anteromedial incision (p = 0.04) and that a better numbness score (p = 0.001), male sex (p < 0.0001), and better postoperative knee flexion angle (0.04) positively affected kneeling. CONCLUSIONS: The numbness score positively correlated with PROMs and positively affected kneeling. Knee replacements performed via an anteromedial incision may be at higher risk for numbness.
