RESUMO

Background and Objectives: A reduction forced toward the posterior side during graft fixation may help to lessen anterior tibial translation after ACL reconstruction. The purpose was to compare the clinical and radiological outcomes of graft fixation when a posterior draw was used and when it was not used during anterior cruciate ligament (ACL) reconstruction surgery. Materials and Methods: Of 110 patients who had undergone primary arthroscopic ACL reconstruction between January 2017 and August 2020, in all, 76 patients had been operated on without a posterior draw (non-draw group), and 34 patients had received surgery with a posterior draw (draw group). The results of the Lachman test and the pivot-shift test, the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) indexes, the Lysholm scores, the International Knee Documentation Committee (IKDC) subjective scores, and side-to-side difference (STSD) on stress radiography were compared between the two groups. Results: The postoperative WOMAC indexes, Lysholm scores, and IKDC subjective scores were similar across both groups. Postoperative STSD (2.4 ± 2.2 for the non-draw group vs. 2.0 ± 2.2 for the draw group; p = 0.319) and change in STSD (3.5 ± 3.5 for preoperative STSD vs. 4.3 ± 4.4 for postoperative STSD; p = 0.295) were not superior in the draw group. Conclusions: The take-home message is that graft fixation with a posterior draw during ACL reconstruction did not result in significantly better postoperative stability. The postoperative clinical outcomes were similar between both groups.

RESUMO

BACKGROUND: A composite graft is considered the best choice for facial reconstruction because of proper texture, color, and simple surgical techniques. However, due to revascularization by the bridging phenomenon, it has limitations with unpredictable survival rates and can be applied only to small defects. Polydeoxyribonucleotide (PDRN) plays an important role in multiple vascular processes such as angiogenesis via production of a vascular endothelial growth factor and by providing an anti-inflammatory effect by reducing pro-inflammatory cytokines through the adenosine A2 receptor stimulation. Thus, here, we investigated PDRN as a supportive method to improve survival of composite grafts. METHODS: Chondrocutaneous composite grafts were applied to both ears of 20 New Zealand White rabbits. The grafts were then rotated and returned to their positions to prevent the original blood flow from the base of the grafts. On postoperative days 1, 3, 6, 9, and 12, PDRN was injected intradermally into the experimental group (20 ears) and normal saline was injected into the control group (20 ears) to exclude bias of pressure effect. After 12 days, graft survival and cutaneous blood flow were examined under laser speckle contrast imaging. RESULTS: Gross observation indicated that the graft viability in the PDRN group was significantly higher than that in the control group (p < 0.05). Through laser speckle contrast imaging, signal intensity increased from the periphery and progressed centrally with treatment. CONCLUSION: Our findings suggest that PDRN may increase blood flow around at the base of the graft, restore the perfusion, and improve the survival of the composite grafts.

RESUMO

[Purpose] To present an efficient treatment regimen for patients with cervicogenic headache by comparatively analyzing the neck disability index (NDI) and cervical muscle activity after an exercise intervention. [Participants and Methods] Thirty patients with cervicogenic headache were assigned to the cranio-cervical flexion group (n=15) and cranio-cervical flexion plus transcranial direct current stimulation (tDCS) group (n=15). Intervention was administered for four weeks, after which the participants' NDI and sternocleidomastoid muscle activity were measured. [Results] The treatment group demonstrated a significantly greater change in NDI after the intervention compared to the control group. The treatment group also showed a significantly greater change in sternocleidomastoid muscle activity than the control group. [Conclusion] Our results show that applying tDCS during cranio-cervical flexion exercise can strengthen the sternocleidomastoid muscle more effectively while improving pain and associated functions in patients with cervicogenic headache. These results would contribute towards developing a more efficient treatment for patients with cervicogenic headache.

RESUMO

BACKGROUND: Implant survivorship is reported to be lower and complications, particularly bearing dislocation, are reported to be more frequent in Asian than in Western patients with medial knee osteoarthritis (OA) undergoing Oxford® Phase III unicompartmental knee arthroplasty (UKA). To date, however, these complications have not been compared between these groups of patients. QUESTIONS/PURPOSES: The purpose of this study was to perform a meta-analysis comparing the standardized incidence rates of (1) all-cause reoperation; (2) reoperation related to bearing dislocation; and (3) reoperation related to progression of lateral compartment arthritis in Asian and Western patients with medial knee OA who underwent Oxford Phase III UKA. METHODS: We searched MEDLINE® (January 1, 1976, to May 31, 2017), EMBASE® (January 1, 1985, to May 31, 2017), and the Cochrane Library (January 1, 1987, to May 31, 2017) for studies that reported complications of Oxford Phase III UKAs. Studies were included if they reported reoperation rates attributable to bearing dislocation and/or progression of lateral knee OA after surgery with this implant. Twenty-seven studies were included in this systematic review and 16 studies with followups > 5 years were included in the meta-analysis. These rates were converted to standardized incidence rate (that is, reoperations per 100 observed component years) based on mean followup and number of involved knees in each study. After applying prespecified inclusion and exclusion criteria, the studies were categorized into two groups, Asian and Western, based on hospital location. Twenty-five studies, containing 3152 Asian patients and 5455 Western patients, were evaluated. Study quality was assessed by the modified Coleman Methodology score (MCMS). Although all studies were Level IV, their mean MCMS score was 66.92 (SD, 8.7; 95% confidence interval [CI], 63.5-70.3), indicating fair quality. Because the heterogeneity of all subgroup meta-analyses was high, a random-effects model was used with estimations using the restricted maximum likelihood method. RESULTS: There was no difference in the proportion of Asian patients versus Western patients undergoing reoperation for any cause calculated as 100 component observed years (1.022 of 3152 Asian patients; 95% CI, 0.810-1.235 versus 1.300 of 5455 Western patients; 95% CI, 1.067-1.534; odds ratio, 0.7839; 95% CI, 0.5323-1.1545; p = 0.178). The mean reoperation rate attributable to bearing dislocation per 100 observed years was higher in Asian than in Western patients (0.525; 95% CI, 0.407-0.643 versus 0.141; 95% CI, 0.116-0.166; odds ratio, 3.7378; 95% CI, 1.694-8.248; p = 0.001) Conversely, the mean reoperation rate attributable to lateral knee OA per 100 observed years was lower in Asian than in Western patients (0.093; 95% CI, 0.070-0.115 versus 0.298; 95% CI, 0.217-0.379; odds ratio, 0.3114; 95% CI, 0.0986-0.9840; p < 0.001). CONCLUSIONS: Although total reoperation rates did not differ in the two populations, reoperation for bearing dislocation was more likely to occur in Asian than in Western patients, whereas reoperation for lateral knee OA progression was more likely to occur in Western than in Asian patients after Oxford Phase III UKA. Although possible explanations for these findings may be hypothesized, additional randomized, prospective comparative studies are needed. However, better survival outcomes after UKA may require consideration of ethnicity and lifestyle choices in addition to traditional surgical technique and perioperative care. LEVEL OF EVIDENCE: Level III, therapeutic study.

RESUMO

[Purpose] This study aimed to compare and analyze the mechanical properties of the upper cervical muscles in patients with cervicogenic headache to identify efficient methods of treatment and diagnosis. [Subjects and Methods] A total of 40 subjects including 20 healthy individuals and 20 patients with cervicogenic headache were selected. A MyotonPRO device was used to measure the tone (Hz), stiffness (N/m), and elasticity (log decrement) of the suboccipital muscles and upper trapezius of the subjects. [Results] There was no significant difference between the 2 groups in the elasticity of the suboccipital muscles and upper trapezius. However, there was a statistically significant difference in tone and stiffness. [Conclusion] This study showed that the tone and stiffness of the suboccipital muscles and upper trapezius in patients with cervicogenic headache had increased compared to healthy subjects.

RESUMO

[Purpose] This study aims to analyze the factors that affect the quality of life of children with cerebral palsy. [Subjects and Methods] The study subjects were 138 children, aged 7-12, who suffer from cerebral palsy. Factors affecting subjects' quality of life were evaluated using the ICF-CY; quality of life was evaluated using the KIDSCREEN 52 - Health-Related Quality of Life questionnaire. Multiple regression analysis was conducted. [Results] The factors related to physical functions that affect subjects' quality of life were mental function, sensory function and pain, genitourinary and reproductive function, as well as neuromusculoskeletal and movement-related functions. Factors related to activities and participation were learning and applying knowledge, self-care, interpersonal interactions and relationships, major life areas, and community, social and civic life. Lastly, factors related to the environment were products and technology, natural environment and human made changes to environment, and attitude. [Conclusion] In order to improve the quality of life of children with cerebral palsy, the compound effects of several factors should be comprehensively considered without being limited to a specific variable from physical function. And children should be provided with ample opportunities to participate in diverse activities and their physical functions, as well as the environmental factors, should improve.

RESUMO

[Purpose] The purpose of this study was to examine the effect of virtual reality-based eccentric training on lower extremity muscle activity and balance in stroke patients. [Subjects and Methods] Thirty stroke patients participated, with 15 patients allotted to each of two eccentric training groups: one using a slow velocity (group I) and one using a fast velocity (group II). The virtual reality-based eccentric training was performed by the patients for 30 minutes once a day, 5 days a week, for 8 weeks using an Eccentron system. Surface electromyography was used to measure the lower extremity muscle activity, while a BioRescue was used to measure balancing ability. [Results] A significant difference in lower extremity muscle activation and balance ability was observed in group I compared with group II. [Conclusion] This study showed that virtual reality-based eccentric training using a slow velocity is effective for improving lower extremity muscle activity and balance in stroke patients.

RESUMO

[Purpose] The aims of this study were to determine (1) the significance of walking and foot pressure in stroke patients, and (2) the association between changes in postural alignment of stroke patients. [Subjects and Methods] Foot pressure and walking ability based on postural alignment were measured in 50 stroke patients. Trunk imbalance, trunk rotation, pelvic tilt, kyphosis, lordosis were measured using DIERS formetric4D (DIERS International GmbH, Schlangenbad, Germany), which anlalyzes 3-dimensional spinal structure in order to measure postural alignment. To determine foot pressure, the support rate of weight and, average foot pressure were measured using DIERS pedoscan (DIERS International GmbH, Schlangenbad, Germany) apparatus as a pressure platform. [Results] DIERS formetric 4D, DIERS pedoscan, and a 10 m walking test were utilized to measure foot pressure and walking ability relative to changes in postural alignment in participating stroke patients. [Conclusion] This study confirmed the significance of foot pressure and walking ability as related postural alignment, indicating that postural alignment education and a recovery therapy program for functional improvement of stroke patients should be provided together.

RESUMO

The soft tissue triangle is an easily recognizable subunit of the nose. Therefore, deformities in this region resulting from trauma or complications after cosmetic surgery can have serious cosmetic impacts. Various reconstruction choices exist for deformities such as depression of the soft triangle but choosing the most appropriate treatment in each case remains a challenge. In the case described herein, a patient underwent augmentation rhinoplasty with a silastic implant and experienced implant exposure in the soft triangle area. After implant removal, the patient complained of depression in this area. The authors effectively solved this problem through a de-epithelialized composite tissue graft. In this report, we present this case and review similar cases of reconstruction of the soft triangle.

RESUMO

BACKGROUND: Microfracture (MFx) is the most common procedure for treating chondral lesions in the knee; however, initial improvements decline after 2 years. Autologous matrix-induced chondrogenesis (AMIC) may overcome this shortcoming by combining MFx with collagen scaffolds. However, the outcomes of AMIC and MFx in the knee have not been compared. PURPOSE: To compare the clinical and radiological outcomes of AMIC and MFx over a minimum 2-year follow-up. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic search of the MEDLINE, Embase, and Cochrane Library databases identified studies of patients who underwent AMIC or MFx and that reported validated clinical outcome measure and/or radiological evaluation findings at a follow-up of ≥2 years. There were 2 reviewers who performed study selection, a risk of bias assessment, and data extraction. RESULTS: Overall, 29 studies were included in this systematic review. The mean improvement on the Lysholm score, Tegner activity scale, and visual analog scale for pain did not differ significantly between the 2 procedures. The mean improvement on the International Knee Documentation Committee (IKDC) subjective score was significantly greater in the AMIC (45.9 [95% CI, 36.2-55.5]) than in the MFx (27.2 [95% CI, 23.3-31.1]) group (P < .001). In addition, the mean magnetic resonance observation of cartilage repair tissue score was significantly higher in the AMIC (69.3 [95% CI, 55.1-83.5]) versus MFx (41.0 [95% CI, 27.3-54.7]) group (P = .005), and the mean adequate defect filling rate on magnetic resonance imaging scans was significantly better in the AMIC (77.3% [95% CI, 66.7%-87.9%]) versus MFx (47.9% [95% CI, 29.2%-66.6%]) group (P = .008) (odds ratio, 1.58 [95% CI, 1.07-2.33]). CONCLUSION: No significant differences in clinical outcomes, except for the IKDC subjective score, were found between the AMIC and MFx groups. Greater improvement in IKDC subjective scores and magnetic resonance imaging findings were seen in patients treated with AMIC compared with MFx at a minimum 2-year follow-up.

RESUMO

BACKGROUND: Given the superiority of meniscal repair over partial meniscectomy according to biomechanical data, the clinical outcomes of meniscal repair are likely to be better than those of partial meniscectomy for a medial meniscus root tear (MMRT). PURPOSE/HYPOTHESIS: This review was designed to compare the clinical and radiological results between meniscal repair and partial meniscectomy for MMRTs. It was hypothesized that meniscal repair would result in better clinical and radiological results compared with partial meniscectomy. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: Studies were included in the review if they (1) included patients with MMRTs who underwent primary arthroscopic meniscal repair or partial meniscectomy and (2) analyzed validated patient-reported outcomes and/or radiological evaluations. Summary odds ratios (ORs) with 95% CIs were calculated to compare partial meniscectomy with meniscal repair for each outcome. RESULTS: A total of 13 studies were included. The mean duration of follow-up was 33.5 and 47.2 months in the meniscal repair group and partial meniscectomy group, respectively. The change in the Lysholm score from preoperatively to postoperatively was statistically significantly in favor of meniscal repair (OR, 2.20 [95% CI, 1.55-3.12]), while no difference was found with respect to the change in the Tegner score between the 2 surgical approaches (OR, 1.21 [95% CI, 0.65-2.24]). The prevalence of postoperative severe knee osteoarthritis (OR, 0.31 [95% CI, 0.17-0.54]) as well as that of reoperations (OR, 0.05 [95% CI, 0.01-0.19]) were significantly in favor of meniscal repair. CONCLUSION: Better outcomes were seen after meniscal repair compared with partial meniscectomy for MMRTs, with greater improvements in Lysholm scores, and lower rates of progression to knee osteoarthritis, and lower reoperation rate.

RESUMO

BACKGROUND: Fingertip injuries are the most common type of traumatic injury treated at emergency departments and require prompt and adequate interventions for favorable wound survival outcomes. Hyperbaric oxygen (HBO2) therapy is well known for its many positive effects on wound healing. We hypothesized that treatment with HBO2 would improve the graft survival outcomes of amputated fingertip injuries treated with composite grafts. METHODS: This retrospective observational study included fingertip amputations that were treated between January 2013 and December 2017. A conventional group and an HBO2 therapy group were statistically compared to evaluate the effect of HBO2 treatment. Graft survival was categorized as either success or failure. RESULTS: Among 55 cases (digits), 34 digits were conventionally treated, while 21 digits were treated with HBO2. No statistically significant differences were observed between the groups with regard to general characteristics. Among patients with guillotine-type injuries, the composite graft success rate was statistically significantly higher in the group that received HBO2 therapy than in the conventional group (P=0.0337). Overall, the HBO2 group also demonstrated a statistically significantly shorter healing time than the conventional group (P=0.0075). As such, HBO2 treatment facilitates composite graft survival in cases of fingertip injury. CONCLUSIONS: HBO2 treatment was associated with an increased composite graft survival rate in guillotine-type fingertip injuries and reduced the time required for grafts to heal.

RESUMO

The surgical treatment of extensive urethral strictures remains a controversial topic; although techniques have evolved, there is still no definite method of choice. Since 1968, when Orandi presented an original technique for one-stage urethroplasty using a penile skin flap, the Orandi technique has become the most prevalently used one-stage procedure for anterior urethral strictures. We present a 20-year follow-up experience with one-stage reconstruction of long urethral strictures using a longitudinal ventral tubed flap of penile skin, with some important technical changes to Orandi's original technique to overcome the deficient vascularity caused by periurethral scar tissue. In 1997, a 55-year-old male patient complained of severe voiding difficulty and a weak urinary stream because of transurethral resection of the prostate due to benign prostatic hyperplasia. Another 47-year-old male patient had the same problem due to self-removal of a Foley catheter in 2002. In both patients, a urethrogram demonstrated extensive strictures involving the long segment of the anterior urethra. A rectangular skin flap on the ventral surface of the penis was used considering the appropriate length, diameter, and depth of the neourethra. The modified Orandi flap provided a pedicled strip of penile skin measuring an average of 8 cm. The mean duration of follow-up was 20.5 years. A long-term evaluation revealed stable performance characteristics without any complications.

RESUMO

BACKGROUND: Few studies to date have compared clinical outcomes in patients who have undergone medial patellofemoral ligament (MPFL) reconstruction using the suture anchor and double transpatellar tunnel fixation methods. This meta-analysis therefore compared the clinical results, including the patellar redislocation rate and improvement in functional scores, of suture anchor and double transpatellar tunnel fixation. HYPOTHESIS: The recurrence rate and improvement in functional outcomes after surgery would be similar using the suture anchor and double transpatellar tunnel fixation methods. STUDY DESIGN: Meta-analysis. METHODS: Studies evaluating MPFL reconstruction using either the suture anchor or double transpatellar tunnel technique for patellar site fixation were included if they reported the patellar redislocation rate after surgery and/or validated patient-reported outcomes such as the Kujala and Lysholm scores. RESULTS: Twenty-one studies were included in this meta-analysis. The mean patellar redislocation rates were similar using the suture anchor (3.2% [95% CI, 1.6%-6.2%]) and double transpatellar tunnel (3.4% [95% CI, 2.1%-5.4%]) techniques ( P = .879). The mean improvement in the Kujala score from before to after MPFL reconstruction was greater using the suture anchor (37.2 [95% CI, 31.1-43.4]) method than the double transpatellar tunnel method (28.7 [95% CI, 21.2-36.1]) ( P = .018). However, the mean improvement in the Lysholm score did not differ significantly using the 2 techniques. CONCLUSION: The patellar redislocation rate did not differ significantly in patients who underwent MPFL reconstruction using the suture anchor and double transpatellar tunnel fixation methods. The suture anchor fixation method, however, resulted in a greater degree of improvement in patient-reported outcomes.

RESUMO

BACKGROUND: Total knee arthroplasty (TKA) using an ultracongruent (UC) insert is widely performed. Lack of the posterior cruciate ligament or post-cam mechanism is a concern in terms of range of motion. The flexion angle of UC TKA had been well investigated; however, natural history and correlation factors of the postoperative extension angle have not been well documented. This study aimed to investigate time-dependent changes in extension after TKA using UC inserts, and to evaluate factors that correlated with the postoperative extension angle. METHODS: This study reviewed 388 gap-balanced UC TKAs (331 patients) without hyperextension at navigation and performed between November 2010 and December 2014. The extension angle (a positive number indicates hyperextension) was measured on full-extension lateral radiographs. The extension angles from five days post-operation to final follow-up were investigated. Factors correlated with the postoperative extension angle were evaluated using multiple regression analysis. RESULTS: Mean follow-up duration was 46.2 months. Until two years, the extension angle gradually increased; mean angles at five days/six months/one year/two years/and final follow-up were: -9.2°/-2.6°/0.6°/1.0°/1.0°, respectively. Female sex (ß = -0.15, P = 0.002) and pre-operative hyperextension (ß = 0.31, P < 0.001) were associated with postoperative hyperextension deformity. CONCLUSIONS: Following UC TKA, knees became gradually more extended until two years post-operation. Sex and pre-operative extension angle were predictive factors for the postoperative extension angle following UC TKA. LEVEL OF EVIDENCE: Level 4, Case series.

RESUMO

BACKGROUND: Types of mechanoreceptors may differ between the medial and lateral menisci, suggesting that postural stability may differ between patients with medial and lateral meniscus tears. However, to date, postural stability has not been compared in patients with medial and lateral meniscus tears. This study used stabilometry to compare postural stability in patients with medial and lateral meniscus tears. METHODS: Postural stability and thigh muscle strength were assessed in 24 patients with medial and 18 patients with lateral meniscus tears. Postural stability was determined by measuring the anteroposterior (APSI), mediolateral (MLSI), and overall (OSI) stability indices using stabilometry. Maximal torque (60°/s) of the quadriceps and hamstring was evaluated using an isokinetic testing device. RESULTS: The three stability indices, OSI, APSI, and MLSI, in both involved and uninvolved knees were all significantly greater in patients with lateral than with medial meniscus tears. (P<0.001 for all OSI, APSI, and MLSI in both involved and uninvolved knees, except for P=0.005 for MLSI of involved knees). In patients with medial meniscus tears, both OSI (1.4±0.4 vs. 1.1±0.4, P=0.037) and MLSI (0.9±0.3 vs. 0.8±0.3, P=0.041) were significantly higher on the injured than the uninjured side. In patients with lateral meniscus tears, none of the stability indices differed significantly between injured and uninjured knee joints. CONCLUSION: Postural stability of both the injured and uninjured knee joints was poorer in patients with lateral than with medial meniscus tears.
