RESUMO

Objective: To investigate the curative effects of bi-pedicled deep inferior epigastric perforator (DIEP) flap in repairing large soft tissue defects in the lower limbs. Methods: A retrospective observational study was conducted. From February 2016 to June 2020, 16 patients with large soft tissue defects in the lower limbs caused by trauma or after tumor/scar resection were admitted to the Department of Hand Surgery of the Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, including 9 males and 7 females, aged 25-58 years, with the area of soft tissue defects ranging from 14.0 cm×8.0 cm to 32.0 cm×18.0 cm. Using the abdomen as the donor site, the conjoined abdominal wall flap, i.e., the bi-pedicled DIEP flap (with an area ranging from 15.0 cm×9.0 cm to 32.0 cm×20.0 cm) carrying two sets of the trunk of the deep inferior epigastric artery was designed and resected to repair the wound. The donor site wound was sutured directly. The flap survival and wound healing in the donor and recipient areas were observed after operation. The curative effect was evaluated during the follow-up. At the last follow-up, the American Knee Society score and lower extremity functional scale were used to assess the functions of knee joint and lower limb, respectively. Results: The flaps of 15 patients survived after operation; the flap of one patient had partial infection at the edge after operation but healed after debridement and dressing change. The wounds in the donor and recipient areas of 16 patients all healed well. Follow-up of 16-28 months showed that the recipient area had a good shape and pliable texture, and there was no obvious swollen appearance, hyperpigmentation, or abnormal hair growth; the donor site had linear scar only, with no complications such as abdominal hernia or hyperplastic scar; the functions of knee joint and lower limb were well reconstructed, with no recurrence of tumor. At the last follow-up, among the 4 patients with knee joint injury, 3 cases were excellent and 1 case was good in the evaluation of knee joint function; among the 12 patients with lower limb injury, 9 cases were excellent and 3 cases were good in the evaluation of lower limb function. Conclusions: The donor site of bi-pedicled DIEP flap is concealed with abundant tissue and large area for resection, with which can be used to repair large soft tissue defects in the lower limbs, achieving good short-term results of appearance and function restoration.

RESUMO

Multiligamentous knee injuries (MLKI) are rare but devastating injuries that have a potential to cause long-term sequelae and significant morbidity. Frequently occurring concomitantly with knee dislocations (KD), MLKI have many risk factors that influence their incidence and treatment outcomes. Proper understanding of these risk factors can assist the surgeon with evaluation, surgical planning, and managing patient expectations both pre- and postoperatively. The purpose of this review is fourfold: (1) identify the risk factors and injuries associated with MLKI, (2) describe factors implicated in the treatment of MLKI, (3) report the effect of these risk factors on outcomes of MLKI, and (4) provide a brief insight into MLKI at our tertiary referral academic care center. This was a retrospective review of literature relevant to MLKI. Studies that described injuries, risk factors, treatment techniques, or outcomes associated with MLKI were included in our review. A total of 35 studies (consisting of level 3 and 4 evidence) published between 2009 and 2020 were found and included in our analysis. In addition, 25 patients who underwent treatment for MLKI at the University of Chicago Medical Center between December 2015 and December 2019 were included in our analysis. MLKI tend to occur in the younger male population. Increasing age, body mass index, and severity of the injury have been correlated with worse functional and patient-reported outcomes. Operative treatment is indicated for MLKI; however, timing and repair versus reconstruction is still debated, and is often decided on a patient by patient basis. Retrospective cohort studies have indicated that reconstruction may be favored; however, further more rigorous studies are needed to better characterize this finding. MLKIs are devastating injuries with significant variability in presentation, treatment, and outcome. Variations in these are largely attributable to the mechanism and severity of injury, timing, and surgeon preference. A holistic approach, and understanding of the present literature, is required to best optimize patient outcome.

RESUMO

CONTEXT: Postoperative quadriceps strength weakness after knee surgery is a persistent issue patients and health care providers encounter. OBJECTIVE: To investigate the effect of neuromuscular electrical stimulation (NMES) parameters on quadriceps strength after knee surgery. DATA SOURCES: CINAHL, MEDLINE, SPORTDiscus, and PubMed were systematically searched in December 2018. STUDY SELECTION: Studies were excluded if they did not assess quadriceps strength or if they failed to report the NMES parameters or quadriceps strength values. Additionally, studies that applied NMES to numerous muscle groups or simultaneously with other modalities/treatments were excluded. Study quality was assessed with the Physiotherapy Evidence Database (PEDro) scale for randomized controlled trials. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 1. DATA EXTRACTION: Treatment parameters for each NMES treatment was extracted for comparison. Quadriceps strength means and standard deviations were extracted and utilized to calculate Hedge g effect sizes with 95% CIs. RESULTS: Eight RCTs were included with an average Physiotherapy Evidence Database scale score of 5 ± 2. Hedge g effect sizes ranged from small (-0.37; 95% CI, -1.00 to 0.25) to large (1.13; 95% CI, 0.49 to 1.77). Based on the Strength of Recommendation Taxonomy Quality of Evidence table, the majority of the studies included were low quality RCTs categorized as level 2: limited quality patient-oriented evidence. CONCLUSION: Because of inconsistent evidence among studies, grade B evidence exists to support the use of NMES to aid in the recovery of quadriceps strength after knee surgery. Based on the parameters utilized by studies demonstrating optimal treatment effects, it is recommended to implement NMES treatment during the first 2 postoperative weeks at a frequency of ≥50 Hz, at maximum tolerable intensity, with a biphasic current, with large electrodes and a duty cycle ratio of 1:2 to 1:3 (2- to 3-second ramp).

RESUMO

PURPOSE: To determine the clinical and radiographic efficacy of chitosan-glycerol phosphate/blood implant versus hyaluronic acid-based cell-free scaffold in patients with focal osteochondral lesion of the knee joint. METHODS: Clinical data of 46 patients surgically treated using either chitosan-glycerol phosphate/blood implant (25 patients, Group 1) or hyaluronic acid-based cell-free scaffold (21 patients, Group 2) in combination with microfracture were retrospectively evaluated. All lesions were Outerbridge grade III or IV with a mean lesion size of 3.3 ± 0.7 cm2. The mean follow-up time was 24.4 months. Visual analogue scale (VAS), Lysholm knee score, and Tegner activity scale were the instruments to evaluate the clinical status. Magnetic resonance observation of cartilage repair tissue (MOCART) system was used to analyze the characteristics of repair tissue. RESULTS: No significant differences were detected between the groups regarding VAS, Lysholm, and Tegner scores at any time interval during the whole follow-up. The mean post-operative VAS and Lysholm scores at the latest follow-up was significantly better in cases with the lesion size ≤ 3 cm2 in Group 1 (p = 0.001, p < 0.001, respectively). However, no significant differences according to the lesion size were detected in Group 2 (n.s.). Complete repair with the filling of the defect was achieved in 7 (28%) of the knees in Group 1 and it was 7 (33.3%) of the knees in Group 2 according to MOCART system at the latest follow-up. CONCLUSION: Single-stage regenerative cartilage surgery using chitosan-glycerol phosphate/blood implant combined to microfracture for focal osteochondral lesions of the knee revealed similar clinical and radiographic outcomes with hyaluronic acid-based cell-free scaffold at short-term follow-up. However, clinical outcomes of hyaluronan scaffold were less sensitive to defect size than chitosan. With the advantages of no hypertrophic repair tissue formation as well as no need to arthrotomy during surgery, chitosan is an effective choice especially in patients with the lesion size ≤ 3 cm2. LEVEL OF EVIDENCE: III.

RESUMO

PURPOSE: Knee ligamentous trauma and the following pain is one of the most prevalent athletic injuries. Transcutaneous electrical nerve stimulation is one of the conservative approaches in controlling pain which is low cost, noninvasive, and safe with low complications. Our purpose was to study whether transcutaneous electrical nerve stimulation (TENS) could help athletes perform better during the first phase of rehabilitation (0-4 weeks) after anterior cruciate ligament (ACL) reconstruction surgery and until the follow-up. METHODS: This randomized single blind (exercise instructor and assessor) clinical trial was performed on 70 male athletes, undergone ACL surgery. After the surgery, patients were randomly divided into two groups: the first group received semi-supervised exercise plus high-frequency TENSTENS for 35 min a day and the second group only performed exercises. Treatment duration continued for 20 sessions, 4 weeks. The visual analog scale (VAS) score (100 mm), International Knee Documentation Committee (IKDC) questionnaire and knee flexion Range of motion (ROM) were evaluated for all patients after the surgery (before commencing the rehabilitation program), after 4 weeks and 14 weeks from the surgery. RESULTS: Mixed ANOVA was used to explore the interaction effects of time and group on outcome measures and post hoc additional tests were performed on the data. The VAS, IKDC questionnaire score and knee flexion ROM increased in both groups over time, but the amount of improvement did not differ between the two groups, implying no additional improvement in the group receiving TENS along with exercises. CONCLUSION: The findings of the present trial shows that adding TENS to a specific protocol of semi-supervised exercise in the first phase of rehabilitation after ACL reconstruction is not efficient on improving knee function and pain more than exercise alone. Implications for Rehabilitation Injury to the anterior cruciate ligament of the knee is a common injury specifically in athletes. Incorporating effective pain relieving strategies during the post anterior cruciate ligament reconstruction surgery rehabilitation could lead to improvement in regaining the range of motion and function of the knee which is of crucial importance after the surgery. Applying transcutaneous electrical nerve stimulation alongside a specific protocol of semi-supervised exercise in the first phase of rehabilitation after anterior cruciate ligament reconstruction did not have any additional effect to exercise alone.

RESUMO

PURPOSE: The purpose of the present study was to evaluate the effects of pulsed electromagnetic fields (PEMFs) on clinical outcome in patients who underwent arthroscopic matrix-assisted autologous chondrocyte implantation (MACI) for chondral lesions of the knee. METHODS: Thirty patients affected by grade III and IV International Cartilage Repair Society chondral lesions of the knee underwent MACI. After surgery, patients were randomly assigned to either experimental group (PEMFs 4 h per day for 60 days) or control group . Clinical outcome was evaluated through International Knee Documentation Committee (IKDC) subjective knee evaluation form, Visual Analog Scale, Short Form-36 (SF-36) and EuroQoL before surgery and 1, 2, 6, and 60 months postoperative. RESULTS: Mean size of chondral lesion was 2.4 ± 0.6 cm2 in the PEMFs group and 2.5 ± 0.5 cm2 in the control one. No differences were found between groups at baseline. IKDC score increased in both groups till 6 months, but afterward improvement was observed only in the experimental group with a significant difference between groups at 60 months (p = 0.001). A significant difference between groups was recorded at 60 months for SF-36 (p = 0.006) and EuroQol (p = 0.020). A significant pain reduction was observed in the experimental group at 1-, 2- and 60-month follow-up. CONCLUSION: Biophysical stimulation with PEMFs improves clinical outcome after arthroscopic MACI for chondral lesions of the knee in the short- and long-term follow-up. Biophysical stimulation should be considered as an effective tool in order to ameliorate clinical results of regenerative medicine. The use of PEMFs represents an innovative therapeutic approach for the survival of cartilage-engineered constructs and consequently the success of orthopaedic surgery. LEVEL OF EVIDENCE: II.

RESUMO

BACKGROUND: A goal of anterior cruciate ligament (ACL) reconstruction is to provide a meniscal protective effect for the knee. PURPOSE: (1) To evaluate whether there was a different likelihood of subsequent meniscal surgery in the ACL-reconstructed knee or in the normal contralateral knee and (2) to compare the risk factors associated with subsequent meniscal surgery in the ACL-reconstructed knee and contralateral knee. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Using an integrated health care system's ACL reconstruction registry, patients undergoing primary ACL reconstruction, with no meniscal injury at the time of index surgery and a normal contralateral knee, were evaluated. Subsequent meniscal tears associated with ACL graft revision were excluded. Subsequent meniscal surgery in either knee was the outcome of interest. Sex, age, and graft type were assessed as potential risk factors. Survival analysis was used to compare meniscal surgery-free survival rates and to assess risk factors of subsequent meniscal surgery. RESULTS: Of 4087 patients, there were 32 (0.78%) patients who underwent subsequent meniscal surgery in the index knee and 9 (0.22%) in the contralateral knee. The meniscal surgery-free survival rate at 4 years was 99.08% (95% CI, 98.64%-99.37%) in the index knee and 99.65% (95% CI, 99.31%-99.82%) in the contralateral knee. There was a 3.73 (95% CI, 1.73-8.04; P < .001) higher risk of subsequent meniscal surgery in the index knee compared with the contralateral knee, or a 0.57% absolute risk difference. After adjustments, allografts (hazard ratio [HR], 5.06; 95% CI, 1.80-14.23; P = .002) and hamstring autografts (HR, 3.11; 95% CI, 1.06-9.10; P = .038) were risk factors for subsequent meniscal surgery in the index knee compared with bone-patellar tendon-bone (BPTB) autografts. CONCLUSION: After ACL reconstruction, the overall risk of subsequent meniscal surgery was low. However, the relative risk of subsequent meniscal surgery in the ACL-reconstructed knee was higher compared with the contralateral knee. Only graft type was found to be a risk factor for subsequent meniscal surgery in the ACL-reconstructed knee, with a higher risk for allografts and hamstring autografts compared with BPTB autografts.

RESUMO

INTRODUCTION: Multimodal pain management is used after total knee arthroplasty (TKA) to reduce opioid intake. Transcutaneous electrical nerve stimulation (TENS) has generated much interest as a non-pharmacologic, patient-controlled therapy. The aims of this study were to evaluate the efficacy of TENS in reducing opioid intake and improving recovery after TKA. MATERIALS AND METHODS: This was a prospective, parallel-group, double-blinded, randomized trial of patients receiving femoral nerve catheter block with allocation to either active or placebo TENS device groups. All participants were 18-85 years and underwent unilateral, primary TKA at two academic hospitals. Device usage was monitored during inpatient and outpatient phases. Participants were requested to return at second, fourth, and sixth postoperative weeks for follow-up. The primary endpoint was opioid usage, as indicated by medication intake in equianalgesic equivalents to morphine. Secondary measures included: visual analogue scale (VAS) pain scores; functional assessments as measured from knee joint range of motion (ROM) and Timed Up and Go (TUG) test; and clinical outcomes as defined by modified Knee injury and Osteoarthritis Outcome Scores (KOOS) and the 12-item Short Form Survey Instrument (SF-12). RESULTS: Among 116 participants, overall withdrawal was 37.9% (44 patients) at similar rates in both study arms. After excluding for non-femoral nerve catheter (FNC) blocks (i.e., protocol deviations), there were 35 patients in the active group and 31 patients in the placebo group whose complete records were analyzed. There were no significant differences between groups in any of the clinical endpoints.

RESUMO

PURPOSE: To determine the association between the use of preoperative antibiotics and the risk of postoperative infection after simple knee arthroscopy. METHODS: The electronic medical records of a large integrated health care organization were used to identify patients who underwent simple knee arthroscopy between 2007 and 2012. Patient demographics, potential infection risk factors, and antibiotic administration data were extracted. Simple knee arthroscopy included debridement, meniscectomy, meniscus repair, synovectomy, microfracture, and lateral release. Complex knee arthroscopy, septic knees, and cases involving fractures were excluded. Deep infection was defined as a positive synovial fluid culture or signs and symptoms of infection and gross pus in the knee. Superficial infection was defined as clinical signs of infection localized to a portal site and treatment with an antibiotic. RESULTS: Of 40,810 simple knee arthroscopies, 32,836 (80.5%) received preoperative antibiotics and 7,974 (19.5%) did not. There were 25 deep infections in the antibiotic group (0.08%) and 11 in the no-antibiotics group (0.14%) (risk ratio = 0.55, 95% confidence interval: 0.27 to 1.12, P = .10). There were 134 superficial infections in the antibiotic group (0.41%) and 32 in the no-antibiotics group (0.40%) (risk ratio = 1.01, 95% confidence interval: 0.29 to 1.49, P = .93). CONCLUSIONS: In our large sample of patients who underwent simple knee arthroscopy, there was no association between preoperative antibiotic use and postoperative deep or superficial infection rates at the 95% confidence level (P = .05). There was an association between preoperative antibiotic use and a decreased deep infection rate at the P = .10 level. LEVEL OF EVIDENCE: Level IV, case series.

RESUMO

BACKGROUND: Stiffness is common following fractures around knee. Manipulation under anesthesia (MUA) is the initial noninvasive procedure usually performed for such patients. Though MUA has been extensively evaluated for knee arthroplasty, there is paucity of literature regarding its benefits in trauma cases. The purpose of this study was to define the role of manipulation in post traumatic stiff knees. METHODS: Hospital inpatient and outpatient records from January 2010 to June 2014 were retrospectively reviewed to identify patients undergoing MUA at our institution. Patients with more than one year follow up and adequate data were included. Clinical and radiographic parameters were analyzed to assess outcomes, complications, effect of timing on flexion gain as well as identify risk factors associated with failure. RESULTS: Out of 45 patients undergoing manipulation, 41 patients with 48 knees (34 unilateral and 7 bilateral) met inclusion criteria. Thirty six manipulations were successful while 3 were abandoned due to tight tissues and 9 developed complications.Successful MUA resulted in immediate gain of 62.36° of flexion which decreased to 49.86° at 1year. There was statistically significant loss of flexion of 12.5° over a year (p value 0.0013). Arc of motion improved from 48.5° to 106.1° at 1year (p value <0.0001). Significant improvement was also seen in extension and fixed flexion deformity (p value <0.0001). No significant difference could be detected between early (<3 months) and late (>3 months) groups with respect to outcomes (p value 0.883)or complications (p value 0.3193). Failed group had significantly lower pre MUA flexion and pre MUA range of motion (p value 0.003). Univariate analysis showed that extensor mechanism ruptures during injury (p value <0.0001) and knees with Flexion <40° (p value 0.0022) or ROM<30° (p value 0.0002) were significantly associated with failures. CONCLUSION: MUA is a suitable non invasive treatment option for post traumatic stiffness. There is no effect of timing on outcome and late manipulation also results in good outcome. Extensor mechanism rupture and pre manipulation ROM<30° or flexion <40° are associated with failure and such cases should be considered for alternative options for better outcome.

RESUMO

OBJECTIVE: To study clinical outcomes of Chinese medidine fumigation and massage therapy for the treatment of knee stability and functional recovery after anterior cruciate ligament reconstruction operation,and to explore the effect on tendon-bone healing. METHODS: Total 50 patients were divided into two groups: the control group (normal rehabilitation therapy group),the treatment group (Chinese medicine fumigation and manipulation group). There were 25 patients in the control group, including 16 males and 9 females, who were treated with isometric muscle training, with the gradually enlarging amplitude of flexion and progressive loading of bearing training for knee recovery. There were 25 patients in the treatment group, including 15 males and 10 females,who were treated with the conventional rehabilitation therapy combined with Chinese medicine fumigation and massage therapy. The Chinese herbs named as Haitongpi decoction was steamed by a special equipment to fumigate the knee after operation; Based on the biomechanical parameters of the ligament reconstruction, the massage therapy was designed to control the degree of the knee flexion and release the adhesion for early recovery of knee functions. The Lysholm knee function evaluation system was used, and MRI examination was performed to measure the change in width of ligament tunnel in femur and tibia to evaluate the safety and stability of the treatment. RESULTS: Lysholm system showed that two groups both had improving results from the 1st month after operation to the 3rd month (treatment group, F=36.54, P<0.05; the control group, F=28.12, P<0.05), and the results of the treatment group was better than that of the control group at the observation point (the 1st month, t=0.105, P<0.05; the 3rd month, t=5.361, P<0.01). There was no difference between the two groups when evaluating the bone and tendon healing 3 and 12 months after operation (P>0.05), indicating that Chinese rehabilitation therapy was a safety treatment without the influence on the loosing of tendon. CONCLUSION: Chinese medicine fumigation and massage therapy can early improve the knee function after the anterior cruciate ligament reconstruction operation without the disturbance of the knee stability.

RESUMO

PURPOSE: Partial patellectomy (PP) and reattachment of the patellar ligament with transosseous suturing is the mainstay of surgical treatment for distal pole patellar fractures. An anchor suturing (AS) technique has recently been reported as an alternative to PP in such fractures and allows for bone-to-bone interface and possibly superior fracture healing than bone-to-tendon interface with PP. We present our experience with AS and compare it to PP. METHODS: Between 2006 and 2011, 60 patients with distal pole patellar fracture underwent either AS (n = 27) or PP (n = 33). We retrospectively gathered their demographic data and information on fracture type, fixation technique, operation time, postoperative complications and knee range of motion. A telephone survey was performed to grade functional outcomes with standard questionnaires (the SF-12 for quality of life, the Kujala score for patellofemoral function and a visual analog scale [VAS] pain score). RESULTS: AS was equivalent to PP in terms of residual pain and functional outcomes (VAS: 2.45 vs. 2.26, p = 0.83 and Kujala score: 74.3 vs. 69, p = 0.351, respectively) as well as for knee range of motion. Complications included three cases of infection in each group, two cases of early hardware failure and one case of non-union in the AS group. Operation time was significantly shorter for AS compared to PP (68.5 vs. 79.1 min, p = 0.03). CONCLUSIONS: AS is non-inferior to PP for function and pain after distal pole patellar fractures and is superior to PP with regard to operative time.

RESUMO

PURPOSE: Pulsed electromagnetic fields (PEMFs) may improve clinical outcomes following microfractures and prevent their decline over time. METHODS: Sixty-eight patients who underwent partial medial meniscectomy and microfractures to the medial femoral condyle for management of grade III-IV cartilage lesions were randomly divided into two groups using a block randomization procedure. After surgery, 34 patients underwent PEMFs application in the I-ONE group; 34 patients underwent placebo treatment in the placebo group. All patients had the same postoperative rehabilitation protocol. Sixty patients (28 in the I-ONE group, 32 in the placebo group) were assessed at an intermediate follow-up of two years and a minimum follow-up of five years after surgery. RESULTS: The two groups were homogeneous. There was a significant improvement from baseline to the last minimum follow up of two years. At two years, IKDC and Lysholm and Constant scores were significantly improved compared to baseline in both groups with no significant inter-group differences. At the last follow up (minimum five years), clinical and functional outcomes were decreased in both the groups, with significant better outcomes in the I-ONE group. At five years, the percentage of patients still active at the same level they were pre-operatively was greater in the I-ONE group (82% vs 68%, P = 0.28). At radiographic assessment, at the latest evaluation, six patients (21.4%) in the I-ONE group and nine (28.1%) in the placebo group demonstrated grade I-II degenerative changes according to Fairbank grading system (Χ = 0.36, P = 0.55). CONCLUSIONS: PEMFs application can improve the effectiveness of microfracture in the long term.

RESUMO

Muscle strength is a determinate of physical function and increasing muscle strength is an important clinical goal for patients with knee injury. This article discusses the emerging evidence regarding a novel rehabilitation strategy that uses disinhibitory modalities to increase neuromuscular activation in conjunction with traditional muscle strengthening for the purpose of maximizing strength gains following acute knee injury or surgery and in patients with knee osteoarthritis. The use of disinhibitory modalities and specific types of neuromuscular training for clinically maximizing strength are discussed.

RESUMO

BACKGROUND: Neuromuscular electrical stimulation (NMES) has been shown to reduce quadriceps activation failure (QAF), and eccentric exercise has been shown to lessen muscle atrophy post-ACL reconstruction. Given that these are two critical components of quadriceps strength, intervention combining these therapies may be effective at reinstituting quadriceps function post-reconstruction. Thus, the aim of this study was to evaluate the effectiveness of a combined NMES and eccentric exercise intervention to improve the recovery of quadriceps activation and strength post-reconstruction. METHODS: Thirty-six individuals post-injury were placed into four treatment groups (N&E, NMES and eccentrics; E-only, eccentrics only; N-only, NMES-only; and STND, standard of care) and ten healthy controls participated. N&E and N-only received the NMES protocol 2× per week for the first 6 weeks post-reconstruction. N&E and E-only received the eccentric exercise protocol 2× per week beginning 6 weeks post-reconstruction. Quadriceps activation was assessed via the superimposed burst technique and quantified via the central activation ratio. Quadriceps strength was assessed via maximal voluntary isomeric contractions (Nm/kg). Data was gathered on three occasions: pre-operative, 12-weeks-post-surgery and at return-to-play. RESULTS: No differences in pre-operative measures existed (P>0.05). E-only recovered quadriceps activation better than N-only or STND (P<0.05). N&E and E-only recovered strength better than N-only or the STND (P<0.05) and had strength values that were similar to healthy at return-to-play (P>0.05). CONCLUSION: Eccentric exercise was capable of restoring levels of quadriceps activation and strength that were similar to those of healthy adults and better than NMES alone. LEVEL OF EVIDENCE: Level 3, Parallel longitudinal study.

RESUMO

Although glucosamine is commonly consumed by athletes, its effectiveness in sports injuries is still under debate. We aimed to investigate the effects of glucosamine to the rehabilitation outcomes of anterior cruciate ligament (ACL) reconstructed athletes. Glucosamine-sulfate (1000 mg daily, for 8 weeks) was administered to half of the cohort of 30 male athletes, the other half used a placebo. Both groups received the same rehabilitation protocol. Knee pain and functions were evaluated by a visual analogue scale (VAS), International Knee Documentation Committee (IKDC) and Lysholm scores before and after oral administration. Additionally, an isokinetic test was performed after the administration period. The scores revealed significant improvements in both groups after 8 weeks, but no significant difference was detected between groups in any of the parameters. Glucosamine supplementation did not improve the rehabilitation outcomes of athletes after ACL reconstruction. This is the first study investigating this topic. Further studies will help to obtain clear evidence about glucosamine efficacy on ACL injured or ACL reconstructed athletes.

RESUMO

OBJECTIVE: To evaluate the clinical outcome of arthroscopic repair method of meniscus injury with Fast-fix under local anesthesia. METHODS: From October 2005 to September 2012,106 patients with meniscus injuries admitted into our - hospital were studied, including 74 males and 32 females, ranging in age from 13 to 71 years old, averaged 27.6 years old. The duration of the disease ranged from 15 days to 5 years. The main clinical manifestations included knee joint pain after exercise, joint locking, pressing pain of knee joint and positive McMurray signs. The MRI showed meniscus tear or degeneration. Arthroscopic repairing surgeries were performed with Fast-fix under local anesthesia. Each patient was assessed with VAS pain evaluation and Lysholm knee-joint score system before and after operation. All the patients were followed up more than 1 year. RESULTS: One hundred and 2 patients were followed up by recording subjective symptoms, clinical examinations and questions naires for an average of 2.6 years (ranged, 1.1 to 8 years), and 4 patients lost follow-up. All the 102 patients had no anesthetic complications. Ninety-six patients had normal subjective symptom and clinical examinations. Four patients had a mild ache with activities,2 patients had moderate pain after activities with joint space pressing pain. VAS pain evaluation and Lysholm knee-joint score after operation both were much better than that before operation. CONCLUSION: onclusion: Local anesthesia can provide nice circumstances for surgeries. Arthroscopic repair using Fast-fix is an idea method for meniscus injury, especially for the posterior horn tear of medial meniscus, which is simple and convenient with less complications, and satisfactory results.

RESUMO

Objetivo: Evaluar la efectividad de las infiltraciones postquirúrgicas de anestésico local solo y combinado con corticoide, para el tratamiento del dolor e inflamación en el postoperatorio temprano en pacientes intervenidos de menisco artroscópicamente. Material y método: Estudio clínico prospectivo randomizado de 60 pacientes a los que se les practicó menisectomía artroscópica. Finalizada la intervención, los pacientes fueron asignados aleatoriamente a uno de los dos grupos de estudio y se infiltró en un grupo 10 ml de clorhidrato de bupivacaína al 0,5% y en el otro el mismo anestésico, asociado a triamcinolona acetónido (solución de 40 mg). La percepción del dolor fue medida objetivamente por la Escala Visual Análoga (EVA), registrándose el dolor postquirúrgico a las 2, 4 y 24 horas y a los 15 días y al mes, después de la intervención. Resultados: No se encontraron diferencias significativas entre los diferentes grupos de estudio. Conclusión: La infiltración anestésica postquirúrgica en dosis única es un procedimiento muy útil para el manejo del dolor postoperatorio en pacientes que requieren la realización de una menisectomía artroscópica (AU)

RESUMO

There is no consensus in the postoperative rehabilitation regimen for patients who have undergone surgery for medial meniscus damage. The aim of this study was to examine whether it is necessary to undergo postoperative physiotherapy treatment these patients. A prospective randomized controlled clinical trial was performed. 42 participants (26 males, 16 women) were randomly assigned into an exercise group (EG) (n = 22) or a control group (CG) (n = 20). Prognostic variables were similar between the groups at baseline. The EG achieved significantly better outcome effects than the CG at pain (VAS reduced 1.9 in TG and 0.6 in CG, p < 0.01) and function (KOOS decreased 18.0 in TG and only 6.5 in CG, p < 0.01) during the 12 week intervention period. The results after a 12-month follow-up indicated the same results as at posttest 3 months postoperatively. In patients with surgery for degenerative meniscus damage, postoperative medical exercise therapy - as a model of physiotherapy - is an efficient treatment alternative compared to no systematic rehabilitation.

RESUMO

PURPOSE: To evaluate the hypothetical toxic effect of local anesthetics on the articular cartilage using patient data from autologous chondrocyte cultivation with different anesthesia types used for arthroscopic cartilage biopsy specimen procurement. METHODS: A retrospective analysis of patient data from the national autologous chondrocyte implantation registry and the corresponding hospital records was approved by the National Medical Ethics Committee. Articular cartilage biopsy specimens from the knees of 49 consecutive patients assigned for autologous chondrocyte implantation (aged 14 to 44 years) were procured from the non-weight-bearing articular surface during arthroscopy under general anesthesia (12 patients), spinal anesthesia (18 patients), or local anesthesia (intra-articular injection of 15 to 20 mL of 2% lidocaine hydrochloride) (19 patients). All the biopsy specimens were further manipulated following the same chondrocyte cultivation protocol. General patient data and surgery-related parameters, together with chondrocyte viability, population doublings, and chondrocyte morphology in biopsy specimens and primary cell cultures, were analyzed and compared across different types of anesthesia. RESULTS: Patients in the general, spinal, and local anesthesia groups showed no statistical differences in age (27 years, 29 years, and 32 years, respectively), duration of surgery (36 minutes, 37 minutes, and 39 minutes, respectively), weight of biopsy specimens (110 mg, 178 mg, and 130 mg, respectively), cell viability in cartilage biopsy specimens (67%, 69%, and 78%, respectively) or primary cultures (95%, 95%, and 95%, respectively), and population doublings (5.2, 5.2, and 5.2, respectively). Similar chondrocyte morphology in primary cell cultures was observed among the 3 groups. CONCLUSIONS: This retrospective study showed that a single intra-articular injection of lidocaine hydrochloride used for knee arthroscopy did not influence the viability, morphology, and cultivation potential of chondrocytes in articular cartilage biopsy specimens assigned for autologous chondrocyte implantation. LEVEL OF EVIDENCE: Level IV, retrospective comparative study.
