Almost 79% survival rate at 10-year follow-up for the patellofemoral joint arthroplasty: An Italian prosthetic registry study.

PURPOSE: The aims of the present study were (1) to evaluate the survival of patellofemoral joint (PFJ) arthroplasty in a large cohort of patients using data obtained from an Italian regional arthroplasty registry and (2) to collect clinical outcomes of a subgroup of patients, with a minimum follow-up of 4 years. The hypotheses were that PFJ arthroplasty is a procedure that had good survival and clinical outcomes, not inferior to those reported in the literature for primary total knee arthroplasty (TKA). METHODS: The Register of Orthopaedic Prosthetic Implants (RIPO) of Emilia-Romagna (ER) (Italy) database was searched for the inclusion of all PFJ arthroplasties implanted between 2003 and 2019. PFJ arthroplasties were excluded if they were implanted in patients who lived outside of the ER. The survival information was extrapolated from the RIPO considering the partial or total revision of the implant as failure; moreover, a subgroup of patients was contacted and interviewed by telephone to collect clinical outcomes. Descriptive statistics were used to summarise the data. The survival curve was calculated and plotted using the Kaplan-Meier method. RESULTS: A total of 126 arthroplasties in 114 patients were included in the final analysis (mean age at surgery 60.1 ± 11.5 years old). The main causes of patellofemoral arthroplasty were primary osteoarthritis (88%) and posttraumatic arthritis (7%). The survival was 90.4 ± 30.6 and 78.8 ± 51.5 at 5 and 10 years of follow-up, respectively. At the latest follow-up, 23 implants failed (18.3%). The main cause of revision was osteoarthrosis progression (34.8%). A total of 44 patients were contacted by telephone to collect clinical outcomes: Western Ontario and McMaster Universities Osteoarthritis Index, functional Knee Society Score, Forgotten Joint Score and Oxford Knee Score. These patients reported good to excellent scores at a medium follow-up of 10.3 ± 4.7 years. CONCLUSIONS: The PFJ showed good survival and clinical outcomes and could be considered a valuable option for patients affected by isolated patellofemoral osteoarthritis. LEVEL OF EVIDENCE: Level IV.

Silver-Coated Distal Femur Megaprosthesis in Chronic Infections with Severe Bone Loss: A Multicentre Case Series.

Periprosthetic joint infections (PJI) and fracture-related infections (FRI) of the distal femur (DF) may result in massive bone defects. Treatment options include articulated silver-coated (SC) megaprosthesis (MP) in the context of a two-stage protocol. However, there is limited evidence in the literature on this topic. A retrospective review of the prospectively maintained databases of three Institutions was performed. Forty-five patients were included. The mean follow-up time was 43 ± 17.1 months. Eight (17.8%) patients had a recurrent infection. The estimated recurrence-free survival rate was 91.1% (93.5% PJI vs. 85.7% FRI) 2 years following MP implantation, and 75.7% (83.2% PJI vs. 64.3% FRI; p = 0.253) after 5 years. No statistically relevant difference was found according to the initial diagnosis (PJI vs. FRI). Among possible risk factors, only resection length was found to significantly worsen the outcomes in terms of infection control (p = 0.031). A total of eight complications not related to infection were found after reimplantation, but only five of them required further surgery. Above-the-knee amputation was performed in two cases (4.4%), both for reinfection. Articulated DF SC MP in a two-stage protocol is a safe and effective treatment for chronic knee infection with severe bone loss.

Satisfactory long-term outcomes for combined anterior cruciate ligament reconstruction and lateral closing wedge high tibial osteotomy.

PURPOSE: A combined anterior cruciate ligament (ACL) reconstruction and high tibial osteotomy (HTO) is considered a valuable treatment in young patients affected by symptomatic medial osteoarthritis and ACL deficiency. However, only a few studies have investigated the outcomes of this procedure, especially in the long term. Therefore, the aim of this study is to report clinical and radiographic outcomes of ACL reconstruction and lateral closing wedge HTO at a mean of 14 years of follow-up. METHODS: Patients were prospectively evaluated pre-operatively, after 6.5 ± 2.7 years and 14.3 ± 2.2 years. Patient-reported outcome measures (PROMs) were collected, knee laxity was assessed through KT-1000 arthrometer, and limb alignment and knee osteoarthritis were evaluated on long-cassette radiographs. Survivorship of the surgical procedure was calculated through the Kaplan-Meier method. RESULTS: 32 patients were initially enrolled and completed the mid-term evaluation (6.5 ± 2.7 years), and 23 patients (72%) were available for the final evaluation at 14.3 ± 2.2 years after surgery. Statistically significant improvement was found for all the clinical scores (VAS, WOMAC, Tegner, subjective IKDC, objective IKDC) between the pre-operative status and the mid-term follow-up (p < .001). VAS, subjective IKDC and objective IKDC showed no statistically significant differences (p > .05) between the mid-term and the final follow-up; a significant decrease of WOMAC (p < .05) and Tegner (p < .001) was found from mid-term to final follow-up. Significant progression of osteoarthritis was found for all the knee compartments. The survivorship was 95.7% at 5 years, 82.6% at 10 years, and 72.8% at 15 years. CONCLUSIONS: Combined ACL reconstruction and lateral closing wedge HTO showed satisfactory clinical outcomes and survivorship at a mean of 14 years follow-up. LEVEL OF EVIDENCE: IV.

Piezoelectric ultrasonic debridement as new tool for biofilm removal from orthopedic implants: A study in vitro.

Pulse lavage (PL) debridement is the standard treatment used in Debridement, Antibiotics and Implant Retention (DAIR) for bacterial biofilm removal during acute and early postoperative cases of periprosthetic joint infection (PJI). The failure rate of DAIR is still high due to the inadequacy of PL in removing the biofilm. Ultrasound-based techniques are a well-established tool for PJI diagnosis due to their ability to completely eradicate the biofilm from implant surfaces. Hence, this study investigates the efficiency of a piezoelectric ultrasonic scalpel (PUS) in removing bacterial biofilm from different orthopedic implant materials in vitro and compares the results with PL. Biofilms of methicillin-resistant Staphylococcus aureus strains were grown on titanium alloy (Ti6Al4V ELI), stainless steel (AISI 316L), and ultrahigh molecular weight polyethylene (UHMWPE) disks for 24 h. The disks of each material were divided into three groups: (i) a control group (no lavage/debridement), (ii) a group treated with PL, (iii) a group treated with PUS. The disks were then sonicated for viable cell count to measure the residual biofilm content. Compared to the initial cell count (105 CFU/mL for each material), PL showed a two-log reduction of CFU/mL (p < 0.001 for each material), while for PUS a four-log reduction was found (p < 0.001 for each material). The comparison between the two lavage/debridement displayed a two-log reduction of CFU/mL (p < 0.001 for each material) of PUS compared with PL. Its increased efficiency compared with PL promotes the use of PUS in removing bacterial biofilm from orthopedic implants, suggesting its implementation to improve the success rate of DAIR.

The 25-year experience of over-the-top ACL reconstruction plus extra-articular lateral tenodesis with hamstring tendon grafts: the story so far.

This article presents with an evidence based approach, the kinematical rationale, biological evidence and the long term results of the "Over-The-Top" anterior cruciate ligament reconstruction with lateral plasty technique. This surgery was developed more than 25 years ago at the Rizzoli Institute by professor Marcacci and Zaffagnini and it is still widely performed in many orthopedic center worldwide.

Custom-Made Devices Represent a Promising Tool to Increase Correction Accuracy of High Tibial Osteotomy: A Systematic Review of the Literature and Presentation of Pilot Cases with a New 3D-Printed System.

BACKGROUND: The accuracy of the coronal alignment corrections using conventional high tibial osteotomy (HTO) falls short, and multiplanar deformities of the tibia require consideration of both the coronal and sagittal planes. Patient-specific instrumentations have been introduced to improve the control of the correction. Clear evidence about customized devices for HTO and their correction accuracy lacks. METHODS: The databases PUBMED and EMBASE were systematically screened for human and cadaveric studies about the use of customized devices for high tibial osteotomy and their outcomes concerning correction accuracy. Furthermore, a 3D-printed customized system for valgus HTO with three pilot cases at one-year follow-up was presented. RESULTS: 28 studies were included. The most commonly used custom-made devices for HTO were found to be cutting guides. Reported differences between the achieved and targeted correction of hip-knee-ankle angle and the posterior tibial slope were 3° or under. The three pilot cases that underwent personalized HTO with a new 3D-printed device presented satisfactory alignment and clinical outcomes at one-year follow-up. CONCLUSION: The available patient-specific devices described in the literature, including the one used in the preliminary cases of the current study, showed promising results in increasing the accuracy of correction in HTO procedure.

Ecological Impact of End-of-Life-Tire (ELT)-Derived Rubbers: Acute and Chronic Effects at Organism and Population Levels.

Considering the large amount of tires that reach the end of life every year, the aim of this study was the evaluation of both acute and chronic effects of end-of-life-tire (ELT)-derived rubber granules (ELT-dg) and powder (ELT-dp) on a freshwater trophic chain represented by the green alga Pseudokirchneriella subcapitata, the crustacean Daphnia magna and the teleost Danio rerio (zebrafish). Adverse effects were evaluated at the organism and population levels through the classical ecotoxicological tests. Acute tests on D. magna and D. rerio revealed a 50% effect concentration (EC50) > 100.0 mg/L for both ELT-dg and ELT-dp. Chronic exposures had a lowest observed effect concentration (LOEC) of 100.0 mg/L for both ELT-dg and ELT-dp on P. subcapitata grow rate and yield. LOEC decreased in the other model organisms, with a value of 9.8 mg/L for D. magna, referring to the number of living offspring, exposed to ELT-dg suspension. Similarly, in D. rerio, the main results highlighted a LOEC of 10.0 mg/L regarding the survival and juvenile weight parameters for ELT-dg and a LOEC of 10.0 mg/L concerning the survival and abnormal behavior in specimens exposed to ELT-dp. Tested materials exhibited a threshold of toxicity of 9.8 mg/L, probably a non-environmental concentration, although further investigations are needed to clarify the potential ecological impact of these emerging contaminants.

Pelvic floor biofeedback is an effective treatment for severe bloating in disorders of gut-brain interaction with outlet dysfunction.

BACKGROUND: The pathophysiology of bloating is partially understood. We investigated in patients with disorders of gut-brain interaction (DGBI) the relationship between severity of bloating, abdominal girth changes and defecation pattern, and the efficacy of pelvic floor biofeedback treatment on bloating. METHODS: Disorders of gut-brain interaction patients with severe bloating as the main complaint were prescribed 2 weeks dietary advice and underwent abdominal girth measurements. At the first visit, all patients underwent a questionnaire on the subjective improvement of bloating, a (0-100) VAS abdominal bloating, and abdominal girth measurement. Patients reporting inadequate bloating relief underwent a standardized balloon expulsion test. Furthermore, they were invited to undergo pelvic floor electromyography and biofeedback treatment previously used for constipation due to dyssynergic defecation. The primary outcome was bloating improvement on a 5-point Likert scale. The secondary outcomes were the effect of diet intervention and pelvic floor biofeedback treatment on bloating severity and quality of life changes as well as the effect of pelvic floor biofeedback treatment on BET and EMG on straining. KEY RESULTS: One hundred and fifty six patients (129 F, 39.3 ± 11.7 mean age) completed the 2-week run-in period. 105 patients were diet non-responder and underwent balloon expulsion test, with the vast majority (64%) failing the test. Patients who scored higher bloating on VAS had a significant association with failed balloon expulsion test (adjusted B 0.4 [95% CI 10.8-25.7], p < 0.0001). 63% agreed to perform pelvic floor biofeedback treatment at Verona center, 54% became responders reporting fair or major improvement/cure (ITT analysis, McNemar test, p < 0.0001), and all of them showed a 50% decrease in bloating severity. CONCLUSIONS AND INFERENCES: Disordered defecation is a prevalent etiology in DGBI patients with bloating unresponsive to conservative measures; pelvic floor biofeedback treatment to improve the defecation effort significantly relieved bloating (http://www.isrctn.com, ISRCTN17004079).

Hand hygiene determinants of informal caregivers in hospitals under Pender's perspective / Determinantes de higienización de manos de cuidadores informales en hospitales bajo la perspectiva de Pender / Determinantes de higienização das mãos de cuidadores informais em hospitais sob a perspectiva de Pender

ABSTRACT Objectives: to analyze hand hygiene determinants of informal caregivers in a hospital environment. Methods: qualitative study conducted with 55 caregivers at a university hospital in the Northeast of Brazil. A semi-structured instrument was used, adapted from Nola Pender's Health Promotion Model, from which the deductive categories were derived. Results: the general behavior included hand hygiene before meals and after using the bathroom. Sensitivity to the requirements for hand hygiene was observed, but the barriers and self-efficacy consisted of the availability of soap or alcohol-based hand sanitizers, the lack of knowledge on the importance of and forgetfulness of the practice. The reinforcement on the importance of the practice and being in a contaminated environment were influencers, and commitment, warnings, and training were indispensable. Conclusions: benefits related to protection from infections were seen as positive determinants for hand hygiene adherence. For non-adherence, factors such as lack of sanitizing supplies, ignorance towards the importance of the activity, and forgetfulness stood out.

Nutrition and Healthy Aging: Prevention and Treatment of Gastrointestinal Diseases.

Nutritional well-being is a fundamental aspect for the health, autonomy and, therefore, the quality of life of all people, but especially of the elderly. It is estimated that at least half of non-institutionalized elderly people need nutritional intervention to improve their health and that 85% have one or more chronic diseases that could improve with correct nutrition. Although prevalence estimates are highly variable, depending on the population considered and the tool used for its assessment, malnutrition in the elderly has been reported up to 50%. Older patients are particularly at risk of malnutrition, due to multiple etiopathogenetic factors which can lead to a reduction or utilization in the intake of nutrients, a progressive loss of functional autonomy with dependence on food, and psychological problems related to economic or social isolation, e.g., linked to poverty or loneliness. Changes in the aging gut involve the mechanical disintegration of food, gastrointestinal motor function, food transit, intestinal wall function, and chemical digestion of food. These alterations progressively lead to the reduced ability to supply the body with adequate levels of nutrients, with the consequent development of malnutrition. Furthermore, studies have shown that the quality of life is impaired both in gastrointestinal diseases, but especially in malnutrition. A better understanding of the pathophysiology of malnutrition in elderly people is necessary to promote the knowledge of age-related changes in appetite, food intake, homeostasis, and body composition in order to better develop effective prevention and intervention strategies to achieve healthy aging.

The Lateral Femoral Notch Sign Is Correlated With Increased Rotatory Laxity After Anterior Cruciate Ligament Injury: Pivot Shift Quantification With A Surgical Navigation System.

BACKGROUND: The lateral femoral notch sign (LNS) is a bony impression on the lateral femoral condyle correlated with anterior cruciate ligament (ACL) injury. Its presence is associated with lateral meniscal injury and higher cartilage degradation on the lateral femoral condyle. PURPOSE/HYPOTHESIS: The purpose was to investigate the effect of the presence and magnitude of LNS on rotatory instability. The hypothesis was that a positive LNS is correlated with a high-grade pivot shift (PS). STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: A total of 90 consecutive patients with complete ACL tears between 2013 and 2017 underwent intraoperative kinematic evaluation with the surgical navigation system and were included in the present study. The same surgeon performed a standardized PS under anesthesia. The PS was quantified through the acceleration of the lateral compartment during tibial reduction (PS ACC) and the internal-external rotation (PS IE). Presence and depth of LNS were evaluated on sagittal magnetic resonance images (1.5-T). RESULTS: In 47 patients, the LNS was absent; in 33, the LNS depth was between 1 mm and 2 mm; and in 10 patients, it was deeper than 2 mm. Patients with a notch deeper than 2 mm showed increased PS ACC and PS IE compared with the group without the LNS. However, no significant differences were present between the group with a notch between 1 and 2 mm and the patients without LNS. Receiver operating characteristic curve analysis showed that 2 mm was the most predictive cutoff value to identify the "high-grade rotatory instability" group, with an accuracy of 77.8% and 74.4% and a specificity of 95.5% and 93.9% referred to the PS ACC and PS IE, respectively. CONCLUSION: The presence of a lateral LNS deeper than 2 mm could be used for the preoperative identification of patients with a high risk of increased rotatory instability.

Female adolescents and young women previously treated for pediatric malignancies: assessment of ovarian reserve and gonadotoxicity risk stratification for early identification of patients at increased infertility risk.

OBJECTIVES: Childhood and adolescent cancer survivors (CACSs) are at risk of adverse reproductive outcomes. Assessment of follicle-stimulating hormone (FSH) levels is the most common test used to diagnose premature ovarian insufficiency (POI) whereas anti-m|llerian hormone (AMH) and antral follicle count (AFC) have been proposed as ovarian reserve markers. We assessed the correlation between these markers and treatment gonadotoxicity risk (GR) in CACSs. METHODS: A total of 55 female CACSs were enrolled. GR was graded as low, medium, or high according to classifications based on disease and treatments and on cyclophosphamide equivalent dose score. FSH, AMH, and AFC were determined. POI was defined by amenorrhea and FSH>30 IU/L. For remaining patients, diminished ovarian reserve (DOR) was defined by AMH<5th centile. FSH and AFC cut-offs proposed in the literature as DOR markers were also considered (FSH>10 IU/L or >95th centile; AFC<8 or <5th centile). RESULTS: Ovarian reserve results to be compromised in 23 (41.8%) patients: 14 with DOR and 9 with an established POI. Results showed GR classifications to be a good predictor of ovarian reserve, with significantly lower AMH and AFC in the high-risk groups. AFC resulted to be directly correlated with AMH (r=0.75, p<0.001). CONCLUSIONS: In CACSs, GR classifications correlate with post-treatment AMH and AFC. These are useful tools in the early identification of young patients with DOR, who may benefit from reproductive and fertility preservation counseling. Further studies are needed to determine the rate and time of progression from DOR to POI in this population.

The sagittal geometry of the trochlear groove could be described as a circle: an intraoperative assessment with navigation.

PURPOSE: The aim of this study was to describe the sagittal geometry of the trochlear groove in patients who underwent primary TKA, based on intraoperative data acquired with a navigation system. METHODS: Intraoperative navigation data were collected from 110 patients. All operations were guided by a non-image-based navigation system (BLU-IGS, Orthokey Italia Srl). The trochlear groove has been described on the three anatomical planes; in particular, on the sagittal plane the hypothesis has been verified that the acquired points are referable to a circle. Using the data collected during intraoperative navigation, possible correlation between the radius of the trochlear groove and other femur dimension (length, AP dimension) was analyzed; the orientation of the trochlear sulcus with respect to the mechanical axis and the posterior condyle axis was analyzed too, searching for possible correlation between groove alignment (frontal and axial) or groove radius and the hip-knee-ankle (HKA). RESULTS: The average radius of curvature of the femoral trochlea was 25.5 ± 5.6 mm; the difference was not statistically significant between the men and women (n.s. p value). No correlation was found between the trochlear groove radius and the femur length (r = - 0.02) or the HKA-phenotypes (r = 0.03) and between the groove alignment and HKA-phenotypes. On axial plane, the trochlear groove was 3.2° ± 4.3° externally rotated, with respect to the posterior condylar axis; on frontal plane, the trochlear groove was 3.9° ± 5.3° externally rotated, with respect to the mechanical axis. In both cases, no statistically significant differences were found between male and female and between left and right limb (p > 0.05). CONCLUSION: The present study shows that the sagittal plane geometry of the femoral trochlea in patients affected by osteoarthritis could be described accurately as a circle. The acquisition of the trochlear morphology intraoperatively can lead to more anatomically shape definition, to investigate deeper its radius of curvature and geometry. Trochlear shape could be used as landmarks for femoral component positioning, thus customizing the implant design, optimize the outcomes and improving anterior knee pain after TKA. LEVEL OF EVIDENCE: IV.

The 90-day Readmission Rate after Single-Bundle ACL Reconstruction Plus LET: Analysis of 2,559 Consecutive Cases from a Single Institution.

The aim of the present study is to examine the readmission rate within 90 days of a cohort of patients, who underwent an arthroscopic anterior cruciate ligament (ACL) reconstruction with a lateral extraarticular tenodesis, from a single highly specialized sports traumatology department. From our institutional database, we identified 2,559 patients (78.5% males and 21.5% females, with a mean age at surgery of 30.9 ± 11.5 years) who underwent primary ACL reconstruction with the same "over-the-top" technique plus lateral extraarticular tenodesis (LET) from January 2010 to December 2017. From this count, we extracted all patients who were readmitted within 90 days and focused on causes of readmission and reoperation rate. Moreover, a multivariate logistic regression was performed to identify possible variables, such as gender, age, and concomitant meniscus surgery, which could predict the risk of early readmission. From the aforementioned cohort, 58 patients (2.27%) were readmitted within 90 days from surgery after a mean time of 31 ± 23 days. The most common cause of readmission was fever and knee swelling (0.78%), followed by superficial infection (0.63%), deep infection (0.55%), and joint stiffness (0.23%). The patients' age and meniscal lesions requiring concomitant arthroscopic treatment were found to be correlated to an increased risk of early readmission. Superficial infections were more common in female patients (odds ratio [OR] = 3.01), whereas the meniscal treatment was also a significant risk factor specifically for deep infections (OR = 3.56). In conclusion, this technique of arthroscopic ACL reconstruction with LET showed a low readmission rate within 90 days from surgery. However, patients and physicians should be aware of the risk of serious complications, such as deep and superficial infections, mostly in female patients and in cases of concurrent meniscal treatments. This is a Level IV, retrospective case series study.

Differences between quality of life and occupational coping of tenured and outsourced nurses.

OBJECTIVES: To compare the relation of quality of life to occupational coping and verify the association of these indicators with sociodemographic variables of tenured and outsourced nurses. METHODS: Cross-sectional study, carried out from June to November 2014, with 145 outsourced nurses and 45 tenured nurses. We applied an identification instrument (WHOQOL-bref) and Occupational Coping Scale. Student's t-tests and Pearson's correlation coefficient were used. RESULTS: Tenured nurses had better quality of life (p=0.011) and a mean in the Avoidance factor with a strong correlation (p=0.001). Female public servants (p=0.006; p<0.0001), between 40 and 66 years old (p=0.005; p=0.031), specialists (p=0.028; p=0.005), with a family income from 2.5 to 6.8 minimum wages (p=0.021; p=0.006) and working in the morning or afternoon (p=0.043; p=0.020) and morning and afternoon (p=0.038; p=0.007) showed a difference in quality of life and in Avoidance factor, respectively. CONCLUSION: Tenured nurses demonstrated better quality of life, and some variables trigger differences in the groups, demonstrating the need to promote occupational health.

Long-term Outcomes and Survivorship of Fresh-Frozen Meniscal Allograft Transplant With Soft Tissue Fixation: Minimum 10-Year Follow-up Study.

BACKGROUND: Meniscal allograft transplant (MAT) is considered an effective procedure for reducing pain and improving knee function. Nevertheless, the current knowledge regarding the results of MAT is limited to short- to mid-term follow-up studies, especially for arthroscopic techniques. PURPOSE: To evaluate the long-term clinical outcomes, reoperations, and failures with a minimum follow-up of 10 years after fresh-frozen MAT performed arthroscopically with soft tissue fixation. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 46 patients (age, 36.6 ± 10.6 years; 36 male, 10 female) who underwent medial MAT (n = 27) or lateral MAT (n = 19) with a minimum 10-year follow-up were evaluated with the Lysholm score, Knee injury and Osteoarthritis Outcome Score (KOOS), visual analog scale for pain, and Tegner score. Surgical failure was defined as the need for partial or total graft removal (meniscectomy or knee replacement), and clinical failure was defined as the need for partial or total graft removal in addition to a poor Lysholm score (<65 points) at final follow-up. Survival analysis was performed with Kaplan-Meier curve, and clinical scores were analyzed based on the Patient Acceptable Symptom State (PASS) for MAT. RESULTS: 10-year survival and clinical data were available for 38 patients. Because 6 meniscectomies were required, the rate of survival free from surgical failure was 91% at 5 years and 86% at 10 years. Lower survival was reported in lateral MAT (73%) compared with medial MAT (96%). Because a further 4 patients had poor Lysholm scores, the rate of survival free from surgical and clinical failure was 87% at 5 years and 70% at 10 years. The average Lysholm score at final follow-up was 82 ± 20, and 60% to 82% of patients achieved PASS of the various KOOS subscales. The Tegner score and the KOOS Sport score significantly decreased from mid-term to long-term evaluation (P < .001 and P < .05, respectively). Other KOOS subscales and the Lysholm score remained stable at long-term evaluation. No significant differences were found between isolated MAT or combined MAT regarding subjective scores, surgical failures, or clinical failures. CONCLUSION: Up to 10 years after surgery, 86% of fresh-frozen MATs with soft tissue fixation were still in situ, and satisfactory clinical results were present for about 70% of patients. Decline of clinical outcomes from midterm to long term was noted only in sports-related scores. A higher number of overall reoperations was noted in female patients, whereas a higher risk of failure was present in the patients with lateral MAT.

Graft-Preserving Arthroscopic Debridement With Hardware Removal Is Effective for Septic Arthritis After Anterior Cruciate Ligament Reconstruction: A Clinical, Arthrometric, and Magnetic Resonance Imaging Evaluation.

BACKGROUND: Arthroscopic debridement with graft preservation has been advocated as the treatment of choice for septic arthritis after anterior cruciate ligament (ACL) reconstruction, but no previous studies have investigated if hardware removal, while retaining the graft in situ, improves the success rate. Moreover, it is unclear whether the premature removal of fixation devices may affect graft integration and knee stability. PURPOSE/HYPOTHESIS: The purpose was to assess the clinical and functional outcomes of patients with septic arthritis after ACL reconstruction who underwent arthroscopic debridement, while retaining the graft in situ but removing fixation devices, and to determine if premature hardware removal affects graft integrity and function. The hypothesis was that arthroscopic debridement with hardware removal would be effective in eradicating infections while not compromising graft integration and function. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: From a cohort of 2384 cases of arthroscopic ACL reconstruction, 24 patients with postoperative septic arthritis were included for the analysis; 18 patients were available for a clinical evaluation using the International Knee Documentation Committee (IKDC) form, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lysholm score, and Tegner score at a minimum 12-month follow-up. Knee laxity was assessed clinically with standardized manual laxity tests and instrumentally using an arthrometer and a triaxial accelerometer. Additionally, 3-T magnetic resonance imaging (MRI) at final follow-up was performed, focusing on the graft signal, the cartilage status, and the occurrence of arthrofibrosis. RESULTS: Eradication of the infection was achieved in all cases, and only 1 graft removal was performed because of insufficient tension. Among the remaining 23 patients, a single arthroscopic debridement procedure with hardware removal while preserving the graft was effective in 21 cases (91%) at a mean of 30 ± 37 days from ACL reconstruction to debridement. At last follow-up, 2 patients required a further ACL revision procedure. The mean IKDC, WOMAC, Lysholm, and Tegner scores of the patients available for the clinical evaluation were 75 ± 19, 90 ± 8, 79 ± 21, and 6 ± 2, respectively. No abnormal laxity was reported on manual testing, and arthrometric and accelerometer tests also demonstrated good knee stability (mean KT-1000 arthrometer side-to-side difference was 1.6 ± 1.2 mm at manual maximum force). On MRI, a good graft signal was found in 50% of cases, while concomitant signs of arthrofibrosis were detected in 81% of patients. Severe cartilage defects (International Cartilage Repair Society grade ≥3) were reported in 63% of cases. CONCLUSION: Arthroscopic debridement with hardware removal was effective in the eradication of infections after ACL reconstruction with extra-articular fixation while preserving graft integrity without compromising knee stability. Patients and surgeons should be aware of complications that might affect the outcome, particularly arthrofibrosis and chondrolysis.
