RESUMO
OBJECTIVES: This study aimed to analyze the association between physical therapists' recommended number of visits for a full recovery from common orthopedic injuries/surgeries and the extent of insurance coverage for these visits. METHODS: A prospective observational study was conducted with board-certified physical therapists. A qualitative questionnaire was used to gather physical therapists' demographics and the recommended number of physical therapy visits to achieve a full recovery after 11 common orthopedic diagnoses. Physical therapists also were asked to report whether they believe that insurance provides an adequate number of visits overall. In addition to the qualitative survey, insurance coverage details of major Alabama companies were obtained for comparison. Descriptive statistics of the participating therapists were analyzed for sex, age, degree/training, and years of experience. Kruskal-Wallis statistics were used to analyze variance between the aforementioned groupings when compared with the reported average number of sessions. RESULTS: The survey (N = 251) collected data on the average number of physical therapy sessions that are necessary for a complete recovery as recommended by physical therapists for 11 common orthopedic diagnoses. From this survey, the average number of necessary visits ranged from 11.3 visits (ankle sprains) to 37.3 visits (anterior cruciate ligament reconstruction), with the overall average number of visits being 23.8. Only 24% of physical therapists believed that insurance companies provided enough coverage. Insurance coverage varied but often required additional procedures to allocate the adequate number of visits for the studied orthopedic pathologies. CONCLUSIONS: The majority of practicing physical therapists in Alabama perceive insufficient insurance coverage for physical therapy visits for most orthopedic diagnoses. This study has implications for healthcare decision making and patient-centered rehabilitation goals. Physicians and physical therapists can use this information to optimize treatment decisions and rehabilitation goals. Patients will benefit from improved physical and economic well-being. This study has the potential to drive further research and influence national insurance policies to better serve patients' needs.

PURPOSE: The purpose of this systematic review is to consolidate outcomes of obese patients undergoing high tibial osteotomy and to investigate the effect of obesity on postoperative outcomes, including symptomatic relief and time to conversion to arthroplasty. METHODS: Medline, Embase and Cochrane Library were searched from database inception up to April 2023 according to PRISMA guidelines by two reviewers. Search terms including 'obesity', 'BMI', 'osteotomy' and 'high tibial osteotomy (HTO)' were included to identify all relevant articles. Only studies that explicitly reported outcomes for obese patients were included. Disagreements in study inclusion or quality assessment were resolved by a senior third reviewer. Metrics compared include time to arthroplasty, preoperative and postoperative mechanical tibiofemoral angle (mTFA), patient-reported satisfaction scores and postoperative complications. RESULTS: Nine studies comparing 973 patients were included. The mean age was 52.7 ± 4.2 years old and 38.4% were male. Six studies performed the medial opening-wedge HTO, and three utilized the medial wedge closing technique. Most studies indicated significant improvement following surgical intervention with satisfactory outcomes in obese and nonobese patients. In addition, differences in complication rates were minimal between obese and nonobese patients (n.s.), while functional scores did not vary significantly. Conversion to total knee arthroplasty was not found to increase in obese patients (n.s.). CONCLUSION: Obesity does not appear to carry a greater complication risk or worse outcomes following high tibial osteotomies, and surgeons should consider HTO a viable option for young obese patients with symptomatic unicompartmental chondral wear with coronal limb malalignment. LEVEL OF EVIDENCE: Level IV.

OBJECTIVE: Although recent trends from the Accreditation Council for Graduate Medical Education (ACGME) present encouraging growth of female representation in sports medicine, the field is still lagging behind other specialties. This study investigates gender disparities among physicians providing care for professional sports teams in male and female sports leagues. DESIGN: Information regarding physicians providing sports medicine care to professional teams obtained by database queries (May 2021). Chi-square analysis compared gender data of orthopaedic team physicians with American Orthopaedic Society for Sports Medicine (AOSSM) and American Academy of Orthopaedic Surgeons (AAOS) membership, residency, and fellowship census data. Primary care sports medicine physicians were compared with American Medical Society for Sports Medicine (AMSSM) and primary-care sports medicine fellowship census data. SETTING: Professional sports health care. STUDY POPULATION: Professional league physicians. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Gender, residency, and fellowship training of professional league physicians. RESULTS: Among a total of 608 team physicians, 572 (93.5%) were male and 40 (6.5%) were female. Orthopedic surgeons comprised 64.7% of the physicians. Fourteen (3.6%) team orthopedic surgeons were female. Thirty-five percent of team physicians were primary care sports medicine physicians. Twenty-six primary care sports medicine physicians (11.6%) were female. Orthopaedic female team physician representation overall was comparable with AOSSM and AAOS membership but significantly less than orthopaedic surgery residents and sports medicine fellows ( P < 0.01). Women's National Basketball Association orthopaedic team physicians were more represented than female membership among AOSSM, AAOS, and orthopaedic sports medicine fellows ( P < 0.01). Except for the WNBA, Premiere Hockey Federation, National Women's Soccer League, and United States Football League, female primary care sports medicine physicians were underrepresented in professional sports compared with AMSSM membership and primary care sports fellows ( P < 0.01). CONCLUSION: Overall, female representation is poor among orthopaedic surgeons and primary care physicians providing sports medicine care to professional teams. Leagues encompassing female athletes tend to have better representation of female physicians. LEVEL OF EVIDENCE: IV.

OBJECTIVES: Reconstruction for a chronic patellar tendon rupture in a native knee is an uncommon surgical procedure. Although there have been case series investigating patient-reported outcomes, there is no systematic review of these studies to date. The purpose of this review is to synthesize the literature on this procedure to better understand its outcomes, complications, and surgical technique options. METHODS: A systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify studies that reported outcomes and techniques of patellar tendon reconstruction for chronic disruption in native knees. Searches were conducted through MEDLINE using PubMed, Cochrane Database of Systematic Reviews, and clinicaltrials.gov. RESULTS: Ten studies with 103 patients and 105 knees were included. Results for nonnative (arthroplasty) knees were excluded. The mean patient age was 40.3 years, and the mean postsurgical follow-up time was 53.8 months. Of the 105 knees, 75% received a hamstring tendon graft, whereas 13% received a bone-tendon-bone graft and 7% received a whole extensor mechanism allograft. The mean preoperative range of motion was 113.8°, which improved to 126.0° postoperatively. The mean preoperative Lysholm score was 58.6, which improved to 86.0 postoperatively; 100% of patients returned to their normal work activities and 76% returned to their prior level of physical activity. There were no major complications reported in any of the included studies. CONCLUSIONS: Chronic patellar tendon disruption in a native knee is an uncommon injury that can result in significant limitations for patients. Although more research is needed to better elucidate which graft is best, outcomes after patellar tendon reconstruction for chronic tears appear to be satisfactory with current techniques.

OBJECTIVES: Patients with private healthcare plans often defer nonemergent or elective procedures toward the end of the year once they have met their deductible. No previous studies have evaluated how insurance status and hospital setting may affect surgical timing for upper extremity procedures. Our study aimed to evaluate the influence of insurance and hospital setting on end-of-the-year surgical cases for elective carpometacarpal (CMC) arthroplasty, carpal tunnel, cubital tunnel, and trigger finger release, and nonelective distal radius fixation. METHODS: Insurance provider and surgical dates were gathered from two institutions' electronic medical records (one university, one physician-owned hospital) for those undergoing CMC arthroplasty, carpal tunnel release, cubital tunnel release, trigger finger release, and distal radius fixation from January 2010 to December 2019. Dates were converted into corresponding fiscal quarters (Q1-Q4). Using the Poisson exact test, comparisons were made between the case volume rate of Q1-Q3 and Q4 for private insurance and then for public insurance. RESULTS: Overall, case counts were greater in Q4 than the rest of the year at both institutions. There was a significantly greater proportion of privately insured patients undergoing hand and upper extremity surgery at the physician-owned hospital than the university center (physician owned: 69.7%, university: 50.3%; P < 0.001). Privately insured patients underwent CMC arthroplasty and carpal tunnel release at a significantly greater rate in Q4 compared with Q1-Q3 for both institutions. Publicly insured patients did not experience an increase in carpal tunnel releases during the same period at both institutions. CONCLUSIONS: Privately insured patients underwent elective CMC arthroplasty and carpal tunnel release procedures in Q4 at a significantly greater rate than publicly insured patients. This finding suggests private insurance status, and potentially deductibles, influence surgical decision making and timing. Further work is needed to evaluate the impact of deductibles on surgical planning and the financial and medical impact of delaying elective surgeries.

OBJECTIVES: Osteoarthritis (OA) is one of the most prevalent musculoskeletal ailments worldwide. Numerous conservative therapies exist, but evidence for such treatments remains conflicting. Recently, there has been growing interest surrounding bioactive sleeves for managing knee arthritis; however, the literature on their efficacy for relieving pain and improving function in the setting of knee OA is limited. As such, we sought to investigate the effect of a bioactive sleeve on patient-reported outcome measures in a small cohort of patients with OA. METHODS: Patients with knee OA were given a bioactive sleeve (Reparel, Chico, CA) and asked to refrain from lifestyle modifications and intraarticular corticosteroid injections. Lysholm Knee Score, Oxford Knee Score, Knee Injury and OA Outcome Score (KOOS), Single Assessment Numeric Evaluation, and Visual Analog Scale score were obtained at baseline, 2 weeks, 6 weeks, and 3 months. OA severity was evaluated using the Kellgren and Lawrence (KL) classification system. The Wilcoxon signed rank test was used to compare baseline patient-reported outcomes with 2-week, 6-week, and 3-month time points. Bivariate correlation was used to evaluate the relation between patient-reported outcome measures and KL classification. RESULTS: The cohort was composed of 14 participants-4 males and 10 females-with a mean age of 62.2 ± 13.2 years and a body mass index of 33.7 ± 5.8. The average KL grade was 2.9 (range 2-4). KOOS pain, symptoms, activities of daily living, and quality of life increased significantly at 2 weeks, 6 weeks, and 3 months. KOOS sport and recreation significantly increased at 3 months. The Oxford Knee Score was significantly greater at 2 weeks, 6 weeks, and 3 months. The Lysholm Knee Score was significantly greater at 6 weeks and 3 months. The Single Assessment Numeric Evaluation attained significant improvement at 3 months, and the Visual Analog Scale improvement was significant at 2 weeks. No statistically significant difference was attained with University of California at Los Angeles activity score. Outcome scores did not correlate with KL classification. CONCLUSIONS: These data suggest that a bioactive sleeve may improve patient-reported pain, symptoms, and function in the setting of knee OA. Further research is needed to better understand the role of bioactive sleeves for patients with knee arthritis.

BACKGROUND: Outcomes following arthroscopic excision of calcific tendonitis and arthroscopic rotator cuff repair (CT-ARCR) are relatively limited without comparison analysis to standard arthroscopic rotator cuff repair (ARCR). The purpose of this study was to evaluate patient-reported outcomes (PROs) after CT-ARCR compared against a matched cohort who received standard ARCR. METHODS: An institutional review board-approved retrospective review was performed for patients aged 18-80 years receiving CT-ARCR by a single surgeon from 2006-2018. These were matched 1:3 with patients receiving ARCR. Patients with concurrent labral repair, subscapularis repair, or glenohumeral joint arthritis procedures; refusal to participate; deceased; inadequate contact information; or those with inadequate records were excluded. PROs included Short Form-12 Physical Component Summary (SF-12 PCS) score; American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES); Single Assessment Numeric Evaluation (SANE); Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (QuickDASH); patient satisfaction; activity level/symptoms; and sport participation scores. RESULTS: 21 CT-ARCR patients (mean age 50 years, range 36-62) and 54 ARCR patients (mean age 52 years, range 19-77) were included. Minimum 2-year follow-up was obtained in 18 of 21 (86%) CT-ARCR (mean 5.9 years) and 45 of 54 (83%) ARCR patients (mean 5.6 years). CT-ARCR patients improved pre- to postoperation in mean SF-12 PCS (41.1 to 50.0), ASES (54.2 to 94.0), and QuickDASH (54.2 to 94.0). SANE score improvements (57.6 to 82.8) were not significant. ARCR controls improved pre- to postoperation in mean SF-12 PCS (41.4 to 49.0), ASES (59.4 to 88.0), QuickDASH (35.1 to 13.8), and SANE scores (52.6 to 80.8). Pre- to postoperative pain during recreation and sport participation similarly improved in both groups. The only postoperative difference observed between CT-ARCR and ARCR was better patient satisfaction with CT-ARCR (9.7 vs. 8.3). CONCLUSION: CT-ARCR results in excellent PROs, activity symptoms, and sports participation at final follow-up. CT-ARCR results were comparable to patients who received conventional ARCR for similar-sized rotator cuff tears that did not have calcific tendonitis.

HYPOTHESIS: The purpose of this study was to report return to sport, patient-reported outcomes (PROs), subjective outcomes, and complications or failures in patients who underwent open Latarjet surgery. METHODS: Patients who underwent open Latarjet surgery performed by 2 fellowship-trained surgeons between August 2006 and November 2018 were included. Prospectively collected data were reviewed. Recurrent instability and revision surgical procedures were recorded. Subjective outcomes included return to sport and fear of reinjury or activity modification as a result of patients' instability history. PROs included the American Shoulder and Elbow Surgeons (ASES) score, Short Form 12 Physical Component Summary score, Single Assessment Numeric Evaluation score, Quick Disabilities of the Arm, Shoulder and Hand score, and satisfaction. Age, sex, sports participation, pain, primary vs. revision surgery (prior failed arthroscopic or open Bankart repair), dislocation number, glenoid bone loss, glenoid track concept, and projected glenoid track were evaluated. Failure was defined as an ASES score <70, recurrent dislocation, or revision instability surgery. RESULTS: A total of 126 shoulders (125 patients) met the inclusion criteria, with a mean age of 28.1 years (range, 15-57 years). Of 126 shoulders, 7 (5.5%) underwent additional procedures prior to final follow-up and were excluded from outcome analyses; failure occurred in 6 of these shoulders. Mean follow-up data at 3.7 years (range, 2-9.3 years) were attained in 86.6% of patients (103 of 119). All PROs significantly improved from preoperative baseline (ASES score, from 69.7 to 90.2; Single Assessment Numeric Evaluation score, from 55.8 to 85.9; and Quick Disabilities of the Arm, Shoulder and Hand score, from 28.4 to 10.5). PROs did not differ based on sex, sports participation type, dislocation with or without sports, primary vs. revision procedure, and preoperative dislocation number. No correlations existed between PROs and age, glenoid bone loss, or number of previous surgical procedures. On-track lesions (50 of 105, 47.6%) and projected on-track lesions (90 of 105, 85.7%) correlated with better patient satisfaction but not PROs. Despite not having recurrences, 63 of 99 patients (63.6%) reported activity modifications and 44 of 99 patients (44.4%) feared reinjury. These groups had statistically worse PROs, although the minimal clinically important difference was not met. Return to sport was reported by 97% of patients (86 of 89), with 74% (66 of 89) returning at the same level or slightly below the preinjury level. Revision stabilization surgery was required 6 of 126 cases (4.8%), and 6 of 103 shoulders (5.8%) had ASES scores <70. CONCLUSION: The open Latarjet procedure led to significant improvements in all PROs, and overall, 97% of patients returned to sport. Fear of reinjury and activity modifications were common after open Latarjet procedures but did not appear to affect clinical outcomes. On-track and projected on-track measurements correlated with better patient satisfaction but not improved PROs.

BACKGROUND: Anterior cruciate ligament injuries and anterior cruciate ligament reconstructions (ACLRs) are common, especially in adolescent patients. Recovery of strength, jumping performance, and perceived/subjective function are often used to make a return to sports decisions after injury. It is unknown how skeletal maturity may influence strength recovery after ACLR. The purpose of this study was to compare the strength and patient-reported outcomes in adolescent ACLR patients with and without open distal femur and proximal tibia physes. METHODS: One hundred seventeen consecutive patients under the age of 18 were referred for routine strength and subjective outcomes evaluation following ACLR, 100 were included in the final analyses after excluding those with prior injuries, those tested outside for 4 to 12 month postoperative window, and those with incomplete clinical data. All study patients completed patient-reported outcomes, and underwent isometric and isokinetic testing of knee extensor and flexor strength to calculate normalized peak torque and limb symmetry. Statistical analyses were performed on all outcomes data using a 2×2 (physeal status: open, closed; and sex: male, female) with analysis of covariance where age and preoperative activity level were used as covariates. RESULTS: A significant interaction between sex and physeal status for isokinetic knee extension peak torque and isometric knee extension peak torque, and limb symmetry index was found. This indicated that males with open physes were stronger and more symmetric than males with closed physes and females with open physes at ~6 months post-ACLR. There were no differences between sexes for patients with closed physes. No interactions were observed for flexion strength. Male patients and patients with open physes had higher perceived knee function compared with their corresponding counterparts. CONCLUSIONS: After ACLR, adolescent patients with open physes had higher quadriceps strength compared with patients with closed physes. Overall, those skeletally less mature patients actually fared better on the functional strength tests, suggesting that functional recovery is not hindered by the presence of an incompletely closed physis. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

BACKGROUND: The relationship between surgeon and hospital charges and payments for total shoulder arthroplasty (TSA) has not been well examined. The goal of this study was to report trends and variation in hospital charges and payments compared with surgeon charges and payments for TSA. METHODS: The 5% Medicare sample was used to capture hospital and surgeon charges and payments for TSA from 2005 to 2014. Two values were calculated: (1) the charge multiplier (CM), which is the ratio of hospital to surgeon charges, and (2) the payment multiplier (PM), which is the ratio of hospital to surgeon payments. The year-to-year variation and regional trends in patient demographic characteristics, Charlson Comorbidity Index, length of stay (LOS), CM, and PM were evaluated. RESULTS: The study included 10,563 patients. Per-patient hospital charges increased from $33,836 to $67,177 (99.9% increase), whereas surgeon charges increased from $4284 to $4674 (9.1% increase) (the CM increased from 7.9 to 14.4, P < .0001). Hospital payments increased from $8758 to $14,167 (61.8%), whereas surgeon payments decreased from $1028 to $884 and the PM increased from 8.5 to 16.0 (P < .0001). The LOS decreased significantly (P < .0001), whereas the Charlson Comorbidity Index remained stable. Both the CM (r2 = 0.931) and PM (r2 = 0.9101) were strongly negatively associated with the LOS. CONCLUSIONS: Hospital charges and payments relative to surgeon charges and payments have increased substantially for TSA despite stable patient complexity and a decreasing LOS. These results encourage the need for future studies with detailed cost analyses to identify the reasons for hospital and surgeon financial malalignment.

BACKGROUND: Many states have certificate-of-need (CON) programs requiring governmental approval to open or expand healthcare services, with the goal of limiting cost and coordinating utilization of healthcare resources. The purpose of the present study was to evaluate the associations between these state-level CON regulations and total hip arthroplasty (THA). METHODS: States were designated as CON or non-CON based on existing laws. The 100% Medicare Standard Analytic Files from 2005 to 2014 were used to compare THA procedure volumes, charges, reimbursements, and distribution of procedures based on facility volumes between the CON and non-CON states. Adverse postoperative outcomes were also analyzed. RESULTS: The per capita incidence of THA was higher in non-CON states than CON states at each time period and overall (P < .0001). However, the rate of change in THA incidence over the time period was higher in CON states (1.0 per 10,000 per year) compared to non-CON states (0.68 per 10,000 per year) although not statistically significant. Length of stay was higher and a higher percentage of patients received care in high-volume hospitals in CON states (both P < .0001). No meaningful differences in postoperative complications were found. CONCLUSION: CON laws did not appear to have limited the growth in incidence of THA nor improved quality of care or outcomes during the study time period. It does appear that CON laws are associated with increased concentration of THA procedures at higher volume facilities. Given the inherent potential confounding population and geographic factors, additional research is needed to confirm these findings.

BACKGROUND: Pigmented villonodular synovitis (PVNS) is a locally destructive histiocytic proliferation most commonly occurring in the knee. Extensive local joint destruction can indicate the need for a total knee arthroplasty (TKA). The objective of this study is to evaluate PVNS of the knee as a risk factor for complication after TKA. METHODS: Patients who underwent TKA with a diagnosis of PVNS of the knee from 2007 to 2016 were identified in a national private payer insurance database. Complication rates for emergency room visits, readmission, revision, stiffness, infection, and death were calculated and compared to a control population of patients who received TKA for osteoarthritis (OA). RESULTS: Four hundred fifty-three patients were diagnosed with PVNS of the knee and underwent TKA during the time period and compared with a matched control cohort of 1812 patients who underwent TKA for OA. The rate of revision TKA at 2 years, emergency room visits, readmission, and death did not differ between the PVNS group and the control cohort. The PVNS group had stiffness at 1 year compared to the OA group (6.84% vs 4.69%, odds ratio 1.48, P = .023). The infection rate at 2 years was 3.31% in the PVNS group and 1.55% in the OA group (odds ratio 1.73, P = .011). CONCLUSION: The complication rates for TKA in patients with a diagnosis of PVNS of the knee have not been previously demonstrated. These patients have a higher rate of stiffness and infection when compared to a control cohort, so they may have a more complicated postoperative course.

BACKGROUND: Many states in the United States have certificate-of-need (CON) programs designed to restrain health care costs and prevent overutilization of health care resources. The goal of this study was to characterize the associations between CON regulations and total knee arthroplasty (TKA) by comparing states with and without CON programs. METHODS: Publicly available data were used to classify states in to CON or non-CON categories. The 100% Medicare Standard Analytical Files from 2005 through 2014 were then used to compare primary TKA procedure volumes, charges, reimbursements, and distribution of procedures based on facility volumes between the groups. Adverse events such as infection and emergency room visits after TKA were also evaluated. RESULTS: Although CON status was associated with lower per capita utilization of TKA, the annual incidence of TKA appears to have increased over time more rapidly in states with CON laws compared with non-CON states (overall increase of 5.6% vs 2.3%, P < .01). When normalized to the Medicare population, the incidence of TKA increased 2.0% in CON states, whereas it actually decreased 7.2% in states without CON regulations (P = .011). Average reimbursement (and thus Medicare spend) was 5% to 10% lower in non-CON states at all time points (P < .0001). In non-CON states, relatively more TKAs appear to be performed in lower volume hospitals. Examination of adverse events rates did not reveal any strong associations between any adverse outcome and CON status. CONCLUSION: CON programs appear to have influenced the delivery of care for TKA. Although our data suggest that these laws are associated with lower per capita utilization of TKA and the use of higher-volume facilities, we were unable to detect any strong evidence that CON regulations have been associated with improved quality of care or have limited growth in the utilization of this procedure over time. Confounding population and geographic factors may influence these findings and further study is needed to determine whether or not these programs have served their purpose and should be retained.

Ramp lesions of the medial meniscus are underdiagnosed because of difficulty in visualizing via magnetic resonance imaging and during arthroscopy. They most often occur simultaneously with anterior cruciate ligament (ACL) injury but may also be associated with posterior plateau contusions, steeper medial tibial plateau slope, and excess varus alignment. Upwards of 24% of ACL reconstructions have concomitant ramp lesions. Failure to repair the ramp lesion is associated with increased rotational laxity, tibial translocation, persistent pivot shift, and poorer outcomes after ACL reconstruction. The purpose of this article is to describe an all-suture anchor-based repair of a meniscal ramp lesion, which confers several advantages over traditional repair techniques.
RESUMO
Anterior cruciate ligament (ACL) rupture rates remain high; the incidence of isolated ACL ruptures is 68.6 per 100,000. This Technical Note introduces a technique for ACL reconstruction (ACLR) using a bone-tendon-bone (BTB) allograft augmented with BioBrace, a biocomposite scaffold. The BioBrace scaffold is sutured onto the BTB allograft to reinforce the ligament and accelerate healing. Graft preparation with BioBrace, ACLR, and graft passage is described. This technique aims to reduce re-rupture risk, enhance graft healing, and improve patient-reported outcomes. BioBrace offers advantages over other augmentation approaches and synthetic materials, providing improved remodeling, biologic integration, and increased mechanical strength. Feasibility and efficacy have been demonstrated in animal models and human applications. This technique presents a promising approach to enhance ACLR outcomes.
RESUMO
Introduction: There have been several described imaging findings that correlate with anterior cruciate ligament (ACL) injuries. The investigators in this study observed a higher frequency of posterior translation of the lateral meniscus beyond the posterior border of the tibial plateau in patients with ACL tears. The purpose of this study was to assess the frequency and degree of posterior lateral meniscal overhang (LMO) of the lateral meniscus in patients with ACL tears compared to uninjured controls. Materials and methods: Magnetic resonance imaging (MRI) was analyzed in 117 knees with ACL tears and compared to a control group of 89 knees without injury. Lateral meniscus diameter, LMO, knee flexion angle, and lateral tibial plateau diameter were measured and compared between the two groups. Exclusion criteria included displaced and macerated lateral meniscus tears, multi-ligamentous knee injuries, and periarticular fractures. Difference in mean lateral meniscal overhang between ACL injured and control groups was tested using a paired T-test (alpha = 0.01). Assumptions for normality and variance were tested prior to analysis. Results: In patients with ACL tears, average LMO was significantly greater compared to the control group (0.95 mm vs. 0.08 mm; p < 0.001). Additionally, measurable LMO was found in 42.7 % of patients with ACL tears compared to 4.5 % uninjured knees (p < 0.001). Conclusion: Patients with ACL injury show higher incidence of LMO compared to uninjured controls. Future studies are necessary to better understand its clinical significance.
RESUMO
Background: The posterior oblique ligament (POL) is the largest structure of the posteromedial knee that is at risk of injury in conjunction with the medial collateral ligament (MCL). Its quantitative anatomy, biomechanical strength, and radiographic location have not been assessed in a single investigation. Purpose: To evaluate the 3-dimensional and radiographic anatomy of the posteromedial knee and the biomechanical strength of the POL. Study Design: Descriptive laboratory study. Methods: Ten nonpaired fresh-frozen cadaveric knees were dissected and medial structures were elevated off bone, leaving the POL. The anatomic locations of the related structures were recorded with a 3-dimensional coordinate measuring machine. Anteroposterior and lateral radiographs were taken with radiopaque pins inserted into the pertinent landmarks, and the distances between the collected structures were calculated. Each knee was then mounted to a dynamic tensile testing machine, and pull-to-failure testing was performed to record the ultimate tensile strength, stiffness, and failure mechanism. Results: The POL femoral attachment was a mean of 15.4 mm (95% CI, 13.9-16.8 mm) posterior and 6.6 mm (95% CI, 4.4-8.8 mm) proximal to the medial epicondyle. The tibial POL attachment center was a mean of 21.4 mm (95% CI, 18.1-24.6 mm) posterior and 2.2 mm (95% CI, 0.8-3.6 mm) distal to the center of the deep MCL tibial attachment and a mean of 28.6 mm (95% CI, 24.4-32.8 mm) posterior and 41.9 mm (95% CI, 36.8-47.0 mm) proximal to the center of the superficial MCL tibial attachment. On lateral radiographs, the femoral POL was a mean of 17.56 mm (95% CI, 14.83-21.95 mm) distal to the adductor tubercle and 17.32 mm (95% CI, 14.6-21.7 mm) posterosuperior to the medial epicondyle. On the tibial side, the center of the POL attachment was a mean of 4.97 mm (95% CI, 3.85-6.79 mm) distal to the joint line on anteroposterior radiographs and 6.34 mm (95% CI, 5.01-8.48 mm) distal to the tibial joint line on lateral radiographs, at the far posterior tibial aspect. The biomechanical pull-to-failure demonstrated a mean ultimate tensile strength of 225.2 ± 71.0 N and a mean stiffness of 32.2 ± 13.1 N. Conclusion: The anatomic and radiographic locations of the POL and its biomechanical properties were successfully recorded. Clinical Relevance: This information is useful to better understand POL anatomy and biomechanical properties as well as to clinically address an injury with repair or reconstruction.
RESUMO
Meniscal tears are a common musculoskeletal pathology in the United States, affecting 61 in every 100,000 people. Surgical repair is indicated for certain tear patterns to reduce the risk of joint degeneration, normalize contact forces in the knee, and help restore normal knee kinematics. However, radial meniscus tear repairs fail to completely heal 38% of the time due to tear characteristics, biology, surgical technique, and inadequate rehabilitation. Recent efforts have incorporated biological augmentation to enhance the healing potential of the meniscus. The BioBrace is a biocomposite scaffold designed to mechanically reinforce tissue and biologically enhance healing. The purpose of this article is to describe an all-inside, meniscal radial tear repair augmented with BioBrace.
RESUMO
Anterior cruciate ligament (ACL) reconstruction augmentation continues to be widely studied. Both biologic and synthetic augments have been employed to enhance ACL healing and provide early protection. The BioBrace is a biocomposite scaffold that both mechanically reinforces the graft while biologically enhancing graft healing. The purpose of this article is to describe augmentation of an ACL reconstruction with BioBrace.
RESUMO
Introduction: To evaluate the impact various levels of irradiation have on bone-patellar tendon-bone (BTB) allograft load-to-failure. Materials and methods: Pubmed, Google Scholar and Embase were searched for studies reporting load-to-failure measurements of BTB allografts following gamma or eBeam irradiation. All systematic reviews, editorials, as well as studies that utilized animal models and/or other graft sources (achilles, hamstring, quadriceps) were excluded. Meta-analysis was performed to compare the impact of low dose (19 ≤ kGy), intermediate (20-49 kGy) and high dose (>50 kGy) gamma and eBeam radiation on load-to-failure. Results: Twelve studies, containing a total of 429 BTB allografts (159 controls, 270 irradiated), were identified. Load-to-failure of BTB allograft was significantly decreased at intermediate (20-49 kGy) doses of radiation, while low (≤19 kGy) and high (>50 kGy) doses did not significantly change load-to-failure. Conclusions: Intermediate doses of radiation may negatively impact the biomechanical integrity of BTB allograft in vitro. Future studies are required to examine clinical outcomes at varying irradiation levels.
