In non-elite athletes, women are more likely to return to sports after anterior cruciate ligament reconstruction: a retrospective cohort study.

BACKGROUND: The desire to return to sports (RTS) and return to performance at preinjury level (RTSP) is a common motivator for athletes undergoing anterior cruciate ligament (ACL) reconstructive surgery. However, for non-elite athletes little is known about the patient and surgical variables influencing RTS/RTSP. Purpose was to determine which patient or surgical variables had an effect on RTS/RTSP in non-elite athletes. We also analyzed whether patients that RTS and RTSP have more confidence in the knee and less difficulty pivoting. METHODS: A single-centre retrospective cohort study. All patients who had undergone primary hamstring ACL reconstruction within a 5-year period were included. Patients were asked about their pre- and postoperative sports participation using the Tegner Activity Score (TAS) as well as about their RTS/RTSP. Confidence in the knee and difficulty with pivoting were asked about. To determine the potential adverse effect of patient variables at the time of surgery (sex, age, height, weight, TAS preop) and surgical variables (graft diameter, surgical technique, concomitant injury) influencing RTS/RTSP, univariate and multivariate logistic regression analysis were used. RESULTS: 370 ACL reconstructions were included. Average follow-up was 4.6 years (SD 1.4). RTS rate was 65% and RTSP 43%. Median preinjury TAS was 7 (Q1:6, Q3:8)), postoperative 6 (Q1:4, Q3:7). Multivariate analysis showed that women were more likely to RTS (OR 2.40, 1.16-4.97). A lower preinjury TAS (OR 0.80, 0.67-0.95) resulted in higher RTSP levels. None of the surgical variables had a significant influence on RTS or RTSP. Patients who returned to sports or to preinjury-level performance displayed significantly more confidence in the operated knee and less difficulty pivoting than non-returning patients. CONCLUSION: Our study shows that 65% of non-elite athletes with an ACL reconstruction returned to sports, 43% at preinjury level. Women were over twice more likely to RTS than men. Preinjury TAS significantly influences RTSP, with a lower preinjury TAS leading to a higher percentage of RTSP. Patients returning to both scored better in their self-reported confidence in the knee and difficulty pivoting than non-returning patients. LEVEL OF EVIDENCE: Retrospective cohort III.

The value of preoperative diagnostic testing and geriatric assessment in frail institutionalized elderly with a hip fracture; a secondary analysis of the FRAIL-HIP study.

PURPOSE: The aim of this study was to provide a comprehensive overview of (preoperative and geriatric) diagnostic testing, abnormal diagnostic tests and their subsequent interventions, and clinical relevance in frail older adults with a hip fracture. METHODS: Data on clinical consultations, radiological, laboratory, and microbiological diagnostics were extracted from the medical files of all patients included in the FRAIL-HIP study (inclusion criteria: hip fracture, > 70 years, living in a nursing home with malnourishment/cachexia and/or impaired mobility and/or severe co-morbidity). Data were evaluated until hospital discharge in nonoperatively treated patients and until surgery in operatively treated patients. RESULTS: A total of 172 patients (88 nonoperative and 84 operative) were included, of whom 156 (91%) underwent laboratory diagnostics, 126 (73%) chest X-rays, and 23 (13%) CT-scans. In 153/156 (98%) patients at least one abnormal result was found in laboratory diagnostics. In 82/153 (50%) patients this did not result in any additional diagnostics or (pharmacological) intervention. Abnormal test results were mentioned as one of the deciding arguments for operative delay (> 24 h) for 10/84 (12%) patients and as a factor in the decision between nonoperative and operative treatment in 7/172 (4%) patients. CONCLUSION: A large number and variety of diagnostics were performed in this patient population. Abnormal test results in laboratory diagnostics were found for almost all patients and, in majority, appear to have no direct clinical consequences. To prevent unnecessary diagnostics, prospective research is required to evaluate the clinical consequences and added value of the separate elements of preoperative diagnostic testing and geriatric assessment in frail hip fracture patients.

The Quality of Dying in Frail Institutionalized Older Patients After Nonoperative and Operative Management of a Proximal Femoral Fracture: An In-Depth Analysis.

Proximal femoral fractures in frail patients have a poor prognosis. Despite the high mortality, little is known about the quality of dying (QoD) while this is an integral part of palliative care and could influence decision making on nonoperative- (NOM) or operative management (OM). To identify the QoD in frail patients with a proximal femoral fracture. Data from the prospective FRAIL-HIP study, that studied the outcomes of NOM and OM in institutionalized older patients ≥70 years with a limited life expectancy who sustained a proximal femoral fracture, was analyzed. This study included patients who died within the 6-month study period and whose proxies evaluated the QoD. The QoD was evaluated with the Quality of Dying and Death (QODD) questionnaire resulting in an overall score and 4 subcategory scores (Symptom control, Preparation, Connectedness, and Transcendence). In total 52 (64% of NOM) and 21 (53% of OM) of the proxies responded to the QODD. The overall QODD score was 6.8 (P25-P75 5.7-7.7) (intermediate), with 34 (47%) of the proxies rating the QODD 'good to almost perfect'. Significant differences in the QODD scores between groups were not noted (NOM; 7.0 (P25-P75 5.7-7.8) vs OM; 6.6 (P25-P75 6.1-7.2), P = .73). Symptom control was the lowest rated subcategory in both groups. The QoD in frail older nursing home patients with a proximal femoral fracture is good and humane. QODD scores after NOM are at least as good as OM. Improving symptom control would further increase the QoD.

Factors Associated With Nonunion in Arthrodesis of the First Metatarsophalangeal Joint: A Multicenter Retrospective Cohort Study.

BACKGROUND: Arthrodesis of the first metatarsophalangeal joint is the current treatment of choice for symptomatic advanced hallux rigidus and moderate-to-severe hallux valgus. There are different methods to perform arthrodesis, yet no consensus on the best approach. Therefore, this study aimed to determine the effects of preoperative and postoperative hallux valgus angle (HVA), joint preparation and fixation technique, and postoperative immobilization on the incidence of nonunion. METHODS: A retrospective multicenter cohort study was performed that included 794 patients. Univariate and multiple logistic regression was conducted to determine associations between joint preparation, fixation techniques, postoperative immobilization, weightbearing, and pre- and postoperative HVA with nonunion. RESULTS: Nonunion incidence was 15.2%, with 11.1% symptomatic and revised. Joint preparation using hand instruments (OR 3.75, CI 1.90-7.42) and convex/concave reamers (OR 2.80, CI 1.52-5.16) were associated with greater odds of a nonunion compared to planar cuts. Joint fixation with crossed screws was associated with greater odds of nonunion (OR 2.00, CI 1.11-3.42), as was greater preoperative HVA (OR 1.02, CI 1.00-1.03). However, the latter effect disappeared after inclusion of postoperative HVA in the model, with a small association identified between residual postoperative HVA and nonunion (OR 1.04, CI 1.01-1.08). Similarly, we found an association between odds of nonunion and higher body weight (OR 1.02, CI 1.01-1.04) but not of body mass index. CONCLUSION: Based on our results, first metatarsophalangeal joint arthrodesis with planar cuts and fixation with a plate and interfragmentary screw is associated with the lowest odds of resulting in a nonunion. Higher body weight and greater preoperative HVA were associated with slight increase in rates of nonunion. It is crucial to properly correct the hallux valgus deformity during surgery. LEVEL OF EVIDENCE: Level III, retrospective case control study.

The role of patient characteristics and the effects of angiogenic therapies on the microvasculature of the meniscus: A systematic review.

BACKGROUND: Considerable interindividual variation in meniscal microvascularization has been reported. The purpose of this review was to identify which patient characteristics affect meniscal microvascularization and provide a structured overview of angiogenic therapies that influence meniscal neovascularization. METHODS: A systematic literature search was undertaken using PubMed, Embase, Web of Science, Cochrane library and Emcare from inception to November 2021. Studies reporting on (1) Patient characteristics that affect meniscal microvascularization, or (2) Therapies that induce neovascularization in meniscal tissue were included. Studies were graded in quality using the Anatomical Quality Assessment (AQUA) tool. The study was registered with PROSPERO(ID:CRD42021242479). RESULTS: Thirteen studies reported on patient characteristics and eleven on angiogenic therapies. The influence of Age, Degenerative knee, Gender, and Race was reported. Age is the most studied factor. The entire meniscus is vascularized around birth. With increasing age, vascularization decreases from the inner to the peripheral margin. Around 11 years, blood vessels are primarily located in the peripheral third of the menisci. There seems to be a further decrease in vascularization with increasing age in adults, yet conflicting literature exists. Degenerative changes of the knee also seem to influence meniscal vascularization, but evidence is limited. Angiogenic therapies to improve meniscal vascularization have only been studied in preclinical setting. The use of synovial flap transplantation, stem cell therapy, vascular endothelial growth factor, and angiogenin has shown promising results. CONCLUSION: To decrease failure rates of meniscal repair, a better understanding of patient-specific vascular anatomy is essential. Translational clinical research is needed to investigate the clinical value of angiogenic therapies.

Shared decision-making for the treatment of proximal femoral fractures in frail institutionalised older patients: healthcare providers' perceived barriers and facilitators.

INTRODUCTION: Proximal femoral fractures are common in frail institutionalised older patients. No convincing evidence exists regarding the optimal treatment strategy for those with a limited pre-fracture life expectancy, underpinning the importance of shared decision-making (SDM). This study investigated healthcare providers' barriers to and facilitators of the implementation of SDM. METHODS: Dutch healthcare providers completed an adapted version of the Measurement Instrument for Determinants of Innovations questionnaire to identify barriers and facilitators. If ≥20% of participants responded with 'totally disagree/disagree', items were considered barriers and, if ≥80% responded with 'agree/totally agree', items were considered facilitators. RESULTS: A total of 271 healthcare providers participated. Five barriers and 23 facilitators were identified. Barriers included the time required to both prepare for and hold SDM conversations, in addition to the reflective period required to allow patients/relatives to make their final decision, and the number of parties required to ensure optimal SDM. Facilitators were related to patients' values, wishes and satisfaction, the importance of SDM for patients/relatives and the fact that SDM is not considered complex by healthcare providers, is considered to be part of routine care and is believed to be associated with positive patient outcomes. CONCLUSION: Awareness of identified facilitators and barriers is an important step in expanding the use of SDM. Implementation strategies should be aimed at managing time constraints. High-quality evidence on outcomes of non-operative and operative management can enhance implementation of SDM to address current concerns around the outcomes.

Young men are at higher risk of failure after ACL hamstring reconstructions: a retrospective multivariate analysis.

BACKGROUND: Results of ACL reconstruction are influenced by both patient and surgical variables. Until now a significant amount of studies have focused on the influence of surgical technique on primary outcome, often leaving patient variables untouched. This study investigates the combined influence of patient and surgical variables through multivariate analysis. METHODS: Single-center retrospective cohort study. All patients who underwent primary ACL hamstring reconstruction within a 5-year period were included. Patient characteristics (gender, age, height, weight, BMI at time of surgery) and surgical variables (surgical technique, concomitant knee injury, graft diameter, type of femoral and tibial fixation) were collected. Patients were asked about Tegner Activity Scale (TAS), complications and revision surgery. Multivariate logistic regression was used to study risk factors. First graft failure and potential risk factors (patient and surgical) were univariately assessed. Risk factors with a p-value ≤ 0.05 were included in the multivariate model. RESULTS: Six hundred forty-seven primary ACL hamstring reconstructions were included. There were 41 graft failures (failure rate 6.3%). Patient gender, age, height and preoperative TAS had a significant influence on the risk of failure in the univariate analysis. The multivariate analyses showed that age and sex remained significant independent risk factors. Patients with a failed ACL reconstruction were younger (24.3 vs 29.4 years, OR 0.937), with women at a lower risk for failure of their ACL reconstruction (90.2% males vs 9.8% females, female OR 0.123). ACL graft diameter and other surgical variables aren't confounders for graft failure. CONCLUSION: This study shows that patient variables seem to have a larger influence on the failure rate of ACL hamstring reconstructive surgery than surgical variables. Identification of the right patient variables can help us make more informed decisions for our patients and create patient-specific treatment protocols. Young men's higher risk of failure suggests that these patients may benefit from a different reconstruction technique, such as use of a patellar tendon or combined ligament augmentation. LEVEL OF EVIDENCE: Retrospective cohort III.

Evaluation of Quality of Life After Nonoperative or Operative Management of Proximal Femoral Fractures in Frail Institutionalized Patients: The FRAIL-HIP Study.

Importance: Decision-making on management of proximal femoral fractures in frail patients with limited life expectancy is challenging, but surgical overtreatment needs to be prevented. Current literature provides limited insight into the true outcomes of nonoperative management and operative management in this patient population. Objective: To investigate the outcomes of nonoperative management vs operative management of proximal femoral fractures in institutionalized frail older patients with limited life expectancy. Design, Setting, and Participants: This multicenter cohort study was conducted between September 1, 2018, and April 25, 2020, with a 6-month follow-up period at 25 hospitals across the Netherlands. Eligible patients were aged 70 years or older, frail, and institutionalized and sustained a femoral neck or pertrochanteric fracture. The term frail implied at least 1 of the following characteristics was present: malnutrition (body mass index [calculated as weight in kilograms divided by height in meters squared] <18.5) or cachexia, severe comorbidities (American Society of Anesthesiologists physical status class of IV or V), or severe mobility issues (Functional Ambulation Category ≤2). Exposures: Shared decision-making (SDM) followed by nonoperative or operative fracture management. Main Outcomes and Measures: The primary outcome was the EuroQol 5 Dimension 5 Level (EQ-5D) utility score by proxies and caregivers. Secondary outcome measures were QUALIDEM (a dementia-specific quality-of-life instrument for persons with dementia in residential settings) scores, pain level (assessed by the Pain Assessment Checklist for Seniors With Limited Ability to Communicate), adverse events (Clavien-Dindo classification), mortality, treatment satisfaction (numeric rating scale), and quality of dying (Quality of Dying and Death Questionnaire). Results: Of the 172 enrolled patients with proximal femoral fractures (median [25th and 75th percentile] age, 88 [85-92] years; 135 women [78%]), 88 opted for nonoperative management and 84 opted for operative management. The EQ-5D utility scores by proxies and caregivers in the nonoperative management group remained within the set 0.15 noninferiority limit of the operative management group (week 1: 0.17 [95% CI, 0.13-0.29] vs 0.26 [95% CI, 0.11-0.23]; week 2: 0.19 [95% CI, 0.10-0.27] vs 0.28 [95% CI, 0.22-0.35]; and week 4: 0.24 [95% CI, 0.15-0.33] vs 0.34 [95% CI, 0.28-0.41]). Adverse events were less frequent in the nonoperative management group vs the operative management group (67 vs 167). The 30-day mortality rate was 83% (n = 73) in the nonoperative management group and 25% (n = 21) in the operative management group, with 26 proxies and caregivers (51%) in the nonoperative management group rating the quality of dying as good-almost perfect. Treatment satisfaction was high in both groups, with a median numeric rating scale score of 8. Conclusions and Relevance: Results of this study indicated that nonoperative management of proximal femoral fractures (selected through an SDM process) was a viable option for frail institutionalized patients with limited life expectancy, suggesting that surgery should not be a foregone conclusion for this patient population.

Effect of ACL Reconstruction on Range of Tibial Rotation: A Systematic Review of Current Literature and a Recommendation for a Standard Measuring Protocol.

BACKGROUND: Tibial rotation is an important topic in anterior cruciate ligament (ACL) surgery, and many efforts are being made to address rotational stability. The exact role of the ACL in controlling tibial rotation in clinical studies is unknown. PURPOSE: To quantify the effect of ACL reconstruction on the amount of tibial rotation based on the current available literature. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A literature search of the PubMed and EMBASE databases was performed in August 2019. Two independent reviewers reviewed titles and abstracts as well as full-text articles. A total of 2383 studies were screened for eligibility. After screening of titles and abstracts, 178 articles remained for full-text assessment. Ultimately, 13 studies were included for analysis. A quality assessment was performed by means of the RoB 2.0 (revised tool for Risk of Bias in randomized trials) and the ROBINS-I (Risk Of Bias In Non-randomized Studies-of Interventions) tools. RESULTS: According to the studies using computer-assisted surgery that were included in this review, ACL reconstruction resulted in an average reduction in tibial rotation of 17% to 32% compared with preoperatively; whether the range of tibial rotation returned to preinjury levels remained unclear. In the current literature, a gold standard for measuring tibial rotation is lacking. Major differences between the study protocols were found. Several techniques for measuring tibial rotation were used, each with its own limitations. Most studies lacked proper description of accompanying injuries. CONCLUSION: ACL reconstruction reduced the range of tibial rotation by 17% to 32%. Normal values for the range of tibial rotation in patients with ACL deficiency and those who undergo ACL reconstruction could not be provided based on the current available literature owing to a lack of uniform measuring techniques and protocols. Therefore, we advocate uniformity in measuring tibial rotation.

Frail Patients Benefit From Less Invasive Procedures.

PURPOSE: A traumatic periprosthetic fracture (PPF) is a long-term complication of total hip arthroplasty. Treatment options include revision, open reposition and internal fixation (ORIF), and minimally invasive techniques (MITs). To select the optimal surgical procedure, the level of frailty has to be considered, especially in patients with geriatric trauma. The aim of this study is to determine whether a frail patient has a better outcome postoperatively after less invasive treatment. METHODS AND MATERIALS: Sixty-three patients with an PPF were analyzed in this retrospective study. The level of frailty was obtained by the complex fracture frailty index (CFFI). The CFFI combines comorbidities, laboratory tests, physical abilities, social factors, and cognitive functions. Primary outcomes in this study include mortality, minor complications, and 3 major complications (deceased, reoperation or immobility after 1 year). RESULTS: Thirty frail patients had lower survival rates (P = .014) and significantly more major complications with a relative risk of 3.7 (P = .02). In the entire group of 63 patients, there were no significant differences detected in the outcome measures; however, when specified in a subgroup of 30 frail patients according to our CFFI, significant differences were found. Patients treated with MIT had significantly less major and minor complications compared to ORIF and revision. Furthermore, patients treated with ORIF experienced significantly less minor complications than with revision surgery (P = .015). DISCUSSION AND CONCLUSION: This study shows that frail patients can be adequately detected using our frailty score CFFI and have a lower survival rate, regardless the type of surgery. Another finding is that for frail patients, more invasive surgery has a negative influence on the outcome of the treatment. Therefore, it is of great importance to assess and use the patient's level of frailty to determine the surgical procedure for a PPF.

The value of nonoperative versus operative treatment of frail institutionalized elderly patients with a proximal femoral fracture in the shade of life (FRAIL-HIP); protocol for a multicenter observational cohort study.

BACKGROUND: Proximal femoral fractures are strongly associated with morbidity and mortality in elderly patients. Mortality is highest among frail institutionalized elderly with both physical and cognitive comorbidities who consequently have a limited life expectancy. Evidence based guidelines on whether or not to operate on these patients in the case of a proximal femoral fracture are lacking. Practice variation occurs, and it remains unknown if nonoperative treatment would result in at least the same quality of life as operative treatment. This study aims to determine the effect of nonoperative management versus operative management of proximal femoral fractures in a selected group of frail institutionalized elderly on the quality of life, level of pain, rate of complications, time to death, satisfaction of the patient (or proxy) and the caregiver with the management strategy, and health care consumption. METHODS: This is a multicenter, observational cohort study. Frail institutionalized elderly (70 years or older with a body mass index < 18.5, a Functional Ambulation Category of 2 or lower pre-trauma, or an American Society of Anesthesiologists score of 4 or 5), who sustained a proximal femoral fracture are eligible to participate. Patients with a pathological or periprosthetic fractures and known metastatic oncological disease will be excluded. Treatment decision will be reached following a structured shared decision process. The primary outcome is quality of life (Euro-QoL; EQ-5D-5 L). Secondary outcome measures are quality of life measured with the QUALIDEM, pain level (PACSLAC), pain medication use, treatment satisfaction of patient (or proxy) and caregivers, quality of dying (QODD), time to death, and direct medical costs. A cost-utility and cost-effectiveness analysis will be done, using the EQ-5D utility score and QUALIDEM score, respectively. Non-inferiority of nonoperative treatment is assumed with a limit of 0.15 on the EQ-5D score. Data will be acquired at 7, 14, and 30 days and at 3 and 6 months after trauma. DISCUSSION: The results of this study will provide insight into the true value of nonoperative treatment of proximal femoral fractures in frail elderly with a limited life expectancy. The results may be used for updating (inter)national treatment guidelines. TRIAL REGISTRATION: The study is registered at the Netherlands Trial Register (NTR7245; date 10-06-2018).

Case report; the posttraumatic regeneration of the clavicle.

Fractures of the lateral part account for 25% of all the clavicle fractures. In rare cases, especially with late presentation, the highly osteogenic periosteal sleeve will form bone from the distal epiphysis towards the medial part of the clavicle. In patients with trapezius muscle involvement, we suggest excision of the regenerated limb with a subsequent lock-down procedure of the posterior located clavicle in the periosteal sleeve.

Mid-term results of ankle fractures with and without syndesmotic rupture.

BACKGROUNDS: This study investigated the effect of short term removal of syndesmotic screws on the ankle function after 6 years, as there still exists controversy on the duration of screw stabilization. METHODS: Patients with an ankle fracture who received surgery between 1998 and 2004 were reviewed. One group was composed of patients with an ankle fracture needing a syndesmotic repair with screws. The second was composed of operated patients that did not need syndesmotic repair. The primary scoring used was the Olerud-Molander Ankle Score (OMAS). RESULTS: A total of 59 patients were studied with comparable characteristics, with no significant difference on the OMAS after 6 years between the repair group (81.9) and the non-repair group (90.4). On additional clinical scoring groups remained the same. Joint degeneration was seen in both groups (86.7% vs. 55.5%). CONCLUSIONS: Patients with ankle fractures using syndesmotic repair and screw removal after 8 weeks and operated patients without syndesmotic injury have comparable results after 6 years.

[A man with a swollen shoulder]. / Een man met een gezwollen schouder.

A 25-year-old patient presented to the Emergency Department with a swollen left shoulder after an epileptic seizure. Radiography showed a fracture of the humeral head. A CT-scan of the shoulder confirmed the diagnosis of an avulsion fracture of the lesser tuberosity. This is a rare condition and deserves specific attention and surgical treatment to prevent impaired function of the shoulder due to muscle weakness and impingement of the avulsion fragment.

Are there any advantages in using a distal aiming device for tibial nailing? Comparing the Centro Nailing System with the Unreamed Tibia Nail.

INTRODUCTION: The distal locking of an intramedullary tibial nail can be challenging and time consuming when performed freehand. This study was conducted to evaluate if a distal aiming device would reduce surgical time. MATERIALS AND METHODS: A case-controlled study was performed between 2007 and 2009 with 30 patients receiving a reamed tibial nail (Centronail) with the use of a distal aiming device and 30 patients who were treated with an Unreamed Tibia Nail (UTN), with freehand distal locking, in the same period. The primary outcome in this study was operative time. Secondary outcomes were the need for fluoroscopy, time to consolidation and complications. RESULTS: Operation time was longer in the Centronail group compared with the UTN group (126 min vs. 96 min, p=0.000). Use of fluoroscopy for distal locking was needed in half of the cases (n=16) using a distal aiming device. No differences were found regarding time to consolidation, time to removal of the nail and complications. CONCLUSION: The use of an aiming device for distal locking of a tibia nail lengthens operation time rather than reducing it. Fluoroscopy was still needed in about half of the cases. No difference was seen in clinical outcomes. The use of a distal aiming device to lock a tibial nail appears to have no benefit.
