Return to Cycling After Total Joint Arthroplasty.

BACKGROUND: As total joint arthroplasty (TJA) candidates become younger, patients' expectations continue to expand. We surveyed our patient population to determine rates of return to cycling after TJA so that we could provide more accurate counseling on performance and safety. METHODS: At our single institution, an online survey was generated and sent out to patients who had at least 3 months of follow-up. Patients were split into 4 categories based on surgery type: single total hip arthroplasty (THA), single total knee arthroplasty (TKA), multiple TJA, and revision TJA. RESULTS: A total of 1,029 surveys fit the inclusion criteria. The average age of the patient population was 69 years, with an average of 4.08 years from their time of most recent TJA surgery (maximum follow-up of 18.61 years). Nearly all those who were able to bike prior to surgery were able to return to cycling, with only 6% not being able to do so. There were 41.8% who returned to cycling less than 3 months after surgery. Most cyclists were able to return to their previous level. Patients who had a revision TJA had significantly lower rates of returning to cycling in comparison to single TKA, single THA, and multi-TJA (37.3%, 60.3%, 61.9%, and 60.3%, respectively, P < .005). Patients who never returned to cycling had higher revision rates in comparison to those who were able to get back on a bike (14.4 versus 9.2%, P = .01). CONCLUSIONS: A large proportion of patients who had prior cycling experience were able to return to bike riding within 3 to 6 months after TJA. Individuals who had revision TJA had lower rates of return to cycling in comparison to single TKA, single THA, and multi-TJA. Returning to cycling did not result in higher rates of revision.

Perioperative Sleep Quality Disturbances in Total Joint Arthroplasty is Multifactorial.

BACKGROUND: Sleep quality following arthroplasty procedures is important for patient recovery and satisfaction, but remains poorly understood. The purpose of this study was to report risk factors for sleep disturbances in the perioperative period in patients undergoing primary total joint arthroplasty procedures. METHODS: Sleep surveys were prospectively collected on 751 consecutive patients undergoing total joint arthroplasty at our institution between June 2019 and February 2021 at their preoperative and postoperative visits (2 and 6 weeks). Data were collected on patient demographics, opioid use (preoperatively and postoperatively) as well as tobacco and alcohol use, and specific medical diagnosis that may influence sleep patterns (ie, depression). Statistical analyses were performed using the Student's t-tests and 1-way analysis of variances. RESULTS: For both total hip and total knee patients, worse sleep patterns preoperatively were found in patients who used opioids prior to surgery (P < .001), were current smokers (P < .001), and were aged less than 65 years (P < .001). Postoperative persistent opioid use (more than 3 months) was seen in patients who had worse reported sleep quality preoperatively (P < .001). In comparison to total hip arthroplasty, patients who underwent total knee arthroplasty were more likely to report less sleep in the postoperative period. Patients who were current smokers (compared to nonsmokers or previous smokers) (P = .014) had worse sleep quality at all time points that persisted at 6 weeks, although these differences were seen more in total hip patients than in total knee patients (P = .006 versus P = .059). CONCLUSIONS: Sleep quality disturbances around the time of surgery appear to be multifactorial. LEVEL OF EVIDENCE: Therapeutic Level III.

Management Principles of Massive Acetabular Bone Loss in Revision Total Hip Arthroplasty A Review of the Literature.

The management of acetabular bone loss during revision arthroplasty is a challenging problem. Not only are there a wide variety of potential defects, but the location of these defects can also drastically change the hip center of rotation, stability, and biomechanics. First, the assessment of the severity and location of bone loss preoperatively is highlighted as it is imperative to evaluate the acetabular bone stock remaining. It is especially important to determine how to identify a pelvic discontinuity. Various classification systems are discussed to help surgeons adequately assess and evaluate these defects. There are also numerous implants and treatment strategies available to manage the problem, all of which are determined by that preoperative assessment and classification. We review the history of managing these defects and how management has evolved into modern designs, including but not limited to structural allograft, distraction arthroplasty, jumbo cups, metal augments, cup-cages, and custom triflanges. This review then describes the up-to-date clinical results of these various techniques, highlighting the surgical execution needed to obtain a successful result. By describing the preoperative assessment, the acetabular defect classifications, and proposed evidence-based treatment algorithms, we hope that this review will enhance the understanding of these challenging reconstructions in the setting of acetabular bone defects.

Males Achieve Similar Success at Two Years Following Hip Arthroscopy Irrespective of Age.

PURPOSE: Previous research has demonstrated that there is a statistically significant relationship between hip arthroscopy outcomes and age. The purpose of this research was to investigate the link, if any, between hip arthroscopy outcomes and intraoperative pathology as well as with both patient age and sex. METHODS: All male patients 14 years of age or older who underwent primary hip arthroscopy for femoroacetabular impingement (FAI) and who had a 2-year patient-reported outcome scores were analyzed. These patients were separated into three age-based cohorts (< 30 years old, 30 to 45 years old, and > 45 years old). These cohorts were then analyzed and compared with respect to patient demographic information, intraoperative pathology, and functional outcome scores for statistical significance, set at p < 0.05. RESULTS: At 2-year follow-up, there was a significant difference seen between the modified Harris Hip scores (mHHS) of the < 30 years old and > 45 years old cohorts with a mean difference of 10.2 (92.05 ± 10.3 and 81.89 ± 16.7, p = 0.044). The results of an ANOVA comparing 2-year non-arthritic hip scores (NAHS) were not statistically significant (p = 0.196). At 2-year follow up, the NAHS scores were 92.18 ± 10.3, 87.76 ± 15.6, and 84.63 ± 15.9 for the < 30 years old, 30 to 45 years old, and > 45 years old cohorts, respectively. When analyzing cohorts for rates of achieving a minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS), however, there were no statistically significant differences between groups. CONCLUSIONS: The results of this study suggest that males of all ages have generally good and similar outcomes following hip arthroscopy for FAI as determined by their similar rates of achieving both MCID and PASS.

Clavicle Nonunion RepairWhat Can Patients Expect?

BACKGROUND: The purpose of this study was to compare the long-term functional status of patients treated surgically for a clavicular nonunion using patients treated either op-eratively or non-operatively for an acute clavicle fracture as a comparison group. METHODS: Twenty consecutive patients treated by a single surgeon for a clavicle fracture nonunion were identified. For comparison of outcomes, acute clavicle fractures were identified from an electronic medical record (EMR) query of the same orthopedic surgeon. Ninety acute clavicle fracture patients were identified and 27 (30%) patients were available for long-term follow-up. Clavicular nonunions were compared to acute clavicle fracture patients in a univariate analysis then a multivariate analysis to analyze clavicle nonunion patients against operative and non-operative acute clavicle fracture patients. The main outcome measures were time to bony union, postoperative complications, visual analog scale (VAS) pain scores, and Short Musculoskeletal Functional Assessment (SMFA) scores at long-term follow-up. RESULTS: There was no difference in time to healing or functional outcomes as assessed by SMFA and VAS pain scores between clavicle nonunion and acute fracture patients. Postoperative complications also did not differ between the groups. CONCLUSIONS: Patients who are treated surgically for clavicular nonunions ultimately regain a similar functional status as patients who are treated either operatively or non-operatively for an acute clavicle fracture and heal acutely.

Factors Associated With Orthopaedic Resident Burnout: A Pilot Study.

INTRODUCTION: Burnout is an occupational hazard for physicians at all stages of training and medical practice. The purpose of the current study was to determine whether residency factors, with the use of an activity monitor, including the amount of exercise, have any impact on burnout among orthopaedic surgery residents in varying years of training. METHODS: Orthopaedic residents at a single institution were recruited immediately before beginning a new clinical rotation and followed for four weeks. On enrollment, the participants were given a wrist-worn activity monitor (Fitbit Flex) and instructed on its use for tracking physical activity. REDCap was used to collect burnout levels (as assessed by using the Maslach Burnout Inventory and the Patient Health Questionnaire-9), which were completed a total of five times, once at enrollment and weekly during the study period. RESULTS: Twenty-seven residents were enrolled, including 13 junior residents (interns and second years) and 14 senior residents (third, fourth, and fifth years). Seven residents were on fracture rotations, whereas 20 were not. As measured by using the Maslach Burnout Inventory, juniors were more emotionally exhausted (P = 0.01) and depersonalized (P = 0.027). No difference in the objective physical activity data as measured by using the Fitbit Flex and no difference in the self-reported hours of sleep were observed. Residents on orthopaedic trauma rotations also reported significantly higher rates of emotional exhaustion and depersonalization (P < 0.001) than other residents and were more physically active on average (P < 0.030). DISCUSSION: Although depersonalization and depression are common symptoms seen among orthopaedic surgery residents, this study demonstrated that quality of life improves markedly as they progress through their residency training. Residents on orthopedic trauma rotations have greater levels of emotional exhaustion and depersonalization. This pilot study suggests that burnout prevention programs should begin at the start of training to provide residents with strategies to combat and then reinforced while on orthopaedic trauma rotations. LEVEL OF EVIDENCE: Level III Diagnostic Study.

Cemented versus Cementless Stems in Revision Total Knee Arthroplasty.

Successful arthroplasty of the knee requires a stable foundation for implant placement, adequate mechanical alignment, and durable fixation. In the revision setting, the later may be difficult to obtain, especially in the setting of significant bone loss. While augments, cones, and sleeves have greatly enhanced the modern knee surgeon's ability to gain fixation in metaphyseal bone, stems continue to be a cornerstone tool in revision arthroplasty to bypass deficient or damaged bone surfaces to enhance structural stability of a revision construct. When placing a revision construct, there remains two options to assist with fixation, either fully cementing the entire implant or using a "hybrid" system, which combines an uncemented press-fit diaphyseal stem with cement in both the metaphysis and metaphysis-diaphysis junction of the keel. In this review, we discuss the history of these two techniques, evaluate the theoretical benefits and pitfalls, and assess the best evidence supporting each in the literature. To conclude, we will examine future directions and questions needed to better elucidate the best treatment options in a variety of revision scenarios.

Patient Reported Pain After Successful Nonunion Surgery: Can We Completely Eliminate It?

OBJECTIVES: To investigate what factors are associated with continued long-term pain after fracture nonunion surgery. DESIGN: Prospective cohort study. SETTING: Single Academic Institution. PATIENTS/PARTICIPANTS: Three hundred forty-one patients surgically treated for fracture nonunion were prospectively followed. Demographics, radiographic evaluations, VAS pain scores, and short musculoskeletal functional assessment (SMFA) scores were collected at routine intervals. Only patients who had a minimum of 1-year follow-up and complete healing were included this analysis. Patients were divided into a high-pain and low-pain cohort for comparison. Inclusion criteria for the high-pain cohort were defined as any patient who reported a pain score greater than one standard deviation above the mean. MAIN OUTCOME MEASURES: Long-term VAS pain scores and factors contributing to increased patient-reported long-term VAS pain scores. RESULTS: Two hundred seventy patients met criteria and were included in this analysis, with 223 patients (82.6%) in the low-pain cohort and 47 patients (17.4%) in the high-pain cohort. The mean long-term pain score was 7.47 ± 1.2 in the high-pain group and 1.78 ± 1.9 in the low-pain group. Within the high-pain cohort, 55.6% of patients reported a net increase in pain from baseline to long-term follow-up compared with 10.5% in the low-pain cohort (P < 0.0005). High baseline pain score (P = 0.003), increased Charlson comorbidity index (CCI) (P = 0.008), lower income level (P = 0.014), and current smoking status (P = 0.033) were found to be significantly more prevalent in the high-pain cohort. CONCLUSIONS: Patients with higher baseline pain scores, elevated Charlson comorbidity index, lower income level or history of smoking are at an increased risk of reporting significant and potentially debilitating long-term pain after nonunion surgery. Although patients may expect complete relieve of pain, orthopaedic surgeons must inform patients of the possibility of experiencing pain 1 year or more postoperatively.

Fracture Severity Based on Classification Does Not Predict Outcome Following Proximal Humerus Fracture.

This study was conducted to determine whether proximal humerus fracture patterns as defined by the Orthopaedic Trauma Association (AO/OTA) classification and the Neer 4-part system predicted functional outcomes for patients treated with open reduction and internal fixation with locked plates and, if so, which system correlated better with outcomes. During a 12-year period, 213 patients with a displaced proximal humerus fracture who underwent surgical treatment with a locking plate at 1 academic institution were prospectively followed. All patients were treated in a similar way and were followed by the operating surgeon at routine intervals. Functional outcomes were measured with the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. Of these patients, 164 were available for analysis. Functional outcomes based on DASH scores did not differ significantly by Neer system, AO/OTA classification, or varus/valgus humeral head alignment at more than 12 months postoperatively. However, patients with Neer 4-part fracture and AO/OTA type 11-C fracture had worse shoulder range of motion in terms of forward elevation and external rotation. Time to healing and complication rates also were not significantly different based on either classification system. Fracture classification can predict shoulder range of motion 12 months after surgical fixation, but its use is limited in predicting functional outcome scores, time to healing, and complication rates. Patients who undergo surgical repair of a proximal humerus fracture can expect good functional results independent of the initial injury pattern, but more severe fracture patterns may lead to decreased shoulder range of motion.

Fracture Site Mobility at 6 Weeks After Humeral Shaft Fracture Predicts Nonunion Without Surgery.

OBJECTIVES: To assess the presence of fracture site gross motion on physical examination to predict humeral shaft fracture progression to nonunion in patients managed nonoperatively. DESIGN: Retrospective cohort study. SETTING: Single trauma level 1 institutional center. PATIENTS: Eighty-four consecutive patients undergoing nonoperative treatment of a diaphyseal humeral shaft fracture were identified. The average age of the population was 48.3 years, and 50% of the cohort was men. INTERVENTION: Clinical examination for fracture stability was routinely performed on patients by the treating physicians and documented it in the medical record. Patients were followed until union or surgery for persistent fracture mobility. MAIN OUTCOME MEASUREMENTS: Stability was graded if there was motion at the site (1: motion of any kind and 0: moved as a unit). RESULTS: Seventy-three patients (87%) healed their fracture within our study cohort by 6 months postfracture. Of the remaining 11 patients, after discussion with their treating physicians about the option of surgical intervention, 8 chose to undergo open reduction internal fixation at an average of 8 months, 1 proceeded nonsurgical interventions, and 2 were lost of follow-up. If the humeral shaft fracture site was mobile at 6 weeks follow-up visit, it identified future fracture nonunion with 82% sensitivity and 99% specificity (only 1 patient with motion at 6 weeks proceeded to fracture union). CONCLUSION: With a high negative predictive value, clinical examination of fracture motion at 6 weeks should be assessed in every patient to determine which patients should obtain closer follow-up for the risk of nonunion progression. Knowledge of gross fracture motion can be used in the shared decision-making model in counseling about early surgical options. LEVEL OF EVIDENCE: Diagnostic Level III.
