Bilateral Simultaneous Anterior Cruciate Ligament Injury: A Case Report and National Survey of Orthopedic Surgeon Management Preference

Unilateral anterior cruciate ligament (ACL) tear is a common injury seen by sports medicine orthopedic surgeons. However, a bilateral simultaneous ACL injury is extremely rare and has been reported only three times in the literature. We present a young female skier with simultaneous bilateral ACL tears that were managed with staged ACL reconstruction. We then conducted a nationwide survey (United States) to determine the prevalence of simultaneous bilateral ACL tear and preferred management strategies by sports medicine orthopedic surgeons. Sports medicine fellowship directors were contacted and asked to send an 8-item survey to colleagues (sports medicine fellowship trained surgeons) asking about overall number of ACL reconstructions performed, number of bilateral simultaneous ACL injuries seen and optimal management strategies of such an injury. Out of 43 responses, only 22 (51.2%) surgeons had seen a bilateral simultaneous ACL injury. Of these, 16 (76.2%) preferred staged reconstruction. Graft choice was mixed between autograft and allograft, but a large majority preferred either patellar tendon autograft (58%) or hamstring autograft (41%) were the most common choice. Staged reconstruction is the treatment of choice by surgeons surveyed in our study

Resilience of Patients Undergoing Knee and Shoulder Arthroscopy Procedures

INTRODUCTION: Resilience is a person\u27s capacity to overcome adversity. The purpose was to determine what patient factors correlate with resilience using the Brief Resilience Score. We hypothesize that characteristics of female sex, younger age, Workers\u27 Compensation status, and preoperative opioid use are predictors of a lower preoperative resilience score and that patients with positive psychosocial factors would have higher resilience scores. METHODS: Eight hundred nine patients undergoing knee or shoulder arthroscopy were preoperatively categorized into low, normal, and high-resilience groups. Preoperative patient-reported outcome measures (PROMs) and demographics were assessed. Statistical analyses evaluated differences in demographics and PROMs between resilience groups. RESULTS: Analysis disclosed notable differences between low, normal, and high-resilience groups regarding demographics and PROMs. High resilience was seen in older patients, male patients, and patients with positive psychosocial factors. Low resilience scores were discovered in Workers\u27 Compensation patients and those with a history of preoperative opioid use. No difference in resilience scores was observed between smokers and nonsmokers. DISCUSSION: Preoperative resilience score is associated with age, sex, preoperative opioid use, Workers\u27 Compensation status, and smoking status of patients undergoing knee or shoulder arthroscopy

Preoperative Predictors of Arthroscopic Partial Meniscectomy Outcomes: The APM Index Score

Problem Statement: - Arthroscopic partial meniscectomy (APM) has been shown to be the most common meniscal surgical treatment in the United States - Pre-op risk factors known to contribute to poor outcomes after APM: Symptom duration and radiographic OA at baseline - Factors with no conclusive effect on post-op outcomes: Baseline knee functional score, location of meniscal tear, BMI, activity level, age, sex, and chondral damage on MRI Project AIM: To create an index score using easily available preoperative risk factors such as Kellgren-Lawrence (KL) grade, age, duration of symptoms, BMI, activity level, and preoperative outcome scores to predict the likelihood of favorable outcomes after APM.https://jdc.jefferson.edu/aoa_research_symposium_posters/1003/thumbnail.jp

Patellofemoral pain syndrome in female athletes: A review of diagnoses, etiology and treatment options

Patellofemoral pain syndrome (PFPS) is one of the most common causes of knee pain and is present in females disproportionately more relative to males. PFPS causes tend to be multifactorial in nature and are described in this review. From a review of the current literature, it is clear that there needs to be further research on PFPS in order to better understand the complex etiology of this disorder in both males and females. It is known that females with patellofemoral pain syndrome demonstrate a decrease in abduction, external rotation and extension strength of the affected side compared with healthy patients. Conservative management, including optimizing muscle balance between the vastus medialis and lateralis around the patella along with formal therapy should be the first line of treatment in patients presenting with PFPS. Surgery should be reserved for patients in which all conservative management options have failed. This review aims to guide physicians in accurate clinicaldecision making regarding conservative and surgical treatment options when specifically faced with PFPS in a female athlete. Furthermore, we will discuss the anatomic variants, incidence and prevalence, etiology, diagnosis and treatment of PFPS

Short-term effects of teriparatide versus placebo on bone biomarkers, structure, and fracture healing in women with lower-extremity stress fractures: A pilot study

Aims In this pilot, placebo-controlled study, we evaluated whether brief administration of teriparatide (TPTD) in premenopausal women with lower-extremity stress fractures would increase markers of bone formation in advance of bone resorption, improve bone structure, and hasten fracture healing according to magnetic resonance imaging (MRI). Methods: Premenopausal women with acute lower-extremity stress fractures were randomized to injection of TPTD 20-µg subcutaneous (s.c.) (n = 6) or placebo s.c. (n = 7) for 8 weeks. Biomarkers for bone formation N-terminal propeptide of type I procollagen (P1NP) and osteocalcin (OC) and resorption collagen type-1 cross-linked C-telopeptide (CTX) and collagen type 1 cross-linked N-telopeptide (NTX) were measured at baseline, 4 and 8 weeks. The area between the percent change of P1NP and CTX over study duration is defined as the anabolic window. To assess structural changes, peripheral quantitative computed topography (pQCT) was measured at baseline, 8 and 12 weeks at the unaffected tibia and distal radius. The MRI of the affected bone assessed stress fracture healing at baseline and 8 weeks. Results: After 8 weeks of treatment, bone biomarkers P1NP and OC increased more in the TPTD- versus placebo-treated group (both p ≤ 0.01), resulting in a marked anabolic window (p ≤ 0.05). Results from pQCT demonstrated that TPTD-treated women showed a larger cortical area and thickness compared to placebo at the weight bearing tibial site, while placebo-treated women had a greater total tibia and cortical density. No changes at the radial sites were observed between groups. According to MRI, 83.3% of the TPTD- and 57.1% of the placebo-treated group had improved or healed stress fractures (p = 0.18). Conclusions: In this randomized, pilot study, brief administration of TPTD showed anabolic effects that TPTD may help hasten fracture healing in premenopausal women with lower-extremity stress fractures. Larger prospective studies are warranted to determine the effects of TPTD treatment on stress fracture healing in premenopausal women
