Editorial Commentary: Anterior Cruciate Ligament Allograft Is Rarely Indicated But May Be Considered for Older, Low-Physical Demand Patients.

Graft selection for anterior cruciate ligament reconstruction (ACLR) remains controversial. In addition, an increasing number of ACLRs are being performed in an aging population, creating a potential gap in evidence. The goal is to restore functional stability to the knee; minimize the likelihood of graft failure; and provide patient satisfaction, achieved primarily by a patient's ability to return to unrestricted physical activity.

Metatarsophalangeal Arthroplasty in Hallux Rigidus.

First metatarsophalangeal joint (MTPJ) arthroplasty provides hallux rigidus patients with pain relief and preserved motion, offering an alternative to arthrodesis. Recent advancements in implant technology and surgical techniques have broadened treatment options. Although good outcomes have been documented in the literature, concerns persist regarding increased complications, uncertain long-term efficacy, and challenges in managing failed arthroplasties.

Salvage Reconstruction of a 12-cm Tendon Defect Following Chronic Achilles Rerupture-15-Year Follow-Up: A Case Report.

Case: A 39-year-old man with a chronic Achilles rupture status post (1) failed primary repair and (2) secondary xenograft repair with graft rejection, resulting in a 12-cm Achilles tendon defect, which was reconstructed utilizing an Achilles bone block allograft and flexor hallucis longus (FHL) tendon transfer. At 15-year follow-up, the patient reported good functionality and satisfaction with the repair, with positive patient-reported outcome measures. Physical examination revealed excellent strength and range of motion.

Allograft Anterior Cruciate Ligament Reconstruction Fails at a Greater Rate in Patients Younger Than 34 Years.

Purpose: To characterize the secondary anterior cruciate ligament (ACL) injury rates after primary allograft anterior cruciate ligament reconstruction (ACLR) and to identify the age cut-score at which the risk of allograft failure decreases.

Methods: All patients who underwent primary ACLR within a single orthopaedic department between January 2005 and April 2020 were contacted at a minimum of 2 years post-ACLR to complete a survey regarding complications experienced post-surgery, activity level, and perceptions of knee health. Patients were excluded for incidence of previous ACLR (ipsilateral or contralateral) and/or age younger than 14 years.

Cartilage-penetrating hyaluronic acid hydrogel preserves tissue content and reduces chondrocyte catabolism.

Articular cartilage injuries have a limited healing capacity and, due to inflammatory and catabolic activities, often experience progressive degeneration towards osteoarthritis. Current repair techniques generally provide short-term symptomatic relief; however, the regeneration of hyaline cartilage remains elusive, leaving both the repair tissue and surrounding healthy tissue susceptible to long-term wear. Therefore, methods to preserve cartilage following injury, especially from matrix loss and catabolism, are needed to delay, or even prevent, the deteriorative process.

Telemedicine Foot and Ankle Visits in the COVID-19 Era.

Background: The COVID-19 pandemic created a difficult environment to provide musculoskeletal care to patients with foot and ankle pathology given the limitations placed on in-office visits. Telemedicine offered a unique avenue to reach these patients; however, the efficacy of telemedicine visits in patients with foot and ankle pathology is not well studied. We propose a telemedicine protocol that has allowed us to effectively see and treat patients with foot and ankle pathology.

Outcomes and Complications of Open Versus Minimally Invasive Repair of Acute Achilles Tendon Ruptures: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: An acute Achilles tendon rupture is one of the most common sports injuries, affecting 18 per 100,000 persons, and its operative repair has been evolving and increasing in frequency since the mid-1900s. Traditionally, open surgical repair has provided improved functional outcomes, reduced rerupture rates, and a quicker recovery and return to activities at the expense of increased wound complications such as infections and skin necrosis compared with nonoperative management. In 1977, Ma and Griffith introduced the percutaneous approach, and over the following decades, multiple improved techniques, and modifications thereof, have been described with comparable outcomes with open repair.

Purpose: Ankle arthrodesis (AA) is frequently employed in the treatment of end-stage ankle arthritis, which is common following trauma and athletic injuries. While AA remains a popular therapeutic option, little data exists about activity and sporting capacity following AA. The objective of this research was to determine functional outcomes and sporting activity levels in patients following Ankle Arthrodesis.

Surgical Treatment of Talus OCL: Mid- to Long-Term Clinical Outcome With Detailed Analyses of Return to Sport.

Talus osteochondral lesions are a commonly underdiagnosed problem in young athletes. Talus osteochondral lesions surgical algorithm remains controversial. Current metrics suggest that conventional treatment of osteochondral lesions of the talus is promising; yet return to sport is poorly studied.

Feasibility of Rapid Development and Deployment of a Telemedicine Program in a Foot and Ankle Orthopedic Practice.

Background: A lack of access to care is predictably associated with negative outcomes in foot and ankle surgery. Despite recent advances in telecommunication technologies, the field of orthopedics has been slow to adopt these resources in offsetting barriers to care. The COVID-19 pandemic has forced departments to change their clinical approach, lending unprecedented opportunity to better understand how telehealth may bridge this care gap in foot and ankle practices.

Do Not Judge an Ossicle by Its Size: Type 1 Ossicles Associated With Posterior Tibial Tendon Dysfunction.

Introduction: Patients with type II navicular ossicles have traditionally been considered to be symptomatic, whereas patients with type I and III bones are considered asymptomatic without additional relevant imaging findings. The main objective of this study is to investigate the association of type I os naviculare with clinical symptomology and magnetic resonance imaging findings in comparison to types II and III ossicles.

Methods: Three hundred nine subjects with accessory navicular bone types were identified, and their associations with focal navicular pain, pes planus alignment, ossicle or proximal navicular bone marrow edema pattern presence (BMEP), and posterior tibial tendon (PTT) sheath fluid distension were assessed.

Release of the Tibialis Posterior Muscle Osseofascial Sheath Improves Results of Deep Exertional Compartment Syndrome Surgery: A Comparative Analysis and Long-term Results.

Background: Success rates for surgical management of chronic exertional compartment syndrome (CECS) are historically lower with release of the deep posterior compartment compared with isolated anterolateral releases. At our institution, when a deep posterior compartment release is performed, we routinely examine for a separate posterior tibial muscle osseofascial sheath and release it if present.

Purpose: Within the context of this surgical approach, the aim of the current study was to compare long-term patient satisfaction and activity levels in patients who underwent 2-compartment fasciotomy versus a modified 4-compartment fasciotomy for CECS.

Technique Tip: How to Avoid Excessive Distal Tibia Cut During Total Ankle Replacement.

Several total ankle arthroplasty systems rely on an extramedullary cutting guide that must be placed precisely to gauge the amount of distal tibia excised. While each technique guide offers granular instruction to ensure an accurate assessment of the distal tibia bone cut, it is not typically clear whether the Angel Wing should be placed medially or laterally with respect to the ankle and/or the X-ray beam. We found that placing the Angel Wing guide ipsilateral to the X-ray beam leads to added magnification of the guide with respect to the tibia.

Association of Strength Following Achilles Tendon Repair With Return to Same Level of Play in High-Level Athletes.

Background: Rupture of the Achilles tendon is a common injury and the ability to return to the same level of sporting activity after treatment is an important outcome for patients. The objective of the current study was to examine the relationship between ankle strength and the ability to return to previous level of play following operative repair of an Achilles tendon rupture.

Methods: Patients aged 18 to 50 years at a minimum 1 year postoperation from surgical repair of an Achilles tendon returned for a study visit.

Editorial Commentary: Considering Fatigue When Assessing Athletes for Dynamic Knee Valgus: Is This the Next Big Step in Identifying Anterior Cruciate Ligament Injury Risk?

Excessive dynamic knee valgus during jumping is a poor movement strategy that has been well-documented as a risk factor for anterior cruciate ligament injury. Yet, there has been little progress in the translation of findings from high-tech motion capture laboratories to clinically applicable settings. One barrier to widespread use is expensive technology that requires time; therefore, field-based efficient assessment tools that can be used by several types of clinicians are desperately needed.
