Blood Flow Restriction Training After Patellar Instability (Brains Trial), Benjamin D. Brightwell, Austin V. Stone, Xiaojuan Li, Peter A. Hardy, Katherine L. Thompson, Brian W. Noehren, Cale A. Jacobs

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background

Patellar instability is a common and understudied condition that disproportionally affects athletes and military personnel. The rate of post-traumatic osteoarthritis that develops following a patellar dislocation can be up to 50% of individuals 5–15 years after injury. Conservative treatment is the standard of care for patellar instability however, there are no evidence-informed rehabilitation guidelines in the scientific literature. The purpose of this study is to assess the effectiveness of blood-flow restriction training (BFRT) for patellar instability. Our hypotheses are that this strategy will improve patient-reported outcomes and accelerate restoration of symmetric strength and knee biomechanics necessary to safely return …

Unicompartmental Knee Arthroplasty Is Associated With A Lower Rate Of Periprosthetic Joint Infection Compared To Total Knee Arthroplasty, Cody S. Lee, Edwin P. Su, Michael B. Cross, Alberto V. Carli, David C. Landy, Brian P. Chalmers

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background: Several studies have reported lower perioperative complications with unicompartmental knee arthroplasty (UKA) than with total knee arthroplasty (TKA). However, there is a paucity of data analyzing the incidence of periprosthetic joint infection (PJI) in similar patients undergoing UKA and TKA. As such, we sought to analyze the incidence of UKA and TKA PJI in a large matched population.

Material and Methods: The Mariner data set of the PearlDiver database was queried for all patients undergoing UKA or TKA during 2010-2017. Included patients were required to have at least 2 years of database inclusion after surgery. Patients were then matched …

Development Of A Mind Body Program For Obese Knee Osteoarthritis Patients With Comorbid Depression, Cale A. Jacobs, Ryan A. Mace, Jonathan Greenberg, Paula J. Popok, Mira Reichman, Christian Lattermann, Jessica L. Burris, Eric A. Macklin, Ana-Maria Vranceanu

Orthopaedic Surgery and Sports Medicine Faculty Publications

Knee osteoarthritis (OA) is the most common joint disorder in the U.S. and a leading cause of disability. Depression and obesity are highly comorbid among knee OA patients, and the combination of obesity and depression is associated with decreased physical activity, higher pain and disability, and more rapid cartilage degradation. Depression, obesity and OA exacerbate one another and share a common pathophysiology involving systemic inflammation and pro-inflammatory cytokines, reflecting a complex mind-body interaction. Current treatments for knee OA offer little to no benefit over placebo, and do not emphasize mind-body practices or physical activity to target the underlying pathophysiology. Mind-body …

Optimizing The Double-Row Construct: An Untied Medial Row Demonstrates Equivalent Mean Contact Pressures In A Rotator Cuff Model, Austin V. Stone, T. David Luo, Aman Sharma, Kerry A. Danelson, Michael De Gregorio, Michael T. Freehill

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background: The merits of a double-row rotator cuff repair (RCR) construct are well-established for restoration of the footprint and lateral-row security. The theoretical benefit of leaving the medial row untied is to prevent damage to the rotator cuff by tissue strangulation, and the benefit of suture tape is a more even distribution of force across the repair site. These benefits, to our knowledge, have not been evaluated in the laboratory.

Hypothesis: Leaving the medial row untied and using a suture bridge technique with suture tape will offer more even pressure distribution across the repair site without compromising total contact force. …

Aseptic Loosening Of An Aptis Distal Radioulnar Joint Arthroplasty – Case Report, Karis Bennett, Srinath Kamineni

Orthopaedic Surgery and Sports Medicine Faculty Publications

Dysfunction of the distal radioulnar joint can cause significant pain and instability. The self-stabilizing APTIS distal radioulnar joint prosthesis is used as a solution for severe distal radioulnar joint pathologies. We present a case of a 60-year-old male, who received an APTIS distal radioulnar joint prosthesis which resulted in aseptic loosening within five years of the initial implantation. Infection, incorrect implantation, demographic differences and over-activity were all excluded as the source; therefore, mechanical aseptic loosening was concluded. Ultimately, two surgeries were required to resolve the patient's pain, which resulted in a one-bone forearm once the implant was extracted. The solution …

Results Of A Feasibility Randomized Controlled Trial (Rct) Of The Toolkit For Optimal Recovery (Tor): A Live Video Program To Prevent Chronic Pain In At-Risk Adults With Orthopedic Injuries, Ana-Maria Vranceanu, Cale A. Jacobs, Ann Lin, Jonathan Greenberg, Christopher J. Funes, Mitchel B. Harris, Marilyn M. Heng, Eric A. Macklin, David Ring

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background: Orthopedic injuries are the leading cause of hospital admissions in the USA, and many of these patients transition into chronic pain. Currently, there are no evidence-based interventions targeting prevention of chronic pain in patients with orthopedic injuries. We iteratively developed a four-session intervention “The Toolkit for Optimal Recovery” (TOR) which we plan to subsequently test for efficacy in a phase III hybrid efficacy-effectiveness multi-site clinical trial. In order to prevent methodological weaknesses in the subsequent trial, we conducted a feasibility pilot to evaluate the TOR delivered via secure live video versus usual care (UC) in patients with orthopedic injuries …

Oral Contraceptive Pills Are Not A Risk Factor For Deep Vein Thrombosis Or Pulmonary Embolism After Arthroscopic Shoulder Surgery, Austin V. Stone, Avinesh Agarwalla, Anirudh K. Gowd, Cale A. Jacobs, Jeffrey A Macalena, Bryson P. Lesniak, Nikhil N. Verma, Anthony A. Romeo, Brian Forsythe

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background: Worldwide, more than 100 million women between the ages of 15 and 49 years take oral contraceptive pills (OCPs). OCP use increases the risk of venous thromboembolism (VTE) through its primary drug, ethinylestradiol, which slows liver metabolism, promotes tissue retention, and ultimately favors fibrinolysis inhibition and thrombosis.

Purpose: To evaluate the effects of OCP use on VTE after arthroscopic shoulder surgery.

Study Design: Cohort study; Level of evidence, 3.

Methods: A large national payer database (PearlDiver) was queried for patients undergoing arthroscopic shoulder surgery. The incidence of VTE was evaluated in female patients taking OCPs and those not taking …

Femoroacetabular Impingement As A Complication Of Acetabular Fracture Fixation, David A. Zuelzer, Christopher B. Hayes, Raymond D. Wright, Stephen T. Duncan

Orthopaedic Surgery and Sports Medicine Faculty Publications

Case

We present the case of a thirteen-year-old female who sustained a posterior wall acetabular fracture dislocation. She underwent urgent closed reduction and subsequent uncomplicated open reduction and internal fixation. Post reduction computed tomography demonstrated a concentrically reduced hip joint with no evidence of femoroacetabular impingement (FAI). She subsequently healed her fracture and returned to running activities; however, one year later presented with aching pain in her thigh. Radiographs demonstrated the development of a large osseous prominence on her anterolateral femoral neck consistent with femoroacetabular impingement. Based on these findings she was evaluated by a hip preservation specialist. She subsequently …

Posterior Interosseous Nerve Localization Within The Proximal Forearm - A Patient Normalized Parameter, Srinath Kamineni, Crystal R. Norgren, Evan M. Davidson, Ellora P. Kamineni, Andrew S. Deane

Orthopaedic Surgery and Sports Medicine Faculty Publications

AIM

To provide a "patient-normalized" parameter in the proximal forearm.

METHODS

Sixty-three cadaveric upper extremities from thirty-five cadavers were studied. A muscle splitting approach was utilized to locate the posterior interosseous nerve (PIN) at the point where it emerges from beneath the supinator. The supinator was carefully incised to expose the midpoint length of the nerve as it passes into the forearm while preserving the associated fascial connections, thereby preserving the relationship of the nerve with the muscle. We measured the transepicondylar distance (TED), PIN distance in the forearm's neutral rotation position, pronation position, supination position, and the nerve width. …

Anatomic Femoral And Tibial Tunnel Placement During Anterior Cruciate Ligament Reconstruction: Anteromedial Portal All-Inside And Outside-In Techniques, Jeremy M. Burnham, Chaitu S. Malempati, Aaron Carpiaux, Mary Lloyd Ireland, Darren L. Johnson

Orthopaedic Surgery and Sports Medicine Faculty Publications

Tunnel malposition is one of the most common technical reasons for anterior cruciate ligament reconstruction failure. Small changes in tunnel placement can result in significant differences in outcome. More anatomic placement of the tunnels can lead to greater knee stability and a more accurate reproduction of native knee kinematics. This Technical Note describes 2 tibial tunnel–independent methods to obtain anatomic femoral tunnel placement. The all-inside anteromedial portal technique requires only minimal surgical incisions but allows precise femoral tunnel placement. However, hyperflexion of the knee is required, adequate surgical assistance is necessary, and this technique may be susceptible to graft-tunnel mismatch. …

Technical Considerations In Revision Anterior Cruciate Ligament Reconstruction For Operative Techniques In Orthopaedics, Jeremy M. Burnham, Elmar Herbst, Thierry Pauyo, Thomas Pfeiffer, Darren L. Johnson, Freddie H. Fu, Volker Musahl

Orthopaedic Surgery and Sports Medicine Faculty Publications

As the incidence of anterior cruciate ligament (ACL) reconstruction continues to increase, the rate of revision surgery continues to climb. Revision surgery has inherent challenges that must be addressed to achieve successful results. The cause of the primary ACL reconstruction failure should be determined and careful preoperative planning should be performed to address the cause(s) of failure. Each patient undergoing revision surgery should undergo a thorough history and physical examination, receive full-length alignment radiographs, lateral radiographs, 45° flexion weight-bearing posteroanterior radiographs, and patellofemoral radiographs. The 3-dimensional computed tomography scan should be performed to assess tunnel position and widening. Magnetic resonance …

Early Detection Of Idiopathic Scoliosis In Adolescents, M. Timothry Hresko, Vishwas Talwalkar, Richard Schwend

Orthopaedic Surgery and Sports Medicine Faculty Publications

The early detection of idiopathic scoliosis has been advocated since the 1950s and ’60s, concurrent with the development in the modern era of ambulatory spinal orthoses to treat scoliosis in adolescents. This led to the development of screening programs for specific populations, as evidenced by school screening programs in the United States and public health systems in Europe and Asia. Over time, the value of population screening in terms of optimal health care and economics has been debated in the popular press, by the U.S. Preventive Services Task Force, and by professional societies. Recent studies on the effectiveness of bracing …

Arthroscopic Ulnar Nerve Identification During Posterior Elbow Arthroscopy, Srinath Kamineni, David Anthony Hamilton Jr.

Orthopaedic Surgery and Sports Medicine Faculty Publications

Elbow arthroscopy has increased in popularity in the past 10 years for both diagnostic and therapeutic purposes. A major limiting factor faced by the elbow arthroscopist is the close proximity of the neurovasculature to the working field, with the risk of iatrogenic injury. Many arthroscopic procedures are less extensive than their open equivalents because of an inability to consistently and safely eliminate the risk of neural and vascular injury. Many open procedures in the posterior compartment of the elbow joint are not routinely performed arthroscopically. The primary reason for this restriction in arthroscopic practice is the locality of the posteromedially …
