A Biomechanical Comparison Of A Subacromial Balloon Spacer, Superior Capsular Reconstruction, And A Rigid Subacromial Spacer In A Massive Irreparable Rotator Cuff Cadaveric Model, Devin Ferguson

Electronic Thesis and Dissertation Repository

Massive irreparable rotator cuff tears are a common cause of pain and disability. Several different treatments exist; however, they are associated with poor clinical outcomes and survivorship in younger patients without glenohumeral arthritis. The purpose of this thesis was to compare the impact of a subacromial balloon spacer, superior capsular reconstruction, and a rigid subacromial implant on the glenohumeral kinematics and mechanical efficiency of a massive rotator cuff deficient shoulder. The results indicate that each surgical state improves the glenohumeral kinematics of a massive irreparable rotator cuff tear. The subacromial implant leads to mild overcorrection of humeral head translation. No …

A Long-Term Follow-Up Of The Stability Study: Multicenter Rct Comparing Anterior Cruciate Ligament Reconstruction With And Without Lateral Extra-Articular Tenodesis In Individuals At High Risk Of Graft Failure, Katelyn M. Inch

Electronic Thesis and Dissertation Repository

One hundred and ninety-six patients at the Fowler Kennedy Sport Medicine Clinic (FKSMC) undergoing anterior cruciate ligament (ACL) reconstruction (ACLR) were randomized as part of the multi-center STABILITY study to receive either an isolated ACLR or ACLR with a lateral extra-articular tenodesis (LET). The STABILITY study followed these patients up to two years postoperative, and a long-term follow-up protocol was initiated afterwards. Eighty-two patients from this center were seen at three, five and seven years postoperative as part of a long-term follow-up. Our primary outcome was a composite outcome of instability and graft failure. Secondary outcomes included patient-reported outcome measures …

The Rotator Cuff Tendon-To-Bone Interface: Maturation, Aging, And 3d Bioprinting For Regeneration, Xiping Jiang

Theses & Dissertations

Rotator cuff tendon injuries often occur at the tendon-to-bone interface (i.e., enthesis) area with a high prevalence for the elderly population. In addition, regeneration of the gradient structure of the enthesis is still a significant clinical challenge. Our studies aim to identify the histological, molecular, and biomechanical alterations of the rotator cuff enthesis with maturation and aging, and develop a novel therapeutic method using three-dimensional (3D) bioprinting technique to regenerate a functional enthesis. Striking variations of the entheses were observed both histologically and biomechanically during the maturation process. The histological features did not show many differences at the insertion site …

Aberrant landing biomechanics increase the risk of anterior cruciate ligament (ACL) injury and are a focus of rehabilitation after ACL reconstruction. The purpose of the present thesis was to develop and evaluate methods of assessing landing mechanics and investigate the effects of different rehabilitation strategies after ACL reconstruction. Three studies were conducted. The first study used a Delphi process to develop the content of a Clinician-Rated Drop Vertical Jump Scale to evaluate jump landing mechanics during rehabilitation after ACL reconstruction. Twenty experts participated in four rounds of questioning, resulting in 92% agreement for knee valgus collapse, lateral trunk lean, insufficient …

Balance Of Adults With Chronic Ankle Instability Following A 6-Week Core Stability Program, Natalie Dickol

Theses and Dissertations

Ankle injuries are one of the most common injuries in the athletic population because of the anatomy of the ankle in conjunction with dynamic activity. During injury, mechanoreceptors are damaged, effecting neuromuscular control. Lack of neuromuscular control puts patients at risk for re-injury. Chronic ankle instability (CAI) has been defined as a condition associated with recurrent sprains and persistent symptoms, including feelings of "giving way," loss of function and limited movement and continuous ankle pain. Patients with CAI are commonly shown to have functional deficits in postural control, such as overcompensating on the uninvolved limb or unable to maintain proper …

Anterior Cruciate Ligament Injury-Induced Alterations In Inflammation And Muscle Physiology, Emily R. Hunt

Theses and Dissertations--Rehabilitation Sciences

Long term weakness and atrophy of the quadriceps muscle are a direct result of anterior cruciate ligament (ACL) injuries and persist for up to 10 years post injury. Muscle atrophy ensues regardless of ligamentous reconstruction surgery, indicating that muscle atrophy following injury is a function of the ligament rupture and not reconstruction surgery. Elucidating the mechanisms underlying quadriceps atrophy following ACL rupture is crucial for developing interventions to restore proper quadriceps size and mitigate weakness thereby allowing for improved patient function. In addition to understanding the specific mechanisms that contribute to quadriceps atrophy following ACL rupture, the timing of atrophic …

Humeral Retroversion, Range Of Motion, And Strength Adaptations In Tennis Players, Daniel Hannah

Electronic Theses and Dissertations

Purpose: This study aimed to develop an understanding of humeral retroversion (HRV) asymmetries in tennis players and its impact on physical and performance characteristics of the shoulder.Participants: Healthy tennis players were categorized into 3 groups: younger juniors (n=11, age=14.5±0.5 years), older juniors (n=12, age=17.1±0.9 years), and collegiate (n=16, age=19.6±1.2 years). Methods: HRV, internal rotation (IR), and external rotation (ER), total arc of motion (TAM), HRV-corrected IR (HRVcIR), and HRV-corrected ER (HRVcER) were measured and calculated bilaterally using a digital inclinometer and ultrasonography.

The Feasibility Of Gathering Patient-Reported Outcome Measures On Individuals With Acute Ankle Sprains In A Busy Clinic Environment, Ryan Reeson

Electronic Thesis and Dissertation Repository

Ankle sprains are the most common sports injury and can lead to long-term deficits. Patient-reported outcome measures (PROMs) may assist clinicians in evaluating the recovery trajectory of patients with ankle sprains. However, before a large-scale study can be performed, it is necessary to determine whether it is feasible to collect PROMs in a busy clinic environment. This study had a narrow recruitment window but the consent rate was 100%. Ten patients at Fowler Kennedy Sport Medicine Clinic were followed for up to six visits. Three PROMs that characterized lower extremity function were measured. The measurement completion rate decreased from 100% …

Biomechanical Testing Of An Exercise For Strengthening The Proximal Femur., Alyssa Osbourne

Electronic Theses and Dissertations

Based on the principles of cutting edge bone remodeling research, a unique therapeutic exercise device was designed specifically to improve bone quality at the most critical location of the proximal femur prone to fracture: the superior-lateral femoral neck where the fracture first initiates during a fall. The exercise/device is intended to work by inducing enough strain in the bone to stimulate the body’s natural bone remodeling mechanisms to increase bone density in the proximal femur and consequently prevent a fracture from arising if a fall to the side does occur.

In order to test the proposed exercise, experiments simulating the …

Optimizing The Rehabilitation Of Elbow Lateral Collateral Ligament Injuries, Ranita Harpreet Kaur Manocha

Electronic Thesis and Dissertation Repository

Elbow lateral collateral ligament (LCL) injuries frequently arise following trauma, and can result in disabling instability. Typically such injuries are managed with immobilization followed by a graduated exercise regime; however there is minimal biomechanical evidence to support current treatment protocols. This investigation examines the in vitro effectiveness of several rehabilitation techniques using a custom elbow motion simulator. It was found that active range of motion is safest in the overhead position (n = 7). Early motion in this position may reduce the incidence of elbow stiffness without compromising ligament healing following LCL injury. Forearm pronation and active motion stabilize …
