Evaluation of Healing Following Open Gluteus Medius Repair With Biointegrative Implant

This is a prospective, single-center study design with enrollment of 15 subjects. The 15 subjects will all undergo standard gluteus medius repair that includes augmentation with the biointegrative implant. This is a small observational study. As such, we expect that the results from 15 subjects will give an adequate understanding of post surgical healing.

A Study to Evaluate Virtual Reality As Adjunct to Anesthesia During Orthopedic Surgery

The purpose of this study is to obtain feedback from patients and orthopedic surgeons who agree to use virtual reality (VR ) as an adjunct to standard of care in orthopedic cases under regional or central neuraxial nerve block. This will serve as a preliminary study for future trials to compare outcomes between VR and standard of care vs standard of care only.

Developing a Decision Instrument to Guide Abdominal-pelvic CT Imaging of Blunt Trauma Patients

Unrecognized abdominal and pelvic injuries can result in catastrophic disability and death. Sporadic reports of "occult" injuries have generated concern, and physicians, fearing that they may miss such an injury, have adopted the practice of obtaining computed tomography on virtually all patients with significant blunt trauma. This practice exposes large numbers patients to dangerous radiation at considerable expense, while detecting injuries in a small minority of cases. Existing data suggest that a limited number of criteria can reliably identify blunt injury victims who have "no risk" of abdominal or pelvic injuries, and hence no need for computed tomography (CT), without misidentifying any injured patient. It is estimated that nationwide implementation of such criteria could result in an annual reduction in radiographic charges of $75 million, and a significant decrease in radiation exposure and radiation induced malignancies. This study seeks to determine whether "low risk" criteria can reliably identify patients who have sustained significant abdominal or pelvic injuries and safely decrease CT imaging of blunt trauma patients. This goal will be accomplished in the following manner: All blunt trauma victims undergoing computed tomography of the abdomen/pelvis in the emergency department will undergo routine clinical evaluations prior to radiographic imaging. Based on these examinations, the presence or absence of specific clinical findings (i.e. abdominal/pelvic/flank pain, abdominal/pelvic/flank tenderness, bruising abrasions, distention, hip pain, hematuria, hypotension, tachycardia, low or falling hematocrit, intoxication, altered sensorium, distracting injury, positive FAST imaging, dangerous mechanism, abnormal x-ray imaging) will be recorded for each patient, as will the presence or absence of abdominal or pelvic injuries. The clinical findings will serve as potential imaging criteria. At the completion of the derivation portion of the study the criteria will be examined to find a subset that predicts injury with high sensitivity, while simultaneously excluding injury, and hence the need for imaging, in the remaining patients. These criteria will then be confirmed in a separate validation phase of the study. The criteria will be considered to be reliable if the lower statistical confidence limit for the measured sensitivity exceeds 98.0%. Potential reductions in CT imaging will be estimated by determining the proportion of "low-risk" patients that do not have significant abdominal or pelvic injuries.

Adductor Endurance Test: Validity and Reliability

Groin and hip injuries are common in team sports-especially soccer, rugby, and ice hockey-and frequently affect male and young athletes. About 14% of all sports injuries involve the groin and hip region, with most related to the adductor muscles. These injuries often increase during congested match periods and may result in athletes missing 1 to 6.9 weeks of training or competition, extending up to 14 weeks when surgery is required. Weakness in the adductor muscles is a key risk factor for groin injuries, and current assessments primarily measure maximal strength using tools such as squeeze tests, sphygmomanometers, or dynamometers. However, muscle endurance-critical because many injuries occur under fatigue-has not been adequately studied, and no validated endurance tests for the hip adductors exist. This study aims to evaluate the validity and reliability of a newly developed hip adductor endurance test for monitoring endurance strength in professional soccer players.

Muscle O2 Saturation and Hemoglobin Levels During Rehabilitation From Arthroscopic Surgery

This study will utilize the Moxy wearable sensor to measure muscle oxygen saturation levels in athletes following lower extremity surgery (ACL or Hip arthroscopy) to evaluate their Return-to-Play. The acquired data will complement current protocols utilized by Dr. Voos and Dr. Salata in this regard and will add quantifiable evidence to enable a robust measurement of the surgical limb versus non-surgical limb.

Psoas Tenotomy Under Ultrasound

The ilio-psoas conflict is a commonly accepted complication after total hip replacement, often linked to a mispositioning of the acetabular prosthetic component that conflicts with the ilio-psoas tendon. To correct these pains, a psoas tenotomy can be proposed. The results proven by the literature are very satisfactory. Psoas tenotomy is performed endoscopically, arthroscopically, or more rarely open. The contribution of echo surgery allows to limit the scar ransom but also to free itself from a complex infrastructure to the operating room including an arthroscopy column and an intraoperative fluoroscopy for a conventional tenotomy, This also saves procedural and installation time. No studies to date have described ultrasound-assisted psoas tenotomy Yhe investigators conducted a cadaveric study of the feasibility of psoas tenotomy under ultrasound that confirms the feasibility of this technique and the safety of the gesture for the surrounding anatomical structures. The objectives of this study are to assess the feasibility, pain and functional outcomes of ultrasound-assisted psoas tenotomy in patients with ilio-psoas conflict after total hip replacement.

Capsula Closure vs. Non-Capsula Closure: Hip Arthroscopy in Danish Patients With Femoroacetabular Impingement (FAI)

The purpose of this study is to investigate whether patients undergoing surgical treatment (hip arthroscopy) of FAI syndrome will positively benefit from capsular closure, in terms of higher scores in validated patient reported outcome measurements, compared to a Group of patients with FAI syndrome where the capsule is left open at the end of the surgical procedure.

SportsPro: Post-Market Clinical Follow Up Study

Retrospective, multi-center, chart review (only to include data that is part of the surgeons' standard practice)

Evaluation of Non-Surgical and Arthroscopic Treatment for Hip Microinstability

Microinstability of the hip joint is an important cause of hip pain and reduced hip function in young and active individuals. Hip microinstability is due to extraphysiologic hip motion and could be secondary to acetabular dysplasia, connective tissue disorder, macrotrauma, microtrauma, iatrogenic- and idiopathic causes. Treatment for hip microinstability is initiated with non-surgical treatment consisting of physiotherapy aimed mainly at stability. If non-surgical treatment fails, surgery with arthroscopic plication of the hip joint capsule is the preferred method. This study evaluates non-surgical and arthroscopic treatment for hip microinstability regarding hip function and adverse events.

MDR - PMCF Study for Taperloc Complete Stems

The objective of this consecutive series PMCF study is to collect data confirming safety, performance, and clinical benefits of the Taperloc Complete stems when used for primary or revision total hip arthroplasty (implants) at 1,3,5,7 and 10-year follow-up\*. Since Taperloc Complete was introduced to the EU in 2010, all available retrospective data will be collected from each patient and a prospective aspect to the study will be necessary to reach the 10-year time point.

Positioning for Hip Arthroscopic Surgery to Reduce Postoperative Numbness

Compared to the knee and shoulder, the hip joint leaves relatively little space to maneuver arthroscopic instruments and camera. To expand the potential space in the hip joint, traction is commonly applied to the operative leg through a perineal post. This is an effective technique to improve the working space for arthroscopy, however it has been associated with complications, including perineal numbness. Traction pads, used alone or with a perineal post, can reduce pressure on the perineal area, thus reducing numbness. The investigators hypothesize that positioning hip arthroscopy patients using a traction pad on a standard traction table with a perineal post will reduce the incidence and duration of postoperative perineal numbness.

Comparison of Methods in Post Operative Hip Arthroscopy Rehabilitation

The investigators plan to investigate the efficacy of blood flow restriction (BFR) therapy in post operative rehabilitation following hip arthroscopy. BFR has shown to be great at helping the recovery process. SAGA is a well-known smart training technology company, and the investigators aim to partner with SAGA to use the BFR cuffs as the intervention method. The BFR cuff will be added to the current SOC for hip scope PT for the intervention group.

Benefit of 3-D Planning in Total Hip Replacement. A Prospective Randomized Study

In this prospective randomized four-armed study the investigators aim to compare wheter 3-D planning, which necessitates preoperative CT acquisition and sophisticated planning together with engineers, results in measurable benefits in terms of objective and subjective outcome values in a collective of patients undergoing primary total hip replacement. Hypothesis: 1. When compared to 2-D planning, 3-D planning of a THR results in better hip reconstruction, better subjective and clinical outcome and better longevity of total hip implants. 2. When compared to a non-anatomical stem, an anatomical stem allows better hip reconstruction, better subjective and clinical outcome and better longevity of total hip implants.
