Effect of posture and femoral neck osteochondroplasty on femur-acetabulum clearance in patients with cam-type femoroacetabular impingement.

It is not clear whether femoral neck osteochondroplasty achieves its objective of increasing femoroacetabular clearance. We used an upright open magnetic resonance imaging scanner to image the hip joint in multiple postures to explore the effect of posture and femoral neck osteochondroplasty on femur-acetabulum clearance in patients with cam-type femoroacetabular impingement. We recruited 13 consecutive patients scheduled to undergo arthroscopic femoral neck osteochondroplasty and completed assessments on 10 patients.

Trunk and lower limb biomechanics during stair climbing in people with and without symptomatic femoroacetabular impingement.

Background: Femoroacetabular impingement is a pathomechanical hip condition leading to pain and impaired physical function. It has been shown that those with femoroacetabular impingement exhibit altered gait characteristics during level walking and stair climbing, and decreased muscle force production during isometric muscle contractions. However, no studies to-date have looked at trunk kinematics or muscle activation during dynamic movements such as stair climbing in this patient population.

A Pre-Operative Exercise Intervention Can Be Safely Delivered to People with Femoroacetabular Impingement and Improve Clinical and Biomechanical Outcomes.

This study aimed to investigate the effects of a pre-hip arthroscopy exercise intervention on hip strength, pain, and function in individuals with femoroacetabular impingement (FAI). A total of 20 individuals with FAI completed a 10-week, partially supervised exercise programme; this included three phases of increasing resistance and functionality, consisting of four to six exercises per phase. Hip strength in all six directions; hip pain; function, as measured by the Hip disability and Osteoarthritis Outcome Score (HOOS); and objective physical function, as measured by the Timed Stair Climb test, were determined before and after the intervention.

Myofascial treatment for patients with acetabular labral tears: a single-subject research design study.

Study Design: Single-subject research design using 4 consecutive patients.

Objective: To assess whether treatment using soft tissue therapy (ART or Active Release Technique), stretching, and strengthening of the hip abductors, hip external rotators, and tensor fascia latae muscles reduces pain and improves self-reported hip function in patients with acetabular labral tears who also have posterolateral hip pain of suspected myofascial origin.

Background: Acetabular labral tears cause pain in some but not all patients.

Kinematic and kinetic differences during walking in patients with and without symptomatic femoroacetabular impingement.

Background: Femoroacetabular impingement is a common hip pathology resulting in pain and impaired physical function. However, very little is known about gait differences between those with and without femoroacetabular impingement. Thus, the purpose of this study was to compare three-dimensional gait kinematics and kinetics between those with femoroacetabular impingement and a healthy, pain-free control group.

Patient-reported outcome instruments for femoroacetabular impingement and hip labral pathology: a systematic review of the clinimetric evidence.

Purpose: The purpose of this study is to systematically review the content and clinimetric evidence (rigor of rating scales and indexes for the description of clinical phenomena) of published patient-reported outcome (PRO) instruments used to assess femoroacetabular impingement (FAI) and labral hip pathology.

Methods: We used Medical Subject Heading terms related to FAI and labrum/labral tears to search the Medline, Embase, and Cochrane databases for studies of FAI and labral hip pathology. Studies with hip-related PRO instruments, with any operative intervention except total hip arthroplasty, were included.

Effect of acetabular labral tears, repair and resection on hip cartilage strain: A 7T MR study.

Background: Tears of the acetabular labrum are frequently present in patients with groin pain. While it is clear that the labrum contributes to the surface area articulating with the femoral head, it is not clear whether labral repair yields different load distribution in the hip compared to labral resection.

Purpose: Determine whether labral repair reduces cartilage strain more effectively than labral resection.

Non-purulent low-grade infection as cause of pain following shoulder surgery: preliminary results.

Low-grade infection was systematically searched for in all revision shoulder surgeries by harvesting tissue samples. Ten consecutive patients were identified with a non-purulent low-grade infection of the shoulder. All of these patients suffered from pain and eight were stiff.

Graft tensioning in anterior cruciate ligament reconstruction: a systematic review of randomized controlled trials.

Purpose: The purposes of this study were to (1) perform a systematic review of randomized controlled trials evaluating graft tensioning in anterior cruciate ligament (ACL) reconstruction, and (2) determine the scientific quality of published randomized controlled trials evaluating graft tensioning in ACL reconstruction.

Methods: The search strategy included a computerized literature search, a citation search, and a manual search of key journals and conference proceedings. Eligible studies were randomized controlled trials evaluating the effect of graft tensioning on the outcomes of ACL reconstruction.

Comparison of the subjective shoulder value and the Constant score.

The purpose of this study was to evaluate the subjective shoulder value (SSV) and to compare it with the Constant score (CS). The SSV is defined as a patient's subjective shoulder assessment expressed as a percentage of an entirely normal shoulder, which would score 100%. Patients who underwent operative treatment for rotator cuff repair (n = 247), arthroplasty (n = 83), or stabilization for recurrent anterior instability (n = 111) were included in this study.

Clinical and structural results of open repair of an isolated one-tendon tear of the rotator cuff.

Background: The clinical outcomes of open rotator cuff repair are well established, but the structural results and their effect on clinical outcome are poorly known. We assessed the structural changes in the musculotendinous units after open rotator cuff repair and correlated these findings with the clinical outcome to establish a benchmark for future series.

Methods: Thirty-two consecutive standardized open repairs of a single tendon tear of the rotator cuff were analyzed in twenty-one men and eleven women with an average age of 59.
