Single-leg postural stability deficits following anterior cruciate ligament reconstruction in pediatric and adolescent athletes

The objective of this study was to compare the postural stability of pediatric and adolescent athletes without anterior cruciate ligament injury with those who underwent anterior cruciate reconstruction (ACLR). Postural stability ratings derived from a video-force plate system during the three stances of the modified Balance Error Scoring System were collected from pediatric and adolescent athletes who underwent ACLR (N=24; mean 1.2 years after surgery) and from uninjured controls (N=479). The postural control rating was calculated as the mean of the displacement and variance of the torso and center of pressure data, normalized on a scale from 0 to 100. A higher rating indicates greater postural stability. Participants who underwent ACLR showed lower postural stability ratings during single-leg stance compared with uninjured controls (40.0 vs. 48.7; P=0.037). ACLR is associated with deficits in postural stability.

AbstractPigmented villonodular synovitis (PVNS) is a proliferative disease that develops in the synovium of joints, especially the knee joints. A 52-year-old man visited our hospital with left knee pain, swelling and symptoms of collapse. Twenty-one years earlier, he had undergone anterior cruciate ligament (ACL) reconstruction using an active bioprosthetic composite (ABC) as an artificial ligament. T1 and T2 weighted magnetic resonance imaging of the knee joint showed rupture of the ABC ligament and low signal intensity of hyperplastic synovium. Arthroscopic total synovectomy without ACL reconstruction was performed and t...

ConclusionA 10.7% ipsilateral reoperation rate at an average of 25.9 (SD 24.5) months after ACLR and an overall ACLR revision rate of 3.1% were demonstrated by the analysis. Meniscal pathology was addressed in the majority of subsequent interventions. Age 19 or younger, female gender, Caucasian race, and WC claim were associated with reoperation. Initial isolated ACLR and procedure performed by high-volume surgeon were associated with reduced reoperation.Level of evidenceLevel III.

ConclusionsThe rate of symptomatic complications associated with CP portal placement was 4.7%; however, abnormal MRI or follow-up arthroscopy findings were much higher than clinically symptomatic patients. This study suggests that CP portal placement could provoke anterior knee compartment fibrosis or hypertrophy.Level of evidenceIV.

The purpose of this study was to compare the biomechanical properties of an anterior cruciate ligament (ACL) anatomic repair of a true femoral avulsion to an anatomic ACL reconstruction. It was hypothesized that the ACL repair and ACL reconstruction would have comparable biomechanical behavior when compared to the native knee.

k Chang Anterior cruciate ligament reconstruction (ACLR) frequently results in quadriceps atrophy. The present study investigated the effect of ACLR on the muscle thickness of the different constituent muscles of the quadriceps and circulating biomarkers related to muscle atrophy and hypertrophy. Fourteen subjects underwent anterior cruciate ligament reconstruction following injury. Quadriceps muscle thicknesses were measured using ultrasound, and circulating biomarkers in the blood were measured using enzyme-linked immunosorbent assays (ELISAs) at the preoperative visit (PRE) and at two postoperative visits (PO1, P...
