BELFAST, NORTHERN IRELAND — Researchers from the United Kingdom have validated and confirmed the reproducibility of the pivot apprehension test, a knee test like the pivot shift test used to assess an unstable knee and the status of a patient’s ACL.

Patients who underwent primary hip arthroscopy experienced greater improvement in patient-reported outcome scores at 2-year follow-up compared with patients who underwent revision arthroscopy, according to recently presented data.

Results from this study indicated patients had iliopsoas atrophy with a 25% decrease in volume and a decrease of 19% in seated hip flexion strength following hip arthroscopy with iliopsoas release. 

Although most patients undergoing hip arthroscopy do not require an ipsilateral total hip arthroplasty, recently published results showed hip arthroscopy failures occur relatively soon following the procedure.

International orthopaedic knee surgeons and researchers are taking a closer, more critical look at the anterolateral soft tissues of the knee and the role the extra-articular knee structures play in the success of ACL reconstructions, which has led to a wide-scale, heated debate. They are focused on one anterolateral extra-articular knee structure in particular because some surgeons doubt the structure even exists, while others have identified it and call it the anterolateral ligament or ALL.

Decreased pelvic incidence may lead to mixed-type femoroacetabular impingement, according to results.

Decreased joint space, increased time from symptom onset to arthroscopy, male gender and larger alpha angles associated with femoroacetabular impingement were linked with grade IV chondral defects in patients undergoing hip arthroscopy, according to results.

Although the use of arthroscopic surgery has become more prominent during the past several years, whether arthroscopic techniques are beneficial for fracture fixation is still debated among arthroscopists and trauma surgeons.

Meniscus posterior horn root tears with associated extrusion have generated considerable interest since their initial description by Pagnani and colleagues. In 2008, Allaire and colleagues demonstrated a medial meniscus posterior horn root avulsion is biomechanically equivalent to a complete meniscectomy due to the abnormally high peak tibiofemoral contact pressures.

Patients who underwent revision hip arthroscopy experienced improved clinical outcome scores for all patient-reported outcomes, high survivorship and high patient satisfaction scores at 2-year minimum follow-up, according to results.
