Management of Bone Loss in Revision Total Knee Arthroplasty: An International Consensus Symposium.

The evaluation, classification, and treatment of significant bone loss after total knee arthroplasty (TKA) continue to be a complex and debated topic in revision TKA (rTKA). Despite the introduction of new evidence and innovative technologies aimed at addressing the approach and care of severe bone loss in rTKA, there is no single document that systematically incorporates these newer surgical approaches. Therefore, a comprehensive review of the treatment of severe bone loss in rTKA is necessary.

Outcomes of ACL Reconstruction Utilizing Supercritical CO-Sterilized Allografts.

Background: Allograft tendons are perceived to have a high ACL graft failure rate in primary anterior cruciate ligament (ACL) reconstruction (ACLR). Historical series may be biased by graft processing methods that degrade the biomechanical properties of donor tendons such as irradiation. Supercritical carbon dioxide (SCCO) is a validated method of terminally sterilizing biomaterials at physiological temperatures without irradiation, but in vivo use of SCCO-processed tendon allografts for primary ACLR has not been reported to date.

Objectives: We compared an ultra-minimally invasive ultrasound-guided percutaneous A1 pulley release and a classic open surgery for trigger digit.

Methods: We designed a single-center randomized control trial. All cases had clinical signs of primary grade III trigger digit.

Patient-reported impairment following TKA is reduced when a computationally simulated predicted ideal alignment is achieved.

Purpose: Joint dynamics following Total Knee Arthroplasty (TKA) may influence patient-reported outcome. Simulations allow many knee alignment approaches to a single patient to be considered prior to surgery. The simulated kinematics can be matched to patient-reported outcome to predict kinematic patterns most likely to give the best outcome.

The intervertebral disc during growth: Signal intensity changes on magnetic resonance imaging and their relevance to low back pain.

Life-time prevalence of low back pain (LBP) in children and adolescents varies from 7% to 72%. Disc changes on magnetic resonance imaging (MRI) have been reported in up to 44% of children with earliest observations around pre-puberty. In this longitudinal cohort study, our objective was to determine the natural history of disc changes from childhood to early adulthood, and the possible association of these changes to LBP.

Translation and psychometric validation of the Finnish version of the Patient Scar Assessment Scale for use in patients with burn scars.

Background: The aim of this study was to create a Finnish scar assessment scale by translating and evaluating the psychometric properties of the Patient Scar Assessment Scale (PSAS), a part of the Patient and Observer Scar Assessment Scale (POSAS), with burn patients to enable its use in burn care.

Methods: The translation process followed international guidelines with forward and backward translations and cognitive debriefing with patients. Psychometric validation was performed with adult patients with burns who had been treated at the Helsinki Burn Centre between 2006 and 2017 with skin grafting following the excision of deep second- or third-degree burns.

Ultra-minimally Invasive Sonographically-guided Trigger Digit Release: An External Pilot Study.

Objectives: The most common surgical option for releasing the first annular pulley in trigger digit (TD) is classic open surgery followed by blind percutaneous release. However, they have been related to major complications and incomplete releases, respectively. Intrasheath sonographically-guided first annular pulley release has recently been shown to be safe and effective in every digit.

ISSLS prize in clinical science 2022: accelerated disc degeneration after pubertal growth spurt differentiates adults with low back pain from their asymptomatic peers.

Purpose: In this prospective observational cohort study, the development of lumbar intervertebral discs (LIVD) on magnetic resonance imaging (MRI) was investigated from childhood to adulthood with emphasis on the possible association of disc degeneration (DD) to low back pain (LBP).

Methods: In 2021, 89 subjects who were enrolled in 1994 in a longitudinal study with lumbar spine MRI at ages 8, 11 and 18 were invited to participate in a long-term follow-up comprising a clinical examination, selected patient-reported outcome measures and a lumbar spine MRI. We assessed all MRIs (three lowest LIVDs) with the Pfirrmann summary score, and the ratio of signal intensity of nucleus pulposus to signal intensity of cerebrospinal fluid (SINDL).
