Use of analgesics before and after total joint replacement in working-age Japanese patients with knee and hip osteoarthritis: A retrospective database study

Nozomi Ebata, Takashi Sakai, Hiroyuki Yamamoto, Tetsumi Toyoda, Kanae Togo, Masataka Deie

Summary: This retrospective longitudinal analysis examined the patterns of analgesic use in patients with knee/hip osteoarthritis before and after total joint replacement surgery. The study found that a large proportion of patients required analgesics both before and after surgery, and many continued to require them even three months post-surgery. Pre-operative analgesic use was found to be associated with continued use after surgery.

Clubfoot Emphasis on the Complex and Atypical Subsets

Mitzi L. Williams, Matthew B. Dobbs

Summary: Clubfoot, a common congenital musculoskeletal condition, is best treated using the Ponseti technique. Accurate and thorough neurological examinations are necessary for identifying atypical cases and the need for specific corrective maneuvers. Long-term follow-up is crucial for minimizing progressive deformities, emphasizing the importance of individualized care.

Abnormal gait pattern in downhill hiking is related to muscular deficits of the knee flexors and extensors in active patients with total knee arthroplasty

Judith Bleuel, Igor Komnik, Iris Mittendorfer, Bjoern Michel, Steffen Willwacher

Summary: This study assessed the walking mechanics of patients with total knee arthroplasty during downhill hiking and compared them to a healthy control group. It was found that patients had lower knee flexion angles and weaker muscle strength compared to the controls. The muscle balance between quadriceps and hamstring muscles was related to the persistence of a stiff knee gait pattern after knee arthroplasty.

Time course of surface electromyography during walking of children with spastic cerebral palsy treated with botulinum toxin type A and its rehabilitation implications

Matteo Cioni, Antonino Casabona, Rosario Ferlito, Mariangela Pisasale, Domenico Marco Romeo, Giulia Messina, Maria Stella Valle

Summary: The study aimed to investigate the temporal changes of electromyographic activity in lower limb muscles during walking after injecting botulinum toxin A into the calf muscles of children with spastic cerebral palsy. The results showed that botulinum toxin A had a significant effect on electromyographic activity, with the most noticeable changes occurring between 4 and 8 weeks post-injection and full recovery at 16 weeks. Significant changes in muscle co-contraction were also observed on the treadmill.

An overview of occupational injuries among female orthopaedic surgeons

Anil B. Sedani, Ramakanth R. Yakkanti, Alina Syros, Ronald M. Swonger, Dawn M. Laporte, Amiethab A. Aiyer, Michele R. D'Apuzzo, Victor H. Hernandez

Summary: This study assesses the occupational injuries that affect female orthopaedic surgeons' physical and mental well-being, and compares them to their male counterparts. The results show significant differences in the psychological and emotional domains, with female orthopaedic surgeons reporting higher rates of burnout, social isolation, and seeking professional counseling. The study suggests the need for more resources to help orthopaedic surgeons cope with the stresses of their demanding profession, particularly in reducing work-related stress among female orthopaedic surgeons.

Neuromodulators can promote nerve regeneration and accelerate functional recovery after peripheral nerve injury: A systematic review

Stephanie Choo, Rachel Phillips, James White, Julia A. Nuelle

Summary: This article provides a systematic review on the treatment of peripheral nerve injuries (PNIs) and finds many potential options, including surgical and pharmacological treatments, with reported benefits such as faster nerve regeneration and improved functional recovery. However, most of the research has been conducted in animal models and the safety profile of some agents limits their systemic treatment.

Gait stability and the relationship with energy cost of walking in polio survivors with unilateral plantarflexor weakness

Elza van Duijnhoven, Marit van der Veen, Fieke S. Koopman, Frans Nollet, Sjoerd M. Bruijn, Merel-Anne Brehm

Summary: Gait stability is impaired in polio survivors with plantarflexor weakness, characterized by increased step width and step length variability and lower MoSAP. These factors are related to the elevated energy cost of walking in polio survivors.

Relationships between trunk muscle activation and thoraco-lumbar kinematics in non-specific chronic low back pain subgroups during a forward bending task

Rebecca Hemming, Alister du Rose, Liba Sheeran, Robert van Deursen, Valerie Sparkes

Summary: In a forward bending task, there is a relationship between trunk muscle activation and regional thoracic and lumbar kinematics in NSCLBP subgroups, indicating different motor control strategies adopted by different subgroups when performing bending tasks.

Is a greater degree of constraint really harmful? Clinical biomechanical comparative study between condylar constrained knee and rotating hinge prosthesis

Victor-Estuardo Leon-Roman, David Garcia-Mato, Irene Isabel Lopez-Torres, Javier Vaquero-Martin, Jose Antonio Calvo-Haro, Javier Pascau, Pablo Sanz-Ruiz

Summary: This study compared the tibial rotation between rotating hinge knee prosthesis and constrained condylar knee prosthesis in a clinical setting. The results showed that the postoperative Knee Injury and Osteoarthritis Outcome Score was significantly higher in the rotating hinge knee prosthesis group compared to the constrained condylar knee group, and the degrees of tibial rotation measured by inertial sensors were also significantly higher in the rotating hinge knee prosthesis group.

Increased age and modified fragility index increases risk of short-term complications after anterior cruciate ligament reconstruction surgery

Jack Zhong, Nathan J. Lee, Ajay Padaki, Connor Crutchfield, Christopher S. Ahmad, David Trofa, Sean Lynch

Summary: This study aimed to evaluate if age is associated with the risk of short-term complications after ACL reconstruction. The results showed that older patients had higher fragility index scores, shorter operative times, and lower use of general anesthesia. Older age was an independent risk factor for VTE, while younger age was associated with prolonged surgeries.

Morphometry of sigmoid notch: A novel method of shape assessment for clinical practice

Anil K. Bhat, N. R. Fijad, Ashwath M. Acharya

Summary: The study aims to assess and describe the distal radioulnar joint (DRUJ) anatomy with reference to sigmoid notch shapes using a novel technique. The prevalence of C-shaped sigmoid notch was found to be higher in both cadaveric and CT-based studies, with the C-shaped notch being considered the most stable shape due to its increased depth.

Summary: This study compared the accuracy of three-dimensional (3-D) to two-dimensional (2-D) templating for total hip arthroplasty (THA). The results showed that CT-based 3-D preoperative planning was superior to 2-D planning in terms of accurate sizing and positioning of the implants.

Summary: This study investigates the influence of geometry design on the mechanical strength of antibiotic cement spacers (CS) through finite element analysis and compression load testing. The results show that the femoral neck area experiences the highest stress and the lowest safety factor. The designed CS can withstand repetitive loads and fails at an ultimate load of 4354 N. The fracture analysis reveals different types of fractures at the femoral neck and proximal stem.
