Current concepts in pediatric and adolescent arthroscopy
Arthroscopy continues to grow as a treatment modality for pediatric and adolescent orthopaedic pathologies. In recent years arthroscopic procedures previously reserved for adult patients have become more frequently used in the treatment of younger individuals.
Arthroscopic treatment of osteoarthritis of the knee: are there any evidence-based indications?
Despite the lack of consensus guidelines and randomized control trials, the use of arthroscopy for the treatment of osteoarthritis of the knee has increased over the last decade.
Casting and Splinting Management for Hand Injuries in the In-Season Contact Sport Athlete
Upper extremity injuries are extremely common in contact sports such as football, soccer, and lacrosse. The culture of competitive athletics provides an environment where hand injuries are frequently downplayed in an effort to prevent loss of game time.
Muscle changes in aging: understanding sarcopenia
Muscle physiology in the aging athlete is complex. Sarcopenia, the age-related decrease in lean muscle mass, can alter activity level and affect quality of life.
The diagnosis of meniscus tears: the role of MRI and clinical examination
Magnetic resonance imaging (MRI) and clinical examination are tools commonly used in the diagnosis of meniscus tears.

Hip arthroscopy in children and adolescents
Hip arthroscopy has become an established procedure for certain indications in adults, but experience in children and adolescents has been more limited.
Bilateral, Atraumatic Proximal Tibiofibular Joint Instability Treated With Suspensory Button Fixation
Proximal tibiofibular joint (PTFJ) instability is a rare cause of lateral-sided knee pain. The authors present a case of bilateral, symptomatic PTFJ instability with peroneal nerve dysfunction in an active 16-year-old female athlete.
Shear- and compression-induced chondrocyte transcription requires MAPK activation in cartilage explants
Chondrocytes regulate the composition of cartilage extracellular matrix in response to mechanical signals, but the intracellular pathways involved in mechanotransduction are still being defined.
Open Reduction Internal Fixation of Isolated Chondral Fragments Without Osseous Attachment in the Knee: A Case Series
Isolated chondral fractures of the knee are a rare and challenging problem, typically occurring with an acute traumatic event such as dislocation of the patella or ligamentous injury.
Combined effects of dynamic tissue shear deformation and insulin-like growth factor I on chondrocyte biosynthesis in cartilage explants
Biophysical forces and biochemical factors play crucial roles in the maintenance of the integrity of articular cartilage. In this study, we explored the effect of dynamic tissue shear deformation and insulin-like growth factor I (IGF-I) on matrix synthesis by chondrocytes within native cartilage explants.
Surgical Management of Concomitant Proximal Tibiofibular Instability and Medial Collateral Ligament Tear: A Case Report
Proximal tibiofibular instability is a relatively rare cause of lateral-sided knee pain, and it can be difficult to diagnose.
Glenoid avulsion of the glenohumeral ligaments as a cause of recurrent anterior shoulder instability
Although the Bankart lesion is accepted as the primary pathology responsible for recurrent shoulder instability, recognition of other soft-tissue lesions has improved the surgical treatment for this common problem.
Understanding the Glenoid Avulsion of the Glenohumeral Ligaments as a Cause of Shoulder Instability: Surgical and Postsurgical Management
In adolescents and young adults, instability is a common shoulder pathology with a myriad of coexisting soft tissue and bony lesions.
Catabolic responses of chondrocyte-seeded peptide hydrogel to dynamic compression
This study investigated the role of matrix metalloproteases and aggrecanases during dynamic compression-induced aggrecan catabolism in chondrocyte-seeded self-assembling peptide hydrogel.
A biomechanical comparison of initial fixation strength of 3 different methods of anterior cruciate ligament soft tissue graft tibial fixation: resistance to monotonic and cyclic loading
Tibial fixation of soft tissue grafts continues to be problematic in the early postoperative period after anterior cruciate ligament reconstruction.
Mechanisms and kinetics of glycosaminoglycan release following in vitro cartilage injury
Acute joint injury leads to increased risk for osteoarthritis (OA). Although the mechanisms underlying this progression are unclear, early structural, metabolic, and compositional indicators of OA have been reproduced using in vitro models of cartilage injury.
