Abstract:
As the indications and utilization of hip arthroscopy continue to grow, understanding outcomes in unique patient populations is a popular area of research. A specific cohort of interest are those with generalized joint laxity, a group in which instability issues may already be present and of concern for hip arthroscopy. The Beighton score, the standardized scale used to measure joint laxity in patients, presents several issues for its use as a diagnostic indicator, including disagreement on cut-offs, limited focus on lower extremity joints, and questionable validity. Hip arthroscopy has outgrown the single-faceted system, with controversial evidence to characterize this complex group of patients.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
