Applications Therefore, the risk factors for failure of HA leading to
THA include-
In India, therapeutic arthroscopic hip procedures involve Age over 60 years
femoroacetabular impingement (FAI), joint debridements,
synovectomy, labral trimming and microfractures. [2] Female sex

HA is also used for the diagnosis of ligamentum teres Pre-existing arthritis
problems, management of capsular problems, repair of
articular cartilage and hip washout in septic arthritis. [3] Clinical implication

Knowledge of risk factors can aid in risk stratification
Advantages of arthroscopy over arthroplasty
through appropriate patient selection. [4]
Hip arthroscopy has several advantages when compared to
open surgery; such as- [3] Patients at risk for THA conversion should be counseled
on potential adverse outcomes to allow patient-physician
Minimally invasive engagement during the shared decision-making process.
