SURGICAL PEARLS: How Can Surgeons Prevent Instability after THA?

    Instability following primary total hip arthroplasty (THA) continues to be the most common cause of revision THAs, frustrating patients and surgeons alike. According to the 2019 annual report of the American Joint Replacement Registry, instability was the primary diagnosis in 19% of THA revision procedures performed between 2012 and 2018. [1]

    Certain patient factors, such as previous hip surgery, female sex, and advanced age, increase the risk of instability. So do certain intraoperative factors, including errors in patient positioning, cup malpositioning, and the surgical approach.

    What can surgeons do to minimize the risk of instability? Raymond H. Kim, MD, from The Steadman Clinic in Vail, Colorado, addressed this issue at last year’s 7th Annual ICJR South Hip & Knee Course, offering his top tips for preventing and managing instability after THA.
