Editorial Commentary: Patients With Lumbar Pathology or Ipsilateral Knee Pathology Improve After Hip Arthroscopy, but Outcomes Are Not as Good as in Patients With Femoroacetabular Impingement Syndrome Without Concomitant Pathology.

Abstract

From the lumbar spine to foot, the joints of the lower extremity are all intimately connected. Their movements are synchronized in a complex biomechanical dance. Pain in one joint tends to affect the joint above and joint below. Understanding the influence of adjacent-joint disease on the hip can help us better counsel patients undergoing hip surgery. Low-back pathology has been shown to negatively influence outcomes after hip arthroscopy. Ipsilateral knee pain appears to do the same. Patients with femoroacetabular impingement syndrome with ipsilateral knee pain should be counseled that their outcomes may not be quite as good as those without knee pain, but they should be able to expect meaningful improvement of their symptoms, both at the hip and at the knee after hip arthroscopy.
