Background
Cam morphology, a condition where the femoral head is abnormally shaped, is associated with femoroacetabular impingement (FAI) and hip osteoarthritis. The impact of correcting cam deformity on the joint’s long-term health is unclear.
Methods
This study compared three groups of patients with different levels of cam deformity: those with no deformity, those treated surgically, and those untreated, assessing outcomes such as joint survivability and functional improvement after hip arthroscopy.
Key Findings
Correcting the cam deformity through surgery led to better functional outcomes and a lower risk of progressing to total hip replacement (THA) compared to leaving the deformity untreated.
Higher-grade cartilage damage was found in patients with untreated cam deformity.
Conclusions
Treating cam deformity can positively affect the long-term health of the hip joint and reduce the need for a hip replacement, improving functional outcomes for patients.
What Does This Mean for Patients
If you have cam morphology, getting treatment to correct the deformity may help preserve your hip joint, reduce pain, and improve hip function, delaying or even preventing the need for a hip replacement.
