“…Prior studies have focused on surgical technique as well as component orientation as the possible causes of squeak [2,11,12,15,16]. Keurentjes et al [9] reported neck length of the prosthetic design was a possible cause of squeak.…”

“…Theoretically, improved range of motion as the result of smaller neck geometry may lead to bony impingement at the extreme range of motion whereby the femur is levering against the pelvis, causing subluxation of the femoral head and edge loading, leading to stripe wear and squeak. Walter et al [15] found wear scars on retrieved articular liners always occurred on the edge of the insert but indicated they were not aware of this as an association between the wear scars and the transient noise, although the onset of the ''squeaking'' was consistent with a 14-month mean time to onset of squeaking encountered clinically. Taylor et al [14], in attempting to establish a potential cause of the squeak phenomenon, produced wear stripes on ceramic bearings in a laboratory setting and determined that under certain conditions, noise could occur during either edge loading or joint simulation.…”

The incidence of hip ''squeak'' associated with ceramic-on-ceramic bearings has been variably reported, ranging from 0.7% to 20.9%. We determined the patients' perception of squeaking in 306 patients (336 hips) in whom ceramic-on-ceramic total hip arthroplasties (THAs) were performed between 1997 and 2005. A questionnaire regarding hip noise was obtained by telephone. With a minimum followup of 2 years (mean, 3.9 years; range, 2-10 years), 290 patients (320 or 95% of the THAs) completed the questionnaire. Patients reported hip noise in 55 of the 320 THAs (17%); noise was perceived as squeak in 32 of the 320 (10%). Most squeaking hips (29 of 32) were pain-free and symptom-free. One patient was unhappy with his squeaking hip without pain. Our data suggest a much higher incidence of squeak as perceived by patients than previously reported.

“…Another possible mechanism is edge loading when the hip is flexed, as with rising from a chair or climbing a high step [10]. Edge loading may occur with subluxation of the bearing by subluxation-relocation motion [11].…”

“…Some authors have theorized impingement can lead to increased rates of osteolysis and loosening [21,25]. Acetabular positioning is particularly important in hard-onhard bearing surfaces where edge loading may result in stripe wear [23] and squeaking [24].…”

“…The type of bearing surface may also alter the ideal orientation of the component. Hard-on-hard bearing surfaces such as ceramic-on-ceramic and metal-on-metal may be more sensitive to edge loading [23]. Therefore, a more horizontal inclination angle with increased anteversion may be advantageous for these types of bearings.…”

Acetabular Orientation: Anterolateral Approach in the Supine Position

The anterolateral approach in the supine position provides excellent visualization of the acetabulum. The main advantage of the approach, a low dislocation rate, has been demonstrated in the literature, while the purported disadvantage of abductor dysfunction has not been clearly delineated in the literature. The technique requires meticulous attention to preservation of the gluteus medius and minimus tendons. Impingement and dislocation are avoided by careful attention to the preparation of acetabulum, critical assessment of the implanted components, and intraoperative trialing. Leg lengths are assessed through direct palpation of the malleoli. Routine use of postoperative hip precautions is not necessary when this approach is utilized. The anterolateral approach in the supine position allows for a reproducible result with a low dislocation rate. Level of Evidence: Level V, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.
