“…[3, 33] There is also an increased risk for endstage OA leading to joint replacement in the hip (or knee) contralateral to that of a replaced hip (or knee). [34, 35] Shakoor et al [18] extended these observations to include a greater risk of subsequent replacement of a "non-cognate" joint in the lower extremity contralateral to a replaced joint (e.g. a knee contralateral to a replaced hip).…”

Purpose to determine if asymmetry between hips in pain or radiographic osteoarthritis (RHOA) is associated with worse pain and joint space narrowing (JSN) at baseline and longitudinally in knees contralateral to more affected hips. Methods We studied 279 participants in the Osteoarthritis Initiative with baseline asymmetry between hips in pain and 483 with asymmetry in RHOA none of whom had a hip replacement for ≥4 years after baseline. RHOA assessed from pelvis radiographs was categorized as none, possible or definite and hip pain on most days of a month in the past year as present/absent. Knee pain (WOMAC scale) and JSN (fixed flexion radiographs) were categorized as none, mild and moderate-severe. We compared knees contralateral and ipsilateral to more affected hips on baseline knee pain and JSN using clustered multinomial regression and on change in knee pain and JSN over 4–5 years using generalized linear and logistic estimating equations. Results Knees contralateral to painful hips had less baseline pain (“moderate-severe” vs. “none”, relative risk ratio [RRR]: 0.39, 95% CI = 0.27–0.57), but greater baseline JSN (“moderate-severe” vs. “none”, RRR: 1.62, 95% CI = 1.09–2.38) and greater worsening of pain during follow-up (p = 0.001). Knees contralateral to hips with worse RHOA had nonsignificant trends for greater baseline JSN (p = 0.10) and JSN progression (p = 0.17). Conclusion These findings provide limited support for the hypothesis that early asymmetry in hip pain and RHOA is associated with worse pain and structural outcomes in knees contralateral to the more affected hip.

“…However, after THR, the hip and knee on the limb contralateral to a replaced hip joint are at an elevated risk for joint degeneration and joint replacement (TJR) [1][2][3]. It is known that abnormal joint loading is involved in OA progression and possibly initiation [4,5]; therefore it is possible that the elevated risk of contralateral TJR arises because loading patterns during gait are changed after THR in a way that promotes faster joint degeneration.…”

“…In patients with bilateral disease, the chance of subsequent contralateral THA after unilateral THA is anywhere from 16% to 85% [10,12,[19][20][21][22]. Factors related to subsequent joint arthroplasty in the contralateral joint are described as the radiographic grade of the joint [10,21] and patient age [17,21] at index arthroplasty.…”

Background Currently more than 200,000 THAs are performed annually in the United States. In patients with bilateral disease, the chance of subsequent contralateral THA reportedly ranges from 16% to 85%. Factors influencing contralateral THA are not completely understood. Questions/Purposes We therefore determined (1) the 10-year probability free of progression to contralateral THA after index THA, (2) whether demographics differed between those who did and did not ultimately undergo contralateral THA, and (3) whether initial clinical symptoms and/or degree of radiographic osteoarthritis affects progression. Patients and Methods We retrospectively identified 332 patients with minimum 24-month followup and primary osteoarthritis who underwent unilateral THA between 2001 and 2008. There were 150 men and 182 women with a mean age of 61 years (range, 27-93 years) and a mean BMI of 29.6 kg/m 2 (range, 17.6-49.2 kg/m 2 ). We reviewed clinical, radiographic, and demographic data at index THA and last followup and classified patients as low, indeterminate, or high risk of undergoing contralateral THA.Results Seventy-four of the 332 patients (22%) underwent contralateral THA, resulting in an 83% 10-year probability free of progression to the contralateral hip. Low-risk patients had a less than 1% chance of progression, indeterminate-risk patients had a 16% to 24% chance of progression, and high-risk patients had a 97% chance of progression.
