Does Ipsilateral Knee Pain Improve after Hip Arthroplasty?

Abstract

Background Intraarticular hip disease is commonly acknowledged as a cause of ipsilateral knee pain. However, this is based primarily on observational rather than highquality evidence-based studies, and it is unclear whether ipsilateral knee pain improves when hip disease has been treated. Questions/purposes We asked whether (1) hip disease was associated with preoperative ipsilateral knee pain and (2) ipsilateral knee pain would improve after hip arthroplasty. Patients and Methods We retrospectively assessed knee pain in 255 patients who underwent hip arthroplasties between 2006 and 2008. The WOMAC pain score of each joint was the primary outcome measure, which was obtained prospectively before surgery and at 3 months and 1 year postoperatively. Of the 255 patients, 245 (96%) had followup data obtained at 3 months or 1 year. Results Preoperatively, ipsilateral knee pain was observed more frequently than contralateral knee pain (55% versus 18%). Preoperative ipsilateral knee pain scores were worse than contralateral knee pain scores (mean, 80 versus 95). Ipsilateral knee pain improved at 3 months and 1 year. When compared with the scores for contralateral knee pain at 3 months (95) and 1 year (96), there were no differences between knees.

Mid-long-term results of total knee arthroplasty followed by ipsilateral total hip arthroplasty versus total hip arthroplasty subsequent to ipsilateral total knee arthroplasty: A case-control analysis

“…Although biomechanical changes and redistribution of loading of the lower limb were detected after THA or TKA in certain studies [5][6][7][8][9], the in uence of a prior TJA on the subsequent ipsilateral THA or TKA is limited. Consistent with the ndings of the current study, Foucher et al [10] reported no increase in biomechanical loading during gait on the ipsilateral knee after THA.…”

“…This is because studies have shown knee pain to improve after ipsilateral hip arthroplasty. 16 Equip the patient adequately to ensure efficiency of a specialist opinion It is valuable in having the history and examination in the referral letter.…”

Mid-long-term results of total knee arthroplasty followed by ipsilateral total hip arthroplasty versus total hip arthroplasty subsequent to ipsilateral total knee arthroplasty: a case-control analysis

“…Patients with end-stage degenerative or inflammatory arthritis report excellent outcomes after THA or TKA [ 4 ]. However, there is some evidence to suggest loading redistribution and biomechanical changes in the lower limb after THA or TKA [ 5 – 9 ]. Data concerning the influence of prior THA on the ipsilateral knee joint or ipsilateral TKA remain controversial.…”
