“…However, single AP plane pelvic radiograph is the common method in the clinic to assess leg lengths. Multiple studies have used single AP plane radiographic images to assess how preoperative LLD may impact patient perceived-LLD, functional outcomes, and patient satisfaction postoperatively [ 3 , 34 ]. Additionally, clinical outcome measures were not available, thus prohibiting comparisons between those with and without LLD and subsequent analysis of clinical outcomes.…”

“…Postoperative THA patients may endorse the sensation of patient-perceived leg length differences (LLD). A perceived LLD may refer to anatomical or functional differences secondary to changes in biomechanical forces and the relationship between the pelvis and lumbar spine [ [3] , [4] , [5] , [6] ]. Preoperative LLD has also been associated with postoperative patient-perceived LLD and poor functional outcomes [ 3 , 7 ].…”

“…Another risk factor for inconsistent LLD is a long R-LLD. Adams et al reported that patients who experienced a P-LLD after surgery had a significantly longer R-LLD initially than those who did not [ 19 ]; a long R-LLD is common in patients with DHOs. It may be corrected by pelvic tilt and tension of the soft tissue around the hip joint, resulting in inconsistency with the P-LLD.…”

Background We aimed to examine the inconsistency between radiographic leg length discrepancy (R-LLD) and perceived LLD (P-LLD) in patients with dysplastic hip osteoarthritis and to evaluate the factors that can cause such inconsistency. Methods We conducted a retrospective study on 120 patients. An inconsistent LLD was defined as a condition in which the P-LLD was shorter than the R-LLD by > 5 mm. We compared relevant data on the general characteristics of the patients and the radiological findings between consistent (group E, 92 cases [76.7%]) and inconsistent LLDs (group S, 28 cases [23.3%]). Results The number of patients with a history of hip surgery on the affected side and the Japanese Orthopedic Association classification pain scores were significantly higher in group S than in group E (32.1% vs. 10.8%, respectively; P = 0.015, and 21.7 ± 7.0 vs. 17.5 ± 8.2, respectively; P = 0.036). The pelvic oblique angle and length of the R-LLD were significantly higher in group S than in group E (2.9 ± 2.5° vs. 0.3 ± 2.3°, respectively; P < 0.01, and 17.2 ± 8.9 mm vs. 6.3 ± 8.4 mm, respectively; P < 0.01). Multivariate logistic analysis revealed that the pelvic oblique angle (odds ratio [OR]: 1.80, 95% confidence interval [CI]: 1.28–2.52; P < 0.01) and length of the R-LLD (OR: 2.75, 95% CI: 1.24–6.12; P = 0.013) were independent risk factors of inconsistent LLD. Conclusion The pelvic oblique angle and a long R-LLD were independent risk factors of inconsistent LLD in patients with dysplastic hip osteoarthritis. Therefore, hip surgeons should consider P-LLD rather than R-LLD to understand the need for conservative intervention.

“…Several other complications, including leg-length discrepancy and various perioperative medical complications, were also not addressed 43 . The latter omission is important to note as leglength discrepancy is a leading cause of patient dissatisfaction and litigation following THA [44][45][46][47][48] .…”

Background: The contemporary patient has access to numerous resources on common orthopaedic procedures before ever presenting for a clinical evaluation. Recently, artificial intelligence (AI)-driven chatbots have become mainstream, allowing patients to engage with interfaces that supply convincing, human-like responses to prompts. ChatGPT (OpenAI), a recently developed AI-based chat technology, is one such application that has garnered rapid growth in popularity. Given the likelihood that patients may soon call on this technology for preoperative education, we sought to determine whether ChatGPT could appropriately answer frequently asked questions regarding total hip arthroplasty (THA). Methods: Ten frequently asked questions regarding total hip arthroplasty were posed to the chatbot during a conversation thread, with no follow-up questions or repetition. Each response was analyzed for accuracy with use of an evidence-based approach. Responses were rated as “excellent response not requiring clarification,” “satisfactory requiring minimal clarification,” “satisfactory requiring moderate clarification,” or “unsatisfactory requiring substantial clarification.” Results: Of the responses given by the chatbot, only 1 received an “unsatisfactory” rating; 2 did not require any correction, and the majority required either minimal (4 of 10) or moderate (3 of 10) clarification. Although several responses required nuanced clarification, the chatbot’s responses were generally unbiased and evidence-based, even for controversial topics. Conclusions: The chatbot effectively provided evidence-based responses to questions commonly asked by patients prior to THA. The chatbot presented information in a way that most patients would be able to understand. This resource may serve as a valuable clinical tool for patient education and understanding prior to orthopaedic consultation in the future.
