Special Issue Information

Dear Colleagues,

Hip and knee arthroplasties remain transformative procedures in modern orthopedic surgery, offering patients significant relief from pain and disability caused by degenerative joint diseases and trauma. With the continuous evolution of surgical techniques, implant technologies, and perioperative care, arthroplasty outcomes have improved remarkably, enabling enhanced functionality and prolonged implant longevity.

This Special Issue aims to explore the latest innovations in this dynamic field. From novel surgical techniques and robotics-assisted procedures to clinical advances in implant biomaterials and personalized medicine, this collection of articles aims to highlight breakthroughs redefining patient care. Furthermore, integrating enhanced recovery protocols, predictive analytics, and multidisciplinary strategies for managing complex cases underscores the importance of a holistic approach to treatment.

Contributions will include original research and reviews from leading professionals in orthopedic surgery and related disciplines. By presenting cutting-edge developments and fostering interdisciplinary collaboration, this Special Issue aspires to shape the future of hip and knee arthroplasty, addressing current challenges and emerging opportunities to optimize patient outcomes worldwide.

We invite researchers and clinicians to share their insights, fostering innovation and excellence in joint replacement surgery.

Relationship Among Global Femoral Offset, Leg Lengthening, and Tibiofemoral Rotation After Total Hip Arthroplasty

Abstract
Background/Objectives: Several studies have described the changes in tibiofemoral rotation (TFRA) and patellar tilt angle (PTA) following total hip arthroplasty (THA). However, no studies have applied three-dimensional measurements to evaluate leg lengthening, changes in global femoral offset (GFO) or TFRA, or PTA [...] Read more.
Background/Objectives: Several studies have described the changes in tibiofemoral rotation (TFRA) and patellar tilt angle (PTA) following total hip arthroplasty (THA). However, no studies have applied three-dimensional measurements to evaluate leg lengthening, changes in global femoral offset (GFO) or TFRA, or PTA during THA. Accordingly, this study employs three-dimensional measurements to test our hypothesis that increased leg lengthening is associated with an increase in TFRA, which increases PTA and worsens postoperative m-Harris Hip Score (mHHS). Methods: A total of 111 consecutive patients who underwent THA were enrolled. THA-related changes in GFO, femoral version, TFRA, PTA, and leg lengthening. Relationships between each parameter and the m-Harris Hip Sc were also assessed using the intraclass correlation coefficient. Results: Leg lengthening was significantly positively correlated with changes in TFRA and PTA. However, changes in GFO negatively correlated with changes in TFRA and PTA. Moreover, changes in GFO and leg lengthening were the only factors affecting changes in TFRA and PTA, respectively. Conclusions: Direct relationships exist between changes in GFO and changes in TFRA and PTA. This may be related to increased tension of the adductor muscles and medial soft tissue around the knee, ultimately reducing strain on the patellofemoral joint and improving knee pain. Full article
