[1] on posteromedial geometric parameters associated with ramp lesions in ACL‑injured knees and greatly benefited from it. The authors found that PMMPO‑I and medial meniscal slope, i.e. MMS, were independently associated with ramp lesions, providing promising new indicators for preoperative MRI assessment. We particularly appreciate the precise definition of novel parameters such as PMMPO‑I, which further highlights the importance of meniscal morphology in posteromedial compartment mechanics.

[1]. The authors recruited a large cohort of young healthy knees and patients with end-stage knee osteoarthritis (OA), built a standardized cylinder-based kinematic pipeline, and generated normative pivot reference data. This work delivers a valuable baseline for tibiofemoral biomechanical research. However, several key methodological and statistical shortcomings reduce the reliability and clinical applicability of their conclusions regarding pathological OA pivot patterns for total knee arthroplasty (TKA) alignment planning.

We agree that dynamic knee kinematics remain highly complex and that further studies are required to better understand physiological and pathological motion patterns. However, we believe several comments arise from a misunderstanding of the aims and interpretation of our study.

Patients are presenting at a younger age, with higher functional demands and older patients with associated medical co-morbidities. It is commonplace for patients to outlive their knee prosthesis and therefore strategies into investigating and manging patients who come to require revision total knee arthroplasty is important.
