Combined Medial Quadriceps Tendon-Femoral Ligament and Medial Patellofemoral Ligament Reconstruction for Revision Patellofemoral Soft-Tissue Stabilization

Arthroscopy Techniques
Patients with recurrent patellofemoral instability in whom prior medial patellofemoral ligament (MPFL) reconstruction fails present unique challenges for revision soft-tissue stabilization owing to scar tissue formation, limited patellar bone stock for ...

Patellar instability: arthroscopic surgery, indications and techniques

Acta Orthopaedica et Traumatologica Turcica, 2020
A significant incidence of knee pain and disability arise fro m patellofemoral disorders. An accurate diagnosis relies both on a comprehensive history and a careful physical examina - tion; radiologic modalities also play an important part in the ...

Lower patella–patellar tendon angle is associated with increased odds of patellofemoral osteoarthritis progression in ACL revision patients: A case control study

Journal of Experimental Orthopaedics, Volume 13, Issue 4, October 2026.
Abstract Purpose To investigate whether a lower preoperative patella–patellar tendon angle (P‐PTA) is associated with progression of patellofemoral osteoarthritis (PFOA) in patients undergoing anterior cruciate ligament (ACL) revision surgery. We hypothesised that patients with lower preoperative P‐PTA would have higher odds of PFOA progression ...

Excellent survivorship and functional outcomes following lateral unicompartmental knee arthroplasty in patients aged 55 years or younger

Journal of Experimental Orthopaedics, Volume 13, Issue 4, October 2026.
Abstract Purpose Fixed‐bearing lateral unicompartmental knee arthroplasty (UKA) is a bone‐ and ligament‐preserving treatment option for isolated lateral‐compartment osteoarthritis (OA), but evidence in younger patients remains limited. The primary purpose of this study was to assess lateral component revision‐free survival and reoperation‐free survival

Impact of Femoral Derotation Osteotomy on Patellofemoral Loading in Patients With Patellofemoral Instability: Insights From a Musculoskeletal Simulation Study

Journal of Orthopaedic Research, Volume 44, Issue 10, October 2026.
ABSTRACT Increased femoral version is linked to patellofemoral instability, increased lateral loading of the patella and might be treated with femoral derotation osteotomy (FDO) in excessive cases. However, the effects of FDO on patellofemoral stability and loading while walking are not fully understood and not measurable in vivo.

Surgical anatomy of the medial patellofemoral complex

Journal of Cartilage & Joint Preservation
: Patellar instability is a common cause of knee dysfunction in young individuals. The medial patellofemoral complex (MPFC), comprising the medial patellofemoral ligament and medial quadriceps tendon femoral ligament (MQTFL), plays a crucial role in ...

Rethinking Knee Arthroplasty: Bicompartmental Unicompartmental Knee Arthroplasty as a Biomechanically Personalized, Function‐Preserving Solution for Knee Osteoarthritis

Orthopaedic Surgery, Volume 18, Issue 10, Page 2101-2117, October 2026.
A comparative study of bicompartmental unicompartmental knee arthroplasty (bi‐UKA) and total knee arthroplasty (TKA) in patients with bicompartmental osteoarthritis. The image illustrates key anatomical differences in implant design, outlines the study population (bi‐UKA: n = 35, TKA: n = 45), and highlights functional evaluation metrics including the ...

Kinematic Alignment in TKA Using the Contralateral Healthy Knee as Reference: A Combined Finite Element and Clinical Analysis

Orthopaedic Surgery, Volume 18, Issue 10, Page 2205-2216, October 2026.
In patients with unilateral knee osteoarthritis, a novel natural kinematic alignment (NKA) using the contralateral healthy knee as reference was compared with mechanical alignment (MA) and kinematic alignment (KA) via finite element analysis and a clinical study. NKA provided more balanced stress in neutral/mild varus models.

The Influence of Running Cadence Manipulation on Acute Cartilage Response in Distance Runners

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 10, October 2026.
ABSTRACT We examined the influence of running cadence manipulation on femoral cartilage deformation in runners and assessed the association between knee biomechanics and cartilage characteristics. Thirty‐one runners (15 females and 16 males) completed a habitual and high cadence (+10%) run 2–7 days apart in a counterbalanced order.
