Injuries to the patellar tendon (PT) are associated with knee function deterioration and loss of the capacity to perform daily and sports activities. Patellar tendon injury is often misdiagnosed at emergency rooms, leading to chronic proximal retraction and a challenging clinical scenario. Proximal PT injuries are more common, while distal ones, which can involve tibial bone avulsion fractures or direct tendon avulsion, are rarer. The low incidence of distal PT rupture and the variety of injury patterns make a personal approach reasonable when based on the intraoperative findings and the surgeon's experience. Our purpose is to describe a surgical technique to restore the knee extensor mechanism after chronic distal PT rupture using two kinds of graft, one as a waveform augmentation of the native tendon and the other as reinforcement in a letter X aspect.

Objective: To investigate the relationship between impaired gliding in the anterior knee region and anterior knee pain (AKP) in patients after total knee arthroplasty (TKA).
Design: Cross-sectional study.
Setting: Orthopedic hospital PARTICIPANTS: Patients aged >60 years who underwent TKA between June and September 2023 without abnormal components or postoperative infections.
Thin flap sulcus-deepening trochleoplasty in patellar instability yields good functional outcomes without progressive cartilage deterioration in the short-term follow-up-A retrospective single-surgeon cohort study.
Knee Surg Sports Traumatol Arthrosc
December 2024
Sporthopaedicum, Berlin, Germany.
Purpose: Sulcus-deepening trochleoplasty (TP) effectively treats patellofemoral (PF) instability (PFI) caused by high-grade trochlear dysplasia (TD), but current evidence is based on small case series. We hypothesised, that TP would result in significant functional improvements and a low re-dislocation rate but would not accelerate the progression of PF cartilage deterioration.
Methods: We retrospectively reviewed all TP cases performed by a single surgeon between 2015 and 2021.
Femoral tunnel enlargement after medial patellofemoral ligament reconstruction is common and can be monitored using plain radiographs.

Introduction: medial patellofemoral ligament reconstruction (MPFLr) is a common surgical procedure for treating patellar instability. Grafts can be fixed to the femur using a bone-tunnel technique with an interference screw. However, this may lead to femoral tunnel enlargement (FTE) post-operatively.

J Sci Med Sport

Department of Orthopedics and Sports Medicine, Erasmus MC University Medical Center, the Netherlands.
Objectives: To investigate whether the effectiveness of progressive tendon loading exercises (PTLE) on patellar tendinopathy is mediated through changes in physical or imaging properties.
Design: Mediation analyses based on a randomized clinical trial (n = 76) in patellar tendinopathy comparing PTLE with eccentric exercise therapy (EET).
Methods: Pain-related disability on Victorian Institute of Sports Assessment-Patella (VISA-P, 0 to 100) and pain (Visual Analogue Score) after single-leg decline squat (VAS-SLDS, 0 to 10) at 24 weeks were outcome measures.
