A series of surgically treated patellar tendon lesions among athletes is presented. The material was collected during 5 years from three sports injury clinics and from two hospitals. During this period the authors treated about 150 cases of jumper's knee, of which 34 cases were treated by operation. The athletes were mostly volley ball players, jumpers or runners. The operation revealed a necrotic focus of the patellar tendon in 21 cases, the retinaculum was thick and adherent in 16 patients and an exostosis of the patellar insertion was seen in two cases. The necrotic areas were excised, the thick and adherent retinaculum was divided and the exostoses were excised and drilled. Surgical treatment of chronic patellar tendon pains may give good results in selected cases.

Background: Asymmetric landing kinetics 6 months after anterior cruciate ligament reconstruction (ACLR) are associated with higher risk of second anterior cruciate ligament injury. Little is known about landing kinetics after ACLR with an all-soft tissue quadriceps tendon (QT) autograft despite its increasingly common use in young, active patients.
Purpose/hypothesis: The purpose of this study was to compare landing kinetics during a bilateral drop vertical jump (DVJ) 6 months after ACLR in participants who had undergone primary ACLR with a QT or bone-patellar tendon-bone (BTB) autograft.

Purpose: The aims of this study were to compare (1) the rate of anterior cruciate ligament (ACL) revision and (2) subjective knee function using the Knee injury and Osteoarthritis Outcome Score (KOOS) between isolated ACL reconstruction (ACL-R) and ACL-R and concurrent meniscal injury, based on graft selection and meniscal treatment.
Methods: Data from the Swedish National Knee Ligament Registry were extracted in November 2022 for patients who underwent primary ACL-R. Patients were divided into two main groups based on graft choice: hamstring tendon (HT) or patellar tendon (PT) autograft, with four meniscal sub-groups: no injury, resection, repair or left in situ.

Introduction: Prosthetic silicone liners improve comfort and skin protection and allow the use of total surface bearing (TSB) sockets, which provide enhanced proprioception and comfort. Unfortunately, silicone liners are cost-prohibitive in resource-limited environments (RLEs) where patellar tendon bearing (PTB) sockets with PE-lite liners remain standard, leading to patient discomfort and skin issues.
Objective: This study evaluates the benefits and durability of an affordable silicone liner locally manufactured in an RLE to promote TSB socket adoption, aiming to enhance prosthetic care and patient outcomes.

Purpose: To review outcomes of medial patellofemoral ligament reconstruction (MPFLR) using synthetic suture tape in biomechanical and clinical studies.
Methods: A comprehensive literature search was performed in three databases. Studies reporting biomechanical and/or clinical outcomes of MPFLR using synthetic suture tape were included.

Background: Anterior cruciate ligament reconstruction (ACLR) often involves harvesting a bone-patellar tendon-bone (BPTB) autograft. How graft harvest affects tendon strain across the 3 distinct regions (medial, lateral, and central) is not known.
Purpose: To (1) quantify strain in the 3 regions of the patellar tendon during 60% of maximum voluntary isometric contraction (MVIC) in 90° of knee flexion and (2) assess how effort level in 2 different knee joint angles (60° and 90°) impacts strain in the medial and lateral regions of the patellar tendon, in 2 cohorts of patients after ACLR using a BPTB autograft (one group <24 months after surgery and another group ≥24 months after surgery).
