The aim of this pilot study was to determine if exaggerated patellar tendon jerk affects knee joint position sense (JPS) in cerebral palsy (CP) patients, by comparing JPS of the knee between participants with normal and exaggerated reflexes. The thresholds for reflex classification were based upon the data from able-bodied volunteers. JPS was measured as the ability of a subject (with eyes closed) to replicate a knee joint position demonstrated by an examiner. Tendon jerk was measured as the moment of force in response to patellar tendon taps. Data was collected from 27 limbs of CP patients (N=14) and 36 limbs of able-bodied volunteers (N=18). JPS was less accurate (p=0.014) in limbs with non-exaggerated reflexes (50.28±43.63%) than in control limbs (11.84±10.85%). There was no significant difference (p=0.08) in JPS accuracy between limbs with exaggerated reflexes (18.66±15.50%) and control limbs. Our data suggests that one component of sensorimotor impairment, JPS, is not as commonly affected in CP patients as previously reported. JPS of the knee is reduced in limbs with non-exaggerated reflexes; however in limbs with exaggerated reflexes which is seen in the majority of CP patients, JPS is not affected.

Effect of surgical treatment on relative tibial external rotation in patients with recurrent patellar dislocation.
Knee

Graduate School of Guangzhou University of Chinese Medicine, Guangzhou, Guangdong, China; Second Affiliated Hospital of Guangzhou Medical University, Guangzhou, Guangdong, China. Electronic address:
Background: In the knee joints of patients with recurrent patellar dislocation (RPD), an increased relative tibial external rotation (rTER) is often observed. However, the changes in this parameter pre- and postoperatively remain unclear.
Purpose: The purpose of this study was to reveal preoperative and postoperative changes in rTER in patients with RPD.
Association Between Autograft Choice and Psychological Readiness to Return to Sport After ACL Reconstruction.

Background: It has been demonstrated that an athlete's psychological readiness contributes to one's ability to successfully return to sport (RTS) after anterior cruciate ligament (ACL) reconstruction. However, the effect of graft choice on psychological readiness is not yet understood.
Purpose/hypothesis: The purpose of this study was to evaluate the association between graft choice and an athlete's psychological readiness to RTS.
Background: Quadriceps dysfunction is ubiquitous after anterior cruciate ligament (ACL) reconstruction (ACLR). Addressing quadriceps dysfunction is crucial to improve function, reduce the reinjury risk, and maintain long-term knee health. While deficits specific to the quadriceps are well documented, less is known about the effect of an ACL injury on other lower extremity muscle groups.

Introduction: Intramedullary tibial nailing is a standard treatment for tibial shaft fractures. Postoperative knee pain significantly impacts functional recovery; however, studies on this issue are limited. This study evaluated the effect of the parapatellar approach for intramedullary nailing on postoperative knee pain.

Introduction: Revision quadriceps tendon repair is a challenging problem. In this four-case series, novel quadriceps tendon revision resulted in improved range of motion and durable repair for patients with recurrent rupture.
Methods: Our technique includes a combination of a running locked #5 FiberWire or 2 mm SutureTape suture placed through parallel medial, lateral, and central drill holes in the patella with running Krackow-type quadriceps tendon repair medially and laterally resulting in four strands, delivering the vastus medialis and medial quadriceps tendon to an anatomic repair at the superior pole of the patella, with 2 sutures passed centrally and 1 each passed medially and laterally and then tied.
