Immediate effects of leg-press exercises with tibial internal rotation on individuals with medial knee osteoarthritis.

Objective: Although patients with knee osteoarthritis (OA) demonstrate abnormal kinematics involving greater tibial external rotation during squatting, there have not been any previous studies investigating an exercise focused on correcting knee rotational kinematics. This study aimed to determine the immediate effects of exercise with tibial internal rotation (IR) on symptoms and functions in patients with knee osteoarthritis (KOA).

Methods: This study provides Level II evidence using a small randomized controlled trial.

The relationship among psychological factors, neglect-like symptoms and postoperative pain after total knee arthroplasty.

Background: Persistent postoperative pain has a significant relationship with patient health and satisfaction.

Objectives: To investigate the prevalence and association of neglect-like symptoms (NLS) and other psychological factors on postoperative pain in patients following total knee arthroplasty (TKA). NLS are defined as the loss of perception of the limb with pain and excessive effort required to move the limb.

Adductor insertion avulsion syndrome mimicking neoplastic processes in a 14-year-old long-distance runner.

Adductor insertion avulsion syndrome, also known as thigh splints, is an uncommon condition that can mimic primary bone tumors or osteomyelitis. This article describes the clinical and imaging findings of adductor insertion avulsion syndrome in a 14-year-old male long-distance runner. The patient presented with a 1-month history of progressively worsening pain in the medial aspect of the left thigh.

Tibial tubercle transfer on a medial periosteal pedicle--a report of a new technique.

Tibial tubercle transfer is still probably the most widely used procedure of the numerous operative procedures described to realign the patella and extensor mechanism and to prevent a recurrent dislocation. Although this procedure most likely disturbs the blood supply to the tibial tubercle and thus may lead to a delayed union. Tibial tubercle transfer is also considered to play a role in the incidence of a tibial tubercle delayed union.

Bilateral meniscal cysts of medial menisci occurring in a career soldier.

A young male career soldier presented with bilateral meniscal cysts of the medial menisci combined with a meniscal tear. This was confirmed by magnetic resonance imaging and was treated by arthroscopic procedures. An arthroscopic examination showed mucous fluid to be leaking from a torn portion of his left knee; however, no similar leaking was observed in his right knee.

Magnetic resonance evaluation of remodeling process in patellar tendon graft.

Several studies have shown the accuracy of magnetic resonance imaging in evaluating the reconstructed anterior cruciate ligament. The purpose of the current study was to clarify the clinical usefulness of magnetic resonance imaging for evaluating the reconstructed anterior cruciate ligament in comparison with using arthroscopy. Sixty-nine patients who had an anterior cruciate ligament reconstruction using a bone-tendon-bone autograft were examined by magnetic resonance imaging and arthroscopy an average of 12 months after surgery.

The effect of wedged insoles on the lateral thrust of anterior cruciate ligament-insufficient knees.

Background: Patients with untreated anterior cruciate ligament insufficiency often develop osteoarthritis. In Japan, laterally or medially elevated insoles have been widely used for the relief of symptoms associated with unicompartmental osteoarthritis of the knee.

Hypothesis: The use of a valgus wedge in the shoe of a patient with anterior cruciate ligament insufficiency will decrease lateral thrust.

The influences of biomechanical factors on cartilage regeneration after high tibial osteotomy for knees with medial compartment osteoarthritis: clinical and arthroscopic observations.

Purpose: A high tibial osteotomy (HTO) is often performed on knees with medial compartment osteoarthritis. However, in varus knees with medial compartment osteoarthritis, degeneration of the articular cartilage tends to progress due to medial deviation of the mechanical axis. This can result in eburnated bone.

Magnetic resonance imaging evaluation after re-notchplasty at second-look arthroscopy.

Purpose: To clarify the effects of re-notchplasty on magnetic resonance imaging (MRI) for evaluating the reconstructed anterior cruciate ligament (ACL).

Type Of Study: Observational cohort study.

Methods: Twenty-one patients who underwent re-notchplasty at second-look arthroscopy were examined.
