PURPOSE: Anterior cruciate ligament injury (ACL) commonly occurs during sporting events. It causes pain, instability and reduction in range of movement of the knee which results in altered balance, reduced strength as well as loading to the involved knee. The challenge to get the patient back to competitive sports level much depends on the rehabilitation process. Post ACLR rehabilitation is challenging due to the long rehabilitation time as well as boring repetitive exercises. The aim of this study is to compare between the effectiveness of using immersive virtual reality (PlayStation VR) in addition to the conventional rehabilitation as an aid in rehabilitation of patients after ACLR in terms of objective functional assessment and pain and subjective knee function scoring...

OBJECTIVE: Joint stiffness results from the coupling of the nervous system and joint mechanics, and thus stiffness is a comprehensive representation of joint stability. It has been reported that moxibustion can alleviate general weakness and fatigue symptoms and subsequently may influence joint stiffness. This study investigated whether moxibustion could enhance knee joint stiffness in recreational athletes pre- and post-fatigue. METHODS: Eighteen participants were randomized into intervention (5 males: 20...

METHODS: The Functional Internal Rotation Scale was translated to Thai, including cross-cultural adaptations, following standard guidelines...

BACKGROUND: Failure to fix the fractured fragment can result in bony fragment resorption and consequent glenoid bone loss. Current arthroscopic repair techniques might lead to insecure fixation and refracture. The purpose of this study was to evaluate the effectiveness of the transosseous sling-suture technique for bony Bankart lesions, and to compare the clinical outcomes for acute and chronic bony Bankart lesions treated with this technique. METHODS: A retrospective case series consisting of 46 patients with bony fracture of the glenoid rim following traumatic injury was identified from May 2015 to August 2020...

BACKGROUND: This study aimed to investigate the effect of high tibial osteotomy (HTO) on medial meniscus extrusion (MME) and the association between the changes in limb alignment and MME under weight-bearing (WB) conditions after HTO. METHODS: We included 17 patients with knee osteoarthritis (OA) who underwent HTO. MME was evaluated using ultrasonography in supine and unipedal standing positions. Knee alignment was evaluated radiographically using WB, whole-leg radiographs with the hip-knee-ankle angle (HKAA), percentage of the mechanical axis (%MA), medial proximal tibial angle (MPTA), and joint line convergence angle (JLCA)...

The posterior circumflex humeral artery, a branch of the axillary artery, is compressed by the humeral head during repeated abduction and external rotation of the shoulder joint owing to its anatomical structure. This damages the vascular endothelium, resulting in thrombi, arterial dissection, and aneurysms, a condition known as posterior, circumflex humeral artery pathological lesions. A thrombus may form at the site and becomes a peripheral embolus, resulting in peripheral arterial occlusion.A 21-year-old right-handed elite man college volleyball player noticed coldness and pain in his right hand during a game...
