Double Trouble: A Case Report of a Locked Knee Due to a Loose Body and a Degenerative Osteophyte.

An acutely locked knee is an incapacitating condition that requires urgent orthopedic intervention. Common causes of the locked knee include a tear of the meniscus, stump of a ruptured anterior cruciate ligament (ACL), loose body, and osteochondral injury. This report describes a rare case of an acutely locked knee due to the concurrent presence of a loose body and a degenerative osteophyte, highlighting the diagnostic challenges and treatment strategies employed for successful management. Notably, to our knowledge, there is no preceding report documenting the same etiology.

Comparison between the effect of immersive virtual reality training versus conventional rehabilitation on limb loading and functional outcomes in patients after anterior cruciate ligament reconstruction: A prospective randomized controlled trial.

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. Methods: This randomised controlled trial was undertaken in a tertiary hospital in Malaysia from July 2019 until July 2020. Thirty patients were randomised into a group undergoing purely conventional rehabilitation (Group 1) and a group undergoing both conventional rehabilitation and immersive virtual reality assisted rehabilitation (Group 2). The immersive virtual reality assisted rehabilitation was started at 3 months post operatively for 3 months duration. Limb loading, balance, range of motion, functional hop tests of the knee, pain and subjective scoring of the knee with the International Knee Documentation Committee (IKDC) Scores were measured preoperatively and at 6 months. Results: There were significant differences in terms of improvement of pain scores (p = 0.012) as well as IKDC Scores (p = 0.024) in Group 2 as compared to Group 1. However, there were no significant differences with regards to limb loading, balance, range of motion and functional hop tests of the knee (p > 0.05). No adverse events were observed during the study period. Conclusion: Immersive virtual reality can be used as an adjunct in rehabilitation of patients after ACL reconstruction in terms of improving their pain as well as their subjective knee evaluation. Large randomised control trial is recommended to further investigate the efficacy.

Popliteus Tendon Injury: A Rare Cause of Acute Locked Knee.

The acute locked knee is a common presentation of meniscal tears or other intra-articular injuries. However, a popliteus tendon tear, an uncommon cause of acute locked knee, is often overlooked as a possible diagnosis. Here, we present the case of a 29-year-old male who experienced an acute locked knee following a sports injury. An arthroscopic examination revealed an intrasubstance tear in the popliteus tendon and a complete anterior cruciate ligament tear, while the menisci remained intact. Due to the extension lag caused by the popliteus tendon tear, the anterior cruciate ligament reconstruction was postponed. The patient then underwent a course of physiotherapy before the anterior cruciate ligament reconstruction and eventually achieved full knee extension after six weeks. Further surgical intervention was then performed to address the ligament injury. Our case highlights the importance of considering a popliteus tendon tear as a possible cause of an acute locked knee. Proper diagnosis and management are crucial for achieving optimal outcomes for patients with an acute locked knee and concomitant ligamentous injury.

Shoulder Agony: A Painful Glenoid Cyst.

A ganglion cyst is a benign cystic lesion that can occur intraosseously. It is commonly a multiloculated lesion that consists of fibrous tissue with mucoid change and is usually located in the subchondral bone adjacent to the joint. Here, we present a rare case of a 33-year-old woman who presented to our orthopedic clinic with a five-year history of shoulder pain that gradually worsened. The pain was worst after any activity involving the right shoulder, and it also occurred at night and disturbed her sleep. Physical examination showed that the patient had limitations on the extreme range of movement. MRI revealed a subchondral bone cyst at the glenoid fossa. The ganglion cyst was subsequently curetted and packed with a bone graft from the iliac bone. Postoperatively, the pain resolved and the patient's range of movement improved. At the six-month follow-up, new bone formation over the void area caused by the cyst was observed on MRI.

Hsa-miR-181a-5p, hsa-miR-182-5p, and hsa-miR-26a-5p as potential biomarkers for BCR-ABL1 among adult chronic myeloid leukemia treated with tyrosine kinase inhibitors at the molecular response.

BACKGROUND: Tyrosine kinase inhibitors (TKIs) as first-line therapy for Chronic Myeloid Leukemia (CML) show a high success rate. However, a low number of patients with long-term treatment-free remission (TFR) were observed. Molecular relapse after imatinib discontinuation occurred at 50% at 24 months, with 80% occurrence within the first 6 months. One of the reasons for relapse is untimely TKIs discontinuation caused by large errors from estimates at very low-level or undetectable disease, thus warranting new biomarkers for CML. METHODS: Next Generation Sequencing (NGS) was used to identify microRNAs (miRNAs) at the molecular response in CML adult patients receiving TKIs treatment. A total of 86 samples were collected, 30 from CML patients responsive and 28 from non-responsive to imatinib therapy, and 28 from blood donors. NGS was conducted whereby 18 miRNAs were selected and validated by real-time RT-qPCR in triplicate. RESULTS: Hsa-miR-181a-5p was expressed significantly (p-value< 0.05) with 2.14 and 2.33-fold down-regulation in both patient groups, respectively meanwhile hsa-miR-182-5p and hsa-miR-26a-5p were significant only in the non-responsive group with 2.08 and 2.39 fold up-regulation. The down-regulation was consistent with decreased amounts of BCR-ABL1 in patients taking TKIs regardless of molecular responses. The up-regulation was consistent with the substantial presence of BCR-ABL1 in CML patients treated with TKIs at the molecular response. CONCLUSIONS: Therefore, these miRNAs have potential as new therapeutic biomarkers for BCR-ABL1 status in adult CML patients treated with TKIs at molecular responses. These could improve current approaches and require further analysis to look for targets of these miRNAs in CML.

Complete Androgen Insensitivity Syndrome: Diagnosis and Psychological Impact in Two Adolescents, A Case Report

@#This case report illustrates two cases of complete androgen insensitivity syndrome (CAIS) which is a rare form of sexual development disorder. Both presented with primary amenorrhea at the age of 18 and 19 years old. The hormonal profiles ruled out hypothyroidism, hyperprolactinemia, and primary ovarian failure. Magnetic resonance imaging of both patients showed the absence of uterus, fallopian tubes, ovaries, but the presence of proximal 1/3rd of the vagina. There is a single testis in the left inguinal region with unknown status of spermatogenesis. Women with CAIS are vulnerable to various psychological conditions caused by the appalling fact of being genotypically male when they have been raised female all their life. The gender confusion, reproductive issues, and how others perceive them require sensitive support. Hence, accentuate the need to explore and address the emotional, psychological, and psychiatric vulnerabilities, religious and spiritual beliefs in issues of relationships, infertility, and conception.
