ABSTRACT Introduction: The anterior cruciate ligament (ACL) is one of the important structures of knee joint stability. Objective: To investigate the application of medical training therapy (MTT) in the functional recovery of patients after anterior cruciate ligament reconstruction. Methods: Eighty patients who were treated in a secondary hospital were selected as the study subjects and were divided into a control group and an observation group according to a random number meter, with 40 cases per group. We compared Lysholm knee function scores, the range of motion (ROM), daily life capability (ADL scale), pain degree (VAS rating), knee stretch muscle score, and standing balance ability score of the two groups 3 months after intervention. Results: After intervention, the first time getting out of bed, the doctor-patient satisfaction score, and the average length of stay were better in the observation group than in the control group (P<0.05). The excellent rate of knee function in the observation group was 92.50%, which was significantly higher than 70.00% in the control group (P<0.05). Conclusions: MTT therapy can significantly improve knee the function and pain level of patients after anterior cruciate ligament reconstruction, shorten the length of hospital stay, promote rehabilitation, improve the therapeutic effect, and improve the quality of life of patients. Level of evidence II; Therapeutic studies - investigation of treatment results.

Acute anterior cruciate ligament (ACL) is a key structure that stabilizes knee joints. The objective of this research is to investigate the influence of ligament remnants preserved on the tendon-bone healing following ACL reconstruction and to examine postoperative articular cartilage degeneration in rabbit as a model animal. Sixty New Zealand rabbits are randomly divided into an ACL reconstruction without remnant preservation group (Group A; n = 30) or ACL reconstruction with remnant preservation group (Group B; n = 30). The expression of HIF-1α, VEGF, and micro vessel density (MVD) in the transplanted tendon was detected by immunohistochemical staining at week 6 and 12 after the operation. The signal intensity of the transplanted tendon was observed by MRI scanning, and the width of the bone tunnel was measured by CT scanning at week 6 and 12 after the operation. The graft biomechanics was tested 12 weeks after the operation. The JNK and MMP-13 expression levels were compared to analyze the cartilage degeneration of the knee at week 12 after the operation. The experimental results were analyzed and showed that the remnant-preserving ACL reconstruction is beneficial for bone healing of the tendon in rabbits, but ACL reconstruction with or without ligament remnants preserved will not affect knee articular cartilage degeneration post-surgery.

Background: Knee is one of the major joints involved in kinesis. With increasing involvement in sports related activities especially in young people, Trauma related knee pathologies have increased. An accurate diagnosis regarding the type and extent of injuries is essential for early operative as well as non-operative treatment. Methods:This prospective study included total of 82 cases. The patients were referred to the department of Radiodiagnosis from indoor and outdoor departments of Guru Nanak Dev Hospital, Amritsar with suspicion of internal derangement of the knee and with history of knee trauma.Results:The most common age group involved was young males between 15-34 years. In all age groups most of the patients were males. Most common ligament to be injured was Anterior Cruciate Ligament (ACL). Partial tears were more common than complete tears. Posterior Cruciate Ligament (PCL) tears were less common. Medial Collateral Ligament (MCL) tears outnumbered Lateral Collateral Ligament (LCL) tears and grade 2 tears were more common in both. Among the meniscal injuries Medial Meniscus (MM) tears were more common than LM and grade 3 signal was more common in both. Most of the patellar retinaculum injuries were associated with Anterior Cruciate Ligament ACL tears.Conclusions:Post-traumatic pre-arthroscopic MR imaging evaluation has proved to be cost-effective. MRI is an accurate imaging modality complementing the clinical evaluation and providing a global intra-articular and extra-articular assessment of the knee.
