    Abstract Aim: To evaluate the functional outcomes of patients undergoing arthroscopic arthrolysis of the knee and find the ideal timing for arthrolysis to achieve maximum range of motion (ROM) of the knee.
    Methods: All patients who underwent arthroscopic arthrolysis for post-operative joint stiffness following surgery for injuries around knee joint at a tertiary care centre from 2009 to 2023 were included in this study. The patients' details such as primary injury, time interval between the index surgery and arthrolysis, improvement in knee range of ROM and Lysholm score from prior to arthrolysis to last follow-up post arthrolysis were retrieved from hospital database and analysed.
    Results: Total of 42 patients who underwent arthroscopic arthrolysis of knee from 2009 to 2023 were included in this study. Follow-up range was 6 months to 6 years. ROM after arthrolysis significantly improved in the early and delayed arthrolysis groups as compared to late arthrolysis groups (mean 126.25 and 115.62 vs 106.3,
    Conclusions: Arthroscopic arthrolysis done within 6 months (with maximum effect when done within 3 months) after the primary surgery leads to significant improvement in ROM and functional scores as compared to those with late arthrolysis group.

    Abstract Introduction: Total hip arthroplasty (THA) has revolutionized the treatment of hip joint arthritis. With the increased popularity and success of the procedure, research has focused on improving implant survival and reducing surgical complications. Optimal component orientation has been a constant focus with various philosophies proposed. Regardless of the philosophy, achieving an accurate acetabular position for each clinical scenario is crucial. In this paper, we review the recent developments in improving the accuracy and ideal positioning of the acetabular cup in routine primary THA.
    Methodology: A review of the recent scientific literature for acetabular cup placement in primary THA was performed, with available evidence for safe zones, spinopelvic relationship, preoperative planning, patient-specific instrumentation, navigation THA and robotic THA.
    Conclusion: Though the applicability of Lewinnek safe zones has been questioned with an improved understanding of spinopelvic relationships, its role remains in positioning the acetabular cup in a patient with normal spinopelvic alignment and mobility. Evaluation of spinopelvic relationships and accordingly adjusting acetabular anteversion and inclination can significantly reduce the incidence of dislocation in patients with a rigid spine. In using preoperative radiography, the acetabular inclination, anteversion and intraoperative pelvic position should be evaluated. With improving technology and the advent of artificial intelligence, superior and more accurate preoperative planning is possible. Patient-specific instrumentation, navigated and robotic THA have been reported to improve accuracy in acetabular cup positioning as decided preoperatively but any significant clinical advantage over conventional THA is yet to be elucidated.

    Abstract Introduction: This simulation study on MRI of the knee was performed to assess the risk of injury to the popliteal artery (PA) and common peroneal nerve (CPN) during all-inside meniscal repairs in adults.
    Methods: We simulated repair of the posterior horn of both medial (PHMM) and lateral menisci (PHLM) through anteromedial (AM) and anterolateral (AL) portals, using straight and curved devices, on 200 magnetic resonance imaging (MRI) scans taken with the knee in extension. For simulation using straight devices, the shortest distance from the menisco-capsular junction (MCJ) and the free edge of the meniscus to PA and CPN in vectors of AM and AL portals was measured. In curved devices, the closest extracapsular distance from the device tip to PA was measured.
    Results: With a straight device through AM portal, the mean distance from the MCJ of PHMM to the PA was 20.7 ± 3.15 mm (13.5-27.4). In PHMM repair through AM portal using a curved device, the mean extracapsular distance from the device tip to PA was 18.8 ± 4 mm (7.7-27.2) while pointing toward and 26 ± 4.5 mm (15.5-35.6) while pointing away from the midline. When using straight devices, the average distance from free edge of LM to PA was 18.5 ± 3.3 mm (9.6-31.2) and from MCJ to PA was 8.9 ± 2.4 mm (3.5-18.8). The average distance measured from the MCJ to CPN through AM and AL portals using straight devices was 19.4 ± 2.8 mm (10.2-32.5) and 22 ± 2.8 mm (10.4-36.7) respectively.
    Conclusion: In adults, PA is safe in PHMM repairs using both straight and curved devices irrespective of depth and direction of insertion. In PHLM repairs, the PA is at risk with both straight and curved devices. We recommend adjusting the depth of insertion to as minimum as possible to just penetrate the capsule. The CPN is safe in LM repairs using all-inside devices.

    Abstract Introduction: We propose a possible mechanism of dislocation in a posterior stabilized (PS) total knee arthroplasty (TKA) and suggest that it can be treated like a stable posteriorly dislocated hip replacement if stable throughout the range on examination under anesthesia.
    Case report: A 71-year-old female presented with the right posterior knee dislocation following 1 year of TKA. Following the successful relocation, the knee was found to be stable throughout the range of movement and an uneventful recovery at 3 years follow-up.
    Conclusion: Dislocation can occur in an otherwise stable TKA while squatting and can be successfully treated closed. The patients should be counseled to avoid squatting in a non-high flexion PS knee.
