... Unicompartmental knee arthroplasty (UKA) may be suitable for patients with degenerative changes limited to a single compartment, as it preserves cartilage in the other compartments [150,151]. In cases where the pathological process extends to the other compartments, or in severe SIFKinduced OA, TKA is the predominant and reliable treatment choice [152,153]. At stages where joint degeneration is assessed as mild to moderate, a selection of joint-preserving surgical options is considered viable. ...

[12][13][14] Additionally, it can be used to combat rotatory instability, which is a common cause of primary reconstruction failure. 15 Many techniques have been described regarding Achilles tendon allograft preparation and use in ACLR. ...
... ACL reconstruction (ACLR), a well-established procedure, restores knee joint stability, improves function, and supports an eventual return to sports. Although the advances in surgical techniques and improved understanding of the ACL anatomy and biomechanics have improved clinical outcomes, residual rotatory instability (related to unsatisfactory clinical outcomes and risks of re-tear) was observed in 25% of the patients [2] . One cause of the increased risk of re-injury and performance declines is attributed to the diminished proprioception after an ACL rupture. ...
... These fractures are not only a leading cause of hospitalization but also carry a high risk of mortality, particularly in older populations. Complications, such as pneumonia, pulmonary oedema or effusion, and pulmonary thromboembolism, can worsen the prognosis of these patients [3][4][5]. In long bone fractures, such as femur fractures, the release of bone marrow and fat emboli into the bloodstream is a significant concern [6,7]. ...
... Osteoporosis is a prevalent and consequential condition, causing degradation of bone microarchitecture, notably in the hip and spine; weakened bone durability; and increased susceptibility to osteoporotic fractures [1]. With an increase in life expectancy, the incidence of osteoporosis is projected to continue to rise [2]. ...

... Medial opening-wedge high tibial osteotomy (MOWHTO) is a reliable treatment option for medial compartment osteoarthritis of the knee with varus alignment in young patients [1]. The benefits of MOWHTO have been demonstrated in multiple studies showing satisfactory clinical results, slowed progression of knee osteoarthritis, and delayed conversion to total knee arthroplasty (TKA) [2][3][4][5][6][7][8]. ...
