Introduction: The medial patellofemoral ligament is the primary stabilizer of the patellofemoral joint. Over the past decade, reconstruction has been recommended in adults with patellar instability. However, the reconstruction methods have not been standardized. The best graft and reconstruction methods have not yet been identified Methods: A 44-year-old female patient with knee unable to flex with pain following trauma. Patient underwent medial patellofemoral ligament reconstruction with quadriceps autograft. Arthroscopy was performed on anterolateral and anteromedial of the patella, obtained elongation and titling of the patella with medial articular surface defect, debridement was conduct. The MPFL reconstruction was done with the superficial quad graft technique, the end of the graft was sutured and measured, drilled the femur on the Schottle point using C-Arm guide according to the graft diameter. The graft is placed in the subvastus space, fixation of the graft with superior to inferior side switches, examined to ensure the stabilisation of the flexion and extension tension and fixated with screw Results: After the operation, the patient is able to perform regular daily activities without any complaints Conclusion: This study has found that medial patellofemoral ligament reconstruction using quadriceps autograft leads to an acceptable functional outcome for treating neglected unreduced patellar subluxation

One of the most common injuries in orthopaedic field is anterior cruciate ligament (ACL) tear, which accounts for more than 50% of all knee injuries and has an estimated incidence rate of 60.9 per 100,000 persons. Untreated ACL injuries may lead to postural instability, increase in meniscal injury rates, and osteoarthritis that develops more gradually. The gold standard treatment for ACL tears is arthroscopic reconstruction using an autograft or allograft tendon. However, graft failure during an ACL reconstruction (ACLR) can considerably delay recovery and lead to revision ACLR operation that has worse prognosis. A number of regenerative techniques, including stem cells, biomaterials, and bioactive compounds, have been researched and shown to be efficient. The injection of stem cells as biological augmentation has been suggested as a method to enhance the results of ACLR. Mesenchymal stem cells (MSC) in particular can differentiate into a number of terminally differentiated progenitors that can be used to create mesenchymal-derived tissues and to speed up the healing process by influence the microenvironment to promote angiogenesis, promote regeneration, and prevent the formation of scar tissue. The goal of this study is to outline the present use of stem cells as an augmentation in ACLR.
