A new surgical method is introduced offering a less invasive approach to reattach the medial retinaculum following acute patellar dislocation. This retrospective analysis comprised 12 cases of medial retinacular repair in 10 patients. The surgical technique achieved reinforced reattachment of the torn region of the medial retinaculum for improved patellar support and stabilization. During follow-up, no recurrent patellar dislocations occurred, except where one patient reported a subjective feeling of patellar dislocation. The average Kujala score for our sample group after 2 years was 89.2. A plethora of methods are described in the literature to repair a tear to the medial patellofemoral ligament, which attaches at the superomedial patella. However, it is our contention that traumatic patellar dislocation invariably results in osteochondral avulsion at the inferomedial patella, refuting medial patellofemoral ligament involvement, and, rather, implicating the inferior aspect of the deep layer of medial retinaculum. Our surgical technique enables stable fixation of the region, decreasing the rate of recurrent dislocations. No grafts are used, permitting tendinous and ligamentous anatomy to remain intact. We further postulate that performing a CT examination preoperatively may reduce time between diagnosis and surgery, in addition to locating fracture sites more precisely.

Lower eyelid function and appearance depend on the complex anatomic relationship between the soft tissue lamellae, supportive tarsoligamentous sling, and bone. Aging in the lower lid area may be caused by changes in the anterior lamella (skin and orbicularis oculi muscle), middle lamella (orbital septum and lower lid fat pads), posterior lamella (tarsus, lower eyelid retractors, and conjunctiva), tarsoligamentous sling (lateral retinaculum), or any combination of the previously described.

Article Synopsis
  • Partial quadriceps tendon ruptures can often be treated without surgery if the knee's extension mechanism is still functional, but complete ruptures usually require surgical repair for better recovery outcomes.
  • The surgical procedure involves making a midline incision over the knee to access and repair the quadriceps tendon, possibly using techniques like transosseous tunnels or suture anchors to secure the tendon properly.
  • The surgery aims to restore the function and mobility of the leg’s extensor mechanism by utilizing specific suturing patterns and techniques to secure the tendon back to the patella.

Introduction: This study aimed to evaluate the effectiveness and safety of a combined surgical approach for treating complex patellofemoral instability. This approach combines four procedures: medial patellofemoral ligament (MPFL) reconstruction with the quasi-anatomic technique, lateral retinaculum release, anteromedialization and distalization of tibial tuberosity and patellar/femoral mosaicplasty.

Material And Methods: Between August and November 2021, we enrolled 27 patients in the study (21 females, 6 males, average age 28.

Tarsal tunnel syndrome is an entrapment neuropathy of the posterior tibial nerve beneath the flexor retinaculum that can be precipitated by either intrinsic or extrinsic factors. We report a unique case of a posterior medial ankle joint capsular defect with localized fluid extravasation between the flexor digitorum longus and flexor hallucis longus leading to symptoms consistent with tarsal tunnel syndrome in a collegiate tennis player. This patient is a 19-year-old female with no past medical history who presented with symptoms consistent with tarsal tunnel syndrome.

Article Synopsis
  • Lateral patellar dislocation often damages the medial retinaculum and the medial patellofemoral ligament (MPFL), requiring stabilization of the medial soft tissue.
  • Treatment options include MPFL repair, reconstruction, or medial retinacular plication, but MPFL reconstruction can be too invasive for young females due to potential donor site issues.
  • The authors suggest a less invasive arthroscopic-assisted medial retinacular plication technique for acute dislocations, which provides effective stabilization with improved cosmetic results.
