The First Bilateral Staged Oxford Cementless Unicompartmental Knee Arthroplasty in Louisiana Following FDA Approval: A Case Report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We present the case of a 63-year-old woman with bilateral medial compartment osteoarthritis who underwent the first staged bilateral cementless Oxford unicompartmental knee arthroplasty (OUKA) performed in the state of Louisiana shortly after its FDA approval in 2024. The patient had a five-year history of progressively worsening knee pain refractory to conservative therapy, including corticosteroid injections and physical therapy. Imaging confirmed isolated medial compartment disease with preserved lateral compartments and intact cruciate ligaments. Following the right OUKA, she demonstrated rapid recovery, full extension, and near-complete resolution of pain within four weeks. Due to persistent pain in the contralateral knee, a left OUKA was performed six weeks later with similarly favorable results. Postoperative imaging confirmed appropriate prosthesis positioning bilaterally without evidence of loosening, migration, or malalignment. The patient resumed full ambulation and reported restoration of functional capacity. This case highlights the early postoperative benefits and potential long-term promise of cementless OUKA, including faster recovery, reduced surgical time, and avoidance of cement-related complications. The implant's titanium and hydroxyapatite coating may further enhance biological fixation and durability. As cementless technology gains traction in the United States, continued follow-up and longitudinal studies will be essential to confirm its long-term survivorship and clinical efficacy compared to traditional cemented designs.
