  ABSTRACT: The purpose of this study was to investigate and report on a new intraoperative measuring technique to place the anterior cruciate ligament (ACL) femoral tunnel in the center of the native ACL femoral insertion site. We investigated a novel measuring technique based on identifying the proximal border of the articular cartilage and using a specific ruler parallel to the femoral axis to locate the origin of the ACL. The accuracy of this technique was validated by measuring tunnel position on postoperative 3-dimensional computed tomography scans. Bony tunnels created by the ruler technique were compared with tunnels drilled by a traditional technique referenced from the back wall of the notch. Fifty ACL reconstructions were performed by the novel measuring technique, with placement of the femoral tunnel at the center of the femoral insertion. The mean position for the center of the femoral tunnel measured by the ruler technique was 0.9 mm from the theoretic optimal center position but was a very distinct 5 mm from the mean position in the traditional tunnels. The ruler technique produced femoral tunnels comparable to published radiographic criteria used for tunnel placement and is reproducible and accurate. We recommend placement of the femoral tunnel at the midpoint of the lateral femoral condyle when using the anatomic single-bundle technique. Level IV, case series.

  ABSTRACT: TruFit plugs (Smith & Nephew, Andover, MA) are synthetic polymer scaffolds that are inserted into an articular surface to provide a stable scaffold to encourage the regeneration of a full thickness of articular cartilage to repair chondral defects. Our unit has shown promising early results for the repair of small articular cartilage defects within the knee. Other series have reported "failures" in which patients have complained of persistent symptoms and joint effusion at 6 months after plug insertion and arthroplasty has been undertaken. We report a case of delayed incorporation of an articular cartilage defect of the lateral femoral condyle treated with 3 TruFit plugs. The patient eventually reported symptom alleviation and resumption of functional activity after 24 months of continued rehabilitation. We recommend that patients with continued symptoms persevere with rehabilitation and allow the regenerating articular cartilage time to mature fully before considering undertaking irreversible arthroplasty procedures.
