Article Snippet: Cross pin system (Rigidfix) , The Cross pin system (Rigidfix) (DePuy Mitek Ltd) was introduced in 2003 for graft fixation in anterior cruciate ligament reconstruction. The implant consists of 2 bioabsorbable (poly‐L‐lactide) Rigidfix cross pins which are inserted across the graft through 2 parallel drill holes from the lateral femoral condyle perpendicular to the femoral socket made by a Rigidfix cross pin guide. Theoretical advantages of this implant are due to the expansion mechanism and include good structural properties, maintaining anterior knee stability, higher failure loads, the leeway for graft tunnel mismatch, lower synovitic reactions rate, relatively easy revision surgery and low complication rate. However, the resorbable pins are more expensive than resorbable screws. In addition, the pins penetrate the tendon graft in line with the collagen fibres, so slippage may occur as the collagen fibres separate under tensile stresses. The diameter of the pin is 3.3 mm for soft tissue and 2.7 mm for bone‐patellar‐tendon‐bone. The length is 42 mm..
