Titanium cannulated lag screw versus titanium cable-cannulated lag screw tension band for treatment of transverse patellar fractures

Although the titanium cable-cannulated lag screw tension band (TCCLSTB) technique is an effective method for fixation of transverse patellar fractures, it has shortcomings, such as extensive soft tissue damage and complex manipulation. We conducted a retrospective comparison of the titanium cannulated lag screw (TCLS) and TCCLSTB technique. We retrospectively reviewed 74 patients with transverse patellar fractures (38 in the TCLS group and 36 in the TCCLSTB group). Follow-up was at least 1 year (range, 1-3 years). Comparison criteria were operation time, operative incision, fracture reduction, fracture healing time, the Iowa score for knee function, and complications. The TCLS group showed shorter operation time, lesser operative incision and equal fracture reduction, fracture healing time, and knee function compared with the TCCLSTB group. There was no complication in the both groups. The TCLS technique without the cost of titanium cable tension band saved the operation time and had lesser operative incision. Therefore it should be considered as an alternative method for treatment of transverse patellar fractures.
