No clinical advantage with customized individually made implants over conventional off-the-shelf implants in total knee arthroplasty: a systematic review and meta-analysis.

This systematic review and meta-analysis compared clinical and radiological outcomes between conventional off-the-shelf (OTS) and customized individually-made (CIM) implants in total knee arthroplasty (TKA). The study found that:
– CIM implants were associated with higher revision rates (5.9% vs 3.7%), manipulation under anesthesia (MUA) rates (2.2% vs 1.1%), and overall complication rates (5% vs 4.5%) compared to OTS implants. However, these differences did not reach statistical significance.
– The length of stay was significantly shorter in the CIM group (2.9 days vs 3.5 days).
– There was no difference in the Knee Society Score between the CIM and OTS groups.
– More CIM TKAs were found to be in the hip-knee-ankle (HKA) target zone compared to OTS TKAs, but CIM implants did not improve overall target alignment.
The findings suggest that the general use of CIM over OTS implants in TKA is not supported.
