Minimal invasive and computer-assisted total knee replacement compared with the minimal invasive technique: a prospective, randomized trial with short-term outcomes
Abstract Introduction Up to now , no prospect i ve , r and omized comparisons between minimal invasive and computer-assisted total knee arthroplasty ( MICA-TKA ) , and minimal invasive technique ( MI-TKA ) has been documented to evaluate not only clinical , but also radiologic results of the MICA-TKA . This prospect i ve , r and omized study was performed to compare the short-term results of MICA-TKA with minimal invasive technique MI-TKA for 6-month follow-up . Patients and methods We reported the clinical and radiological results of 80 subjects who had cruciate-substituting , TKA-implanted primary total knee arthroplasties using either minimal invasive and computer-assisted technique ( 40 patients Group I ) or minimal invasive technique ( 40 patients , Group II ) .  Tourniquet time , length of skin incision , and total blood loss were compared . Knee society scores ( KSSs ) , knee society functional scores ( KSFSs ) , range of motion ( ROM ) , and radiographic results were assessed and reported preoperatively and at 6-month follow-up . Results The accuracy of the implantations in relation to the coronal mechanical axis in Group I was superior to that of Group II ( P < 0.05 ) . The femoral rotational profile revealed the prosthesis in Group I that was implanted with significantly less internal rotation than in Group II . The average blood loss in patients of Group I was significantly reduced as compared to patients of Group II . No significant difference was detected in terms of tourniquet time or length of skin incision . Clinical results , with regard to ROMs and KSSs , as well as KSFSs were equally good in both the groups . Conclusions Better alignment and similarity of good clinical results at short-term follow-up may provide subjects who receive MICA-TKA with long-term endurance of their implants . Further studies on longer-term outcomes and functional improvements are required to vali date these possibilities
