“…The benefits of minimally or lessinvasive techniques used in TKA remain unproven. Questions regarding whether limitations in exposure may lead to component malalignment have been studied, 1,8 but objective evaluation of whether cement fixation is compromised has not been examined in the literature. In the current study, the cement technique results obtained by a single surgeon using a less-invasive midvastus approach and a standard medial parapatellar approach were compared radiographically.…”

The purpose of this study was to assess the effects of a less-invasive midvastus exposure during total knee arthroplasty (TKA) on cement mantle grade compared with a standard parapatellar arthrotomy and standard TKA. Fifty consecutive cemented minimally invasive TKAs using a midvastus approach, patellar subluxation without eversion, and less-invasive instrumentation were compared radiographically with a control cohort of 50 consecutive cemented standard TKAs. To eliminate patient selection bias, the standard cohort included consecutive surgeries completed before 2004, prior to the advent of minimally invasive techniques in TKA. Analog supine anteroposterior and lateral radiographs were evaluated using Ewald's criteria. Lucent lines, cement voids, and cement debris were recorded for each group. Radiographic analysis revealed compromised femoral component cement mantle grades in the minimally invasive group. The number of anterior femoral cement voids (zone 1) was significantly higher in the minimally invasive group, and peripatellar and tibial cement debris was also more common in the minimally invasive group. Based on these findings, the midvastus approach compromises the surgeon's ability to duplicate a consistent femoral cement mantle obtained using a standard exposure.

“… Mini‐medial parapatellar approach 16 The incision into the quadriceps tendon should extend 2–4 cm above the superior pole of the patella. The arthrotomy should be of a sufficient length to sublux the patella laterally over the lateral femoral condyle with eversion. Mini‐midvastus approach 17,18 The incision should extend from 1 cm above the superior pole of the patella to the proximal half of the tibial tubercle on its medial side. A medial arthrotomy should extend from the superior pole of the patella to the level of the tibial tubercle.…”
