“…Resecting the PCL in general led to an increase in gap height with flexion, as expected from previous reports [4,18,25]. PCL resection caused the tibia to drop with respect to the femur in flexion, opening up the medial and lateral compartments and generally loosening the knee.…”

“…The latter two studies included no information on how many patients reacted with a relevant flexion-gap increase. Baldini and coworkers reported on 50 patients with varus and valgus deformity and found a symmetrical effect from the PCL release of 1.3 mm on the joint gap in extension and 90°flexion [12]. A flexion-gap increase >2 mm was measured in 26% of patients.…”

“…In this context, we investigated high flexion grades and found that the biggest joint-gap increase was between 110°and 140°. To our knowledge, all other studies focused only on the joint gap between full extension and 90° [9,12,13,[16][17][18][19][20][21]. The proven increase in high flexion grades might be the reason for the higher range of motion that was frequently detected after posterior stabilised prostheses in comparison with posterior cruciateretaining prostheses [22][23][24].…”

“…Nonetheless, it remains unsettled how wide, in proportion to the prosthetic components, the gaps should be distracted. Baldini et al 29 propose that for the majority of osteoarthritic (OA) knees undergoing posterior stabilized TKA, PCL removal and re-establishment of the posterior recess does not require additional consideration for gap balancing. This may be partially relevant for the posterior stabilized concept, which perhaps compensates for some gap differences.…”
