Summary: The study compared the effects of the measured resection (MR) technique and gap balancing (GB) technique on knee function and squat function in patients with knee osteoarthritis after primary total knee arthroplasty (TKA) in China. The results showed that GB technique had advantages over MR technique in terms of operation time, osteotomy volume, postoperative pain severity, knee range of motion, squat function, and complication rate.

Summary: The study found no significant differences in implant migration or inducible displacement between the gap balancing and measured resection surgical techniques for bicruciate-stabilized total knee arthroplasty. This indicates that both surgical techniques are safe and effective options for implanting this specific implant design.

Summary: The purpose of this study was to compare the effects of 'gap balancing' (GB) and 'measured resection' (MR) techniques on femoral component rotation (FCR) values in total knee arthroplasty (TKA). The results showed that after 2 years, TKA using the GB technique had better HSS patella scores, more external rotation in FCs, and higher PCO ratios. However, the difference in HSS patella scores was too small to be clinically significant, indicating that both GB and MR techniques can be used for FCR adjustment in clinical practice without hesitation.

Summary: This study developed a self-made tool for measuring and positioning the tibial osteotomy location before total knee arthroplasty (TKA) and evaluated its clinical effect. The use of self-made tools showed significant improvement in knee joint function and pain relief compared to the traditional method at a 5-year follow-up, indicating its potential to enhance the balance between flexion and extension gaps and overcome knee flexion instability during TKA.

Summary: This study describes a technique for femoral component rotation in total knee arthroplasty using a tibia-first, gap-balancing, functional alignment approach. The results show that this technique allows for appropriate femoral rotation without resulting in patellar maltracking.

Summary: This study compared the postoperative change in joint line and posterior condylar offset after total knee replacement using two different techniques. The results showed that measured resection technique was superior in restoring joint line level compared to gap balancing technique, while both techniques were equal in terms of restoring posterior condylar offset.

Summary: This study evaluated the effect of unreachable osteophytes on gap changes following bony resection in robotic arm-assisted total knee arthroplasty. The results showed that the size of osteophytes was positively correlated with gap increases. Surgeons should plan a slightly tight medial extension gap for patients with osteophytes larger than 10 mm.

Summary: This study compared the effects of sensor-guided knee balancing and conventional gap balancing techniques on postoperative clinical outcomes and patient satisfaction in TKA. The results showed that the sensor-guided group had better knee balance, but there was no significant difference in clinical outcomes and patient satisfaction between the two groups at 1 year postoperatively.

Summary: This study compared the imaging and clinical outcomes of the measured resection (MR), gap balancing (GB), and hybrid techniques in primary total knee arthroplasty. The results showed no significant differences in mechanical alignment or component positions among the three techniques. The hybrid technique was more helpful in maintaining the original height of the joint line.

Summary: This study compared the accuracy of soft tissue balancing using surgeon-defined assessment (SDA), a gap-balancer (GB), and an electronic sensor. The results showed that the GB was more accurate than the sensor in certain angles.

Summary: Both the measured resection and gap balancing techniques in total knee arthroplasty using the Attune(R) Knee System resulted in comparable functional and quality of life outcomes up to 2 years post-surgery. Both techniques appear to be equally effective in achieving excellent outcomes.

Summary: The study compared the rotational angle of the femoral and tibial components and the femorotibial rotational mismatch between the measured resection (MR) and gap-balancing (GB) techniques combined with a self-aligned technique. The results showed that the femoral component of the GB group had a greater degree of external rotation, but there was no significant difference in tibial rotational alignment or rotational mismatch between the two groups.

Summary: The study aimed to investigate the impact of knee position at tourniquet inflation on gap measurement during total knee arthroplasty. The results showed that the knee position, whether at flexion or extension, did not affect the gap measurement, indicating that it is feasible to measure the gap without considering knee position at tourniquet inflation.

Summary: This study aimed to investigate the effect of severe varus deformity on soft tissue balance in total knee arthroplasty (TKA). The results showed that the flexion and extension gap differences were significantly larger in the severe varus deformity group compared to the mild varus deformity group. The HKA varus angle was positively correlated with both gap differences and was an influencing factor for them.

Summary: This study compared the medial preserving gap technique (MPGT) with the measured resection technique (MRT) in terms of postoperative knee stability after posterior-stabilized total knee arthroplasty (PS-TKA). The results showed that MPGT provided better postoperative medial knee stability, especially at 3 years after PS-TKA.
