Summary: This study reviewed 10 articles investigating the outcomes of revision total knee and hip arthroplasty with the assistance of 3D printing. Most studies concluded that satisfactory clinical and radiological outcomes could be achieved with 3D printing in revision joint arthroplasty. Further long-term studies are needed to focus on cost-benefit analysis, resource availability, and the durability and biomechanics of customized prostheses using 3D printing.

Summary: This network meta-analysis compared the clinical and radiological outcomes of mechanically aligned total knee arthroplasty (MATKA), kinematically aligned TKA (KATKA), and restricted KATKA (rKATKA). The study found that while KATKA showed slight improvement in patient-reported outcome measures compared to MATKA, there was little difference in range of motion and revision risk between the three procedures. rKATKA, which focuses on reproducing normal knee anatomy, showed similar outcomes to KATKA.

Summary: This study investigated the relationship between changes in hip-knee-ankle (HKA) angle and hindfoot alignment after total knee arthroplasty (TKA) for varus knee osteoarthritis. The results showed that HFA was significantly adjusted by 3 months after TKA, and the change in HFA was weakly correlated with the change in HKA angle, with age impacting this correlation. In patients under 65 years old, there was a greater correlation between changes in HFA and HKA angle, while no correlation was observed in patients above 65 years old.

Summary: In this retrospective study involving 7 patients, revising stiff or unstable TKA from MA to KA resulted in improved range of motion by 30 degrees on averages, resolved instability without the use of constrained liners, improved clinical outcomes with a mean gain of 75 points on the KSS, and restored constitutional limb alignment within 2 degrees in all patients. Promising short term results warrant further study.

Summary: Semiautomated 3D measurements derived from weightbearing computed tomography (WBCT) scans were used to compare hindfoot alignment between healthy individuals and patients with progressive collapsing foot deformity (PCFD). Results showed differences in various measurements between the two groups, with TCA axial correlating with TNC in PCFD patients, and increased TCO combined with sinus tarsi/subfibular impingement raising the probability of predicting a deformity as rigid.

Summary: This study quantified the 3-dimensional ankle, hindfoot, and subtalar joint alignment after a solitary supramalleolar osteotomy. Alterations in the subtalar joint alignment, which occurred by 2 to 3 degrees in each anatomic plane, were found. Further studies on the variation of subtalar joint alignment change are needed before recommendations can be given related to inframalleolar procedures in conjunction to supramalleolar osteotomies.

Summary: Mechanical overload is the main cause of Achilles tendinopathy, and compressive loads may also contribute to the pathophysiology. However, data on intratendinous pressures is lacking. This study found that intratendinous pressure increased during stretching and eccentric loading, with the highest pressures in the deep insertion region and during the eccentric heel-drop. These findings suggest that compression plays a role in Achilles tendinopathy and further investigation is needed to explore its management in patients.

Summary: This study developed a multi-domain statistical shape model to assess morphologic and alignment variation of the subtalar, talonavicular, and calcaneocuboid joints. The results showed significant morphologic variation in the talus and calcaneus, while there was minimal shape variation in the navicular and cuboid. Alignment variations were mainly observed in the rotational aspect of the joints about the anterior-posterior axis.

Summary: The study evaluated the effects of muscle load on knee kinematics and stability after total knee arthroplasty (TKA), as well as the effect of TKA surgery on knee kinematics and stability. It also examined the correlation between stability in passive conditions and stability in active, muscle loaded conditions. The results showed that muscle force led to increased valgus and internal rotation of the femur, while TKA surgery resulted in more varus and external rotation. Muscle load and TKA implantation significantly reduced all laxities. The presence of the implant had a significant impact on active varus/valgus laxity, while passive laxity was the main determinant for rotational laxity. Passive laxity was also a significant predictor of active laxity for varus/valgus. In conclusion, knee stability is affected by muscle load, highlighting the importance of appropriate rehabilitation to prevent muscle atrophy. The functional, muscle loaded stability is strongly related to passive, ligament-based stability. Therefore, it is crucial to assess knee stability at the time of surgery, as passive laxity is the only predictor for functional stability in the operating theatre.
