Summary: This study investigated the feasibility of using pinless navigation for tibial component implantation in unicompartmental knee arthroplasty. The results showed that the pinless navigation technique and the conventional technique achieved similar results in positioning the tibial component, with negligible differences in surgical time.

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: Computer-assisted total knee arthroplasty (CAS) and conventional cTKA have similar functional, radiological, and complication outcomes. However, CAS surgery has a longer operation time and higher notching frequency and size compared to cTKA.

Summary: The study investigated femoral component alignment in patients undergoing soft tissue-guided, navigated TKA. Results showed that with a mechanically aligned tibial component and tensioned soft tissues, the femoral component was placed at an average of 1.7 degrees varus in the coronal plane, aligning with the preoperative distal femoral joint line. Satisfactory knee function and excellent pain relief were demonstrated postoperatively based on KOOS and KSS scores.

Summary: Surgeons with higher medial UKA usage have lower UKA revision rates but higher TKA revision rates. Overall, surgeons performing 1-5% UKA had the lowest TKA and combined UKA + TKA revision rates. However, there was no significant difference in OKS scores between different UKA usage groups.

Summary: The study examined the accuracy of ICD-10-PCS coding in computer-navigated and robotic THA, finding that 87.5% of technology-assisted THAs were coded correctly. The most common errors were the omission of technology codes in computer-navigated THA and the designation of both computer navigation and robotic assistance codes in robotic THA. Concerns were raised about the integrity and accuracy of ICD-10-PCS data, especially in data sets that rely exclusively on it for procedural granularity.

Summary: This study found that TKA resulted in inferior extensor function compared to UKA and BCA. This may, in part, help explain the reported differences in function and satisfaction differences between partial and total knee arthroplasty.

Summary: This study aimed to quantify the soft tissue tension of the medial compartment and determine if there is an optimal target tension value that matches the natural state. The results showed that MB-UKA surgery cannot accurately restore soft tissue tension to the natural state, and objective data from sensor output may assist surgeons in reducing loading variability.

Summary: This study assessed the effects of morbid obesity on patients undergoing UKA and TKA, and found that morbidly obese UKA patients had fewer medical complications and readmissions, but higher rates of mechanical loosening. Compared to TKA patients, UKA patients had shorter lengths of stay and lower costs. Morbidly obese UKA patients had similar complication rates and lower medical utilizations compared to TKA patients with a BMI <40.

Summary: This systematic review with meta-analysis found that delaying rotator cuff surgery for 3 to 6 months did not lead to higher retear rates or inferior patient-reported outcome measures (PROMs) as compared with undergoing earlier surgery. However, delaying surgery for >= 1 year clearly resulted in higher retear rates after rotator cuff repair. Larger prospective studies are needed to confirm these findings.

Summary: Combined injury of the anterior cruciate ligament (ACL) and medial collateral ligament (MCL) is a common knee injury pattern. The optimal treatment for grade III MCL injuries, especially when combined with ACL injury, is still debated. Delayed treatment of ACL-MCL injuries has disadvantages, including incomplete MCL healing, prolonged rehabilitation period, and increased risk of intra-articular damage. Simultaneous surgical treatment of both ligaments has the potential to avoid these shortcomings. This article reviews the evolution of treatment for ACL-MCL injuries and discusses the current treatment algorithm, its shortcomings, potential advantages of acute simultaneous treatment, and the available literature.

Summary: This study aimed to assess outcomes following total knee arthroplasty (TKA) in a large cohort with and without pain catastrophizing (PC). The study found that patients with PC had worse preoperative function and pain, but had more improvement at 6 months and 12 months postoperatively. However, at 24 months, PC patients reported more pain.

Summary: In the past decade, there have been various techniques proposed for preserving the anterior cruciate ligament (ACL), resulting in a resurgence of selective arthroscopic ACL preservation. These techniques involve different methods of suturing, fixation, and augmentation, but lack consideration for important anatomical and biomechanical properties. The aim of this technique is to anatomically reapproximate the anteromedial (AM) and posterolateral (PL) bundles of the ACL to their respective femoral footprints, while also performing a PL compression stitch to increase ligament-bone contact area and recreate the anatomic vectors of the native bundles. This minimally invasive procedure, which does not involve graft harvesting or tunnel drilling, has shown decreased pain levels, earlier return of full range of motion (ROM), and faster rehabilitation, with comparable failure rates to ACL reconstruction.

Summary: Many surgeons facing the challenge of harvesting small hamstring grafts during ACL reconstruction can consider several options, such as using contralateral hamstring tendons, reinforcing the ACL graft with allografts, utilizing a bone-patellar tendon-bone or quadriceps graft, or adding an anterolateral ligament reconstruction or lateral extra-articular tenodesis. Recent studies indicate that the presence of a lateral extra-articular procedure might be more crucial than the thickness of the isolated ACL graft, offering reassuring news. Current evidence suggests that both anterolateral ligament reconstruction and modified Lemaire tenodesis have similar biomechanical and clinical outcomes, providing potential solutions for small-diameter hamstring ACL autografts.

Summary: This paper presents a novel automatic method for the computation of glenoid bone loss in CT scans. The method consists of four steps: computation of an oblique plane, selection of the glenoid oblique CT slice, computation of the best-fit circle, and quantification of the bone loss. The evaluation results show that the method has a mean absolute error of 2.3±2.9 mm (4.67±3.32%) and can assist orthopedists in surgical planning.
