Article Abstract
Background: Existing systematic reviews have sought to characterize the relative donor-site morbidity of bone-patellar tendon-bone (BTB) and quadriceps tendon (QT) grafts after anterior cruciate ligament reconstruction (ACLR). However, no studies have reported the pooled proportions of patellar fractures and donor tendon ruptures across the body of literature.
Purpose: To estimate the proportion of patellar fractures, patellar tendon ruptures, and QT ruptures associated with BTB or QT autograft harvest during ACLR using published data.
Study Design: Systematic review; Level of evidence, 4.
Methods: A meta-analysis was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using 3 online databases (PubMed, Scopus, and Web of Science). A total of 800 manuscripts were included in the initial research of peer-reviewed articles in English that reported extensor mechanism complications associated with graft harvest in patients after ACLR. Pooled proportions of patellar fractures, patellar tendon ruptures, and QT ruptures were calculated for each graft type (BTB, QT) using a random-effects model for meta-analysis.
Results: A total of 28 studies were analyzed. The pooled proportion of patellar fractures was 0.57% (95% CI, 0.34%-0.91%) for the BTB harvest and 2.03% (95% CI, 0.78%-3.89%) for the QT harvest. The proportion of patellar tendon ruptures was 0.22% (95% CI, 0.14%-0.33%) after the BTB harvest, and the proportion of QT ruptures was 0.52% (95% CI, 0.06%-1.91%) after the QT harvest. The majority of included studies (16/28 [57.1%]) had an evidence level of 4.
Conclusion: Based on the current literature, the proportion of extensor mechanism complications after ACLR using either a BTB or a QT autograft is low, indicating that the extensor mechanism harvest remains a safe option. A higher proportion of patellar fractures was noted for QT grafts and a higher proportion of donor tendon ruptures was noted for QT grafts compared with BTB grafts.

Purpose: Slope-reducing high tibial osteotomies (SR-HTOs) correct posterior tibial slope (PTS) abnormalities in patients with anterior knee instability, as in cases of anterior cruciate ligament (ACL) deficiency. The SR-HTO techniques, including infra-tubercle and retro-tubercle approaches, provide distinct benefits: retro-tubercle techniques help preserve patellofemoral joint mechanics, while infra-tubercle techniques are effective in mitigating iatrogenic varus. However, there is limited comparative literature available.

Patellofemoral arthroplasty (PFA) is useful and effective option for treating patients with isolated patellofemoral osteoarthritis. The concept of functional positioning (FP) in PFA focuses on resurfacing the trochlea and restoring normal patellar tracking, while keeping the joint anatomy and kinematics. Even though the patellar liner cannot yet be placed with robotic assistance, robotic tools still help surgeons manage and optimize patellar tracking during surgery.

Purpose: Patella fractures are common and may result in significant morbidity. Open patellar fractures are less common, and there are few investigations into their outcomes and complications. This study aimed to determine acute outcomes after operative treatment of open versus closed patella fractures.

Introduction: The optimal fixation technique for patellar components in primary total knee arthroplasty (TKA); cemented versus press-fit, remains controversial. While early press-fit designs were associated with complications, second-generation implants with improved osseointegration features have renewed interest in cementless fixation.
Methods: This systematic review included studies comparing cemented and press-fit patellar fixation in primary TKA.

Aims: Our study explores the candy box (CB) technique with sutures and Nice knot as a novel treatment for inferior pole patellar fractures, potentially superior to traditional wire fixation.
Methods: CT data from five adult knee joints were extracted to create finite element models for inferior pole patellar fractures and four internal fixation models. These included CB technique combined with high-strength sutures and Nice knot (CB-H), CB technique combined with tendon sutures and Nice knot (CB-T), CB technique combined with steel wires (CB-S), and tension-band wiring combined with cerclage wiring (TBWC).
