PURPOSE: Adductor canal block has emerged as a favourable element of multimodal analgesia regimens for total knee arthroplasty, due to the exclusive sensory blockade it provides. However, it is controversial as to whether a single shot or continuous technique adductor canal block is superior. This meta-analysis examined the effect of both these techniques on pain management associated with total knee arthroplasty. METHODS: All randomised controlled trials published on Cochrane Library, PubMed, and EMBASE, Scopus, and PsychINFO were systematically searched...

INTRODUCTION: Prior studies have demonstrated an association between time to revision total knee arthroplasty (rTKA) and indication; however, the impact of early versus late revision on post-operative outcomes has not been reported. MATERIALS AND METHODS: A retrospective, observational study examined patients who underwent unilateral, aseptic rTKA at an academic orthopedic hospital between 6/2011 and 4/2020 with > 1-year of follow-up. Patients were early revisions if they were revised within 2 years of primary TKA (pTKA) or late revisions if revised after greater than 2 years...

BACKGROUND: Patients with severe obesity [body mass index (BMI) ≥ 40 kg/m2 ] potentially overload the tibial component after total knee arthroplasty (TKA), risking tibial subsidence. Using a cemented single-radius cruciate-retaining TKA design, this study compared the outcomes of two tibial baseplate geometries in patients with BMI ≥ 40 kg/m2 : standard keeled (SK) or universal base plate (UBP), which incorporates a stem. METHODS: This was a retrospective, single-centre cohort study with minimum 2 years follow-up of 111 TKA patients with BMI ≥ 40 kg/m2 : mean age 62...

BACKGROUND: Patients with partial medial meniscus posterior root tears (MMPRTs) sometimes require arthroscopic pullout repair because of their intolerable/repeated knee pains and continuous disturbance in gait during activities of daily living. However, the predisposing factors for future knee surgery in patients with partial MMPRTs remain unclear. We compared the findings of magnetic resonance imaging (MRI) between patients who underwent pullout repair and nonoperative management following partial MMPRTs...

The multifactorial origin of anterior knee pain in patellofemoral joint disorders leads to a demanding diagnostic process. Patellofemoral misalignment is pointed out as one of the main causes of anterior knee pain. The main anatomical risk factors of patellofemoral instability addressed in the literature are trochlear dysplasia, abnormal patellar height, and excessive tibial tubercle-trochlear groove distance. Diagnostic imaging of the patellofemoral joint has a fundamental role in assessing these predisposing factors of instability...

PURPOSE: To determine whether additional stem extension for stability is necessary, we performed mid-term follow-up of patients who had been managed with 5-mm metal block augmentation for a tibial defect, where tibial prosthesis was fixed using bone cement without stem extension. Also, we evaluated clinical and radiologic results including survival rate of patients without stem extension. METHODS: We retrospectively analyzed patients with tibial bone defect, had undergone primary total knee arthroplasty, and had been treated with 5-mm metal block augmentation without stem extension between March 2003 and September 2013...

Patient reported outcome measures (PROMs) are essential for clinical research and patient-centric care because they allow us to capture patient perspectives on their health condition. In knee arthroplasty, PROMs are frequently used to assess the risks and benefits of new interventions, surgical approaches, and other management strategies. A few examples of PROMs used in total knee arthroplasty (TKA) include the Oxford Knee Score (OKS), Knee Injury and Osteoarthritis Outcome Score (KOOS), and the Forgotten Joint Score (FJS) (collectively referred to as "legacy" PROMs)...

PURPOSE: Proximal tibia stress fractures present a challenge when performing total knee arthroplasty (TKA) in knee arthritis (KA). The literature on treatment modalities for stress fractures with arthritis is varied and not systematically reviewed. We aimed to answer the questions: (1) Is long-stem TKA sufficient for stress fractures in arthritic knees? (2) Should stress fracture and KA be addressed simultaneously? (3) What is the role of augmentative procedures in stress fractures with knee arthritis? (4) Can a unified algorithm be established? METHODS: The PubMed and Cochrane databases were searched for keywords such as stress fracture, knee arthritis and total knee arthroplasty, published from January 1995 to 29 May 2022...
