PURPOSE: The optimum treatment strategy for the surgical management of partial-thickness rotator cuff tears (PTRCT) is evolving. In this study, two research questions were sought to be answered: "Does the repair technique for PTRCTs involving >50% of the tendon thickness have an effect on structural and functional outcomes of arthroscopic repair?" and "Is there a difference in outcomes of arthroscopically treated articular- and bursal-sided PTRCTs?". METHODS: A systematic review according to the PRISMA statement was conducted to identify all literature published reporting on outcomes of arthroscopic treatment of PTRCTs classified with the Ellman classification with minimum 2-year follow-up...

PURPOSE: In total knee arthroplasty (TKA), the posterior tibial slope is not always reconstructed correctly, and the knee ligaments may become too tight in flexion. To release a tight flexion gap, surgeons can increase the posterior tibial slope using two surgical resection techniques: the anterior tibial cortex (ACR) or the centre of tibial plateau (CPR) referencing. It is not known how this choice affects the knee laxity and function during activities of daily living. The aim of this study was to investigate the effect of tibial slope on knee laxity, kinematics and forces during a squatting activity using computer simulation techniques...

PURPOSE: Patellofemoral osteoarthritis (PFOA) occurs in approximately half of anterior cruciate ligament (ACL)-injured knees within 10-15 years of trauma. Risk factors for post-traumatic PFOA are poorly understood. Patellofemoral alignment and trochlear morphology may be associated with PFOA following ACL reconstruction (ACLR), and understanding these relationships, particularly early in the post-surgical time period, may guide effective early intervention strategies. In this study, patellofemoral alignment and trochlear morphology were investigated in relation to radiographic features of early PFOA 1-year post-ACLR...

PURPOSE: Abnormal knee motion under various conditions has been described after total knee arthroplasty (TKA). However, differences in kinematics and kinetics of knees with varus femoral versus varus tibial alignment have not been evaluated. It was hypothesized that varus femoral and tibial alignments have the same impact on knee motion. METHODS: A musculoskeletal computer simulation was used. Femoral and tibial alignment in the coronal plane was each varied from neutral to 5° of varus in 1° increments...

PURPOSE: Graft choice for anterior cruciate ligament (ACL) reconstruction is crucial, however the optimal graft source remains a topic of controversy. The purpose of this study is to compare subjective and functional patient-reported outcomes (PRO) after single-bundle ACL reconstruction using quadriceps tendon (QT) or hamstring tendon (HT) autografts for single-bundle ACL reconstruction. We hypothesize that there is no difference in patient-reported functional outcomes after ACL reconstruction using either HT- or QT autograft...

PURPOSE: Simultaneous rupture of the patellar tendon (PT) and the anterior cruciate ligament (ACL) is a relatively rare injury. This study offers a comprehensive review of the published reports and presents two cases of simultaneous PT and ACL rupture. METHODS: A systematic review of English literature was performed, and data from two patients who were referred to our institution with simultaneous PT and ACL rupture were collected. Both patients underwent primary arthroscopic ACL reconstruction combined with PT reconstruction and, 1 year after surgery, magnetic resonance imaging (MRI), clinical examination, strength measurement and functional assessment...

PURPOSE: Symptomatic discoid lateral meniscus without tears has traditionally been treated with excision of part or the entire meniscus. Resection of 15-34% of the meniscus increases tibiofemoral contact pressures by more than 350%. Treatment of discoid lateral meniscus with partial or total meniscectomy in childhood increases the risk of early-onset osteoarthritis in the knee. The incidence of osteoarthritis is directly proportional to the amount of meniscal tissue resected. This paper describes the meniscus-preserving technique of meniscopexy and presents the outcomes of all patients who have undergone this procedure in the management of lateral discoid meniscus in a single unit over a 14-year period...
