Comparable postoperative outcomes in patients treated with either open or arthroscopic trochleoplasty for patella dysplasia.

Background: The aim of this study was to compare the clinical and radiologic results of the arthroscopic and the open trochleoplasty techniques.

Methods: A total of 83 trochleoplasties in 83 patients were performed between 2014 and 2021 in one institution. Surgical indications for trochleoplasty were recurrent patellofemoral instability and a lateral trochlear inclination angle (LTI) ≤ 11˚ and a trochlear depth ≤ 6 mm.

Tunnel widening after ACL reconstruction with different fixation techniques: aperture fixation with biodegradable interference screws versus all-inside technique with suspensory cortical buttons. 5-year data from a prospective randomized trial.

Background: The aim of the present study was to examine tunnel widening and clinical outcomes after anterior cruciate ligament reconstruction (ACLR) using two different fixation methods: aperture fixation with biodegradable interference screws versus all-inside ACLR with suspensory cortical buttons.

Methods: Tunnel widening was assessed using volumetric and diameter measurements on magnetic resonance imaging (MRI) scans directly after surgery, as well as 6 months and 2 and 5 years postoperatively. Clinical outcomes were assessed after 5 years with instrumented tibial anteroposterior translation measurement (KT-1000), single-leg hop testing, and the IKDC, Lysholm, and Tegner activity scores.

Reduction of Phantom Limb Pain and Improved Proprioception through a TSR-Based Surgical Technique: A Case Series of Four Patients with Lower Limb Amputation.

Four patients underwent targeted sensory reinnervation (TSR), a surgical technique in which a defined skin area is first selectively denervated and then surgically reinnervated by another sensory nerve. In our case, either the area of the lateral femoral cutaneous nerve or the saphenous nerve was reinnervated by the sural nerve. Patients were then fitted with a special prosthetic device capable of transferring the sense of pressure from the sole of the prosthesis to the newly wired skin area.

ACL reconstruction with adjustable-length loop cortical button fixation results in less tibial tunnel widening compared with interference screw fixation.

Purpose: To compare tunnel widening and clinical outcome after anterior cruciate ligament reconstruction (ACLR) with interference screw fixation and all-inside reconstruction using button fixation.

Methods: Tunnel widening was assessed using tunnel volume and diameter measurements on computed tomography (CT) scans after surgery and 6 months and 2 years later, and compared between the two groups. The clinical outcome was assessed after 2 years with instrumented tibial anteroposterior translation measurements, hop testing and International Knee Documentation Committee (IKDC), Lysholm and Tegner activity scores.

High complication rate following dynamic intraligamentary stabilization for primary repair of the anterior cruciate ligament.

Purpose: New strategies for dynamic intraligamentary stabilization (DIS) in the primary repair of anterior cruciate ligament (ACL) ruptures are currently under debate. It has been proposed that these might serve as alternative techniques to conventional ACL reconstruction procedures using tendon autografts. The aims of the present investigation were to evaluate the functional results and critically assess the complication rate following primary ACL repair with DIS and to review existing reports of favourable clinical results with the method in relation to knee joint stability and patient satisfaction.

Screw oversizing for anterior cruciate ligament graft fixation in primary and enlarged tibial tunnels: A biomechanical study in a porcine model.

Background: Ideal diameter for tibial interference screw fixation of the anterior cruciate ligament (ACL) graft remains controversial. Tibial graft fixation with screws matching the tunnel diameter vs. one-millimetre oversized screws were compared.

Tunnel widening after ACL reconstruction with aperture screw fixation or all-inside reconstruction with suspensory cortical button fixation: Volumetric measurements on CT and MRI scans.

Background: Tunnel widening after anterior cruciate ligament reconstruction (ACLR) is influenced by the surgical and fixation techniques used. Computed tomography (CT) is the most accurate image modality for assessing tunnel widening, but magnetic resonance imaging (MRI) might also be reliable for tunnel volume measurements. In the present study tunnel widening after ACLR using biodegradable interference screw fixation was compared with all-inside ACLR using button fixation, with tunnel volume changes being measured on CT and MRI scans.

Preparation techniques for all-inside ACL cortical button grafts: a biomechanical study.

Purpose: Performing all-inside anterior cruciate ligament reconstruction using cortical button fixation, the tendon graft has to be secured in a closed loop with sutures. In the present study, the graft secured with four sutures was compared with two reduced-suture material graft preparation techniques.

Methods: A bovine tendon graft folded over two adjustable-length loop cortical button devices was secured using the following techniques: 1, four buried-knot sutures; 2, two sutures on the tibial end only; and 3, two sutures on the tibial graft end with additional suspension on the tibial cortical button.

Elastic stable intramedullary nailing is best for mid-shaft clavicular fractures without comminution: results in 60 patients.

Introduction: Elastic stable intramedullary nailing (ESIN) of displaced mid-shaft clavicular fractures is a minimally invasive technique which was reported to be an easy procedure with low complication rates, good cosmetic and functional results, restoration of clavicular length and fast return to daily activities. Recent studies, however, also report on higher complication rates and specific problems with the use of this technique. This prospective study compares ESIN with non-operative treatment of displaced mid-shaft clavicular fractures.

Corrective osteotomy in symptomatic midshaft clavicular malunion using elastic stable intramedullary nails.

Introduction: It is our goal to present an alternative, less invasive surgical technique for corrective osteotomy in symptomatic midshaft clavicular malunion using elastic stable intramedullary nails (ESIN) and to present our results in a consecutive patients series.

Method And Patients: Between January 2003 and December 2006, five patients aged between 23 and 44 years presented with a symptomatic malunion after nonoperative treatment of displaced midshaft clavicular fractures. Corrective osteotomy was performed without bone grafting.

Real-time sonoelastography findings in healthy Achilles tendons.

Objective: Real-time sonoelastography is a new ultrasound-based technique able to assess tissue elasticity that has already shown feasibility in tumor diagnosis. The aim of this study was to assess the performance of real-time sonoelastography in depicting the Achilles tendons of healthy volunteers and to compare sonoelastography findings with conventional ultrasound findings.

Materials And Methods: Eighty asymptomatic Achilles tendons of 40 healthy volunteers (19 men, 21 women; mean age, 38 years; range, 20-76 years) were examined on real-time sonoelastography and ultrasound.

Radiological radio-carpal and mid-carpal motion after operative treatment of dorsal radio-carpal fracture dislocations.

Purpose: Radio-carpal fracture dislocations are rare severe injuries typically seen following high energy trauma. This injury is characterized by complete dislocation of the radio-carpal joint with avulsion fracture of dorsal or palmar cortical rim of the distal radius combined with disruption of the radio-carpal ligament complex. The purpose of our study is to assess the radiological motion outcome of the radio-carpal joint after Moneim type 1 radio-carpal fracture dislocations following surgical treatment.

Design: The study was a randomized, controlled, clinical trial.

Setting: Level 1 trauma center.

Shaft fractures of the clavicle: current concepts.

Fractures of the clavicle are common and have been typically addressed to nonoperative treatment. Favorable results, which predominantly were achieved in the young and adolescents, were supposed to be usual in midshaft clavicular fractures. However, in the presence of comminution or complete displacement, especially when occurring in females or elderly patients, there is a marked risk of nonunion, malunion, and poor outcome.

Severely comminuted bicondylar tibial plateau fractures in geriatric patients: a report of 2 cases treated with open reduction and postoperative external fixation.

We present 2 cases of C3-type fractures of the tibial plateau in geriatric patients. Our treatment concept--in particular the use of postoperative external fixation--is not yet described in the recent literature and includes initial external fixation, internal fixation after soft tissue consolidation using a median incision, filling of the metaphyseal comminution zone with allogenic cancellous bone obtained from a femoral head, anteromedial and anterolateral fixed-angle double plating, and external fixation postoperatively until osseous healing. The described treatment plan does not provide a valid alternative for the treatment of bicondylar fractures in younger patients.

Length determination in midshaft clavicle fractures: validation of measurement.

Objectives: To evaluate different methods of length determination in acute displaced midshaft clavicle fractures.
