Understanding Kinesiophobia: Predictors and Influence on Early Functional Outcomes in Patients with Total Knee Arthroplasty.

This observational study aimed to identify predictors of kinesiophobia and examine its correlation with early functional outcomes in TKA recipients. On the first and fifth postoperative days (POD1 and POD5), we evaluated pain using the International Pain Outcomes Questionnaire (IPO-Q) and created multidimensional pain composite scores (PCSs). The Total Pain Composite Score (PCStotal) assesses the overall impact of pain, taking into account outcomes of pain intensity, pain-related interference with function, and emotions and side effects.

Chronic post-surgical pain after knee arthroplasty: a role of peripheral nerve blocks.

Introduction: Peripheral nerve blocks are an efficient method of pain control after total knee arthroplasty (TKA), but there is no report of their impact on chronic post-surgical pain (CPSP).

Methods: This prospective observational study aimed to assess adductor canal block (ACB) and IPACK block (blocks vs. no blocks) on opioid consumption, postoperative pain score, chronic post-surgical pain 2 years after TKA.

The Influence of Platelet-Rich Fibrin on the Healing of Bone Defects after Harvesting Bone-Patellar Tendon-Bone Grafts.

: A bone-patellar tendon-bone (BTB) autograft in anterior cruciate ligament reconstruction (ACLR) is still considered the gold standard among many orthopedic surgeons, despite anterior knee pain and kneeling pain being associated with bone defects at the harvest site. Bioregenerative products could be used to treat these defects, perhaps improving both the postoperative discomfort and the overall reconstruction. : During a year-long period, 40 patients were enrolled in a pilot study and divided into a study group, in which bone defects were filled with Vivostat PRF (platelet-rich fibrin), and a standard group, in which bone defects were not filled.

Optimization of the "Perth CT" Protocol for Preoperative Planning and Postoperative Evaluation in Total Knee Arthroplasty.

: Total knee arthroplasty (TKA) has become the treatment of choice for advanced osteoarthritis. The aim of this paper was to show the possibilities of optimizing the Perth CT protocol, which is highly effective for preoperative planning and postoperative assessment of alignment. : The cross-sectional study comprised 16 patients for preoperative planning or postoperative evaluation of TKA.

The Influence of the Q-Angle and Muscle Strength on Idiopathic Anterior Knee Pain in Adolescents.

: Idiopathic anterior knee pain is a common condition in adolescents and is mostly of unknown cause. The aim of this study was to examine the influence of the Q-angle and muscle strength on idiopathic anterior knee pain. : Seventy-one adolescents (41 females and 30 males) diagnosed with anterior knee pain were included in this prospective study.

Rifampicin-induced fever during treatment against staphylococcal biofilm in a patient with periprosthetic joint infection.

Periprosthetic joint infection (PJI) after total knee arthroplasty remains a challenging complication. The treatment options for PJI include different procedures; however, regardless of the strategy, antibiotics are required. The combination of different antibiotics increased the rates of PJI eradication.

The first case of septic arthritis of the knee caused by Eggerthia catenaformis.

Eggerthia catenaformis has been reported as a human pathogen. We present the first case of the primary knee infection caused by Eggerthia catenaformis in a 23-year-old male patient with a knee infection, after primary anterior cruciate ligament reconstruction. Eggerthia catenaformis was confirmed by MALDI-TOF mass spectrometry from synovial fluid.

Associations between early postoperative pain outcome measures and late functional outcomes in patients after knee arthroplasty.

Introduction/aim: Early rehabilitation, return to daily life activities and function are the ultimate goals of perioperative care. It is unclear which pain-related patient-reported outcome measures (PROM) mirror treatment effects or are related with early and late functional outcomes.

Methods: We examined associations between two approaches of pain management (scheduled vs 'on demand') and PROMs on post-operative days one and five (POD1, 5) with function on POD5 and 3 months after surgery in patients undergoing Total Knee Arthroplasty (TKA) in a single centre.

Incidence and Risk Factors of 30-Day Surgical Site Infection after Primary Total Joint Arthroplasty in a Middle-Income Country: A Single-Center Experience.

The data about the incidence and risk factors for surgical site infections (SSIs) following total joint arthroplasty (TJA) in middle-income countries are still scant. The aim of this study was to assess the incidence and risk factors associated with 30-day SSIs following total hip arthroplasty (THA) and total knee arthroplasty (TKA). The study was conducted at the Clinic for Orthopedic Surgery and Traumatology, Clinical Center of Serbia (CCS) in Belgrade, from May 2016 to April 2018.

Instrumental Activities of Daily Living-A Good Tool to Prospectively Assess Disability after a Second Contralateral Hip Fracture?

Unlabelled: The aim of this study was to determine the outcome for patients who sustain a second hip fracture compared with those who sustain a first fracture, and to define the optimal measure to evaluate functional outcome after second hip fracture.

Methods: 343 patients with acute hip fractures who presented during a 12 month period were included in the study. Patients with a first (318 patients, 78.

Simultaneous Hip and Distal Radius Fractures-Does It Make a Difference with Respect to Rehabilitation?

Introduction: A minority of patients with hip fractures sustain concomitant wrist fractures. Little is known about the rehabilitation outcome in this group of patients.

Aim Of Study: Prospective investigation of functional outcome and survival in patients with combined hip and wrist fractures compared with patients who sustain an isolated hip fracture.

Can early assessment of hand grip strength in older hip fracture patients predict functional outcome?

Decreased muscle strength is not only a risk factor for hip fracture in older patients, but plays a role in recovery of physical function. Our aim was to assess the role of grip strength measured early after hip fracture, and classified according to the EWGSOP2 criteria in predicting short- and long-term functional recovery. One hundred ninety-one patients with acute hip fracture consecutively admitted to an orthopaedic hospital have been selected.

The effect of anterior cruciate ligament reconstruction on hamstring and quadriceps muscle function outcome ratios in male athletes.

Introduction: Maximal strength ratios such as the limb symmetry index (LSI) and hamstring-to-quadriceps ratio (HQ) may be considered the main outcome measures in the monitoring of recovery after anterior cruciate ligament (ACL) reconstruction. Although explosive strength is much more important than maximal strength, it is generally disregarded in the follow-up of muscle function recovery.

Objective: The purpose of this study was to compare ratios between maximal (Fmax) and explosive strength (rate of force development--RFD) in individuals with ACL reconstruction.

Contralateral limb deficit after ACL-reconstruction: an analysis of early and late phase of rate of force development.

The aim of this study was to assess the effect of a unilateral anterior cruciate ligament reconstruction (ACLR) on maximum voluntary contraction (MVC) and explosive strength of both the involved limb and the uninvolved limb. Nineteen male athletes completed a standard isometric testing protocol 4 months post-ACLR, while 16 healthy participants served as a control group (CG). The explosive strength of the knee extensors and flexors was assessed as RFD obtained from the slope of the force-time curves over various time intervals.

Microsurgical anatomy of the extra-articular segment of middle genicular artery.

Purpose: Knowledge of the incompletely studied microsurgical anatomy of the extracapsular part of the middle genicular artery (MGA) could imply an educational value and clinical significance because of the possible risk of injury during knee surgery.

Methods: Thirty formol-fixed cadaveric lower limbs in full extension were dissected and used for the measurements of MGA parameters. A second group of measurements was performed on distal ends of 30 adult femurs.

Length of the femoral tunnel in anatomic ACL reconstruction: comparison of three techniques.

Purpose: The aim of this paper was to determine whether the change in the position of the patient's leg as well as the use of flexible reamers may help in obtaining a longer femoral tunnel with minimal risk of perforating the posterior cortex.

Methods: One hundred and twenty-five patients who had undergone anatomic ACL reconstruction between 2010 and 2013 were included in this prospective cohort study. The first group was composed of patients whose femoral tunnel had been drilled with rigid reamers, while the leg being operated on was positioned on an arthroscopic leg holder (82 patients).

Giovanni Battista Monteggia (1762-1815).

Giovanni Battista Monteggia was born in Laverne on the 8th of August 1762. Monteggia started his education in the School of Surgery at the Hospital Maggiore in Milano in 1779.This hospital was called "Big House"and it is one of the oldest medical institutions in Italy.

Early mortality after hip fracture: what matters?

Background: Hip fractures in the elderly are followed by increased mortality, which is highest in the period immediately after the fracture. Predictors for early mortality have neither been well identified nor summarized. Identification of early postoperative mortality predictors enables the stratification of high-risk patients and can help in the development of strategies aimed at reducing risk and improving outcome after hip fracture.

Anatomic description of the anterolateral ligament of the knee.

Purpose: The anterolateral ligament, a structure that has been known for 130 years, has again attracted the attention both of orthopaedic doctors and anatomists. Since its initial description until now, this structure has had different names. Whether labelled as the mid-third lateral capsular ligament, the anterior oblique band of the fibular collateral ligament or the anterolateral ligament of the knee, this structure has been responsible for the so-called Segond avulsion fractures.

The influence of sex hormones on anterior cruciate ligament ruptures in males.

Purpose: The purpose of this study is to determine the difference in the concentrations of testosterone, 17-β estradiol and progesterone between male patients with and without ACL rupture, as well as the possible effect of these hormones on generalized joint laxity.

Methods: Male subjects with non-contact knee joint injury were included in this study. Two groups were formed: the examined group, consisting of subjects with ACL rupture and the control group consisting of patients without ACL rupture.

Asymmetries in explosive strength following anterior cruciate ligament reconstruction.

Background: Despite its apparent functional importance, there is a general lack of data regarding the time-related changes in explosive strength and the corresponding side-to-side asymmetries in individuals recovering from an ACL reconstruction (ACLR). The present study was designed to assess changes in the maximum and explosive strength of the quadriceps and hamstring muscles in athletes recovering from an ACLR.

Methods: Twenty male athletes with an ACL injury completed a standard isometric testing protocol pre-ACLR, four and sixmonths post-ACLR.

The influence of sex hormones on anterior cruciate ligament rupture: female study.

Purpose: The purpose of this study was to determine the difference in the concentrations of testosterone, 17-β estradiol and progesterone between female patients with and without ACL rupture and the possible effect of these hormones on generalised joint laxity.

Methods: Female subjects with non-contact knee joint injury were included in this study. They were divided into two groups: the examined group, consisting of female subjects with ACL rupture, and the control group, consisting of female patients without ACL rupture.

Morphometric parameters as risk factors for anterior cruciate ligament injuries - a MRI case-control study.

Background/aim: The anterior cruciate ligament (ACL) is the most frequently injured ligament of the knee, representing 50% of all knee injuries. The aim of this study was todeter mine the differences in the morphometry of knee injury patients with an intact and a ruptured anterior cruciate ligament.

Methods: The study included 33 matched pairs of patients divided into two groups: the study group with the diagnosis of anterior cruciate ligament rupture, and the control group with the diagnosis of patellofemoral pain but no anterior cruciate ligament lesion.

Evaluation of isokinetic and isometric strength measures for monitoring muscle function recovery after anterior cruciate ligament reconstruction.

Although various strength tests and their outcome measures have been proposed for anterior cruciate ligament (ACL) reconstruction (ACLR), their measurement properties still remain relatively underexplored. The aim of this study was to investigate the longitudinal construct validity of the standard isokinetic (IKT) and isometric test (IMT), and of the IMT of alternating consecutive maximal contractions (ACMC). In addition, the concurrent validity of ACMC was assessed and compared with the validity of IMT.
