Return to sport at the pre-injury level following anterior cruciate ligament reconstruction is influenced by patients' perceived knee status and psychological readiness, and does not correlate with functional ability.

Objectives: The purposes of this study were to (1) prospectively evaluate clinical and functional outcomes of athletes following anterior cruciate ligament (ACL) reconstruction up to 12 months after surgery, (2) to identify the correlations between functional and subjective tests, and (3) to determine which factors influence patients' capability to resume sports at pre-injury level.

Methods: Patients who underwent ACL reconstruction using doubled autologous hamstring graft were prospectively assessed pre-operatively, 6, and 12 months after surgery using International Knee Documentation Committee (IKDC) Subjective Knee Form, Tegner activity level, and ACL-Return to Sport after Injury (ACL-RSI) scale. Jumping ability was instrumentally assessed using a test battery including bipodalic squat jump (SJ), bipodalic countermovement jump (CMJ), monopodalic CMJ, and monopodalic side-hop test.

Limb asymmetries persist 6 months after anterior cruciate ligament reconstruction according to the results of a jump test battery.

Objectives: Test batteries used to assess a patient's return-to-sports (RTS) following anterior cruciate ligament reconstruction (ACLR) are currently undergoing continual development, although no consensus exist on tests to be administered to athletes before allowing return to play. A simple standardized jump test battery was developed to objectively evaluate knee function following ACLR, thereby aiding in RTS decision-making.

Methods: Thirty-three patients who underwent ACLR were prospectively assessed pre-operatively, 6, and 12 months after surgery.

This study compares the subjective, radiological, and functional results of total knee replacement (TKR) vs. combined medial unicompartmental knee replacement (UKR) with ACL reconstruction.

IELSG38: phase II trial of front-line chlorambucil plus subcutaneous rituximab induction and maintenance in mucosa-associated lymphoid tissue lymphoma.

Fracture of a polyethylene insert in a knee prosthesis is an uncommon but severe complication resulting in an unstable and malfunctioning knee that requires revision surgery. The aim of this paper was to present our experience with a minimally-invasive option for retrieving a posteriorly-migrated fragment of a mobile tibial bearing, which is a rare complication. We describe the management of a case of breakage of an Oxford knee medial bearing.

Drop Jump Performance Improves One Year Following Anterior Cruciate Ligament Reconstruction in Sportsmen Irrespectively of Psychological Patient Reported Outcomes.

Our study aims to prospectively report the functional outcomes of 31 sportsmen following anterior cruciate ligament (ACL) reconstruction, up to 12 months after surgery, with regards to subjective tests and drop jump performance, and to investigate the correlations between these variables, to be used for determining the return to sports after ACL reconstruction. Lysholm score, Tegner activity level, and the ACL-Return to Sport after Injury (ACL-RSI) scale were evaluated preoperatively, at 6 months, and at 12 months after surgery. Drop vertical jump was recorded using an infrared optical acquisition system.

Background: A growing number of physically active patients undergoing total knee replacement (TKR) desires to resume their preoperative activity levels and to be able to engage in sports after surgery. The purpose of this study was to assess the sporting and physical activities of patients who had undergone TKR. It was hypothesized that the majority of patients treated by TKR would have been able to return to amateur sports and recreational activity .

Management of isolated anterior talofibular ligament lesion in patients suffering from chronic ankle instability: comparison of two minimally invasive surgical techniques.

Objective: The aim of the present study was to retrospectively compare the outcomes of two minimally invasive surgical techniques in patients with isolated anterior talofibular ligament (ATFL) lesion suffering from chronic ankle instability (CAI).

Patients And Methods: Thirty-six patients with ATFL lesion suffering from CAI were treated at our department from 2010 to 2017 and retrospectively reviewed after an average time of 4 years (2 to 9 years). Eighteen patients underwent a four-step operative protocol, including: synovectomy, debridement of ATFL lesion borders, capsular shrinkage, and 21-day immobilization and non-weightbearing.

Does the Association of Microfractures for the Treatment of Osteochondral Lesions of the Talus Affect the Outcome Following Arthroscopic Treatment for Chronic Ankle Instability?

Background: The purpose of the present study was to retrospectively compare the outcomes of patients who underwent arthroscopic thermal capsular shrinkage with those who underwent both arthroscopic thermal capsular shrinkage and arthroscopic osteochondral lesion (OCL) treatment with microfractures. Our hypothesis was that the simultaneous treatment does not negatively affect the outcome of the combined surgical procedure by influencing the postoperative rehabilitation protocol and does not significantly differ from capsular shrinkage alone in terms of subjective and objective outcomes.

Methods: Seventy-six patients with chronic ankle instability were treated at our department from 2004 to 2012 and reviewed retrospectively.

The association of extra-articular tenodesis restores rotational stability more effectively compared to contralateral hamstring tendon autografts ACL reconstruction alone in patients undergoing ACL revision surgery.

Background: Recent years have seen a resurgence of interest about lateral extra-articular procedures performed in association with anterior cruciate ligament (ACL) surgery, as they can reduce the positivity to pivot shift test by acting on rotational instability. The purpose of the present study is to compare the postoperative functional outcomes of ACL revision surgery using contralateral hamstring tendon autografts with or without extra-articular tenodesis.

Hypothesis: The hypothesis is that combined extra-articular tenodesis gives better rotational stability following revision ACL surgery.
