Suitability of Minced Cartilage From Osteochondral Lesions of the Talus for Immediate Autograft Reimplantation.

Background: Particulated autograft cartilage implantation is a surgical technique that has been previously described for the repair of osteochondral lesions of the talus (OLT). It uses cartilage fragments harvested from the OLT that are minced into 1-2-mm fragments and then immediately reimplanted back into the chondral defect and sealed with fibrin glue during a single-stage surgery. The purpose of this study was to characterize the suitability of these minced cartilage fragments as immediate autograft for the treatment of OLTs.

Minimally Invasive Cheilectomy for Hallux Rigidus.

Hallux metatarsophalangeal joint cheilectomy is a joint-sparing technique that involves resection of the dorsal metatarsal head osteophytes; this may be achieved through minimally invasive and arthroscopic techniques. General indications for minimally invasive surgery (MIS) cheilectomy are mild-to-moderate hallux rigidus (Grades I-II) with symptomatic dorsal osteophytes causing dorsal impingement and/or shoe wear irritation in those who have failed extensive nonoperative management. The literature confirms equivalent outcomes to open cheilectomy; however, it is somewhat inconsistent regarding superiority.

The Effect of Tibiotalar Joint Line Level Alterations on Tibiotalar Range of Motion Following Total Ankle Arthroplasty.

Background: The effect of tibiotalar joint line level (TTJL) on patient outcomes following total ankle arthroplasty (TAA) remains unclear. It was previously reported that patients with end-stage ankle arthritis have an elevated TTJL compared with nonarthritic ankles, and the TTJL post-TAA remains elevated compared with nonarthritic ankles. The objectives of this study were to (1) propose a reliable radiographic method to measure the TTJL absolute value and (2) determine the effect of TTJL alterations on tibiotalar range of motion (ROM) following TAA.

Mild Synovitis Impairs Chondrogenic Joint Environment.

The impact of mild synovitis on the chondrogenic environment in the joint pertaining to cartilage repair is often neglected. In this study, 21 synovial samples were collected from foot surgeries for histology and isolation of fibroblast-like synoviocytes (FLSs). Of the 21 samples, 13 were normal and eight were mild synovitis, according to their synovitis scores.

Application of the Mayo Periprosthetic Joint Infection Risk Score for Total Ankle Arthroplasty.

Background: Assessing patient's risk of infection is fundamental for prevention of periprosthetic joint infection (PJI) after total ankle arthroplasty (TAA). The Mayo Prosthetic Joint Infection Risk Score (Mayo Score) is based on data from total hip and knee arthroplasty and has not been validated for application for TAA.

Methods: A total of 405 consecutive TAA cases were followed for 6 months for PJI.

Ankle Arthrodesis in Crippled Cases.

The current article provides an algorithm of how to approach crippled ankle by ankle arthrodesis. There is no standard pathology or treatment present, which makes the diagnosis but also surgical correction complex. A surgeon who faces this kind of deformities needs to be skilled and well familiar with the full setting of the foot and ankle armamentarium.

Increased synovial expression of calcitonin gene-related peptide and its potential roles in Charcot Neuroarthropathy.

Objective: Joint destruction in Charcot neuroarthropathy (CNA) is accompanied with abundant hyperplastic synovium. This study aimed to characterize the expression patterns of a group of neuropeptides in the CNA synovium.

Methods: Synovial specimens were collected during surgery from the CNA (n = 6) and non-CNA joints (n = 14).

Failed Cavovarus Reconstruction: Reconstructive Possibilities and a Proposed Treatment Algorithm.

This article provides an overview of the techniques and strategies to address a failed cavovarus deformity correction. These problems pose significant challenges to the treating surgeons and should be accurately planned before embarking on surgery.

The Current Status of Clinical Trials on Biologics for Cartilage Repair and Osteoarthritis Treatment: An Analysis of ClinicalTrials.gov Data.

Objective: Biologics are increasingly used for cartilage repair and osteoarthritis (OA) treatment. This study aimed to provide an overview of the clinical trials conducted on this subject.

Design: Two-word combinations of two sets of key words "cartilage"; "joint"; "osteoarthritis" and "biologics"; "stem cells"; "cell implantation" were used to search the database of ClinicalTrials.

Favorable Outcome Twenty-Two Months after Delbet Type Ib Capital Femoral Transepiphyseal Fracture and Posterior Column Acetabular Fracture in a Fifteen-Year-Old Male.
