Microfracture With Platelet Rich Plasma Gel Injection for Osteochondral Lesion of the Talus

Not Applicable
Recruiting
Conditions
Osteochondral Lesion of Talus
Microfractures
Platelet Rich Plasma
Registration Number
NCT06358807
Lead Sponsor
Peking University Third Hospital
Brief Summary

The goal of this clinical trial is to learn if combined local injection of platelet rich plasma (PRP) gel adds clinical efficacy to isolated arthroscopic microfracture in treatment of osteochondral lesion of the talus (OLT). The interface integration of the injured area will also be assessed via radiographic follow-up. The main questions it aims to answer are:

* Does arthroscopic microfracture combined with PRP gel injection improve ankle function of participants based on American Orthopedic Foot and Ankle Society (AOFAS) Score?

* Does arthroscopic microfracture combined with PRP gel injection improve interface integration of the injured cartilage on magnetic resonance imaging (MRI)? Researchers will compare arthroscopic microfracture with concomitant local injection of PRP gel to isolated microfracture to see if intraoperative PRP gel injection adds clinical efficacy to isolated arthroscopic microfracture in treatment of OLT.

Participants will:

* Undergo either isolated arthroscopic microfracture or microfracture with intraoperative injection of PRP gel

* Receive clinical follow-up 3, 6, 12, and 24 months after surgery and answer scales of ankle function assessment

* Take MRI preoperatively and 6, 12 and 24 months after surgery

Primary Outcome Measures
NameTimeMethod
American Orthopedic Foot and Ankle Society Score (AOFAS)Pre-surgery and 3, 6, 12 and 24 months after surgery

The scale of AOFAS score will be answered by participants during clinic follow-up preoperatively, and 3, 6, 12 and 24 months after surgery. The primary outcome measure will be the AOFAS collected 24 months post-surgery.

Secondary Outcome Measures
NameTimeMethod
Patient SatisfactionFinal follow-up (24 months after surgery)

Patient satisfaction will be graded as 0-10 and collected 24 months after surgery.

Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART)Twelve and 24 months after surgery

MOCART score will be assessed on magnetic resonance imaging 12 and 24 months after surgery.

Return-to-Sport RateFinal follow-up (24 months after surgery)

The rate and time point of participants returning to sports will be continuously followed during clinic follow-up and will be overall collected 24 months after surgery.

Foot and Ankle Outcome Score (FAOS)Pre-surgery and 3, 6, 12 and 24 months after surgery

The scale of FAOS score will be answered by participants during clinic follow-up preoperatively, and 3, 6, 12 and 24 months after surgery.

Ankle Activity Score (AAS)Pre-surgery and 3, 6, 12 and 24 months after surgery

The scale of AAS score will be answered by participants during clinic follow-up preoperatively, and 3, 6, 12 and 24 months after surgery.

Visual Analogue Scale (VAS)Pre-surgery and 3, 6, 12 and 24 months after surgery

The scale of VAS score will be answered by participants during clinic follow-up preoperatively, and 3, 6, 12 and 24 months after surgery.

ComplicationsFinal follow-up (24 months after surgery)

Complications, including infection,hematoma, stiffness, recurrent ankle pain will be continuously followed during clinic follow-up and will be overall collected 24 months after surgery.
