Brief Summary:
The study is a randomized, prospective, multicenter, controlled clinical trial of the Episealer Knee System.The Episealer Knee System is intended for subjects with a focal femoral knee chondral or osteochondral lesion that is causing pain and/or disability and requires surgical treatment.

Condition or disease Intervention/treatment Phase
Degenerative Lesion of Articular Cartilage of Knee Device: Episealer Knee System Procedure: Microfracture Not Applicable

Detailed Description:

The primary objective of this study is to evaluate the safety and clinical effectiveness of the Episealer Knee System (Episealer Trochlea Solo, Episealer Femoral Twin, and Episealer Condyle Solo) compared to microfracture (with or without debridement) in a group of subjects that require repair of a focal femoral chondral or osteochondral lesion in the knee.

Clinical success will be analyzed via subject reported outcomes to measure function and pain improvements as compared to baseline, incidence of secondary surgical interventions for the treated knee, absence of subsidence or migration through radiographic assessment, and assessment of weight-bearing status.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 180 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: A total of 180 subjects will be enrolled and randomized using a 2:1 ratio (Episealer: Microfracture). Within each site, subjects will be randomized into one of the two study arms using a blocked randomization scheme with varying block sizes.
Masking: Single (Participant)
Masking Description: In this investigation, neither the investigator nor the subject can be blinded to the treatment group assignment due to the implant's distinctive form that can be detected on radiographs; however, the randomization assignment will not be disclosed to the subject until after surgery is performed.
Primary Purpose: Treatment
Official Title: A Prospective, Randomized, Controlled, Multi-Center Study to Evaluate the Safety and Effectiveness of the Episealer® Knee System Compared to Microfracture for the Treatment of Focal Femoral Knee Chondral or Osteochondral Lesions
Estimated Study Start Date : March 2020
Estimated Primary Completion Date : June 2022
Estimated Study Completion Date : June 2022

Arm Intervention/treatment
Experimental: Episealer Knee System
The experimental arm will comprise of subjects that will be treated with the Episealer Knee System.
Device: Episealer Knee System
The Episealer Knee System is comprised of individualized endoprosthetic resurfacing implants and implantation tools (Episealer Toolkit). The implants are designed to replace the articulating surface which has been damaged due to femoral knee chondral and osteochondral defects.

Placebo Comparator: Microfracture
The control arm will comprise of subjects that will receive a Microfracture surgery.
Procedure: Microfracture
Microfracture is a minimally invasive surgical technique developed to repair defects in articular cartilage and reduce pain in the knee joint. Microfracture techniques are described in the orthopedic literature and are performed arthroscopically.

    This endpoint will examine the incidence of Secondary Surgical Interventions (SSIs) at 24 months

  4. Incidence of subsidence or migration at 24 months [ Time Frame: 24 Months ]
    This endpoint will examine the incidence of subsidence/migration at 24 months

  5. Weight bearing status [ Time Frame: 8 weeks ]
    This endpoint will examine the weight bearing status at 8 weeks


Secondary Outcome Measures :
