3-Year Clinical Result of a Customized Metal Mini-Prosthesis for Focal Chondral Lesion in The Knee Of A Formerly Active 31-Year-Old Man.

“…The patient had been out of work as a carpenter for almost 2 years and was at risk of losing his ability to work completely and becoming a heavy financial burden on society. We know from other studies [6,7,8,10] -that the loss of working ability can be fatal for such patients, who are still of working age, and the economic costs for society enormous, especially for these patients in the "Treatment Gap". In the US, 3.6 million patients with symptomatic knee-pain fall into this group [10].…”

“…The treatment of (osteo) Chondral lesions remains a clinical challenge. [1][2][3]6,7,8,16] A "gap" has been identified (9), where some patients with focal knee-lesions are considered too old for biological treatment or failed treatment, but too young for uni-or total arthroplasty (UKA/TKA). In order to fill this gap, an innovative, patient-specific metal implant (Episealer) has been designed from MRI-images and the lesion-size, and ongoing CPL (Controlled Product Launch) is taking Place, with almost 2-year follow-up.…”

HemiCAP-Wave® Implant in Salvage Procedure of a Large Trochlea Lesion in the Knee in a 37 Year Old Former Active Man

“…The patient had been out of work as a physiotherapist for almost 3 years and was at risk of losing his ability to work completely and thereby becoming a heavy financial burden on society. We know from other studies [7][8][9][10] that the loss of working ability can be fatal for such patients, who are still of working age, and the economic costs for society enormous, especially for these younger patients in the "Treatment Gap", meaning patients between 35 and 60 years, where cartilage procedures such as ACI (autologous chondrocyte implantation, True Fit or microfracture technique is dubious, and jet not old or worn enough for a TKA. It is estimated that only in the US, 3.6 million patients with symptomatic knee-pain fall into this group [10].…”

“…The osteoarthritis (OA) grade at standard weight-bearing AP, axial and patellae-skyline radiographs was evaluated using the KellgrenLawrence scale (KL) [6] for both medial and lateral tibiofemoral compartments and the patellofemoral compartment preoperatively and at the clinical follow-up to investigate 34 OA development after surgery [7,8].…”

The clinical outcome of the different HemiCAP and UniCAP knee implants: A systematic and comprehensive review

“…12 Elderly patients with isolated patellofemoral arthritis can be treated with total knee replacement, a procedure which is generally not indicated for young patients. 13 …”
