The method using an osteoarticular allograft with a prosthetic composite is not new and has been discussed in a much larger series before [3]. We agree with Fan et al. that the described technique using a unicondylar osteoallograft prosthesis composite has not been described before. However, even if their article [4] is only a technical note, we think that the success of this method is not proven by the published short-term results. To exclude intermediate- and long-term complications (such as mechanical failure), a larger patient number with a longer followup is necessary.

We also are concerned about the high number of local recurrences in this case series. Analyzing the subgroups, there is a local recurrence rate of 33% in patients with h ...
