Allegretto®
Product Information
According to the resurfacing philosophy, minimal bone loss is the key element of Allegretto MIS.
By combining a bone-preserving implant design with state-of-the-art operating instruments, Allegretto meets the requirements for a modern System for unicompartmental knee replacement in every respect.
Zimmer sets the standards for minimally invasive operation techniques and instruments.

Soft Tissue Balancing
Precise bone incisions are performed with the correct brace tension, as required by the patient’s current pathological situation.
Minimal bone resection
The Allegretto Femur Design is based on the natural shape of the femoral condyle. This keeps the quantity of bone which needs to be resected to a minimum.
The tibia implants are implanted without an anchoring mechanism, preserving bone. The necessary stability is achieved by means of an appropriate cementation technique.
Precise alignment – precise incisions
With the Allegretto MIS instrument set, every incision is “guided” by the appropriate instrument. This improves the reproducibility of optimal operation results.
Preservation of soft tissue
The minimal incision, together with the slender instruments, makes eversion of the patella during the operation unnecessary. The entire soft tissue apparatus can be preserved to the maximum possible extent during the operation.
Small wound incision
The length of the wound incision is related to the specific characteristics of the patient (e.g. height and weight).
The length of the resulting scar is a cosmetic concern for the patient which must not be underestimated. However, it is a mistake to use this as the only valid criterion and it must not compromise the quality of the operation result.
As a rule, operations can be performed with the Allegretto MIS instruments by means of an 8cm incision.
The patient is up and about again more quickly
The body of the patient is particularly protected during an operation with MIS technology. The hospitalization period of the patient is thus reduced from 7 to 10 days to approx. 2 to 3 days.*
* The postoperative protocol of the patient is the responsibility of the responsible physician in each case.
