Container and system of containers of surgical instruments for knee surgery

1. A system of surgical instruments for use during a surgical procedure with a first implant and a second implant of the same type, but wherein the first implant and the second implant are of different sizes, the system comprising:

a first container containing at least a first surgical instrument of a first type that is size specific and a second surgical instrument of a second type that is size specific, wherein both the first and the second surgical instruments are of a first size corresponding to the first implant and the first and the second surgical instruments relate to preparation, finishing or trialing for the first implant;

a second container containing at least a third surgical instrument of the first type and a fourth surgical instrument of the second type, wherein both the third and the fourth surgical instruments are of a second size that is different from the first size and that corresponds to the second implant and the third and the fourth surgical instruments relate to preparation, finishing or trialing for the second implant; and

a third container containing at least a fifth surgical instrument of a third type that is size independent;

wherein the first, second, third, fourth and fifth surgical instruments are sterilized within their respective containers; and wherein the first and the second containers:

i) each contain only surgical instruments;

ii) each contain surgical instruments relating to the same stage in a surgical procedure; and

iii) each contain no other surgical instruments of the first type and the second type.

2. The system of claim 1 , wherein the fifth surgical instrument is for determining the required size of the first type of surgical instrument and/or the second type of surgical instrument.

3. The system of claim 1 for use in knee surgery, wherein the first and third instruments are a trial femoral implant, the second instruments are for performing femoral finishing resections suitable for the first trial femoral implant, and the fourth instruments are for performing femoral finishing resections suitable for the third trial femoral implant.

4. The system of claim 1 , wherein the first and second containers each contain:

a notch guide;

a femoral finishing cutting block;

a left trial femoral implant; and

a right trial femoral implant.

5. The system of claim 1 , wherein the first surgical instrument is a tibial trial instrument of a first thickness and is of the first size that corresponds to the first implant, the second surgical instrument is a tibial trial instrument of a second thickness and is of the first size that corresponds to the first implant, the third surgical instrument is a tibial trial instrument of the first thickness and is of the second size that corresponds to the second implant, and the fourth surgical instrument is a tibial trial instrument of the second thickness and is of the second size that corresponds to the second implant.

6. The system of claim 1 , wherein the first and second container contain instruments for femoral finishing and trial and the third container contains at least one of primary cuts instrumentation, core instrumentation, patella instrumentation and resection gap trialing/ligament tensing instrumentation.

7. The system of claim 6 , further comprising a fourth container and a fifth container containing instruments for tibial preparation and tibial trial.

8. The system of claim 1 , wherein the containers are disposable.

9. The system of claim 1 , wherein the containers are reusable.

10. The system of claim 1 , wherein the first container comprises a housing defining locations for the at least first and second surgical instruments and the second container comprises a housing defining locations for the at least third and fourth surgical instruments.
