## Abstract

Aspects disclosed herein may provide a method for determining a duration of a medical procedure. The method may include receiving imaging data including at least one image acquired of a patient's anatomy, determining at least one parameter of the patient's anatomy based on the imaging data, predicting a duration for the medical procedure based on the determined at least one parameter, and outputting the predicted duration on an electronic display. The at least one parameter may include at least one of a B-score, a joint-space width, an osteophyte position or volume, an alignment, or a deformity based on the imaging data.

predicting a duration for the medical procedure based on the determined at least one parameter; and
outputting the predicted duration on an electronic display.

The method of claim 1, further comprising:
identifying at least one femur in the at least one image, wherein the parameter includes a B-score of the identified femur;
determining that the B-score is greater than a predetermined B-score, and
determining that the predicted duration is longer or shorter than a predetermined duration.

### Claim 3 (depends on 1)

The method of claim 1, further comprising:
identifying at least two bones at a joint in the at least one image, wherein the parameter includes a joint-space width between the at least two bones; and
determining whether the joint-space width is within a predetermined joint-space width range.

### Claim 4 (depends on 3)

The method of claim 3, further comprising:
determining that the joint-space width is outside the predetermined joint-space width range, and
determining that the predicted duration is longer than a predetermined duration.

### Claim 5 (depends on 1)

The method of claim 1, further comprising:
identifying at least one bone in the at least one image; and
detecting at least one osteophyte on the identified at least one bone.

### Claim 6 (depends on 5)

The method of claim 5, further comprising:
determining a volume of the detected at least one osteophyte, and
determining that the predicted duration is longer or shorter than a predetermined duration based on the determined volume.

### Claim 7 (depends on 5)

The method of claim 5, wherein detecting at least one osteophyte on the identified at least one bone includes determining a position of the at least one osteophyte in relation to a predetermined area or compartment on the identified bone.

### Claim 8 (depends on 1)

The method of claim 1, further comprising:
identifying at least one bone in the at least one image;
determining an alignment parameter of the at least one bone; and
determining whether the alignment parameter is within a predetermined alignment range.

### Claim 9 (depends on 8)

The method of claim 8, further comprising:
determining that the alignment parameter is outside the predetermined alignment range, and
determining that the predicted duration is longer than a predetermined duration.

### Claim 10 (depends on 1)

The method of claim 1, further comprising:
receiving prior procedure data, the prior procedure data including data from a plurality of prior patients sharing at least one characteristic with the patient, wherein determining the predicted duration for the medical procedure is based on the received prior procedure data.

### Claim 11 (depends on 1)

The method of claim 1, further comprising:
receiving at least one of (i) patient specific data regarding the patient, (ii) clinical data relating to the patient, and (iii) surgeon specific data relating to one or more surgeons, wherein determining the predicted duration for the medical procedure is based on the received patient specific data, clinical data, and/or surgeon specific data.

### Claim 12 (depends on 1)

The method of claim 1, further comprising determining, based on the determined predicted duration for the procedure and/or the at least one parameter of the patient's anatomy, an output, the output including at least one of:
