Devices and systems for assessing laxity in a joint

A system for assessing laxity in a joint having a first bone and a second bone, the system comprising:

• a tensioner tool comprising a pair of arms defining an insertion portion, wherein the pair of arms are configured to pivot about a pivot axis between a compressed configuration and an expanded configuration;
• a trial component comprising:
• a base plate configured to couple to the first bone, and
• a superior spacer coupled to the base plate, wherein the superior spacer is configured to be selectively moved between a first position in contact with a superior surface of the base plate and a second position separated from the superior surface,
• wherein the base plate and the superior spacer define a cavity therebetween, the cavity configured to receive the insertion portion of the tensioner tool therein;
• a processor;
• and
• a non-transitory, computer-readable medium storing instructions that, when executed, cause the processor to:
• receive information related to a distance between the superior surface of the base plate and the superior spacer in the second position, and
• determine, based on the information, a gap distance associated with the first bone and the second bone.

A method of assessing laxity in a joint, the method comprising:

• applying a trial component to a first bone of the joint, the trial component comprising a base plate configured to couple to the first bone and a superior spacer coupled to the base plate;
• inserting an insertion portion of a tensioner tool within a cavity defined between the base plate and the superior spacer, the insertion portion comprising a pair of arms;
• separating the pair of arms, thereby causing the superior spacer to move from a first position in contact with a superior surface of the base plate to a second position spaced from the superior surface;
• and
• determining a first distance between the superior surface of the base plate and the superior spacer in the second position.
