This study represents a single-surgeon/institution, non-randomized, consecutive series, prospective and comparative cohort design. The Principal Investigator is anticipating 100 study patients in the INTACT group and 35 patients in the Anterior Cruciate Ligament-Deficient group.The schedule of events lists the imaging procedures and questionnaires to be completed at each visit. Subjects will be consented and enrolled within 28 days prior to surgery and participate in follow-up visits for two years following their Unicompartmental Knee Arthroplasty. A 3-year enrollment duration is anticipated to enroll a minimum and consecutive series of 25 patients in the experimental Anterior Cruciate Ligament-deficient group. Over the same enrollment duration, 100+ patients with intact Anterior Cruciate Ligaments are expected to be in the control group and undergo Unicompartmental Knee Arthroplasty. The enrollment duration (3 years) and total study duration (5 years) are based on patient volume estimates provided by the Principal Investigator.

Functional and Clinical Outcomes comparing patients with and without intact Anterior Cruciate Ligaments undergoing arthroplasty with MAKO Robotic-Arm Assisted Surgery.
Timeframe: Baseline (screening), compared to a 24 month follow-up visit. There are also several additional time points from 3 weeks, 6 weeks, 3 months, 6 months and 12 months where the functional and clinical outcomes are assessed.
