Pain Levels and Opioid Usage in Three Nerve Block Cohorts in Primary TKA

Comparison of Pain Levels and Opioid Usage in ACB + Periarticular Block vs. ACB + IPACK Block vs. ACB + IPACK + Periarticular Block in Patients Undergoing Primary TKA

The primary objective of this study is to compare effect of combined block of ACB (adductor canal block) with IPACK (Interspace between the Popliteal Artery and the Capsule of the posterior Knee) block and/or Intra-articular block in immediate postoperative and early postop rehabilitation and pain management in patients undergoing primary TKA. The secondary objective is to review both in-hospital and post-discharge pain levels and narcotic usage of primary TKAs, with a minimum 6-week postoperative follow-up.

2. Patient age is 22-89 at time of TKA surgery.
3. Patient agrees to participate as a study subject and signs the Informed Consent and Research Authorization document.
4. Patient is able to read and speak English.

Exclusion Criteria:

1. Patient is under the age of 22 or over the age of 89.
