Summary
Minimally invasive knee replacement surgery using the mini-mid vastus approach resulted in less pain and faster recovery compared to the traditional medial parapatellar method. Component placement was excellent in all cases.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
Background:
- Total knee replacement (TKR) is a common procedure for knee osteoarthritis.
- Surgical approach impacts post-operative outcomes.
- Minimally invasive surgery (MIS) aims to reduce tissue trauma.
Purpose of the Study:
- To compare outcomes of primary knee replacement using a mini-mid vastus MIS approach versus a standard medial parapatellar approach.
- To evaluate post-operative pain, recovery of flexion, and functional milestones.
Main Methods:
- Prospective study with retrospective matched cohort comparison.
- Utilized Genesis™ II implants and MIS instrumentation.
- Compared mini-mid vastus MIS incision (MMV MIS) with traditional medial parapatellar incision.
Main Results:
- MMV MIS group required less post-operative pain medication.
- Patients in the MMV MIS group regained flexion more rapidly.
- Functional milestones were achieved earlier in the MMV MIS group.
- Radiographically excellent component placement was observed in all cases.
Conclusions:
- The mini-mid vastus MIS approach for primary knee replacement offers advantages in pain management and functional recovery.
- Excellent component positioning is achievable with MIS techniques.
- Specialized instrumentation is beneficial for optimal MIS performance.
