A prospective, randomized comparison of open vs arthroscopically assisted ACL reconstruction

Area of Science:

• Orthopedics
• Sports Medicine
• Surgical Innovation

Background:

• Anterior cruciate ligament (ACL) injuries are common, necessitating surgical reconstruction.
• Both arthroscopic and open techniques are used for ACL reconstruction, with varying clinical outcomes.
• Standardized rehabilitation protocols are crucial for post-operative recovery.

Purpose of the Study:

• To compare the clinical outcomes of arthroscopic versus open ACL reconstruction.
• To evaluate differences in postoperative pain, function, and strength between the two surgical techniques.
• To identify any statistically significant advantages of one method over the other.

Main Methods:

• Prospective, randomized controlled trial with blinded patients and physical therapists.
• All patients received ACL reconstruction using the central one third of the patellar tendon graft.
• Key outcome measures included pain scores, range of motion, strength (Cybex II), thigh atrophy, and clinical stability tests at multiple time points.

Main Results:

• Arthroscopic ACL reconstruction demonstrated statistically significant improvements in 1-month range of motion (P < .05).
• Reduced thigh atrophy at 6 months postoperatively favored the arthroscopic technique (P < .05).
• Superior knee extension strength at 60 degrees/sec was observed with arthroscopic ACL reconstruction (P < .05).

Conclusions:

• Arthroscopic ACL reconstruction offers advantages in early range of motion, reduced muscle atrophy, and improved strength compared to open reconstruction.
• The findings support arthroscopic ACL reconstruction as a potentially superior surgical option.
• Further research may explore long-term functional differences and patient-reported outcomes.
