Summary
Polypropylene mesh augmentation for quadriceps rupture after total knee arthroplasty (TKA) showed limited functional improvement but significantly reduced postoperative pain. This synthetic mesh approach warrants further investigation for multiply operated knees.
Area of Science:
- Orthopedic Surgery
- Biomaterials in Reconstruction
- Total Knee Arthroplasty (TKA) Complications
Background:
- Polypropylene mesh is established for patellar tendon repair post-TKA.
- Limited data exists on its use for complete quadriceps rupture after TKA.
- Quadriceps rupture is a severe complication following TKA.
Purpose of the Study:
- To evaluate the efficacy of polypropylene mesh augmentation for complete quadriceps rupture after TKA.
- To assess functional outcomes and pain relief in patients undergoing this reconstructive procedure.
Main Methods:
- Retrospective review of seven cases (six patients) with complete quadriceps tears post-TKA.
- Quadriceps tendon repair using suture and polypropylene mesh augmentation.
- Knee Society Score (KSS) and radiographic evaluation pre- and post-operatively.
Main Results:
- Four out of seven knees achieved clinical success (extensor lag < 30°).
- Significant improvement in extensor lag (50° to 20°, p=.01) and KSS for function (p=.03) and pain (p=.02).
- Mean postoperative flexion was 115°.
Conclusions:
- Polypropylene mesh augmentation provided limited functional recovery for quadriceps rupture post-TKA.
- Significant improvement in postoperative pain was observed.
- This technique may offer benefits for pain management in complex cases.
