Summary
Arthroscopic treatment for painful bipartite patella offers a safe and effective surgical option. Most patients experienced pain relief and returned to sports activities following the procedure.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Knee Arthroscopy
Background:
- Bipartite patella is a rare congenital condition causing knee pain after injury.
- Nonoperative treatments may fail, necessitating surgical intervention.
- Current surgical standards include open fragment excision or lateral release.
Purpose of the Study:
- To evaluate the safety and efficacy of arthroscopic procedures for painful bipartite patella.
Main Methods:
- A systematic literature review of studies published up to March 2020.
- Inclusion of all English-language human studies on arthroscopic treatment for bipartite patella.
- Exclusion of abstracts-only, nonsurgical, or unrelated diagnoses.
Main Results:
- Eleven articles involving 43 patients were analyzed.
- Arthroscopic lateral release was performed in 79% of cases.
- All patients, except one with re-injury, achieved pain relief and returned to sports within a mean of 2.6 months.
Conclusions:
- Arthroscopic management is a safe and effective alternative to open surgery for painful bipartite patella.
- The rarity of the condition limits evidence to case studies and small series.
- Future research should focus on higher-level studies comparing arthroscopic techniques and rehabilitation.
