Some patella (kneecap) fractures that remain in good alignment can be treated without surgery, protecting the knee in a straight position while the bone heals.
This page explains how a nonoperative patella (kneecap) fracture is commonly managed, in plain language, based on Dr. Kee's typical approach to this injury.
Every fracture is different. Treatment varies based on the exact fracture pattern, displacement, age, whether surgery is needed, bone quality, other injuries, and how an individual heals. This page is general education, not your personal treatment plan — always follow the specific instructions given to you by Dr. Kee's office.
Some patella (kneecap) fractures that remain in good alignment can be treated without surgery, protecting the knee in a straight position while the bone heals.
An intact straight-leg raise is a key part of deciding whether nonoperative care is appropriate.
This fracture is generally treated without surgery. Instead, it is protected in a cast, splint, or brace so the bone can heal in a good position on its own.
A knee immobilizer, worn for about 6 weeks.
Weight bearing as tolerated (WBAT) from the start.
For a full explanation of what these weight-bearing terms mean, see our Weight-Bearing Guide.
The knee is kept straight in the knee immobilizer for about 3–4 weeks. You'll then transition to a hinged knee brace locked from 0–50 degrees, increasing 10–20 degrees each week until reaching 90 degrees of flexion, at which point the brace can be discontinued.
Quadriceps activation and staged knee motion once stability is confirmed; therapy if motion or strength lags.
A 6–8 week X-ray to confirm healing. An optional 3–6 month X-ray may be used to monitor final healing.
Every fracture moves through the same general phases, though the exact timing is different for every patient:
Work or School: Desk work with brace; prolonged standing, kneeling, and climbing based on symptoms.
Sports or High-Risk Activity: Usually 10–12 weeks or longer after painless motion and extensor strength return.
Loss of active extension, displacement, increasing swelling, skin compromise, or neurovascular symptoms.

Your surgeon will guide when it's safe to return to these activities based on how your specific fracture is healing. Follow the instructions given specifically to you.
Every fracture heals differently. If you have questions about your treatment plan, reach out to Dr. Kee's office.
