McDavid 5125 Knee Sleeve with Dual Gel Buttress – 4-Way Stretch Compression for Patellar Support & Knee Stability

The McDavid 5125 Knee Sleeve combines 4-way stretch compression with a dual gel buttress that surrounds and supports the patella (kneecap) — providing targeted patellar tracking support, compression for knee joint warmth and recovery, and comfortable stability during sport and daily activity. The 4-way stretch fabric moves with the knee through its full range of motion while providing consistent compression. Available in Small through X-Large.

• Dual gel buttress — surrounds the patella for targeted patellar tracking support
• 4-way stretch compression — moves with the knee, maintains compression
• Supports patellar tracking and patellofemoral pain management
• Provides joint warmth for arthritis and post-injury comfort
• Available in Small, Medium, Large, X-Large

Frequently Asked Questions

What conditions is the McDavid 5125 most suitable for?

The 5125 is particularly suited for: patellofemoral pain syndrome (PFPS/runner's knee), chondromalacia patellae, mild patellar tracking dysfunction, knee pain during sport or exercise, post-knee injury activity support, mild osteoarthritis of the knee with patellar involvement, and general knee compression and warmth for recovery. For significant patellar instability or lateral patellar subluxation, the OPP1033 Patella Stabilizer (with rigid stays) provides more structural support.

How does the dual gel buttress support the patella?

The gel buttress forms a C-shaped or O-shaped channel around the patella — the soft gel material sits against the skin on either side of the kneecap, applying gentle medial and lateral pressure that guides the patella within its tracking groove during knee movement. This dynamic guidance reduces the lateral patellar displacement that causes patellofemoral pain without the rigidity of a hard brace.

How is the 5125 different from the McDavid 421 Knee Support with Stays?

The 5125 uses a gel buttress and stretch compression — providing gentle, dynamic patellar guidance and joint compression that moves with activity. The 421 uses rigid polycentric stays — providing firm structural medial/lateral stability particularly suited for ligament instability (MCL, LCL sprains). Choose 5125 for patellar tracking and compression; choose 421 for lateral ligament instability and joint stability.

How do I size the McDavid 5125?

Sizing is based on knee circumference at the mid-patella. Small: under 33cm, Medium: 33–37cm, Large: 37–41cm, X-Large: over 41cm. The sleeve should feel firmly supportive without cutting into the back of the knee or causing discomfort during full knee flexion.

Can I wear the 5125 during sport?

Yes — the 4-way stretch design allows full knee range of motion during running, court sports, and gym activities. The sleeve stays in place during dynamic movement and does not restrict activity. Many athletes wear it throughout full training sessions and competitions for ongoing patellar support.
