Sex With Bad Knees: How a Wedge Changes Everything
Bad knees affect tens of millions of people, and their impact on intimacy is rarely talked about. Kneeling on a mattress during sex — even briefly — puts compressive load on the knee joint. For anyone with arthritis, tendinitis, a previous injury, or post-surgical knees, this ranges from mildly uncomfortable to genuinely impossible. The result is a quiet narrowing of what feels accessible in the bedroom, often without either partner explicitly acknowledging what’s being avoided.
Which Positions Cause Knee Strain
Doggy style requires the receiving partner to maintain a kneeling position for the duration. The penetrating partner in most positions kneels on the mattress in some configuration. Partner-on-top positions require knee flexion under body weight. Even missionary involves one partner’s knees on the bed surface. Essentially, most common positions involve some knee loading — which means bad knees can affect nearly every position a couple relies on.
How the Wedge and Ramp Address This
For the receiving partner in rear entry: Instead of maintaining a hands-and-knees position, the receiving partner lies chest-down on the ramp with hips elevated. Zero knee load. Their legs are extended. The position is more comfortable than standard doggy style for most people regardless of knee issues.
For the penetrating partner: Using the wedge under the receiving partner’s hips in missionary means the penetrating partner can lower themselves forward rather than kneeling upright. Lying between the partner’s legs with weight on forearms rather than knees eliminates the kneeling load entirely.
Partner-on-top modification: The lying partner with a wedge under their hips can create the angle that reduces how much bend the partner on top needs to achieve the right angle of penetration. Less required knee flexion for the partner on top.
The ramp-and-wedge combo is specifically designed to allow sex without sustained kneeling positions. See it on Amazon.
Positions That Work Well for Bad Knees
Side-lying positions (spooning) with the wedge between the knees involve almost no knee load for either partner. The receiving partner’s upper knee is elevated by the wedge, which creates the access needed for side-entry penetration. Both partners are on their sides with weight distributed along their bodies.
Face-to-face lying positions with the wedge under the receiving partner’s hips and the penetrating partner lying rather than kneeling forward are also knee-friendly. The angle from the wedge makes this configuration functional where it might not be without elevation.
Long-Term Thinking
Many couples dealing with knee pain have gradually stopped certain positions without making a conscious decision about it. A positioning set is an opportunity to rediscover what’s possible when the physical constraints are engineered around rather than worked through. It’s not a workaround — it’s the right tool.

Frequently Asked Questions
Does the wedge completely eliminate knee pain during sex?
For most positions, yes — it removes the need for sustained kneeling. Side-lying positions with a wedge are nearly zero knee-load. Communication with your partner about what feels comfortable remains important.
What’s the best position for bad knees?
Spooning with a wedge between the knees, or the receiving partner over the ramp in rear-entry while the penetrating partner lies or stands. Both eliminate sustained kneeling.
I’ve had a knee replacement — is this safe?
Positioning furniture reduces load on the joint, which is generally positive for post-replacement recovery. Consult your surgeon about activity restrictions, but reducing knee load is typically the goal.
Can both partners have bad knees and still use this?
Yes — the configurations that work for bad knees are designed to take both partners out of sustained kneeling. Side-lying and ramp-supported positions work for both.
Does the ramp or wedge work better for knee issues?
The ramp is more useful for the receiving partner who would otherwise be kneeling. The wedge helps the penetrating partner avoid kneeling by enabling lying positions. Both are useful.
