The Knee Spike is an implant that gives an attack with 38% AP and 8.46 DPS. Like all Implant Weapons, it can only be installed on a natural limb, not a prosthetic or bionic limb.
Acquisition
The Knee Spike can be crafted at the Machining table once Compact Weaponry, which requires a Techprint, is researched. It requires 
40 steel, 7 components, 15,000 ticks (4.17 mins) of work, and a crafting skill of at least 5.
It can also be found on Raiders, bought at traders and acquired through Quests
Analysis
The Knee Spike is slightly superior to a steel longsword of normal quality, with 0.98x the DPS made up for by 1.15x the AP. This means it is a relatively powerful weapon early on, however as knee spikes are not affected by quality or material bonuses, their relevance for melee pawns diminishes in the mid game. They will still generally increase DPS by replacing or supplementing the weaker Handle attacks that occur 25% of the time, but the gain is small and the trade-off in bionics discussed below may not be worth it.
As ranged weapons typically fair poorly when used in melee combat and knee spikes can installed on pawns without preventing them from carrying ranged weapons, they can be useful to give a ranged pawn a decent melee option. This both expands their versatility in combat and mitigates a key weakness to melee enemies. However, the knee spike cannot be installed on bionic or archotech legs. The movement buff leg replacements provide can be key in improving pawn survivability, and are a significant boon in day-to-day duties. Therefore, installing the otherwise-inferior Elbow blade and forgoing a bionic or archotech arm may be a better option. As the effect of Manipulation on Shooting Accuracy is capped at 100%, the buffs provided by the arms do not significantly improve a ranged pawn's combat abilities, so it can be a more palatable trade-off assuming a pawn's non-combat duties would not benefit from heightened manipulation ability, such as hunters, haulers and cleaners. If both bionic arms and legs are preferred, Venom fangs offer both significantly lower DPS and AP than either of the other two but do not conflict with any other beneficial prosthesis.
As of the changes to melee verb selection in 1.1.2610, installing more than one knee spike is redundant in all but some very niche circumstances, as is installing more than one of the implant weapons.
